It sounds like you're saying this isn't possible, yet it is. So what am
I missing? Is there an error in my code?

Paul:
What I am saying is your form is a POST-method-form and it will only
send variables via the POST method. If you change the form's method
to GET, then the variables from the form will be sent via the GET
method.
Remember, there is ONLY ONE form being used per Submit action -- it
can either be a POST method or a GET method, but it can not be both.
This does not mean that you can't send both POST and GET variables
together via the same Submit action, but it does mean that the *form*
will only send it's contents via one method or the other.
Here's a demo:
http://php1.net/c/post-get
Please note that the POST method form will send only POST data and
the GET method form will send only GET data. However, you can force a
POST method *form* via the action attribute value to also include a
GET variable (see Submit POST w/GET) -- BUT -- that does not come
from the form's input but rather from the action attribute. Do you
see what I mean?
The code is shown.
Also, please note interaction between the GET/POST/REQUEST re the
variable 'alfa' and you will get an idea of why REQUEST may pose a
problem.
Cheers,
tedd

Dear All,
I am reading "PHP5 and MySQL Bible". Chapter 7 of the book says that PHP can

variables in GET and POST variable sets and that conflict resolution is done
by variable_order option in php.ini Can some one write a small program to
illustrate the previous ideas? It is not clear to me as to how to implement
this.
Many thanks,
Ashim.
Ashim:
What others have not addressed is that the form used to send
variables will send only GET OR POST method variables, but not both
at the same time.
Using REQUEST will show the values of the variables sent, but will
not show what method was used (not addressing COOKIE) and that is the
reason why it's not the best idea to use REQUEST.
Furthermore, as you point out, conflict resolution is done in
accordance with variable order as set in the php.ini file and that
can be different between different environments. As such, a script
can act differently and there in lies the problem.
Now, I have used scripts that may receive POST or GET variables and
act accordingly, but you will never (except possibly AJAX) have a
situation where a script will receive both sets of variables at the
same time. So, I don't think one can write a small simple script that
can demonstrate this.
This is terribly wrong... any drupal site (or probably any front
controller based CMS) will use GET variables to route to the correct
page which may have a form which will capture the POSTed data. I've
seen POST and GET often in the same page.
Cheers,
Rob.
Rob:
Understood, but that is not what I am addressing. A form can only
send data it has collected via it's declared method and the choices
are POST or GET, but not both.
Please review the post I made to Paul on this subject -- that
explains this concept better.
Cheers,
tedd

Understood. It sounded like you were saying you could only get back POST
or GET values from a page, which isn't true. The form itself, yes, can
only have one or the other method attribute.

This is why I don't use the REQUEST variable.

Hi!
I've been developing this stand alone application, found the webserver
that I am going to use (it is written in php) and all is good... on
windows.
I can get the php.exe and php-cgi.exe running no issue on windows
without "installing" them... even tested on 3 machines (developed on
Vista, sent to my friend on W7, and my GF on XP Home) and they all work
fine... now I was trying to port it over to linux, and I can't find
anything that I can use :(
Is there such a thing? or will I have to have a pre-req of "php and
php-cgi must be installed on linux" disclaimer?
Any help, or pointers to where my google-fu has failed me would be
appreciated :)
TIA!
Steve

I don't know if there's a web server under Linux which is written in
PHP. But I imagine you'd be hard pressed to find a Linux distribution
which does not come with several web servers and PHP either already
installed or easily installable. After all, most of the web is running
on Linux servers.

it's not that I dont want to have a webserver installed, it is a
standalone app, that doesn't require apache or any other httpd server
running... for people who want to run this on their windows, or linux,
or slackware servers and have no use for an "apache" server running for
just this.
i've got it working for windows, where i didn't have to install
anything, was just looking for something for a "*nix" distribution that
will do it too.
the webserver i am using, is 'nanserv', which works perfectly for what I
need it to do, and running under linux, it's very fast (windows is a bit
slow, but that's windows for ya)
I guess I am just going to have to say that having PHP installed is a
pre-req for the app (i just dont want to go installing software on
people's computers)

What you are looking for is php cli.
http://docs.php.net/manual/en/install.unix.commandline.php contains
scant information about this.
But, a common mechanism (and as a windows only user, I'm 50% guessing
here) in getting a "file" to run it's handler is to add a line to the
top of the file which the shell you are running uses to determine the
program responsible for handling it.
On Windows, this is a combination of the extension and the registry
(controlled by assoc and ftype). On *nix, the line at the top of the
script seems to to a similar thing.
#!/usr/bin/php
http://articles.sitepoint.com/article/php-command-line-1 seems like a
good place to start.
There may be some issue with the line. The install may be in a
different location or have a different name (#!/usr/local/bin/php-cgi
for example).

