[fw-general] How to check the SQL string created by Zend_Db_Select?
Hi, How can we check the SQL string created by select? for example: given this $select-where ( conditions); $select-orwhere ( conditions); $select-order ( conditions); I want to check the complete SQL statement it has created Zend_Debug::Dump($select) doesn't provide what I wanted to know.

[fw-general] Zend_Paginator's totalItemCount property question?
Hi all, When trying to access the totalItemCount property of Paginator, I am getting this error: == Notice: Undefined property: Zend_Paginator::$totalItemCount == Is this bug? Problem elaboration === before using paginator, my following view script logic was working perfectly: ? if ($this-myentries): ? ? foreach ($this-myentries as $entry): ? //show the entries ? endforeach ? ? else: ? h1Sorry! There are nothig to display for this search/h1 ? endif ? ** now I am passing paginator to this view script and the problem is ELSE part is not working anymore even if no entries are fetched. Result page shows nothing (no message). Instead it hangs my server. I tried to use the totalItemCount property to check if paginator really have some items before passing it to view script OR I tried to use the totalItemCount in viewscript itself ? if ($this-myentries-totalItemCount !== 0): ? in both cases, i am getting the error notice. Any suggestion on this? What is the correct way to make this logic work again? Thanks === Registered Linux User #460714 Currently Using Fedora 8, 10 ===
Re: [fw-general] Form values and paginator question
2009/2/17 Paweł Chuchmała pawel.chuchm...@gmail.com:
In mypaginator.phtml, you have something like that:
a href=?= $this-url(array('page' = $page)); ?
?= $page; ?
/a
You must cznge parameters for $this-url(). For example:
a href=?= $this-url(array_merge(array('page' = $page),
$this-dataForPaginatorUrl)); ?
?= $page; ?
/a
And in controller:
$this-view-dataForPaginatorUrl = array('searchstr' = $searchstr,
'adlocation' = $adlocation);
or something else.
regards,
pch
Doing this gives me an Warning like this:
==

but i am sure it is array and I have verified that.

[fw-general] Is parameter value disappears on the way?
hi,
Tracing my previous problem on why I cannot paginate with paginator, I
found out that the value I passed from controller to model is not
interpreted properly.
supposing clicking next button in paginator control, i got this url
http://myweb/index/index/page/2
In my controller
$request = $this-getRequest();
$pgreq = $request-getParam('page');
=
returns the expected value (2 in this case and I have verified this).
but I didn't understand why this values passes as function parameter
is not working inside the model function
so In my model function I have a code like this
==
public function fetchAllEntries($page=null)
{
$table = $this-getTable();
$select = $table-select()-order('newsdate desc');
$pgadapter = new Zend_Paginator_Adapter_DbTableSelect($select);
$paginator = new Zend_Paginator($pgadapter);
$paginator-setItemCountPerPage(5);
if ($page == null)
{
$paginator-setCurrentPageNumber(1);
}
else
{
$paginator-setCurrentPageNumber($page);
}
return $paginator;
}
public function getTable()
{
if (null === $this-_table) {
require_once APPLICATION_PATH . '/models/DbTable/NewsTable.php';
$this-_table = new Model_DbTable_NewsTable;
}
return $this-_table;
}
the problem lies in
$paginator-setCurrentPageNumber($page);
(This is not working)
If I try to set he page manully like
$paginator-setCurrentPageNumber(3);
It is working
Can somebody tell me where is my blunder mistake?

1. Controller gets the form parameters through getValues() and pass

2. Model (which have access to DBTable) will dynamically generate
query based on user's criteria and initialize the paginator and
returns to Controller.

[fw-general] Another Zend_paginator Question
Hi, So far I am able to use the Zend_Paginator to display the limited results but I cannot forward through pages yet. I guess I need to track the page number request from paginator control (either through URL or using Zend_Controller_Router_Interface) but before doing that I have some questions. 1. Where should be the paginator control file (mypaginator.phtml)? currently my paginator control phtml file is in the same view script as my index.phtml. 2. Currently I have managed to display the paginator control but when I click next, my url changes from http://myweb/ to http://myweb/index/index/page/2. Why there are two index in my url? Isn't that it should be http://myweb/page/2 only? 3. How to track page request from paginator control through URL? Documentation recommends (although not necessary) the use of 'Zend_Controller_Router_Interface'. Can somebody give me some hints on how to use this? Which is better?

Re: [fw-general] Another Zend_paginator Question
You are PHPScriptor. Arn't you? I like your answering style :-)
In the same directory I think you mean.
Yes. so that means what I am doing is fine.

