problem loading stylesheets to wp_head dynamically

Question

I'm trying to create a wrapper shortcut function to register and load stylesheets in the header. currently, the function loads this css file src:

http://my.test/wp-content/theme/css/.css

I, obviously want it to pass the parameter given. The problem is, the new function definition within the new function definition doesn't seem to be taking the parameter even though my #4th argument for add_action was 1 (parameter passable to function).

What am I doing wrong?? Please help :)

<?php //Registering stylesheets

load_stylesheet_like_a_boss('my-style.css');

function load_stylesheet_like_a_boss($filename){
    echo 'parent:'.$filename; //should return 'parent: my-style.css'
        add_action('wp_head', 'stylesheet_registration', 5, 1); 

        function stylesheet_registration($filename){
        echo ' / child:'.$filename.'<br>'; //should return ' / child: my-style.css'
        $name = str_replace('.css','', $filename);

        wp_register_style($name, get_bloginfo('template_directory').'/css/'.$name.'.css');
        wp_enqueue_style($name, 10);
    }
} ?>

Answer 1

While your code is a bit messy, I think the one thing that is breaking it is the wp_enqueue_style you've got there. The second parameter "10" just shouldn't be there.

Answer 2

I think you have a few problems:

1. The code is unnecessarily complex
2. You're passing the wrong arguments to wp_enqueue_style(). (You appear to be passing a priority, which this function does not accept.)
3. You're echoing inside of a callback that isn't intended to output anything
4. Conceptually, the idea of a wrapper for an enqueue action callback just doesn't seem to make sense.

Try something like this, instead:

<?php
function load_stylesheet_like_a_boss( $filename ) {

    if ( false == $filename ) {
        return;
    } else {

        function enqueue_stylesheet_like_a_boss( $filename ) {
            // Stylesheet handle
            // Returns all but the ".css" from $filename
            $handle = substr( $filename, 0, -4 );
            // Stylesheet path
            $path = get_template_directory_uri() . '/css/' . $filename;
            // Enqueue
            wp_enqueue_style( $handle, $path );
        }
        add_action( 'wp_enqueue_scripts', 'enqueue_stylesheet_like_a_boss' );

    }   
}
?>

Note: the load_stylesheet_like_a_boss() function must be called prior to the wp_head action firing. That means that it probably shouldn't be called in the template at all, but rather in functions.php, and hooked in somewhere - which causes me to wonder why you need such a wrapper at all?
