遍历订单项时如何检查自定义复选框产品元的值 [英] How to check value of Custom Checkbox Product Meta when looping through order items

问题描述

我在Dokan new-single-product.php模板中创建了一个自定义复选框元:

I created a custom checkbox meta in Dokan new-single-product.php template:

<div class="dokan-form-group">
   <div class="dokan-input-group">
   <?php dokan_post_input_box( $post_id, '_custom_field', array( 'label' => __('Custom Checkbox','dokan') ), 'checkbox' ); ?>
  </div>

然后使用以下代码存储值:

Then used the following code to store the values:

add_action( 'woocommerce_product_options_general_product_data', 'wc_custom_add_custom_fields' );
function wc_custom_add_custom_fields() {
    global $woocommerce, $post;

   echo '<div class="options_group">';

  // Checkbox
    woocommerce_wp_checkbox( 
    array( 
        'id'            => '_custom_field',
        'label'         => __('Custom Field', 'woocommerce' )
        )
    );

  echo '</div>';
}

// Save Fields
add_action( 'dokan_process_product_meta', 'wc_custom_save_custom_fields' );
add_action( 'dokan_new_product_added', 'wc_custom_save_custom_fields' );
add_action( 'woocommerce_process_product_meta', 'wc_custom_save_custom_fields' );
function wc_custom_save_custom_fields($post_id) {

    $woocommerce_wccaf_precio_por_ = $_POST['_custom_field'];
    if( !empty( $woocommerce_wccaf_precio_por_) || empty( $woocommerce_wccaf_precio_por_))
        update_post_meta( $post_id, '_custom_field', esc_attr( $woocommerce_wccaf_precio_por_ ) );

}

现在，我希望逻辑是:遍历订购物料，如果物料已选中自定义复选框，则将物料行价格总计添加到$ amount变量中.这将在订单完成时运行.

Now I want the logic to be: Go through Order Items, IF item has custom checkbox checked, add item line price total to $amount variable. This runs on order complete.

public function amount_total( $order_id ) {

                // Get Order
                $order   = wc_get_order( $order_id );
                $amount = 0;

                // Loop through order items
                $items = $order->get_items(); 

                foreach ( $order->get_items() as $item_id => $item ) {
                    $custom_field = $item->get_meta('_custom_field');
                    //$custom_field = wc_get_order_item_meta( $item_id, '_custom_field', true );
                //  $custom_field = get_post_meta( $item_id, '_custom_field', true );
                    $line_total = $item->get_total();

                    if( isset($custom_field) ) {
                        $amount += $line_total;
                    }
                }

在尝试找到的每个解决方案时，我都有3个不同的$ custom_field变量.但是什么都没用.

I've got 3 different $custom_field variables as I've been trying every solution that I've found. But nothing's working.

如果我检查Dokan的产品编辑菜单中复选框上的元素，它将显示以下内容:屏幕截图

If I inspect element on the checkbox in the product edit menu for Dokan, it shows this: screenshot

似乎有2个输入，其中1个隐藏.也许我应该尝试检索已检查"属性，而不是实际值?

It seems there are 2 inputs, 1 hidden. Maybe I should be trying to retrieve the attribute 'checked' rather than the actual values?

推荐答案

关于这方面还有更多文章，我一直认为我的问题有所不同，但是我做了以下工作，并使用我在桌面上找到的一般解决方案进行了修复.其他帖子:

There are a couple more articles on this and I have been thinking my problem is different however I did the following and fixed it with the general solution I found on the other posts:

1. 检查了元密钥中实际上在数据库中存储了什么元值.

1. Checked what meta value is actually being stored in the database for the meta key.

检查过的get_post_meta方法的参数对方法是可读的(在我的情况下$ item_id无效，该方法需要产品的实际帖子ID)

Checked get_post_meta method's parameters are readable to the method (in my case $item_id was invalid, the method requires the actual post ID of the product)

检查条件是否实际上使用了正确的值:if($ custom_field =="yes")

Check the condition was actually using the right values: if( $custom_field == "yes" )

foreach函数的最终代码:

Final code for foreach function:

foreach ( $order->get_items() as $item_id => $item ) {
                $product_id = $item->get_product_id();
                $custom_field = get_post_meta( $product_id, '_custom_field', true );
                $line_total = $item->get_total();

                if( $custom_field == "yes" ) {
                    $amount += $line_total;
                }
            }
