I have add custom fields in back office order for each line products :
My problem is that I don't know how to save this fields.
Can you please help me?
function cfwc_create_custom_field() {
$args = array(
'id' => 'custom_text_field_title',
'label' => __( 'Custom Text Field Title', 'cfwc' ),
'class' => 'cfwc-custom-field',
'desc_tip' => true,
'description' => __( 'Enter the title of your custom text field.', 'ctwc'
),
);
woocommerce_wp_text_input( $args );
}
add_action( 'woocommerce_before_order_itemmeta', 'cfwc_create_custom_field' );
我在每个行产品的后台订单中添加了自定义字段：
我的问题是我不知道如何保存这些字段 。
你能帮我吗？
function cfwc_create_custom_field（）{
$ args = array（
'id'= ＆gt;'custom_text_field_title'，
'label'=＆gt; __（'自定义文字字段标题'，'cfwc'），
'class'=＆gt;'cfwc-custom-field'，
'desc_tip'= ＆gt; true，
'描述'=＆gt; __（'输入自定义文本字段的标题。'，'ctwc'
），
）;
woocommerce_wp_text_input（$ args）;
}
add_action（ 'woocommerce_before_order_itemmeta'，'cfwc_create_custom_field'）;
To add and save a custom field to order "line items" in admin order edit pages you will use something like:
微信扫一扫// Add a custom field
add_action( 'woocommerce_before_order_itemmeta', 'add_order_item_custom_field', 10, 2 );
function add_order_item_custom_field( $item_id, $item ) {
// Targeting line items type only
if( $item->get_type() !== 'line_item' ) return;
woocommerce_wp_text_input( array(
'id' => 'cfield_oitem_'.$item_id,
'label' => __( 'Custom Text Field Title', 'cfwc' ),
'description' => __( 'Enter the title of your custom text field.', 'ctwc' ),
'desc_tip' => true,
'class' => 'woocommerce',
'value' => wc_get_order_item_meta( $item_id, '_custom_field' ),
) );
}
// Save the custom field value
add_action('save_post_shop_order', 'save_order_item_custom_field_value');
function save_order_item_custom_field_value( $post_id ){
if ( defined( 'DOING_AJAX' ) && DOING_AJAX )
return $post_id;
if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE )
return $post_id;
if ( ! current_user_can( 'edit_shop_order', $post_id ) )
return $post_id;
$order = wc_get_order( $post_id );
// Loop through order items
foreach ( $order->get_items() as $item_id => $item ) {
if( isset( $_POST['cfield_oitem_'.$item_id] ) ) {
wc_update_order_item_meta( $item_id, '_custom_field', sanitize_text_field( $_POST['cfield_oitem_'.$item_id] ) );
}
}
}
// Optionally Keep the new meta key/value as hidden in backend
add_filter( 'woocommerce_hidden_order_itemmeta', 'additional_hidden_order_itemmeta', 10, 1 );
function additional_hidden_order_itemmeta( $args ) {
$args[] = '_custom_field';
return $args;
}
Code goes in function.php file of your active child theme (or active theme). Tested and works.
