a quick question about html variables

maransekar

I never get around to find how this works, so i thought i will post this (silly) question to you (the experts). My question is:

I have seen some e-commerce websites passing values like this with the urls

www.sampleecommerce.com/index.html?varname=varvalue

I am just wondering how do they catch that variable name value in the next page which is index.html??

If it is possible to do this can someone please let me know how to do it.

Thanks for your help in advance

By using Mod_rewrite, the mentioned url is possible.

Firstly its not actually a HTML page its being sent to. More than likely the site is configured with .html to be parsed as what ever server side programming engine they have running.

Secondly using your example

<?php
echo (isset($_GET['varname']) ? "Your QueryString was: " . $_GET['varname'] : "Try: ht."".tp://".$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF']."?varname=something");
?>

Take the ."". in the ht and tp vB is trying to parse it as a URL

if your using an apache webserver and you have full control over said server, you just need to add the .html extension to this line (as i have done in this example).

AddType application/x-httpd-php .php .html

in you httpd.conf file. your server will then parse all .html files as though they where .php. its not really a recomended approuch though as it will put extra load on the server if your html files really are just plain html. no need to parse them as php.
