IF

[canadabeeau]

Okay I have a page index.php which has an if statement basically like this: if $var == "" then redirect else do nothing

Now it redirects to loading.php

now my question is that how do I make a session variable remember this page so when the person goes to loading.php and it does its functions as required they can be redirected back to that page, I ask becuase this action will take place on all pages in my website so yeah....

and as always thanks in advance, and this time season greetings as well :-)

Well, you can do it a few different ways. 

 

Most important part about using sessions (that a lot of people forget) is you need to tell PHP that you're USING sessions   At the very very very beginning of your script.  I'm not 100% sure what your logic is, but something like this might get you started.

 

<?php
session_start();

$_SESSION['var'] = $var;

if($_SESSION['var'] == ""){
// redirect
}



?>

knew how to do the if part but not the remember the pages URL part

[nafetski]

Ohhhh ok

 

There is a PHP SERVER variable that you can check against, to see if they are coming from your index page.

 

$_SERVER['REQUEST_URI']

 

So...

if($_SERVER['REQUEST_URI'] == "index.php"){
// redirect logic
}

 

[canadabeeau]

	$loc = $_SERVER['REQUEST_URI'];
echo $loc;

 

If I run the above and echo it on the page that index.php redirected to it says $loc is the page I am on

[nafetski]

Oops, meant $_SERVER['HTTP_REFERER'];

[canadabeeau]

now it echo s nothing

[nafetski]

I guess I'm not 100% sure what you're trying to do.

 

http://php.net/manual/en/reserved.variables.server.php

 

Here are the variables that are available from the server.  See if any of those suit your fancy, or post a bit more code so I can know what you're trying to accomplish

[canadabeeau]

Okay index.php

<?php	if($_SESSION['clientmac'] == ""){
	header('location: clientmac.php');
};?>

 

clientmac.php

then does its job and then we have

<?php 	$loc = $_SERVER['HTTP_REFERER'];
echo $loc;?>

so it should echo index.php and later I can change the echo to a redirect

[teamatomic]

$path=$_SERVER['SCRIPT_FILENAME'];//give you the whole thing

basename($path);// give you the file name
