I was wondering if theres another way to exit after validation!
where i put the ************* below i want to exit if it reaches that validation without finishing the include page but everytime i use exit function it exits continuing the home page text to display???
how can i exit just the include page????



example

Im using a page index.php for example


<?php
include 'test.php';
?>

<b> My Home page</b>


==============

<?php
//(test.php)

if ($variable ==123){
echo "123";
*************************************
}

if (isset($HTTP_SESSION_VARS['logged_user'])){
echo "user logged in";
}


?>

require your "include file" in stead of including it

see doc

Create it in functions and call it with the exit at the end (Function for HTML,Test). If you do not understand let me know and I will explain otherwise this should work

What are u talking about?

do you mean create a function and then use exit to exit from the function?

yes... or call a new function.

Do you want to just do one or the other? As in

if ($variable ==123){
echo "123";
} else {
if (isset($HTTP_SESSION_VARS['logged_user'])){
echo "user logged in";
}
}

When you are using exit it is stopping all processing when it hits the exit, meaning that it will not continue on with your home page.

is there just a way to exit just the include page only!

What do you mean by exit the include page? You mean you don't want to include the rest of it if the first test passes?

Comment from wtgee
Yes exactly i just want to validate the first test then exit if it fails!!!

Well, if you do the if...else statement I listed above it will accomplish the same thing. You don't really lose anything by loading the rest of the include file as long as it doesn't run (which the if....else statement prevents). If you really don't want it loaded you could do the if....else statement but put another include in the else instead of the code. That way if it never hits the else it will not load the rest of the text.

Like VGR said, don't do:

include('test.php');

but do a:

require('test.php');

instead.

If you want to stop parsing in the middle of an included file (you need include in this case), you can just enter return, like so:

return;

If you enter an

exit;

in a require'd page, the script will stop pasing completely.
(Haven't tested this, but that's what the docs say.)
