创建包含专用部分的个性化 WooCommerce 设置页面

Question

我正在尝试将自定义设置选项卡添加到 WooCommerce 设置屏幕。基本上我想通过子部分/子选项卡实现与“产品设置”选项卡类似的功能：

我还没有找到任何关于如何执行此操作的像样文档，但我已经能够使用以下代码段添加自定义选项卡：

class WC_Settings_Tab_Demo {

    public static function init() {
        add_filter( 'woocommerce_settings_tabs_array', __CLASS__ . '::add_settings_tab', 50 );
    }

    public static function add_settings_tab( $settings_tabs ) {
        $settings_tabs['test'] = __( 'Settings Demo Tab', 'woocommerce-settings-tab-demo' );
        return $settings_tabs;
    }
}
WC_Settings_Tab_Demo::init();

根据我从各种线程/教程中挖掘出的内容，我一直在尝试将部分/子选项卡添加到新的设置选项卡中，如下所示：

// creating a new sub tab in API settings
add_filter( 'woocommerce_get_sections_test','add_subtab' );
function add_subtab( $sections ) {
    $sections['custom_settings'] = __( 'Custom Settings', 'woocommerce-custom-settings-tab' );
    $sections['more_settings'] = __( 'More Settings', 'woocommerce-custom-settings-tab' );
    return $sections;
}


// adding settings (HTML Form)
add_filter( 'woocommerce_get_settings_test', 'add_subtab_settings', 10, 2 );
function add_subtab_settings( $settings, $current_section ) {
    // $current_section = (isset($_GET['section']) && !empty($_GET['section']))? $_GET['section']:'';
    if ( $current_section == 'custom_settings' ) {
        $custom_settings = array();
        $custom_settings[] = array( 'name' => __( 'Custom Settings', 'text-domain' ),
                                   'type' => 'title',
                                   'desc' => __( 'The following options are used to ...', 'text-domain' ),
                                   'id' => 'custom_settings'
                                  );

        $custom_settings[] = array(
                                    'name'     => __( 'Field 1', 'text-domain' ),
                                    'id'       => 'field_one',
                                    'type'     => 'text',
                                    'default'  => get_option('field_one'),

                                );

        $custom_settings[] = array( 'type' => 'sectionend', 'id' => 'test-options' );
        return $custom_settings;
    } else {
        // If not, return the standard settings
        return $settings;
    }
}

我已经能够使用与上面类似的代码向“产品”选项卡添加新的小节，但它不适用于我的新自定义选项卡。我哪里出错了？

Answer 1

1) 要添加包含部分的设置选项卡，您可以首先使用 woocommerce_settings_tabs_array 过滤器挂钩：

// Add the tab to the tabs array
function filter_woocommerce_settings_tabs_array( $settings_tabs ) {
    $settings_tabs['my-custom-tab'] = __( 'My custom tab', 'woocommerce' );

    return $settings_tabs;
}
add_filter( 'woocommerce_settings_tabs_array', 'filter_woocommerce_settings_tabs_array', 99 );

2) 要向页面添加新部分，您可以使用 woocommerce_sections_{$current_tab} 复合挂钩，其中 {$current_tab}需要替换为第一个函数中设置的键 slug：

// Add new sections to the page
function action_woocommerce_sections_my_custom_tab() {
    global $current_section;

    $tab_id = 'my-custom-tab';

    // Must contain more than one section to display the links
    // Make first element's key empty ('')
    $sections = array(
        ''              => __( 'Overview', 'woocommerce' ),
        'my-section-1'  => __( 'My section 1', 'woocommerce' ),
        'my-section-2'  => __( 'My section 2', 'woocommerce' )
    );

    echo '
';

    $array_keys = array_keys( $sections );

    foreach ( $sections as $id => $label ) {
        echo '
' . $label . ' ' . ( end( $array_keys ) == $id ? '' : '|' ) . ' 
';
    }

    echo '

