Pass end of URL as $_GET variable to template file (5 posts)

    I'm sure this must be fairly simple but can't figure out how to do it.

    I have a page with it's own template, say mysite.com/custom. This page is handled by custom.php.

    How can I set it up so that mysite.com/custom/anything is handled by custom.php?var=anything

    I just need whatever comes after custom/ passing to custom.php as a string, no matter what it is.

    If say your trying to find a variable being passed to it

    http://yourdomain.tld/custom/?somevar=weirdo

    There are actually several different methods to do this, you can find and validate the $_REQUEST

    for example:

    if (isset($_REQUEST['somevar'])) $somevar = esc_attr($_REQUEST['somevar']);

    Or the WP prefered method where you check if the get_query_var has it.
    http://codex.wordpress.org/Function_Reference/get_query_var

    I just do this:

    if (isset($wp_query->query_vars['somevar'])) $somevar = esc_attr($wp_query->query_vars['somevar']);

    Thanks for your response. Sorry, I didn't explain what I meant properly.

    The problem is not for custom.php to find variables that have been passed to it. It's getting mysite.com/custom/any-random-stuff/with-slashes-etc to be handled by custom.php?var=any-random-stuff/with-slashes-etc

    Ah you need to create some rewrite rules to handle those

    http://codex.wordpress.org/Function_Reference/WP_Rewrite

    This allows you to create a new ruleset to use with custom permalinks

    Thanks again. I'm still a bit unclear on the usage of WP Rewrite. Do the functions there need to be run once, to update wordpress' rewrite rules? Where should they be run from?
