Retrieving URL Variables

cbshell

Hello all....I have a question which I assume has a pretty simple answer...but I can't figure it out for the life of me. I have written an HTML form and I have the following code:

and I am assuming that when I click on the link on the it opens the .php file and sends the selection variable to it. However, I am unable to retrieve it in my .php file. Currently, I am using this code in the .php file:

$choice=$_GET['selection'];

I have also tried:

$choice=$_POST['selection']

does anyone have any idea what I have done wrong?

Please Help!!!

using $_GET is the right thing to do so there must be some other kind of problem. would you mind posting the code of the page that takes the query string variables?

Hi there,

try this...

 <a href="www.blahblah.com/script.php?selection=yes">

Then use

$choice= $_GET['selection'];

That Should work

Did you just type that in wrong?

<a href:"http://www.blahblah.php?selection=yes">

should be:

<a href="http://www.domainname.com/blahblah.php?selection=yes">

... with an equal sign, a domain name and then a php filename.

This should work be the one that works.

$choice=$_GET['selection'];

I made a bit of a mistake on my first post:

In my HTML file I have this code:

this is included in a form with method=get.

The PHP end uses GET to "catch" the variable...

print $_SERVER['QUERY_STRING'];

if(!isset($_SERVER['QUERY_STRING'])){
echo("Query String doesn't exist");
}

echo $_GET['selection'];

This prints nothing...I have NO idea what's wrong

well, its not necessary or possible to use a real hyperlink with a form...
and your link syntax is wrong:
<a href="http://www.blahblah.com/categorylist.php?selection=desktop>
should be
<a href="http://www.blahblah.com/categorylist.php?selection=desktop">link text</a>

so one file should be:

and categorylist.php should be

<?
print $_SERVER['QUERY_STRING'];

if(!isset($_SERVER['QUERY_STRING'])){
echo("Query String doesn't exist");
}

echo $_GET['selection'];
?>

no form or form method needed at all.

if instead you did want to use a form. you woud have to put
