In URL

[shage]

If my url is http://www.yahoo.com/coupon=free/index.php how can i pull out the "free" for a if and else statement, i use htaccess to set the default url to coupon=none but have the options of free and half which indicates shipping prices. Looking to be able to make the shipping status to free on the site if coupon=free and so on.

Cant you just use:

<?php
if($_GET['coupon'] == 'free/index.php'){
    echo 'you have a free coupon';
}else{
    echo 'you do not have a free coupon';
}
?>

thank you didnt know if i could do that, again thank you

it dont work, i get a blank echo trying it that way

it didnt work because your url isnt calling any GET parameters you have to add a ? before coupon to make the next part , part of the $_GET['coupon'] variable.

that being said i created a solution for you

 

<?
$coupon = explode("/",$_SERVER['PHP_SELF']);
if ($coupon[1] == "coupon=free")
{
echo "you have a free coupon";
}
else
{
echo "You pay full price";
}
?>

good idea! problem is, if the coupon is ever set in a sub directory..

http://www.yahoo.com/subdir/coupon=free/index.php

 

in which case you could do an in_array:

<?php
$coupon = explode("/",$_SERVER['PHP_SELF']);
if(in_array('coupon=free', $coupon)){
echo "you have a free coupon";
}else{
echo "You pay full price";
}
?>

 

But either option is very unreliable. Mainly because if you're simply going by the coupon to check if it is free or not, you are opening yourself to attack. Someone could simple add 'coupon=free' into the url and get whatever it is for free.
