Woocommerce自定义字段不保存

Question

我在woocommerce中有3个自定义字段:

物质参考号,发票号和处理案件的请求者(代码接下来,如果你不想看到它只是向下滚动,它不重要)

add_action('woocommerce_after_order_notes', 'matter_reference_number_func');

function matter_reference_number_func( $checkout ) {

    echo '<div id="matter_ref"><h3>'.__('Matter reference number').'</h3>';

    woocommerce_form_field( 'matter_reference_number', array(
        'type'          => 'text',
        'class'         => array('my-field-class form-row-wide'),
        'placeholder'       => __('Matter reference number'),
        ), $checkout->get_value( 'matter_ref_num' ));

    echo '</div>';

}

add_action('woocommerce_after_order_notes', 'invoice_number_func');

function invoice_number_func( $checkout ) {

    echo '<div id="inv_num"><h3>'.__('Invoice number').'</h3>';

    woocommerce_form_field( 'invoice_number', array(
        'type'          => 'text',
        'class'         => array('my-field-class form-row-wide'),
        'placeholder'       => __('Invoice number'),
        ), $checkout->get_value( 'invoice_num' ));

    echo '</div>';

}

add_action('woocommerce_after_order_notes', 'sol_deal_func');

function sol_deal_func( $checkout ) {

    echo '<div id="sol_deal"><h3>'.__('Solicitor dealing with matter').'</h3>';

    woocommerce_form_field( 'matter_reference_number', array(
        'type'          => 'text',
        'class'         => array('my-field-class form-row-wide'),
        'placeholder'       => __('Solicitor dealing with matter'),
        ), $checkout->get_value( 'sol_deal' ));

    echo '</div>';

}

现在,当我尝试保存这些值时,它们不会出现在客户端和管理员的电子邮件中,甚至也不会出现在确认页面上.根据文件,这应该足以做到这一点; 但它不是.

/**
 * Update the order meta with field value
 **/
add_action('woocommerce_checkout_update_order_meta', 'matter_ref_num_checkout_field_update_order_meta');

function matter_ref_num_checkout_field_update_order_meta( $order_id ) {
    if ($_POST['matter_ref_num']) update_post_meta( $order_id, 'Matter Reference Number', esc_attr($_POST['matter_ref_num']));
}

/**
 * Update the order meta with field value
 **/
add_action('woocommerce_checkout_update_order_meta', 'invoice_num_checkout_field_update_order_meta');

function invoice_num_checkout_field_update_order_meta( $order_id ) {
    if ($_POST['invoice_num']) update_post_meta( $order_id, 'Invoice Number', esc_attr($_POST['invoice_num']));
}

/**
 * Update the order meta with field value
 **/
add_action('woocommerce_checkout_update_order_meta', 'sol_deal_checkout_field_update_order_meta');

function sol_deal_checkout_field_update_order_meta( $order_id ) {
    if ($_POST['sol_deal']) update_post_meta( $order_id, 'Solicitor Dealing With Matter', esc_attr($_POST['sol_deal']));
}

Answer 1

您正在使用钩子来更新post meta(作为订单ID的帖子ID).如果您检查数据库,您应该能够在相应的post id meta下看到这些字段.

如果你想将它们添加到电子邮件中,你还需要使用另一个钩子:

woocommerce_email_order_meta_keys

以下是woocommerce文档的参考:

/**
 * Add the field to order emails
 **/
add_filter('woocommerce_email_order_meta_keys', 'my_custom_checkout_field_order_meta_keys');

function my_custom_checkout_field_order_meta_keys( $keys ) {
    $keys[] = 'My Field';
    return $keys;
}

你真的只需要为每个动作使用一个钩子并将你的代码放在那里,例如:

/**
 * Update the order meta with field value
 **/
add_action('woocommerce_checkout_update_order_meta', 'custom_checkout_field_update_order_meta');

function custom_checkout_field_update_order_meta( $order_id ) {
    if ($_POST['matter_ref_num']) update_post_meta( $order_id, 'Matter Reference Number', esc_attr($_POST['matter_ref_num']));
    if ($_POST['invoice_num']) update_post_meta( $order_id, 'Invoice Number', esc_attr($_POST['invoice_num']));
    if ($_POST['sol_deal']) update_post_meta( $order_id, 'Solicitor Dealing With Matter', esc_attr($_POST['sol_deal']));
}

希望这可以帮助.