I have 2 buttons on a page:
if (isset($_POST['botton1'])) {dothing1();}
if (isset($_POST['button2'])) {dothing2();}
They both work as intended when I click on them. If however I click
within a text box and hit enter, they both fire.
Is there a way to stop this?
Thanks.

Check your code. My experience has been that forms with multiple submits
will fire the *first* submit in the form when you hit Enter in a text
field or whatever. I just tested this and found it to be true.
Now, I'm doing this in Firefox on Linux. I suppose there could be
differences among browsers, but I suspect that the specs for HTML
mandate the behavior I describe.

If you don't mind using a little JavaScript you can test for which button
should fire when enter is pressed. How I would do it is to first add a hidden
field and call it "buttonClicked". Now, in the text field where you would like
a button to fire if enter is pressed, at this to the tag:
onkeyup="checkKey(this,event)". For the JavaScript portion of it, do this:
function checkKey(element,evt) {
var buttonClicked=""
if(evt.keyCode=13) {
if(element.name="field1") {
buttonClicked="button1"
} else if(element.name=="field2") {
buttonClicked="button2"
}
if(buttonClicked) {
document.formName.buttonClicked.value=buttonClicked
document.formName.submit()
}
}
}
Hope that helps!
Take care,
Floyd

Yeah, but you don't even have to go that far. Just put a print_r($_POST)
at the beginning of the file, and you'll see which button gets pressed.
It will show up in the POST array.

this could also work;
JS:
function send ( selectedtype )
{
document.formname.postingvalue.value = selectedtype ;
document.formname.submit() ;
}
html:
<form name=formname>
<input type="hidden" name="postingvalue" />
<a href="javascript:send('1')">Button 1</a></td>
<a href="javascript:send('2')">Button 2</a></td>
<a href="javascript:send('3')">Button 3</a></td>
php:
if($_POST['postingvalue']=="1")
{ code here } elseif ($_POST['postingvalue']=="1")
{ code 2 here } bla bla

Hello.
in html:
<input type="submit" value="Update" name="op">
<input type="submit" value="Checkout" name="op">
in PHP
if(isset($_POST['op'])){
switch($_POST['op']){
case 'Update':
dothing1();
break;
case 'Checkout':
dothing2();
break;
default:
dohatehackersfunction(':)');
break;
}
}
PS: Don't use multiple input type="image" buttons - all IE's don't
send value attribute in POST - use CSS

Now I have a situation. I need to take the code from my former home
page and modify it to lay out a table (let's say 5 cells wide) and
as many rows deep to contain all the items. Each item is the name of
the directory, under which is an icon image from that directory,
under which is a description file read from that directory. Here is
my code thus far:
<?php
# The next several lines declare an array of directories which are
NOT to be listed!#
$excludes[] = 'attachments'; #20
$excludes[] = 'data';
$excludes[] = 'include';
$excludes[] = 'resources';
$excludes[] = 'stats';
$excludes[] = '_private';
$excludes[] = '_vti_bin';
$excludes[] = '_vti_cnf';
$excludes[] = '_vti_log';
$excludes[] = '_vti_pvt';
$excludes[] = '_vti_txt'; #30
$excludes[] = '_vxi_txt';
$excludes[] = 'css';
$excludes[] = 'img';
$excludes[] = 'images';
$excludes[] = 'js';

well, this ends the row after every cell. I am trying to get a row
of 5 cells across, then end it and start a new row. If the routines
stops before the end of the count of 5 due to lack of further
directories, closing out the table following the loops will onclude
a </tr> tag.