$router = $frontController-getRouter();
$router-addRoute(
'news',
new Zend_Controller_Router_Route('news/:page',
array('module'='news', 'page' = 1, 'controller' = 'index', 'action'
= 'index'))
);
}
this is giving me something like http//localhost/news/page/2 ('page' = 1 is
set 'cause I want to start at this page :-))
Where this function should go?
bootstrap.php?
In the controller?
model?

Hi there,
the problem is that array_splice doesn't care about your string keys.
The manual states that array_splice($input, 0, 0, array($x, $y)) is identical

So, instead use array_merge or the + operator:
$locations1 = array_merge(array('Any' = 'Any'), $locations);
$locations2 = array('Any' = 'Any') + $locations;

[fw-general] Zend_Paginator Question
Hi, Short and quick question: I need some background and hint on how to use Paginator in strict Zend Framework MVC convention? (no customization) also some insight on Zend_Controller_Router_Interface. I cannot find enough information in documentation to grasp this. Long Question: = Currently my implementation is like this (for inserting updating data): Controller - Model - DBTable Now I am trying to implement search part and found out about Paginator, which is a cool thing to implement for lots of results. I need some hint on how to implement this in my current implementation (staying strictly within the ZF MVC convention)? I need some overview on where things get initialized plus how data is accessed etc. Actually based on what I am going to implement, I guess I need to manipulate the 'Select' in my controller (which changes based on user's criteria) but currently I am delegating dirty works to Model. If I delegate this to model then where do I initialize the Paginator and feed the Select? etc. Sorry currently my view on Paginator is still blurred and I don't know if I am asking the right question.

I don't know if this will answer your question, but this is how I do it:
The paginator is set in the controller. I think you could do it in the
model, but that would make things a lot complicater.
Where to define your select, where,... 99% I do in the controller. 'Cause if
not, you need to pass all your values to the model.
Thank you this is what I exactly want to know about how things get
orchestrated. This time you read my mind. :-)
$NewsModel = new News_NewsModel();
$select = $NewsModel-select();
$select-order('newsdate DESC');
$select-where('id5');
$news = $NewsModel-fetchAll($select)-toArray();
$paginator = Zend_Paginator::factory($news);
$paginator-setCurrentPageNumber($this-_getParam('page'));
$paginator-setItemCountPerPage(5);
$paginator-setPageRange(10);
$this-view-news = $paginator;
The 'order' and 'where' can also be done in a model-function. But why
creating an extra function just for 2 conditions. So I do it in my
controller.
Thanks for the example too. But small question (unclear to me).
do I need to fetch all before feeding to paginator? or I will feed the
select itself?
what I understood from documentation is if used with Zend_db_select it
will just fetch the necessary rows only. So what is the advantages and
disadvantages in this two approach? or what are the best practices
(blah)
This is what I think (please correct me if I am wrong):
==
1. If fetchall is used, we don't need to requery the db; just move
back and forth between already fetch data.So new entries after
fetchall operation will not be reflected in the serach result.
2. If we feed select to paginator, it will requery db everytime we
move back and forth plus it is possible to see the new entries made
after query when we go back (i.e, what I saw in first page can move to
second page after a while when I come back again to first page)
==
Is this true?
I am asking about this from the performance aspect
If one approach has advantage over another, can you tell me what are they?
I like your explanation. Its straight to the point.
Plus can you give me some info on Zend_Controller_Router_Interface
about how it works.
Thanks again.

[fw-general] [OT-PHP] Insert an associative array at beginning
Hi,
I got confused on why this is not working.
I have an array of locations stored in $location variable which is
fetched using fetchPairs(). I wanted to add and element Any = Any
at the beginning of this $location.
so my $locations is [from Zend_Degug::Dump($locations)]:
=
array(3) {
[location1] = string(9) location1
[location2] = string(9) location2
[location3] = string(9) location3
}
=
I used:
===
array_splice($locations, 0, 0, array(Any = Any));
Expecting:
array(4) {
[Any] = string(3) Any
[location1] = string(9) location1
[location2] = string(9) location2
[location3] = string(9) location3
}
But I am getting:
array(4) {
[0] = string(3) Any
[location1] = string(9) location1
[location2] = string(9) location2
[location3] = string(9) location3
}
Why?
Thanks

