Re: CakePHP programming problem
In general, read up about MVC as anselm said earlier http://en.wikipedia.org/wiki/Model-view-controller is one site, but there are a whole slew of other sites which provide descriptions which should give you an overall view of what Cake is trying to achieve. Hopefully, I have covered all your questions above. 1. Is there a formal thing called a "page template" and this is meant to invoke its known properties? Also, is "action" a defined formal term for something? A page template is a layout. It is the framework into which all your content goes. You have a default layout, and each action may instead define that it uses a different layout. An action is a function in a controller class which basically becomes the second item in a URL - http://www.sitename.com/myControllerName/actionName/param1/param2/... -where param1 and 2 etc are optional, and if you do not have an action, it calls the index function in your controller. 2. What does "PostsController::add()" represent? It represents a coll to the add funciton in the PostsController class when you visit URL www.sitename.com/posts/add 3. What do you do with these files (view files)? You define what the output to the browser is for the particular action. 4. Is that supposed to mean something, the "view template file"? Is that the verb "to view the template file"? Then we have something called a template file and there s a file that when executed displays it? Where is this explained? The template file is a file in the view directory. Any of the files endin thtml are template files and they define in mixed HTML/PHP what output is being provided to the browser. 5. How do you do that and why (you can use the data from the corresponding Model. This data is passed as an array called $data. )? The Model class is your interface to the database table named after the model. Any data in that table is available via the data array. 6. What does "using set" mean? In your controller, you can use the function $this->set to allow you to make data available to your view. The view can see no other data. 7. What are HTML helpers? These are functions which are designed to make your job of editing the thtml files and outputting HTML easier. 8. How can I see a list of all of these functions with explanations? Look in api.cakephp.org The source code is available and can be read. 9. What does "default layout" mean? Answered above. 10. Why do we create a layout and where does t explain how to? So you can define your page. 11. What kind of thing is $content_for_layout? And why is $title_for_layout optional? $content_for_layout is a string containing all of your output data. It is where what you have defined in your view thtml file goes in your layout. $title_for_layout allows you to set a custom title for a page. It is not required, but useful. 12. What is a controller variable? A variable defined in a controller class. 13. What is the controller's $layout variable and setLayout() function? Allow you to override the default layout and provide a layout specific for this controller or action. 14. What does it mean to give an element access to data, and to send it as a named parameter in an array? Elements do not see any data by default. You have to add an extra array as the second parameter to render_element which contains a list of parameters and their names. 15. What in general do you input into CakePHP? How do you use it after you do all the input to set it up? What are the options that you can use in order to run the application then? Whatever your want to do. Call the controller and action using the URL of your page and it will run the code in that controller.

I think I see *my* problem with your questions here: you are using
terminology which I find confusing ("developed an expression" and the
use of "chores" as a label to describe input). Hence my apparent
inability to understand the questions you are asking
# 1. I mean expressions as in PHP expressions that make up PHP code,
composed of constants, operators and functions. Programmers know that
most inputs into most applications are single values (e.g. a person's
first name) rather than an expression that combines multiple values.
And they also know the power of systems that allow you to input an
expression e.g. to define input data validation.
What I did was to apply the concept to defining the syntax of an HTML
page so a general purpose parser can take an HTML file plus the
expression that defines the format of the data presented in that HTML
and extract that value. I developed this system in PHP and MySQL.
# 2. By chores, I don't mean input. I mean the general sense of what
you must do to get something done. I am asking the general question of
what you do to set up an application: enter data into forms, modify
files with PHP code in them, copy functions that you have written into
existing CakePHP files, etc. That is why I used the general word
"chore" - to represent all of the types of things that you do.
I am seeing that you must create files of PHP code to define parameters
(e.g. validation of fields) rather than entering it into a form.
If there is a link to something that answers these questions, then I
would like to see it. All I have found is low level descriptions with
all of the details, and no high level overall summary of how CakePHP
works. It is always best to start at the highest level of abstraction
and work your way down, whether it is an explanation or problem-solving
in general.

are clear?

Re: CakePHP programming problem
1. Is there a formal thing called a "page template" and this is meant to invoke its known properties? Also, is "action" a defined formal term for something? I think you are trying too hard. You seem to approach programming as one would approach mathematics - wanting everything to be formally defined. CakePHP is a framework for Rapid Application Development - which works much more on intuition and tacit understanding than formal definition. Relax. Read what you can on MVC (http://en.wikipedia.org/wiki/Model-view-controller). Go through the Cake Blog tutorial. It's here : http://manual.cakephp.org/appendix/blog_tutorial . It tells you exactly what to do. At first, you might not understand _why_ things work the way they do. That's fine -- take it easy. Just do it, and see it running. Then modifiy it. Adapt it. This way you will slowly build your intuition. Next step, write your own small application based on the intuitive understanding you gained. Again, it does not matter if you don't exactly understand why things work the way they do. When you get to something you don't know how to do, check this group's archive ; likelyhood is it's been answered before. If you're not quite sure how a function behave, read it's code. That's the best way to learn (the code of CakePHP is the closest thing you'll get to a formal defintion - it's well written and very readable). Before you know it, you will have build a intuitive understanding of CakePHP, and you will know why and how things work. And this understanding will be usefull beyond CakePHP - it will apply to MVC web frameworks in general. If you can't work that way, then maybe Rapid Application Development is not for you !

anselm wrote:

If you want your button to appear on all pages at the same place, then
the easiest is to put the button as part of your layout. Your default
layout goes in app/views/layout/default.thtml -- see this part of the
manual to lear more about views and about layouts :
http://manual.cakephp.org/chapter/views
I have some questions (numbered):
CakePHP: The Manual
Views
Section 1
Views
A view is a page template, usually named after an action.
1. Is there a formal thing called a "page template" and this is
meant to invoke its known properties? Also, is "action" a defined
formal term for something?
For example, the view for PostsController::add()
2. What does "PostsController::add()" represent?
would be found at /app/views/posts/add.thtml. Cake views are quite
simply PHP files, so you can use any PHP code inside them. Although
most of your view files will contain HTML, a view could be any
perspective on a certain set of data, be it XML, and image, etc.
3. What do you do with these files?
In the view template file,
4. Is that supposed to mean something, the "view template file"?
Is that the verb "to view the template file"? Then we have
something called a template file and there s a file that when executed
displays it? Where is this explained?
you can use the data from the corresponding Model. This data is passed
as an array called $data.
5. How do you do that and why?
Any data that you've handed to the view using set() in the controller
6. What does "using set" mean?
is also now available in your view.
The HTML helper
7. What are HTML helpers?
is available in every view by default, and is by far the most commonly
used helper in views. It is very helpful in creating forms, including
scripts and media, linking and aiding in data validation. Please see
section 1 in Chapter "Helpers" for a discussion on the HTML helper.
Most of the functions available in the views
8. How can I see a list of all of these functions with explanations?
are provided by Helpers. Cake comes with a great set of helpers
(discussed in Chapter "Helpers"), and you can also include your own.
Because views shouldn't contain much logic, there aren't many well used
public functions in the view class. One that is helpful is
renderElement(), which will be discussed in section 1.2.
Layouts
A layout contains all the presentational code that wraps around a view.
Anything you want to see in all of your views should be placed in your
layout.
Layout files are placed in /app/views/layouts. Cake's default layout
9. What does "default layout" mean?
can be overridden by placing a new default layout at
/app/views/layouts/default.thtml. Once a new default layout has been
created, controller view code is placed inside of the default layout
when the page is rendered.
When you create a layout,
10. Why do we create a layout and where does t explain how to?
you need to tell Cake where to place your controller view code: to do
so, make sure your layout includes a place for $content_for_layout (and
optionally, $title_for_layout).
11. What kind of thing is $content_for_layout? And why is
$title_for_layout optional?
Here's an example of what a default layout might look like:
http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";>
http://www.w3.org/1999/xhtml";>
...
...
To set the title for the layout, it's easiest to do so in the
controller, using the $pageTitle controller variable.
12. What is a controller variable?
class UsersController extends AppController
{
function viewActive()
{
$this->pageTitle = 'View Active Users';
}
}
You can create as many layouts as you wish for your Cake site, just
place them in the app/views/layouts directory, and switch between them
inside of your controller actions using the controller's $layout
variable, or setLayout() function.
13. What is the controller's $layout variable and setLayout()
function?
For example, if a section of my site included a smaller ad banner
space, I might create a new layout with the smaller advertising space
and specify it as the layout for all controller's actions using
something like:
var $layout = 'default_small_ad';
Elements
Many applications have small blocks of presentational code that needs
to be repeated from page to page, sometimes in different places in the
layout. Cake can help you repeat parts of your website that need to be
reused. These reusable parts are called Elements. Ads, help boxes,
navigational controls, extra menus, and callouts are often implemented
in Cake as elements. An Element is basically a mini-view that can be
included in other Views.
Elements live in the /app/views/elements/ folder, and have the .thtml
filename extension.
The Element by default has no access to any data. To give it access to
data, you send it in as a named parameter in an array.
14. What does it

If you want your button to appear on all pages at the same place, then the easiest is to put the button as part of your layout.

Great place to start is the manual ! http://manual.cakephp.org/ Try and implement the 'blog' example - you will have a better understanding as to what goes where after that. Thanks, but it has so many undefined terms that I can't get very far. Could ANYONE just start by answering some simple questions? 1. What are the data structures that you enter into i.e. files that you create or software that you enter information into? 2. What are the outputs that it produces, on the screen or on paper? 3. How do you run the application after it has been programmed in CakPHP? How is it constructed?

Re: CakePHP programming problem
1. Create a button that will appear on all pages in the application at a particular location using CSS, and that does as follows. If you want your button to appear on all pages at the same place, then the easiest is to put the button as part of your layout. Your default layout goes in app/views/layout/default.thtml -- see this part of the manual to lear more about views and about layouts : http://manual.cakephp.org/chapter/views Once you've done this successfully, you might want to reconsider refactoring your button into an element -- but get it all running first ! 2. Read 2 fields CHOICE and FIND. a. The top one, CHOICE, is a drop-down list with the same 16 choices each time. Function ddlits() returns the list of 16 literal values that are displayed. b. The bottom one FIND is a text field with no default, so it is blank initially. 3. By special rules used only here, we translate (2) into a list of (Query#,SQL Query) pairs. Function qrz($choice,$find) = list of ($qnm,$sqry) pairs of Query# and Query. 4. Execute (3) and accumulate the results into []=(Query#,Tuple). That is, we have a function runsql($sqry) = list of tuples returned by query $sqry. 5. Translate (Query#,Tuple) => (Display,URL) by function qtdis($qnm,$tuple)=($display,$url) to create a list of links to display. 6. Display the (Display,URL) pairs as links. I'm not sure what you're trying to achieve - is this some sort of search functionality ? Have a look at this thread : http://groups-beta.google.com/group/cake-php/browse_thread/thread/671fe307f99c80c0/b447beb8fc71fe24?lnk=gst&q=search+form&rnum=1#b447beb8fc71fe24 it might help ! Can someone tell me how to implement this in CakePHP? Please be explicit: I have to write what and store it where and do what to get the button to appear on the existing pages?