Hi everyone! I'm just starting out with PHP so I'm looking for a good
place to ask some questions, have my code critiqued (read: visciously
ripped apart), and generally BS about PHP and programming in general
(if that's OK). I know that PHP sometimes has a reputation for having
(some) lousy developers, and I'd like to avoid becoming one of those
people. To that end, I've subscribed here because I've always found
mailing lists to have much higher-quality discourse than the average
online foum.
Looking forward to participating!

P.S, The rules page on the web
(http://us2.php.net/reST/php-src/README.MAILINGLIST_RULES) is
currently broken, but this one works:
http://us2.php.net/reST/php-src/trunk_README.MAILINGLIST_RULES. Just a
heads up to whoever is in charge of that.

So I decided to write a template class in order to get myself going on
learning PHP. Of course I wrote the simplest thing possible:
class Template
{
protected $template;
protected $vars;
public function __construct($template)
{
$this->template = $template;
}
public function __set($name, $value)
{
$this->vars[$name] = $value;
}
public function __get($name)
{
return $this->vars[$name];
}
public function __toString()
{
ob_start();
eval('?>' . $this->template);
return ob_get_clean();
}
}
Which you can use, quite simply like this:
$tpl = new Template(file_get_contents('index.tpl.php'));
$tpl->title = 'Here\'s the title';
$tpl->text = 'Blah blah blah...';
echo $tpl;
I have a few questions though.
- First, I'm storing the template as an actual string, instead of just
a path to a template file, which means I'm using eval() instead of
require() in my __toString(). My thinking was that this would avoid
reading the template file twice in the case that __toString() gets
called multiple times. But will PHP handle this automagically if I do
in fact decide to store a path to a file, and call require() instead?
- Secondly, I noticed that in the constructor, it's not necessary to
initialize $vars to an empty array, and I haven't done so. I guess PHP
automatically initializes it the first time I set one of its elements
to a value. Is this okay, or is there a better way in the name of best
practices?
- Finally, I'd like to be able to limit what things can be accessed
from the scope of the template file. As it stands, if you have a
function named blowUpTheComputer() or a gobal variable called
$dontTouchThis, a template author can easily cause trouble. They can
also access any methods and properties of the Template class. How
would you go about restricting this?
Thanks a lot!

This is *not* a simple class. You're using magic methods, etc.

Advice: don't use eval() this way. It's slow and dangerous. I'd suggest
simply reading your template file into a class variable in the
constructor. Considering this is a "template" class, you're likely to
need to read the whole thing in at some point anyway. Do it at the
beginning and avoid eval() and the like. Also, you're not obligating
your user to read in the file and pass it to you on the stack, which is
really an abuse of the stack if you can avoid it. And once read in, you
can "vet" it with various PHP functions to ensure it doesn't have
dangerous content when it is eventually output.

PHP is a language which doesn't require variables to be initialized
before use. That said, it's probably superior programming practice to do
so anyway. That way, you *know* what's in there when you accidentally
use the variable later (which you will).

Now you see the liability of eval(). If you're going to allow
user-defined and evaluated functions in your template, you're going to
have to live with the consequences. Fortunately, the worst thing that's
liable to happen is they hose the website, not the whole computer; PHP
runs with the permissions of the server, which are generally limited to
hacking up files in the web root directories.
Rather than evaluating user functions at runtime, I would instead allow
"hooks", where the user can perhaps "register" a function and you
include() or require() its file later. Drupal uses a scheme vaguely like
this. Of course, you're still stuck if the user is an idiot or
malicious.
Actually, I'd consider a template class like this overkill anyway,
unless you plan to build a templating language and interpreter. Instead,
simply set a variable to the template filename, and just include() it at
some point. Make the user initialize all the variables and read in all
the include files before you do this. They can then do anything they
like within the template, which is generally just a HTML file with some
PHP code in it.
And if you're truly new to PHP, I'd suggest just coding some forms with
PHP to handle the interaction in them as a first action. This will get
you used to the way PHP handles variables, POST and GET, and the like.
Simple stuff without classes, until you're fully comfortable with basic
PHP variable handling, built-in functions, etc.