[fw-general] Why $form-getValue() is not working?
Hi,
I am trying to implement a simple search function. For the test
purpose I am trying to display the search string in my view. This is
how it looks like:
my form
--
class Form_Search extends Zend_Form
{
public function init()
{
//create search text input element
$qsearch = New Zend_Form_Element_Text('qsearch');
$qsearch -setLabel('Quick Search');
$qsearch -setAttrib('size', '40');
$qsearch -setRequired(true);
$qsearch -addFilter('StringTrim');
$qsearch -addValidator('NotEmpty',true);
$qsearch -addValidator('Alnum', true);
$qsearch -addErrorMessage('Invalid search string');
// add the submit button
$submit = New Zend_Form_Element_Submit('submit');
$submit-setLabel('Search');
//add the elements to form
$this-addElements(array($qsearch, $submit));
}
}
--
my controller
-
public function indexAction()
{
$request = $this-getRequest();
$form = $this-_getSearchForm();
$this-view-form = $form;
if($request-isPost())
{
if ($form-isValid($request-getPost()))
{
$strinput = $form-getValue('qsearch');
$this-showQuickSearchResult($strinput);
}
...
...
private function showQuickSearchResult($searchstr)
{
$this-view-searchstr = $searchstr;
}
-
my view script
---
div id=quicksearch
?= $this-form ?
/div
div id=check
? if ($this-searchstr): ?
h2search string is: ? $this-searchstr ?/h2
? endif ?
/div
-
My problem is the search string I entered in the form doesn't get
shown. Its blank.
Why?
What's wrong with this code?
Isn't this how we get the value from the Form?

I agree with you on this. I also came up with similar logic that if
getPost() is not working then validators should also not work; however
I noticed that my validators are working perfectly.
I entered the string 'checking' in form did var-dump of
$request-getPost() and got this:

array(2) {
[qsearch] = string(8) checking
[submit] = string(6) Search

So that means its working.

[fw-general] How to display validator specific error message in Zend_Form?
Hi,
I have text element in the form with two validators
+---
$mytext= New Zend_Form_Element_Text('mytext');
$mytext-setLabel('Enter Text:');
$mytext-setAttrib('size', '40');
$mytext-setRequired(true);
$mytext-addFilter('StringTrim');
$mytext-addValidator('NotEmpty');
$mytext-addValidator('Alnum');
+---
I tried general error message to this text element like this:
$mytext-addErrorMessage('Invalid Text');
but when I try to submit the form without entering a thing, this error
message is displayed twice.
After that I tried:
$mytext-addErrorMessages(array('NotEmpty' = 'String cannot
be empty', 'Alnum' = 'Invalid string'));
Hoping this will assign the specific error to each validator, but when
I submit the empty form, now it displays the message four times.
What I actually wanted to do is:
*
Empty string will be checked first and shown error message ignoring
other validators. So if the string is empty show the error message for
empty string validator and exit from validator chain ignoring other
validators in the sequence. But it seems all validators are active
each time.
*
1. how do I do that?
plus
2. how to set the error message for specific validator so that only
that message will get displayed instead of all the error message

Re: [fw-general] Form layout update didn't get reflected
Hmm, I tried it, and seems to be working fine... You didn't use decorators? Did you look at your html source output? Did you try cleaning up your browser history? Everything is default from ZF. No decorators. Yes html source shows the previous order of elements. Yes in my firefox setting it cleans up everything when I exit browser I tried in Internet Explorer also and got the same result. My suspicion is not at the client side but at the server. It seems like server is caching and serving the same file. I know if I use smarty template engines, it is possible to compile and cache the templates for the faster response time. That's why I am asking if ZF's view template also does that behind the scene by default? Right now I am very new to ZF and trying to understand its internal working. In fact the web I am building is based on the quickstart file in the documentation. I am just expanding (modifying) it to study different aspects.

Re: [fw-general] Populating Zend_Form_Element_Select from database example
Yes, add a setter method for attaching the model to the form and then do
this in the controller. The form will then have access to the model to
retrieve any data it needs.
You can also populate the element directly in your controller by retrieving
it from the form and manipulating it e.g. $form-getElement('some
element')-setMultiOptions(some array).
so what is the use of populate and setDefaults functions?
both are used to set the values of the elements, there no difference between
the two.
Ok, this is the type of explanation I am looking for. Now I understand
how to manipulate form from controller. I guess the later method is
suitable for me on what I am trying to do.
Now I understand why we were not able to understand each other. It is
because I was looking for a way to populate the form elements.
Initially I thought of creating the variable in form class and getter,
setter methods but when I dug around a bit, I found the explanation in
the documentation
http://framework.zend.com/manual/en/zend.form.forms.html#zend.form.forms.elements.values
which knocked me off from the right track.
From the documentation, what I understood is $form-populate($data) is
the way to send the data to the form for manipulation (not setting the
value in already populated element). I thought that it is part of the
ZF's behind the scene magic where form knows what data have been
passed by the controller.
Anyway it is nobody's fault but the documentation is somewhat
misleading. If you think of it naturally, populate is synonymous with
populating database tables (not selecting an particular item).
Now its all clear and I have tried the second method and it works but
with a minor problem which I still don't understand. I will be posting
that problem in next thread since this part is solved already.
Thank you both for being very patient with me.
Regards

