[Resolved] Parameter not passed

Bbsmiffy

I'm trying to update my existing and working site. So I've copied it to my laptop, setup Apache 2 with php 4, and installed mysql (just a little daunting for me but). The laptop site runs to a point. one of the php scripts generates a page with a link to another php script. Page displays ok but next script looses the params passed. viewauction.php?id=68 so when viewauction.php sees id it is blank (used echo to display). Help!!!!

It's on your own machine, yes? Did you edit php.ini and set register_globals=on (default is off).

You can't assume it is on if you distribute a script, as many hosts now disable for security reasons, and php5 it is hard coded off.

You need to read the variables in from the $_GET array otherwise, like:

foreach (array_keys($GET) as $key)
{
$$key = $GET[$key];
// print "GET variable $key is ${$key}<br />";
}

The commented line you can use to debug, otherwise delete it.

If there is only one variable it might be easier to just do this:
viewauction.php?id=68

$id = $_GET['id'];

this will work to. Good luck

It's a simple matter of having the PHP directive/setting register_globals off, when you assume it is on. For $id to automagically be created, it must be on, but, it's much preferred to have it off (default is off as of PHP 4.2.0). Here's an appropriate manual page:

http://www.php.net/variables.external

Read about register_globals, autoglobals, and predefined variables. Not sure what ClevaTreva meant by it being hard coded off in PHP5 but that's not true as the directive will continue to exist.

Thanks for the ideas I'll try them out.
register_globals were off and yes it's my own machine.

Thanks also for the link to the manual
