WooCommerce中存在一个显示错误,即在任何;“产品数据”;设置选项卡。试试看:
// Display a custom field in product admin pages
add_action( \'woocommerce_product_options_general_product_data\', \'add_product_custom_wysiwyg_field\' );
function add_product_custom_wysiwyg_field() {
    global $product_object;
    echo \'<div class="product_custom_field">
    <p>\' . __( "Mer information" ) . \'</p>
    <div style="padding:9px;">\';
    $content  = $product_object->get_meta( $meta_key );
    wp_editor( $content, \'_technical_specs\', [\'textarea_rows\' => 6] );
    echo \'</div></div>\';
}
 您将得到类似的结果(它会产生一些JS错误):

The best way is to add a custom metabox 相反,就像产品简短描述一样:

因此,您重新访问的代码将改为:
// Add custom Meta box to admin products pages
add_action( \'add_meta_boxes\', \'create_product_technical_specs_meta_box\' );
function create_product_technical_specs_meta_box() {
    add_meta_box(
        \'custom_product_meta_box\',
        __( \'Technical specs\', \'cmb\' ),
        \'add_custom_content_meta_box\',
        \'product\',
        \'normal\',
        \'default\'
    );
}
// Custom metabox content in admin product pages
function add_custom_content_meta_box( $post ){
    $product = wc_get_product($post->ID);
    $content = $product->get_meta( \'_technical_specs\' );
    echo \'<div class="product_technical_specs">\';
    wp_editor( $content, \'_technical_specs\', [\'textarea_rows\' => 10]);
    echo \'</div>\';
}
// Save WYSIWYG field value from product admin pages
add_action( \'woocommerce_admin_process_product_object\', \'save_product_custom_wysiwyg_field\', 10, 1 );
function save_product_custom_wysiwyg_field( $product ) {
    if (  isset( $_POST[\'_technical_specs\'] ) )
         $product->update_meta_data( \'_technical_specs\', wp_kses_post( $_POST[\'_technical_specs\'] ) );
}
// Add "technical specs" product tab
add_filter( \'woocommerce_product_tabs\', \'add_technical_specs_product_tab\', 10, 1 );
function add_technical_specs_product_tab( $tabs ) {
    $tabs[\'test_tab\'] = array(
        \'title\'         => __( \'Mer information\', \'woocommerce\' ),
        \'priority\'      => 50,
        \'callback\'      => \'display_technical_specs_product_tab_content\'
    );
    return $tabs;
}
// Display "technical specs" content tab
function display_technical_specs_product_tab_content() {
    global $product;
    echo \'<div class="wrapper-technical_specs">\' . $product->get_meta( \'_technical_specs\' ) . \'</div>\';
}
