[SOLVED] Header redirect to previous page

[jdadwilson]

I have some php code that I want to reference from several pages.

 

I cannot put the code into a function since the calls are from action tags (which only refers to scripts).

 

Therefore, how does one use the Header function to return to the previous calling page?

I didn't understand what you told may be keep that code in my_code.php

and then include_once('my_code.php') in all the files

You can maybe use

header("Location: ".$_SERVER['HTTP_REFERER']);

to redirect to the last page?

header("Location: ".$_SERVER['HTTP_REFERER']);

to redirect to the last page?

Its not reliable

[neel_basu]

the page1.php will place a cookie page: page1.php (e.g. the last Page Name)

and the page2.php would follow the page thats in the Cookie

[BrandonE97]

The variable $_SERVER['HTTP_REFERER'] sets a cookie? What about the other $_SERVER variables?

No I am not talking about $_SERVER['HTTP_REFERER']

What I am telling is page1.php sets Cookie and page2.php reads to cookie to understand whats teh previous page.

OK, so for a newbie what is the code to do this?

The trigger to the code is from an anchor element. Using the href or the onclick both require a script. I would much like to put the code into a function in an include file and have it triggered by the anchor onclick event but I don't see how this can happen.

 

Any ideas...

include.php

<?php //this file is included in every page
function myFunction() {
   global $var1, $var2
   //do something
}
?>

 

your script that you will include the file into

<?php
include ('include.php'); //include your include file

if (!isset($_POST['submit'])) { //if the form has been submitted
  if ($_REQUEST['action'] == 'dosomething') { //if the form is asking to do something
    $dosomething = $_REQUEST['action']; //define the variable to be sent to the function
    myFunction($dosomething); //send your variable to your function to be done
  }
}
?>