[fw-general] Array Index included question?
hi,
I am not sure if this is related to ZF but anyway I am asking it here.
I have a one column table (called location) in my database.
++
| locname | this is also the primary key
++
| location 1 |
++
| location 2 |
and so on
In my model, I have
==
public function fetchEntries()
{
$table = $this-getTable();
$select = $table-select();
return $table-fetchAll($select)-toArray(); // THIS IS
MY SUSPECT
//OR
//return $this-getTable()-fetchAll('1')-toArray(); //
OR THIS ONE
}
==
In my DBTables, I have
===
?php
class Model_DbTable_LocationTable extends Zend_Db_Table_Abstract
{
/** Table name */
protected $_name= 'location';
protected $_primary = 'locname';
}
===
In my Conroller, I have
=
public function indexAction()
{
$request = $this-getRequest();
$form= $this-_getTestForm();
$modellocation = $this-_getLocationModel();
$locations = $modellocation-fetchEntries();
$form-getElement('adlocation')-setMultiOptions($locations);
...
...
...
=
In my Form, i have
$location = New Zend_Form_Element_Select('location');
$location-setLabel('*Location:');
$location-setRequired(true);
=
Everything goes fine and form renders with the Location populated but
with one problem. Array index is also shown in location listing
although it cannot be selected.
something like this:
=
Location:
0 ( cannot be selected)
Location 1 (can be selected)
---
1
---
Location 2
---
and so on
To test this, I have created an array in my controller and tried
passing it in the form.
public function indexAction()
{
$request = $this-getRequest();
$form= $this-_getTestForm();
$modellocation = $this-_getLocationModel();
//$locations = $modellocation-fetchEntries();
$locations = array( 'rat', 'cat', 'hat');
$form-getElement('adlocation')-setMultiOptions($locations);
...
...
...
=
and this works fine and renders fine in the form without any index.
So that means I am really getting extra stuff when 'fetchEntries()' is
being called. Can somebody tell me what is wrong? what am I missing?
Thanks

[fw-general] Populating Zend_Form_Element_Select from database example
Hi,
I am confused on how to populate the Select element from database. In
the Select element I need to fill it with location data which is
stored in database as single field table (each item is unique)
location
--
location1
location2
location3
...
... etc.

There is very little stated in the documentation about
form-populate($data) so I am confused on which goes where.
Can somebody illustrate its mechanics step by step conceptually? In
particular when I pass the $data variable how do I access that in
the form
1. defined as global variable for this form class? OR
2. directly use that variable when creating form element? something like
===
$location = New Zend_Form_Element_Select('adlocation');
$location-setLabel('*Location:');
foreach($data as $loc)
{
$adlocation-addMultiOption($loc, $loc);
}

can somebody suggest me how to fill up this element?

Re: [fw-general] Populating Zend_Form_Element_Select from database example
It looks like your doing it correct except for the array of data that you're
using to populate the form. You're not actually populating the select
element with options, you only want the current Or selected option to be
selected in the select list on display.
So in your case it's probably a location id,
$data = array(
'location_id' = 2
);
$form-populate($data);
Change location_id to whatever the id of the select element is.
Ok, just help me in this part
As I mention i my first post, I have table called location with field
locname as only field and also the primary key for that table (there
is no locationid, locname).
so If I retrieve data from that table (to array) I will have array of locations.
e.g. $data = array('location1', 'location2', ... and so on);
in my form, if I have to hand code to fill the select, I will be doing
something like this:
$location= New Zend_Form_Element_Select('location');
$location-setLabel('*Location:');
$location-setMultiOptions(array('location1' = 'location1',
'location2' = 'location2' and so on));
My question is how do I do the same thing with the previous method (
controller passes the retrieved data to form and form will iterate to
populate data in select element).
I guess it is clear now.

