Question

我試圖添加一個文本字段，在他/她點擊「添加到卡片」按鈕之前，從產品頁面上的用戶接受文本值。以下是我在functions.php文件中添加的代碼：

function action_woocommerce_before_add_to_cart_button() 
{ 
    // make action magic happen here... 

    echo "<input type='text' name='engrave-text' id='engrave-text' placeholder='Your Engraving Text'>"; 
}; 

// add the action 
add_action('woocommerce_before_add_to_cart_button', 'action_woocommerce_before_add_to_cart_button', 10, 0); 
//Store the custom field 
add_filter('woocommerce_add_cart_item_data', 'add_cart_item_custom_data_vase', 10, 2); 
function add_cart_item_custom_data_vase($cart_item_meta, $product_id) { 
    global $woocommerce; 
    $cart_item_meta['test_field'] = $_POST['engrave-text']; 
    return $cart_item_meta; 
} 

//Get it from the session and add it to the cart variable 
function get_cart_items_from_session($item, $values, $key) { 
    if (array_key_exists('test_field', $values)) 
     $item[ 'Engraved-Text' ] = $values['test_field']; 
    return $item; 
} 
add_filter('woocommerce_get_cart_item_from_session', 'get_cart_items_from_session', 1, 3); 

但它不起作用。你能幫忙嗎？

謝謝

我想通了。以下代碼有效：

function action_woocommerce_before_add_to_cart_button() 
{ 
    // make action magic happen here... 

    echo "<input type='text' name='engrave-text' id='engrave-text' placeholder='Your Engraving Text'>"; 
}; 

// add the action 
add_action('woocommerce_before_add_to_cart_button', 'action_woocommerce_before_add_to_cart_button', 10, 0); 


function engrave_text_validation() { 
    if (empty($_REQUEST['engrave-text'])) { 
     wc_add_notice(__('Please enter a Name for Engraving', 'woocommerce'), 'error'); 
     return false; 
    } 
    return true; 
} 
add_action('woocommerce_add_to_cart_validation', 'engrave_text_validation', 10, 3); 


function save_engrave_text_field($cart_item_key, $product_id = null, $quantity= null, $variation_id= null, $variation= null) { 
    if(isset($_REQUEST['engrave-text'])) { 
     WC()->session->set($cart_item_key.'_engrave_text', $_REQUEST['engrave-text']); 
    } 
} 
add_action('woocommerce_add_to_cart', 'save_engrave_text_field', 1, 5); 

function render_meta_on_cart_item($title = null, $cart_item = null, $cart_item_key = null) {

     echo $title. '<dl class=""> 
       <dt class="">Engrave Text : </dt> 
       <dd class=""><p>'. WC()->session->get($cart_item_key.'_engrave_text') .'</p></dd>   
       </dl>'; 
    }else { 
     echo $title; 
    } 
}

     echo $quantity. '<dl class="">

     wc_add_order_item_meta($item_id, "Engrave Text", WC()->session->get($cart_item_key.'_engrave_text')); 
    } 
} 
add_action('woocommerce_add_order_item_meta', 'engrave_text_order_meta_handler', 1, 3); 

function engrave_force_individual_cart_items($cart_item_data, $product_id) 
{ 
    $unique_cart_item_key = md5(microtime().rand());

    return $cart_item_data; 
}
