函数get_date_label_keys()。{ 添加“操作”(在“添加到购物车”按钮前添加“WooCommerce”),“显示自定义”字段,20); echo'<div id=“日期”>'; echo'</div><br clear=“all”>'; //添加到购物车字段验证(如果需要) $通过=错误; 返回$通过; 添加_filter(“WooCommerce”添加_cart_item_data“,”amp_添加_cart_item_data“,20,2); //循环遍历每个自定义字段 } //在购物车和签出页面上显示购物车项目中的日期 foreach(get_date_label_keys()as$key=>$label){ )(二) } }

代码位于活动子主题(或活动主题)的function.php文件中。测试和工作。

购物车项目

我已经在数组的第一个函数中设置了两个日期字段slug和标签。然后在其他地方调用这个函数,并使用foreach循环处理每个字段。这样可以避免重复、优化和压缩代码。

// Utility function that contain the 2 field keys and labels pairs used on all other functions
function get_date_label_keys(){
    $text_domain   = 'woocommerce';
    return array( 'est_delivery' => __( 'Estimated Delivery Date', $text_domain ),
                  'est_pickup'   => __( 'Estimated Pickup Date', $text_domain ) );
}

// Display custom fields on single product page (hook replaced)
add_action( 'woocommerce_before_add_to_cart_button', 'amp_display_custom_fields', 20 );
function amp_display_custom_fields(){
    echo '<div id="dates">';
    // Loop through each custom field 
    foreach( get_date_label_keys() as $key => $label ){
        $class = str_replace('est_', '', $key); // The class
        $value = isset($_POST[$key]) ? sanitize_text_field($_POST[$key]) : ''; // Display the value
        printf( '<div class="%s"><label>%s:</label> <input type="date" name="%s" value="%s" required /></div>', $class, $label, $key, $value );
    }
    echo '</div><br clear="all">';
}

// Add to cart fields validation (in case of need)
add_filter( 'woocommerce_add_to_cart_validation', 'amp_add_to_cart_validation', 20, 3 );
function amp_add_to_cart_validation( $passed, $product_id, $qty ){
    // Loop through each custom field 
    foreach( get_date_label_keys() as $key => $label ){
        if( isset( $_POST[$key] ) && empty( $_POST[$key] ) ){
            wc_add_notice( sprintf( __( '%s cannot be added to the cart until you enter a delivery date.', $domain ), get_the_title() ), 'error' );
            $passed = false;
        }
    }
    return $passed;
