WooCommerce Code Snippets

This post with WooCommerce code snippets is mostly for myself, but I also answer questions at the WooCommerce Community Boards periodically, and this list of snippets can be useful for answering those questions.

/**
 * Remove WooCommerce Updater Notice
 */
remove_action('admin_notices', 'woothemes_updater_notice');

/**
 * Code to fix HTTP Error on uploads
 */
add_filter( 'wp_image_editors', 'change_graphic_lib' );

function change_graphic_lib($array) {
return array( 'WP_Image_Editor_GD', 'WP_Image_Editor_Imagick' );
}

/************* DECLARE WOOCOMMERCE SUPPORT ***************/

add_action( 'after_setup_theme', 'woocommerce_support' );
function woocommerce_support() {
    add_theme_support( 'woocommerce' );
}

/***
 * Add notice to WooCommerce pages
 */
function my_update_notice() {
    echo '<div class="update-nag notice">';
        echo '<p>';
        _e( 'In order for Room View to work properly with your artwork, you must enter your artwork size as HEIGHT by WIDTH. For example if you have a painting that is 20cm tall and 40cm wide, you would select your size as 020 x 40 cm', 'anphira' );
        echo '</p>';
    echo '</div>';
