Basic Plugin Question

    OK, so I know I can write a plugin that has the code:

    add_filter(‘bloginfo’, ‘strtoupper’);

    and all the bloginfo content will be set to uppercase (blog title, description, etc).

    But how do I change something specific, for instance what if I wanted *only* the description from bloginfo to be uppercase?

    function toUpperBlogDescription($info, $show) {
    if ($show == 'blogdescription') {
    $info = strtoupper($info);
    }
    return $info;
    }

    add_filter('bloginfo', 'toUpperBlogDescription')

    Off the top of my head, something like that minus the error if any.

    This gives an error looking for the second argument for toUpperBlogDescription…

    I’m not sure if this code actually is doing what I am wanting to do, which is change the specific call to bloginfo(‘description’) rather than every instance of the bloginfo() function (which is built-in to PHP)

    function toUpperBlogDescription($info, $show) {
    if ($show == 'description') {
    $info = strtoupper($info);
    }
    return $info;
    }

    //add_filter('filter_name', 'filter_func', priority, number of arguments)
    add_filter('bloginfo', 'toUpperBlogDescription', 10, 2);

    The filter function toUpperBlogDescription is indeed invoked for every call to bloginfo; however, only if you retrieve the description then the output is converted to uppercase.

    Thanks! That did it. That last parameter when you call add_filter (the number of arguments) wasn’t shown on the wiki pages I was using… and it of course makes all the difference 🙂

    I’m going to fix/update the wiki pages when I go back.
