$_GET variables from url

Copy linkTweet thisAlerts:
Jun 06.2010

I’m having an issue that I can’t seem to resolve.

In test.php I have:

[code=php]<a href=”results.php?id=$id”>Click</a>[/code]

Then I click the link to results.php with the following code.

[code=php]
$var = $_GET[‘id’];
[/code]

However, $var is empty. Can someone tell me what I’m doing wrong?

@NogDogJun 06.2010 — When you view the first file in the browser, what does the actual link look like when you do a "view source"? Perhaps $id does not have a value?

@quark76authorJun 06.2010 — Sorry about that. The first file has the variable set.

[code=php]
id = "1";

...

<a href="results.php?id=$id">Click</a>
[/code]

@NogDogJun 06.2010 — Is that a typo here, or did you forget the "$" at the start of the $id in the assignment statement? And what is the actual code being used to create the link? (I.e.: you need a PHP echo or print() statement to output the $id.)

Success!
