Question

I have a situation like this.

<php>
<redirect the page >
<exit>

<javascript>
<redirect the page again>

I want to have javascript that basicall disables the PHP redirect. So if Javascript is enabled on the browser, the javascript redirect will work, if it disable, the PHP redirect will work. Should I just enclose the PHP code in span and make it invisible? Any ideas?

Addition ok this is not a simple redirect. the form authentication is rather odd. Register.php -> register_submit.php -> Was there an error -> yes go back to register.php (everything is javascript at this point). What I have added is PHP authentication as well so if I see javascript is not enabled, I take the user to register.php *after it does the regular checking of fields *.

PHP is a server-side technology. By the time Javascript even sees what’s happened, it’s too late.

Short answer, JS can’t intercept/block PHP (as long as PHP is being called first).

Order of events:

1. Client requests page
2. PHP executes and generates output of page
3. Browser receives output
4. Browser begins parsing what was sent by what PHP already spit out.
