Re: [PHP] PHP Syntax Help - Check?

Hmm.  OK with the help below, I am closer.

The other fields on the page are getting passed via form fields that  
look like this:

input  type="text" value="<?php echo check('element9'); ?>"  
name="form[element9]" size="40" maxlength="255"
so I added:
input  type="text" value="<?php echo check('my_id'); ?>"  
name="form[my_id]" size="40" maxlength="255"


and formcheck.php has:

<?php
//start the session
session_start();

//array of fields in form. (In the format "field_name" => "field_label")
$form_fields = array(
"element0" => 'Your Name:',
"element1" => 'Your Email:',
"element4" => 'Item Number:',
.....
);
and I added:
"my_id" => 'My ID Is:',

And this works!
So when I am on mypage.php and I enter a value into the form field  
"my_id" it carries over and repopulates should the form fail validation.

But upon initial load of the page from my link of mypage.php?my_id=5  
(so I am not getting there via a form submit) how do I get the value  
into the form field?
