URL Parameters 2

[jsteiner87]

I am trying to set up an area on my page that will only display information if a URL Parameter is present.
What I have is a value that is pass thru the URL called nameplate_id and if there is a value I want to have part of my page displayed. I don't want to display part of the page if nameplate_id does not show up in the URL. How do I setup that If statement?

The parameter passed would be in the superglobal array $_GET.
Your if statement would check if there is a value in the GET array under they key 'nameplate_id'.

if (isset($_GET['nameplate_id']) AND !empty($_GET['nameplate_id']){
   /* whatever happens here... )*/
}

The second part of the condition here checks if there is a value in the GET parameter. Be aware that the value '0' (zero) would also return true.

html stuff...

When you get to the part of the page you want to display if there's a value for nameplate_id:
<?php
if ($_GET['nameplate_id']){
  display part of that page.
}
?>

rest of the html stuff...

Cheers!
