[RESOLVED] Redirect in php problem ?

[TheStalker]

ok i know how to redirect within php using

header("Location: example.php);

and i know that you cant have any white space between the <?php ?> etc etc

So my question is really, If i have an if somewhere within my code like this

if(1==$eaxmple)
{
echo "YES!";
}
else
{
header("Location: example.php);
}

It wont work. Is there another redirect i should know about or is there a work round that im missing?

Thanks

That can still work, since if the IF condition fails then the echo will not be executed and the header() call will. (This assumes there is not other output before that IF condition.)

[TheStalker]

ok what if there is other output before? i have sql and other IFs before it

[TheStalker]

oh and aslo and include before as well

[NogDog]

Then you need to review your script's logic and structure so that you can ensure that no output is generated prior to your header() call. One tip, make sure any file you include/require prior to the header() does not generate inadvertent output by having any space/newlines after the include file's closing "?>" tag. In fact, you can just leave out the closing "?>" tag to make sure. (PHP will assume it is there if you leave it out.)

ok thanks for the advice. I guess its just a case of jiggling the code around a bit.

It's also a good case for separating the business logic from the output code (such as is done with templating systems or the vaunted Model View Controller design pattern).