Yes that works! and I understand what you mean about this but that is

to populate the select element in the form from database rows? not
how to select the item in the already populated select element.

I want to fill this $location automatically from database. How do I do that?
what I understood from the link you provided me is
1. I am going to manipulate the model from the form class itself (is
this true?) so that means there is no controller involved and form
have the knowledge of how to manipulate tables directly (which should
not be if we follow the MVC pattern).
But instead
1. I want to separate the datasource itself from the form.
2. What I wanted to do is Controller will be responsible for fetching
the data from the model and pass an array to the form. Form have no
knowledge of how that data arrives there but knows that something have
been provided by controller for it to manipulate. So in my case
controller provides the location array to form and form will populate
the Zend_Form_Element_Select before showing it.
3. The part I wanted to know is how this mechanism works (or how to
make that happen)?
That's why I asked in my first post:
a) Do I need to declare global variable in my form class plus getter,
setter methods so that Controller can set that variable through those
methods and I can use the data provided in that variable?
b) or when controller uses $form-populate(some array), the form
already have knowledge of what's being passed to it? If so how the
form will knows what to reference?
If I understand this then I know what I am looking for and can figure
out how to write the code I need.
Please correct me if I am wrong about my concept.
Now can you explain how this works and how to make that happen in
plain English (no code involved)
Thanks

Hi, me again it is solved now by doing this == $captchaimg-setMessage(My Custom Message, 'badCaptcha'); == This came to my mind only after I did some digging around and had a look at the code 'Zend/captcha/Word.php' (ancestor class) Where the message template and keywords are defined = const MISSING_VALUE = 'missingValue'; const MISSING_ID= 'missingID'; const BAD_CAPTCHA = 'badCaptcha'; /*...@-*/ /** * Error messages * @var array */ protected $_messageTemplates = array( self::MISSING_VALUE = 'Empty captcha value', self::MISSING_ID= 'Captcha ID field is missing', self::BAD_CAPTCHA = 'Captcha value is wrong', ); == Thanks anyway -- === Registered Linux User #460714 Currently Using Fedora 8, 10 ===
[fw-general] Zend_Captcha custom error message question
Hi,
Breaking from previous post, I am posting this as a new subject.
I am using Zend_From to display captcha with custom error message.
When I make a wrong entry (intentionally), my custom error message is
not shown when form validates.
Sample code:
//first create an captcha image
$captchaimg = New Zend_Captcha_Image('captchaimg');
$captchaimg-setFont(../application/captcha/fonts/tahoma.ttf);
$captchaimg-setImgDir($_SERVER['DOCUMENT_ROOT'] . '/images/captcha/');
$captchaimg-setImgUrl(/images/captcha/);
$captchaimg-setWordlen('6');
//create user input for captcha and include the captchaimg in form
$adcaptcha = New Zend_Form_Element_Captcha('adcaptcha', array(
'captcha' = $captchaimg));
$adcaptcha-setLabel('Please enter the letters displayed below:');
$adcaptcha-setRequired(true);
$adcaptcha-addErrorMessage('Entered value did not match with
displayed image.'); this part
===
I have checked the HTML code through view source (after validation).
My error message is nowhere to be found in final HTML.
Question:
1. Is my way of setting custom error message correct?
2. If yes, why it is not shown? what else needs to be considered?
===
Thanks

[fw-general] Re: How to use Image based Captcha?
Hi,
I found out that image is being generated. Also because of
$captchaimg-generate(); command its being generated twice.
So I replaced the 'generate()' with $captchaimg-setWordlen('5');
Now I can see that every time I display the form page, new image is
generated in the 'captcha/images' folder (which are valid images) but
its not displayed inside the form.
What is wrong?
Thanks

[fw-general] Zend_Form or Captcha bug?
Hi,
Didn't get any help from my last post so I went through documentation
and tried to understand as much I can but can't find a way to display
captcha image in Zend_Form using default behavior of Zend Framework's
MVC. AFAIK (with my current knowledge), my code is correct.
This is the code snippet in my [application/forms/myform.php]
===
//first create an image type captcha
$captchaimg = New Zend_Captcha_Image('captchaimg');
$captchaimg-setFont(../application/captcha/fonts/tahoma.ttf);
$captchaimg-setImgDir(../application/captcha/images);
$captchaimg-setImgUrl(../application/captcha/images);
$captchaimg-setWordlen('6');
//create user input for captcha and include the captchaimg in form
$adcaptcha = New Zend_Form_Element_Captcha('adcaptcha', array(
'captcha' = $captchaimg));
$adcaptcha-setLabel('Please enter the 5 letters displayed below:');
$adcaptcha-setRequired(true);
$adcaptcha-addErrorMessage('Entered value did not match with
displayed image.');
$this-addElements( array($adcaptcha));
=
My view script:
?= $this-form ?
dirctory structure for captcha image is:
=
application
- captcha
- fonts
- images (for genreated images)
=
My Observation
===
1. There is no captcha image when form renders. However, I can see
image being generated in 'application/captcha/images' folder.
2. Trying to post the empty form (expecting that my custom error
message will be displayed) gives me empty error message string with
just a round bullet list in the captcha section but other text input
fields show the correct error messages.
3. Using view source in the browser, i got this about captcha

