Validation idea

[Anon]

Hi all,

I was hoping to use header() to redirect the user on sucessful form validation but I'm not sure if the idea's valid.

I'm doing: -

if (isset($name)) {

header ('Location: blah.php');
exit;

} else {

echo("You must provide a name");
}

But I get: -

Warning: Cannot add header information - headers already sent by ....etc.

Can anyone please push me in the right direction?

TIA

Chris

This kind of error generated if ur trying to print/echo above the header() function .or incase u've left a blank line above the <?php Tag..or u might have added html tags..

I was aware of something like this - that's why I was wondering if it was even possible to do what I'm trying to do
🙂

In my code (which is in the middle of the program) I do this: -

if (isset($name)) {
header ('Location: blah.php');
exit;

There's no blank line before header, should I be able to use header like this? I.e. in the middle of my code as opposed to at the very top - if not I can't use it in an 'if' statement anyway and will need to re-think.

Shastry,

I figured it out now - I'd misunderstood what you said.

It was the html tags outside of the <? ?>

Thanks for your help.
