[SOLVED] Using variables

[alexiek]

Hello everybody, I'm new to PHP. My issue is, I can't seem to figure out how I can take data I received, put it into a variable and resend the data. Example:

I have a site and when a link is clicked it goes link.php?data=hello. Now, how I can I use the data and then resend it. link.php then refreshes itself and sends the data to the next site. So then it would go data.php?data=hello&referrer=link. And in following this, how can I make var $data have data that was sent using link.php. Get it? Thanks much.

<?php

$data = $_GET['data'];

echo "<a href='link.php?data=$data&referrer=4512'>link</a>";

?>

 

Then it just keeps continuing from there. To put "referrer into a variable you would just go $referrer = $_GET['referrer']...which would hold the value "4512" in this case.

 

$_GET is the method you use to grab values out of the URL.

Thank you so much.

 

Here is the next line of script that won't work for some reason.

 

<?php

$data = $_GET['LN'];

include ('detail.php?LN=$data'); ?>

 

It just sends $data as the text $data and when I try to move around the colon, i get a parse error.

you cant include files like that. try this:

 

<?php
$LN = $_GET['LN'];
include('detail.php');
?>

Use double quotes to parse variables inside an include function.

 

include("includedfile.php?something=$var")
