How to use get_template_part passing params in WordPress

Have you ever needed a function that imports a template part but comes with a flag that indicates when that template should be rendered or not?

So do I. And when I started searching for a solution I found this awesome function. This way you can pass a Slider component for example, and mount it differently according the information is being passed on.

Place this code in your functions.php:

				
/**
 * Like get_template_part() put lets you pass args to the template file
 * Args are available in the tempalte as $template_args array
 * @param string filepart
 * @param mixed wp_args style argument list
 */
function hm_get_template_part( $file, $template_args = array(), $cache_args = array() ) {
    $template_args = wp_parse_args( $template_args );
    $cache_args = wp_parse_args( $cache_args );
    if ( $cache_args ) {
        foreach ( $template_args as $key => $value ) {
            if ( is_scalar( $value ) || is_array( $value ) ) {
                $cache_args[$key] = $value;
            } else if ( is_object( $value ) && method_exists( $value, 'get_id' ) ) {
                $cache_args[$key] = call_user_method( 'get_id', $value );
            }
        }
        if ( ( $cache = wp_cache_get( $file, serialize( $cache_args ) ) ) !== false ) {
            if ( ! empty( $template_args['return'] ) )
                return $cache;
            echo $cache;
            return;
        }
    }
    $file_handle = $file;
    do_action( 'start_operation', 'hm_template_part::' . $file_handle );
    if ( file_exists( get_stylesheet_directory() . '/' . $file . '.php' ) )
        $file = get_stylesheet_directory() . '/' . $file . '.php';
    elseif ( file_exists( get_template_directory() . '/' . $file . '.php' ) )
        $file = get_template_directory() . '/' . $file . '.php';
    ob_start();
    $return = require( $file );
    $data = ob_get_clean();
    do_action( 'end_operation', 'hm_template_part::' . $file_handle );
    if ( $cache_args ) {
        wp_cache_set( $file, $data, serialize( $cache_args ), 3600 );
    }
    if ( ! empty( $template_args['return'] ) )
        if ( $return === false )
            return false;
        else
            return $data;
    echo $data;
}

You can call this function in your page like this:

 hm_get_template_part( 'components/hero-video', [ 'video_number' => 1 ,'background' => 'ContactBG.png']); 

This way you can receive several other information that will tell the component how it should be rendered.

You can build a switch statament inside the template part that will handle the logic of displaying several versions for the same component, just by changing the params passed.
