Help Me Learn About Functions and Filters (7 posts)

    So I'm getting to the point where I should learn how to do some of this stuff myself instead of asking on forums every couple of days.

    I was hoping someone could show me an example using my current problem of how to make a filter (think that's what they're called) in my functions file. That way when I find some more stuff I want to 'filter' in the future I wont have to annoy you guys again ;)


    In a file named 'skematik-header-functions.php' I have this bit of code I want to filter out:

    bloginfo( 'name' );

    I thought I should be making some kind of filter in my functions.php file to filter out the code - but I could be wrong. Also I'm using a child theme so it won't be lost when I update. I've got the child theme thing sorted, just not sure how to make that filter.

    How would I do that?

    Am I approaching this thing all wrong? Would that be the best way to do it... search for a function, and then create a filter in my functions.php file?

    I have this bit of code I want to filter out:

    bloginfo( 'name' );

    can you post the code in its context?
    possibly just paste the full 'skematik-header-functions.php' into a pastebin and post the link to it here - http://codex.wordpress.org/Forum_Welcome#Posting_Code


    what do you actually want to achieve?

    what theme are you working with?

    Hey, thanks for the help.

    I'm working with the Skematik theme. I would as the developer - but support is very hard to come by.

    If I have WordPress SEO plugin active, my site has double site heading. It repeats the site name twice in all my page titles. So to fix that I removed the bloginfo( 'name' ); bit of code from my header by commenting it out (put // in front of it). And that code is found in the 'skematik-header-functions.php' file.

    But when I update my theme I loose that.

    I created a child theme to stop things like that happening. And I'm under the impression that I can make changes to my functions file in the child theme and it stays up to date even when I update the skematik frame work.

    So I want to know how to put something in my child theme functions file of how to 'filter' out that bit of code.

    Here is a pastebin of the entire skematik-header-functions.php file: http://pastebin.com/EUUgMR6g

    Sorry it's late here and I'm tired... hope that makes more sense.

    from that file:

    'remove_action' CALL.


    - for details you need to contact the theme's developers;

    commercial themes are not supported by this forum.

    I'm not a developer and don't entirely understand functions so the part I need help with is $tag and $function_to_remove (don't think I'll need $priority and $accepted_args right?).

    I've tried all different combinations in my functions file like:


    ...but none have worked.

    I'm trying to learn this better so I can apply it to other things later on without having to annoy you guys forum again and again ;)

    The support for the premium theme is very lacking so that's why I'm asking in here. Any help is very much appreciated.

    Could anyone show me what is the correct remove_action for this?
