.php?=

[freaksville]

Hey,

 

I'm a bit of a php n00b and was woundering if anyone could tell me how I can tell my php code to differ depending on what is at the end of the address.

 

(e.g. image.php and image.php?=blue)

 

The reason I want to know is that I have created a countdown to Christmas image (http://count.suprscribble.com/christmas/) and want people to be able to change the background colour depending on what extension of the address they use.

 

Thanks in Advance

Brad

You can get values from the query string using the $_GET superglobal.

 

somepage.php?var=something would be accessed like so:

 

echo $_GET['var']; // Something

http://count.superscribble.com/christmas/ <- correct link

 

I don't quite understand still. How can I use that to change the output, would I use an if function or something?

switch($_GET['var']) {
        case 'x':
        // if you have ?var=x then the code here will run
    break;

        case 'abc':
        // if you have ?var=abc then the code here will run
    break;

        default:
        // The default is not required, but code here will run if all of the above case statements aren't matched
        // (ie var isnt x or abc in this case
    break;
}

You could also do the same with an if elseif and else statement

if($_GET['var'] == 'x') {
    // if you have ?var=x then the code here will run
}elseif($_GET['var'] == 'abc') {
     // if you have ?var=abc then the code here will run
}else{
    // Same as default above
}

 

Hope that gives you some help
