redirecting to different page after having sent data

[boonamera]

basically i'm trying to do something like this:

index.php has:

if($category == 0)
{
          // GO to error.php
}

how would i go about making the page refresh to error.php?
So if i understood correctly i can't used  header because I have data above it.
Then i can't use meta because that needs to be in the header.

What's left?

you can use header(location: $url)
or something like that i dont remember the exact syntax... regardless of the fact that there is code above
however you cant have output any data
meaning
this will work
[code]
if($category == 0)
{
    header(location: http://www.yoursite.com/error.php);
}
[/code]

[code]
echo "blah";
if($category == 0)
{
    header(location: http://www.yoursite.com/error.php);
}

[/code]

the second will fail becasue something has been output to the browser.
make sense?

correct syntax:
[code]
header("Location: http://www.yoursite.com/error.php");
[/code]

you can echo a <meta> refresh anywhere on the page, and it will still be picked up.

if you've already sent headers you could try using the javascript location object:
window.location.href = "http://yoursite.com/error.php"

you could also try to include the error.php, if the border styles and formating is the same.  you could use something like if(condition){include("error.php";)}

i would also rename the file .inc, so that it easy to tell wht it is used for.

this is sometimes good for form validation, where you want to redisplay the form, the form would simply be in the inc file

thanks guys

I got 2 versions working: with the meta and with the include

I couldn't use header as i had outputted preivously.

I think the include method should do the trick but the only problem with it is that I would like the address to show http://domain.com/error
anyways of doing that?

Otherwise ill stick with the meta,

thx
