WordPress Metazoinks

A.K.A "Yet Another Meta Description Plugin." A WordPress plugin for editing the title and description <meta> tag for your public post types.

Filter the post types and/or add additional title and description inputs (eg. for sites with multiple languages):

// Filter metazoinks options.
add_filter( 'metazoinks_options', 'myprefix_filter_metazoinks_options' );

/**
 * Filter metazoinks options.
 *
 * @param array $options List of options.
 * @return array
 */
function myprefix_filter_metazoinks_options( $options ) {

    $options['post_types'] = array( 'post', 'my_cool_post_type' );

    $options['title_inputs][] = array(
        'label' => __( 'Title (French)', 'prefix' ),
        'meta_key' => '_meta_title_fr',
    );

    $options['description_inputs][] = array(
        'label' => __( 'Description (French)', 'prefix' ),
        'meta_key' => '_meta_title_fr',
    );

    return $options;
}

Do something with your additional inputs:

// Filter document title.
add_filter( 'metazoinks_title', 'myprefix_filter_metazoinks_title' );

/**
 * Filter document title.
 *
 * @param string $title Document title.
 * @return string
 */
function myprefix_filter_metazoinks_title( $title ) {

    // Assuming you have some sort of multilanguage setup, stuff like this might work.
    if ( 'fr_FR' === get_locale() ) {

        global $post;

        if ( ! empty( $post->_meta_title_fr ) ) {
            $title = esc_attr( $post->_meta_title_fr );
        }
    }

    return $title;
}
