Re: PHP Syntax Help - Check?

if you do the redirection with header('Location: /mypage.php'), setting a variable on formcheck.php is not enough. if you modify the header('Location: /mypage.php') to.. header('Location: /mypage.php?my_id=5') it will take the variable to mypage.php as $_GET['my_id] you can not expect a variable value set in to $_POST array to reflect on a totally different page without making it a form post (aka use of proper headers). i guess, it's time to you to read about session_start() method and the array $_SESSION available in php :) ~viraj On Thu, Feb 25, 2010 at 11:22 AM, Rick Dwyer <rpdwyer@earthlink.net> wrote: > 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. > > > >  --Rick > > > On Feb 25, 2010, at 12:31 AM, Paul M Foster wrote: > >> On Thu, Feb 25, 2010 at 12:16:08AM -0500, Robert Cummings wrote: >> >>> Rick Dwyer wrote: >>>> >>>> Hello all. >>>> >>>> I'm trying to learn PHP on the fly and I have a line of code that >>>> contains syntax I can't find documented anywhere: >>>> >>>> php echo check('element8'); >>>> >>>> In the above line, can someone tell me what "check" means? >>> >>> >>> In the above, check is a function.
