This is going to be really easy (php)

Just not for me, I've done it before, but I can't remember how, basically I have a form, with say 1 text field, I want that field populated by whatever is suffixed on the URL, e.g.

http://www.blah.com/test.php?price=12345

Then, the form field should populate with 12345.

Simple eh? Just not for a plank like me, any help is as always appreciated.

Thanks.

Ah, I've fixed it

it was echo $whatever

Someone can close this now :D

OK I'm bending the rules a little here but I'll just add that echo $something will work only if you have globals on.

The more usual (and secure) way is to use the following:

PHP Code:


		
			
<?php

/*

Let's say we have an URL like http://www.domain.com/index.php?something=value

To get this we need to use the HTTP GET array like so:

*/



$something = $_GET['something'];

echo $something;



// Or POST (if preceded by a method="post" in the HTML form tag)



$something = $_POST['something'];

echo $something;

?>

I'd do something like:

PHP Code:


		
			
<?php

$price = $_GET['price'];

echo "<input type=\"text\" name=\"price\" value=\"$price\" />";

?>
