Re: [PHP] PHP Syntax Help - Check?

OK... external function... that would explain why I could not locate it.

Let me get right to the problem I am having with this code as someone  
may be able to help directly.

I have a link on a page that opens a contact form.  The link is  
mypage.php?my_id=5

So on mypage.php, I capture this value with:
$my_id=$_GET['my_id'];

I understand this much.  But when the end user submits this contact  
form they do so to formcheck.php and if formcheck.php sees a required  
field is blank, it throws it back to mypage.php with an alert.  BUT, I  
lose the value of the variable $my_id.  SO, I created a hidden field  
on mypate.php with  value="<?php echo $my_id; ?>" and on  
formcheck.php, I added $my_id = $_Post['my_id'];

However, when formcheck.php returns me to mypage.php, $my_id is still  
blank.

Very frustrating.

Any help determining what I am doing wrong is greatly appreciated.

Thanks.
