php – 后端订单列出Woocommerce 3.3中的自定义操作按钮

从WooCommerce版本3.3开始,下面的代码在管理员顺序列表中显示自定义操作按钮,不再起作用.

// Add your custom order action button
add_action( 'woocommerce_admin_order_actions_end', 'add_custom_order_actions_button', 100, 1 );
function add_custom_order_actions_button( $order ) {

    // Get the tracking number
    $traking_number = get_post_meta( $order->get_id(), '_aftership_tracking_number', true );
    if( empty($traking_number) ) return;

    // Prepare the button data
    $url    = esc_url('https://track.aftership.com/'.$traking_number.'?');
    $name   = esc_attr( __('Tracking', 'woocommerce' ) );
    $action = esc_attr( 'view tracking' ); // keep "view" class for a clean button CSS

    // Set the action button
    printf( '<a class="button tips %s" href="%s" data-tip="%s" target="_blank">%s</a>', $action, $url, $name, $name );
}

// The icon of your action button (CSS)
add_action( 'admin_head', 'add_custom_order_actions_button_css' );
function add_custom_order_actions_button_css() {
    echo '<style>.view.tracking::after { font-family: woocommerce; content: "\e005" !important; }</style>';
}

他们改变了什么来防止它在新版本中工作？
如何在Woocommerce 3.3版中使其工作？

解决方法:

以下是使其正常工作的正确方法,因为这是代码from one of my answers,它将在单独的浏览器窗口(或选项卡)中加载相应的跟踪页面.

hook 07001. What has changed in vesion 3.3+ is the function that displays the buttons wc_render_action_buttons() and so the displayed buttons html structure and classes too.
Why? … Because that order list display has been enhanced in version 3.3+.

编码：

// Add your custom order action button
add_action( 'woocommerce_admin_order_actions_end', 'add_custom_order_actions_button', 100, 1 );
function add_custom_order_actions_button( $order ) {

    // Get the tracking number
    $traking_number = get_post_meta( $order->get_id(), '_aftership_tracking_number', true );
    if( empty($traking_number) ) return;

    // Prepare the button data
    $url    = esc_url('https://track.aftership.com/'.$traking_number.'?');
    $name   = esc_attr( __('Tracking', 'woocommerce' ) );
    $class  = esc_attr( 'tracking' );

    // Custom action button (with a target='_blank' opening a new browser window)
    printf( '<a class="button wc-action-button wc-action-button-%s %s" href="%s" title="%s" target="_blank">%s</a>', $class, $class, $url, $name, $name );
}

// The icon of your action button (CSS)
add_action( 'admin_head', 'add_custom_order_actions_button_css' );
function add_custom_order_actions_button_css() {
    echo '<style>.wc-action-button-tracking::after { font-family: woocommerce !important; content: "\e01a" !important; }</style>';
}

代码位于活动子主题(或主题)的function.PHP文件中.

经过测试,仅适用于woocommerce 3.3版

Here I don’t use woocommerce_admin_order_actions usual action hook, but instead I use an unusual hook, to allow displaying the tracking page in a separate browser window (or tab)
