Using custom url parameters in a page

Question

Im trying to create a custom image galleri that retrieves images from posts as can be seen here

http://kurdaktuellt.se/galleri/

problem in hand is that I'm trying to make the url somewhat user friendly and I've searched the internet for an answer and the closest thing I've come up with is

add_action( 'init', 'wpse12065_init' );
function wpse12065_init()
{
    global $wp;
    $wp->add_query_var('images');

    add_rewrite_rule(
        '^galleri/images/([^/]*)/?',
        'index.php?pagename=galleri&images=$matches[1]',
        'top'
    );

}

This url works just fine

http://kurdaktuellt.se/?pagename=galleri&images=1452

but this one

http://kurdaktuellt.se/galleri/images/1598/

shows nothing

Any help is very much appreciated Regards

Answer 1

My initial thought without being able to do further testing is that your custom galleri page is looking for the URL parameters in order to determine which post to pull images from. However, since you're rewriting the URL, those URL parameters don't technically exist (I could be wrong about this - I'm not at a spot where I can do testing and I don't know your exact code).

If your goal is to have user friendly URLs, you could go with a different approach than URL parameters. You could get the value of the $_SERVER["REQUEST_URI"] variable, split it on the "/" and determine the post from there.

[EDIT]

<?php
$currentUrl = $_SERVER["REQUEST_URI"];
$arrUrlParts = explode( "/" , $currentUrl );

#Assuming that your URL is "http://kurdaktuellt.se/galleri/images/1598/", the variables would end up looking like this:

# $currentUrl contains "/galleri/images/1598/"
# $arrUrlParts[0] contains ""
# $arrUrlParts[1] contains "galleri"
# $arrUrlParts[2] contains "images"
# $arrUrlParts[3] contains "1598"
?>

In the case above, $arrUrlParts[3] would contain the number that you're looking for.