My Questions:
1. The image url was passed to the brower but why it didn't get
rendered in the form?
2. Is this the bug or feature? If it is the feature, how do I make the
image appear in my form using the code I have posted above? what are
the additional things I need to consider?
Partial answer (best guess) to my own question:
1. Probably form is forgetting to call some default rendering function
of Zend_Captcha to render it (or ???). However custom approach (with
custom form) as shown in zend documentation
[http://framework.zend.com/manual/en/zend.captcha.operation.html] and
the one I found in recent blog [http://www.tfountain.co.uk/] works
because it explicitly calls echo $captcha-render($view); method.
But I want to stick with ZF's default MVC behaviors and want to
understand how these pieces fit together before I can understand and
do customized stuffs. So I need to show the captcha image suing zend
form.
Can somebody guide me about whether it is bug/feature? and any workaround?
Thanks a lot

[fw-general] How to use Image based Captcha?
Hi,
I am absolutely new to ZF. Right now I am playing around with the
Quickstart files. So far I am bit comfortable with the concepts. Now
I want to change the provided zend captcha (figlet) into image type
but can't find any example of this in the zend documentation.
This is what I came up with
$mycaptcha = New Zend_Form_Element_Captcha('mycaptcha');
$mycaptcha -setLabel('Please enter the 5 letters displayed below:');
$mycaptcha -setRequired(true);
$mycaptcha -setCaptcha('Image', array(
'font' = 'C:\WINDOWS\FONTS\TAHOMA.TTF',
'imgdir' = APPLICATION_PATH . '/images/captcha'
));
I have created the images/captcha folder inside the application path
and expecting to show up the label and image but instead it shows an
unrelated error.
Error message:
==
An error occurred
Application error
Exception information:
Message: Invalid validator provided to addValidator; must be string or
Zend_Validate_Interface
==
if I remove the captcha element from the form it works fine.
What is wrong with my code? and where should I look for more
information on this?
Any suggestions/guidance?
Thanks!

[fw-general] Re: How to use Image based Captcha?
After reading the list archive
http://www.nabble.com/Zend_Captcha-td20300142.html#a20300142 , I
figured out my mistake. Now I have made changes and code looks like
this
...
...
...
//first create an image type captcha
$captchaimg = New Zend_Captcha_Image('captchaimg');
$captchaimg-setFont(APPLICATION_PATH . '/captcha/fonts/tahoma.ttf');
$captchaimg-setImgDir(APPLICATION_PATH . '/captcha/images');
$captchaimg-generate();
//create user input for captcha and include the captchaimg in form
$adcaptcha = New Zend_Form_Element_Captcha('adcaptcha', array(
'captcha' = $captchaimg));
$adcaptcha-setLabel('Please enter the 5 letters displayed below:');
$adcaptcha-setRequired(true);
...
...
...
As you can see, i have copied the font to application itself. Now form
displays with Please enter the 5 letters displayed below but no
image is shown.
Checking in '/captcha/images' shows no image have been generated.
Isn't that this folder should have generated images?
What is wrong now?
Please can somebody guide me.
Thanks

[fw-general] quickstart tutorial create layout help
Hi,
I am completely new to ZF and following the quickstart guide. It was
doing OK until I reached the part Create Layout section
(http://framework.zend.com/docs/quickstart/create-a-layout) my page
start to show something unusual. I cannot understand this yet.
Things that might help:
-
1) I am using Apache 2.2.11, PHP 5.2.8, latest ZF 1.7 in windows xp
2) quickstart is hosted as virtual host
-
[http://quickstart] shows:
===
doctype() ? headLink()-appendStylesheet('/css/global.css') ?
ZF Quickstart Application
Guestbook
layout()-content ?

Cannot find any error logged by apahce.
Any explanation/suggestion is greatly appreciated.
