request form problem

[scialom]

Hi,

I have this code:
$Chk = $HTTP_POST_VARS['chk'];

But if I send nothing I get an error message:
Undefined index: chk

I need it to the page to recall to itself.

I know that I can use $Chk = $chk,
but my IIS response an error for that code. What should I do?

Try:

if (isset($HTTP_POST_VARS)) { $Chk = $HTTP_POST_VARS['chk']; }

Sorry, But it is still not working and I get the same error message.

Try this routine.... Atleast as an error trap and it should show you what your vars are:

reset($HTTP_POST_VARS);

while (list($name, $value) = each($HTTP_POST_VARS)) {
     ${$name} = $value;

 // echo var name and values to screen for now		
 echo "$name = ${$name};<BR>"; 
}