';
}
add_action( 'woocommerce_sections_my-custom-tab', 'action_woocommerce_sections_my_custom_tab', 10 );

3)为了添加设置以及处理/保存，我们将使用自定义函数，然后调用该函数：

// Settings function
function get_custom_settings() {
    global $current_section;

    $settings = array();

    if ( $current_section == 'my-section-1' ) {

        // My section 1
        $settings = array(

            // Title
            array(
                'title'     => __( 'Your title 1', 'woocommerce' ),
                'type'      => 'title',
                'id'        => 'custom_settings_1'
            ),

            // Text
            array(
                'title'     => __( 'Your title 1.1', 'text-domain' ),
                'type'      => 'text',
                'desc'      => __( 'Your description 1.1', 'woocommerce' ),
                'desc_tip'  => true,
                'id'        => 'custom_settings_1_text',
                'css'       => 'min-width:300px;'
            ),

            // Select
            array(
                'title'     => __( 'Your title 1.2', 'woocommerce' ),
                'desc'      => __( 'Your description 1.2', 'woocommerce' ),
                'id'        => 'custom_settings_1_select',
                'class'     => 'wc-enhanced-select',
                'css'       => 'min-width:300px;',
                'default'   => 'aa',
                'type'      => 'select',
                'options'   => array(
                    'aa'        => __( 'aa', 'woocommerce' ),
                    'bb'        => __( 'bb', 'woocommerce' ),
                    'cc'        => __( 'cc', 'woocommerce' ),
                    'dd'        => __( 'dd', 'woocommerce' ),
                ),
                'desc_tip' => true,
            ),

            // Section end
            array(
                'type'      => 'sectionend',
                'id'        => 'custom_settings_1'
            ),
        );
    
    } elseif ( $current_section == 'my-section-2' ) {

        // My section 2
        $settings = array(

            // Title
            array(
                'title'     => __( 'Your title 2', 'woocommerce' ),
                'type'      => 'title',
                'id'        => 'custom_settings_2'
            ),

            // Text
            array(
                'title'     => __( 'Your title 2.2', 'text-domain' ),
                'type'      => 'text',
                'desc'      => __( 'Your description 2.1', 'woocommerce' ),
                'desc_tip'  => true,
                'id'        => 'custom_settings_2_text',
                'css'       => 'min-width:300px;'
            ),

            // Section end
            array(
                'type'      => 'sectionend',
                'id'        => 'custom_settings_2'
            ),
        );
    
    } else {
        // Overview
        $settings = array(

            // Title
            array(
                'title'     => __( 'Overview', 'woocommerce' ),
                'type'      => 'title',
                'id'        => 'custom_settings_overview'
            ),

            // Section end
            array(
                'type'      => 'sectionend',
                'id'        => 'custom_settings_overview'
            ),
        );
    }

    return $settings;
}

3.1) 通过 woocommerce_settings_{$current_tab} 复合挂钩添加设置：

// Add settings
function action_woocommerce_settings_my_custom_tab() {
    // Call settings function
    $settings = get_custom_settings();

    WC_Admin_Settings::output_fields( $settings );  
}
add_action( 'woocommerce_settings_my-custom-tab', 'action_woocommerce_settings_my_custom_tab', 10 );

3.2) 通过 woocommerce_settings_save_{$current_tab} 复合挂钩处理/保存设置：

// Process/save the settings
function action_woocommerce_settings_save_my_custom_tab() {
    global $current_section;

    $tab_id = 'my-custom-tab';

    // Call settings function
    $settings = get_custom_settings();

    WC_Admin_Settings::save_fields( $settings );

    if ( $current_section ) {
        do_action( 'woocommerce_update_options_' . $tab_id . '_' . $current_section );
    }
}
add_action( 'woocommerce_settings_save_my-custom-tab', 'action_woocommerce_settings_save_my_custom_tab', 10 );
