Help with PHP Form?

[Zash]

So, I was wondering if anyone knew any answer on how to do this.

I am a PHP newbie, so go easy on me

Either way, I wanted to create a form so that when a user visits the URL http://example.com/form.php?variable=X

then, a form field assigned to the variable will be assigned the value 'X'.

PayPal uses this. I think it is like, HTTP requests, IDK.

Please help

Something like an action?
With the get method?

[pepotiger]

try this

PHP Code:

if(isset($_GET['variable'])
{
$var = urlencode($_GET['variable']);
} 


than put the $var variable in the form

If you want some resources for learning php then check out this thread: http://community.mybboard.net/thread-37709.html

But as pepotiger said the main thing you will need is the $_GET['whatever'] function which gets values from the url get data (what you want). The isset bit is just checking that the variable actually exists so that it doesn't spit any errors later in the program if it is not assigned.

Should be urldecode since you're getting a value from the URL. Also you need to use htmlspecialchars before outputting it into the HTML form.
