Question

我已经包含了meta_data，这是我添加到购物车中的每个产品的注释。我需要的是当我在购物车页面中时，可以随数量更改此注释，并且当我更新购物车时meta_data也将更新。

当我点击更新购物车时，我尝试使用此更新：

add_action( 'init', 'update_cart_action', 9);
function update_cart_action($args) {
    global $woocommerce;
    echo '<script>console.log("pass1");</script>';
     if ( ( ! empty( $_POST['update_cart'] )`enter code here` || ! empty( $_POST['proceed'] ) ) && wp_verify_nonce('cart')) {
        $cart_totals  = isset( $_POST['cart'] ) ? wp_unslash( $_POST['cart'] ) : '';
        if ( ! WC()->cart->is_empty() && is_array( $cart_totals ) ) {
          foreach ( WC()->cart->get_cart() as $cart_item_key => $values ) {
                if ( isset( $cart_totals[ $cart_item_key ]['product_special_notes_field'] ) ) {
                  echo '<script>console.log("pass2");</script>';
                  WC()->cart->cart_contents[ $cart_item_key ]['product_special_notes_field'] = $cart_totals[ $cart_item_key ]['product_special_notes_field'];
                }
            }
         }
     }
}

// this adds Url as meta in Order for item
add_action ('woocommerce_add_order_item_meta', 'add_item_meta', 10, 2);
function add_item_meta( $item_id, $values ) {
    woocommerce_add_order_item_meta( $item_id, 'Special Notes', $values['product_special_notes_field'] );
}

要添加到产品页面

/**
 * Add a custom text input field to the product page
 */
function sbm_add_text_field_cart() { 
  ?>
  <?php
    if(get_field("option_per_item", get_the_ID())){
  ?>
    <div class="div-button-kg-item">
    <button class="button-kg-item" type="button" onclick="changePerItem();">PER ITEM</button>
    </div>
 <?php
  }
  ?>

 <div class="product-special-notes-field-wrap">
 <label id="product_special_notes_field_label" for="product_special_notes_field"><?php _e( 'Special Notes', 'product-special-notes' ); ?></label>
 <textarea name='product_special_notes_field' id='product_special_notes_field' rows="4" 
 placeholder="PERSONALISE the order e.g. “3 pieces instead of Kgs”"></textarea>
 </div>
<?php }
add_action( 'woocommerce_before_add_to_cart_button', 'sbm_add_text_field_cart' );

添加到购物车

/**
 * Add custom cart item data
 */
function sbm_add_cart_item_data( $cart_item_data, $product_id, $variation_id ) {
  if( isset( $_POST['product_special_notes_field'] ) ) {
    if(empty($_POST['product_special_notes_field']) || $_POST['product_special_notes_field'] == ""){
      return;
    }
    $cart_item_data['product_special_notes_field'] = sanitize_text_field( $_POST['product_special_notes_field'] );
  }
  return $cart_item_data;
 }
 add_filter( 'woocommerce_add_cart_item_data', 'sbm_add_cart_item_data', 10, 3 );

在购物车中显示

 /**
 * Display custom item data in the cart
 */
function sbm_get_item_data( $item_data, $cart_item_data ) {
  if(is_cart()){
    return;
  }
  if( isset( $cart_item_data['product_special_notes_field'] ) ) {
  $item_data[] = array(
  'key' => __( 'Special Notes', 'product-special-notes' ),
  'value' => wc_clean( $cart_item_data['product_special_notes_field'] )
  );
  }
  return $item_data;
 }
 add_filter( 'woocommerce_get_item_data', 'sbm_get_item_data', 10, 2 );

 /**
 * Add custom meta to order
 */
function sbm_checkout_create_order_line_item( $item, $cart_item_key, $values, $order ) {
  if( isset( $values['product_special_notes_field'] ) ) {
  $item->add_meta_data(
  __( 'Special Notes', 'product-special-notes' ),
  $values['product_special_notes_field'],
  true
  );
  }
 }
 add_action( 'woocommerce_checkout_create_order_line_item', 'sbm_checkout_create_order_line_item', 10, 4 );

 /**
 * Add custom cart item data to emails
 */
function sbm_order_item_name( $product_name, $item ) {
  if( isset( $item['product_special_notes_field'] ) ) {
  $product_name .= sprintf(
  '<ul><li>%s: %s</li></ul>',
  __( 'Special Notes', 'product-special-notes' ),
  esc_html( $item['product_special_notes_field'] )
  );
  }
  return $product_name;
 }
 
 add_filter( 'woocommerce_order_item_name', 'sbm_order_item_name', 10, 2 );


/**
* Add Continue Shopping Button on Cart Page & Checkout page
* Add to theme functions.php file or Code Snippets plugin
*/
add_action( 'woocommerce_before_cart_table', 'woo_add_continue_shopping_button_to_cart' );
add_action( 'woocommerce_before_checkout_form', 'woo_add_continue_shopping_button_to_cart' );





// get from session your special notes variable and add it to item
add_filter('woocommerce_get_cart_item_from_session', 'cart_item_from_session', 99, 3);
function cart_item_from_session( $data, $values, $key ) {
    $data['product_special_notes_field'] = isset( $values['product_special_notes_field'] ) ? $values['product_special_notes_field'] : '';
    return $data;
}

谢谢
