basic variable question

[knelson]

the scenario:

i'm passing variables via form to a query page. If someone leaves out some input, I want them redirected to the original page.

	if ((!$var1) || (!$var2))

		{
			     header("Location:original_page.php");		

			     exit;	
		}

This works, but should I want to add a variable to indicate a certain type of error...how would I set one that's available to the original page?

(register_globals being on is not a concern for me. I'm working on a tiny intranet.)

thanks very much.

I think you could do something like this ...

If(!$var1){
$errorcode = 1
}elseif(!$var2) {
$errorcode = 2
}

if ($errorcode) {

header("Locationriginal_page.php?errorcode=$errorcode");

exit;
}

This just make the original page check for the value of $errorcode and display a message accordingly. I havn't tested that, but I think it's an okay method.

very much for the reply. it seems to be working; it's not returning the correct message on the original page for errorcode 2 (it shows the message for #1), but i may have typed something incorrectly..

cheers.

This is how I would do:

<?php

if(empty($var1))
{ 
$errorcode = "1";
}
elseif(empty($var2))
{ 
$errorcode = "2";
}

if ($errorcode)
{ 
header("Location:original_page.php?errorcode=$errorcode"); 
exit; 
}

?>

In 'original_page.php':

<?php

if(isset($errorcode))
{
if($errorcode == "1")
{
echo "You must fill in field 1";
}
else if($errorcode == "2")
{
echo "You must fill in field 2";
}
}

?>

that's exactly what i did for the original page.

cheers
