>我已经为woocommerce产品添加了一个自定义字段,它与以下代码配合得很好。但我的问题是如何将其添加到cart_item_data
// Display Text in Admin Panel
add_action('woocommerce_product_options_general_product_data', 'product_custom_text_field');
function product_custom_text_field()
{
// Custom Product Text Field ( para Tex Area -> woocommerce_wp_textarea_input )
woocommerce_wp_text_input(
array(
'id' => '_optional_text_field',
'label' => __('Customize title', 'woocommerce'),
'placeholder' => '',
'desc_tip' => 'true',
'description' => __('Customizable title for the field that the user must fill out.', 'woocommerce')
)
);
}
保存字段
add_action('woocommerce_process_product_meta', 'product_custom_text_field_save');
function product_custom_text_field_save($post_id)
{
if (!empty($_POST['_optional_text_field'])) {
update_post_meta($post_id, '_optional_text_field', esc_attr($_POST['_optional_text_field']));
}
}
Display The Text in Product Page
add_action('woocommerce_single_variation', 'display_text_field');
function display_text_field()
{
global $post;
if (get_post_meta($post->ID, '_optional_text_field', true)) {
echo "<div class='titulo-c'><label>";
echo get_post_meta($post->ID, '_optional_text_field', true);
echo "</label></div>";
return;
}
echo __('FREE LOCAL SHIPPING', 'woocommerce');
}
到目前为止,它可以正常工作,现在我想将其添加到 cart_item_data
,使用以下代码,但它对我不起作用。
add_filter( 'woocommerce_add_cart_item_data', 'add_cart_item_data', 25, 2 );
function add_cart_item_data( $cart_item_meta, $product_id ) {
$custom_data = array() ;
$custom_data[ "_optional_text_field"] = isset( $_POST['_optional_text_field'] ) ? sanitize_text_field ( $_POST['_optional_text_field'] ) : "" ;
$cart_item_meta ['custom_data'] = $custom_data ;
return $cart_item_meta;
}
在购物车和结帐页面上显示自定义数据。
add_filter( 'woocommerce_get_item_data', 'get_item_data' , 25, 2 );
function get_item_data ( $other_data, $cart_item ) {
if ( isset( $cart_item [ 'custom_data' ] ) ) {
$custom_data = $cart_item [ 'custom_data' ];
$other_data[] = array( 'name' => 'Title',
'display' => $custom_data['_optional_text_field'] );
}
return $other_data;
}
结果,在我看来:Title: ________
我将不胜感激任何使我的代码工作的建议。
对代码进行以下更改,如下所示,这应该可以工作。
/**
* Add data to cart item
*/
add_filter( 'woocommerce_add_cart_item_data', 'add_cart_item_data', 25, 2 );
function add_cart_item_data( $cart_item_meta, $product_id ) {
global $woocommerce;
$mytitle_form_data = get_post_meta($product_id, '_optional_text_field', true);
$custom_data = array() ;
$custom_data[ "_optional_text_field"] = $mytitle_form_data;
$cart_item_meta ['custom_data'] = $custom_data ;
return $cart_item_meta;
}
