我正在使用 woocommerce 插件...实际上这是我对 php 的怀疑。我正在使用一些自定义字段,所以我应该将这些自定义字段的值获取到我的电子邮件中。
当我使用一个自定义字段“我的字段”时,我正在为我的电子邮件获取价值,但我不了解如何将所有自定义字段的值获取到我的电子邮件..
以下是适用于单个自定义字段的代码:(来自这里https://gist.github.com/3905785
:)
/**
* Add the field to the checkout
**/
add_action('woocommerce_after_order_notes', 'my_custom_checkout_field');
function my_custom_checkout_field( $checkout ) {
echo '<div id="my_custom_checkout_field"><h3>'.__('My Field').'</h3>';
woocommerce_form_field( 'my_field_name', array(
'type' => 'checkbox',
'class' => array('my-field-class form-row-wide'),
'label' => __('Fill in this field'),
'placeholder' => __('Enter a number'),
), $checkout->get_value( 'my_field_name' ));
echo '</div>';
}
/**
* Update the order meta with field value
**/
add_action('woocommerce_checkout_update_order_meta', 'my_custom_checkout_field_update_order_meta');
function my_custom_checkout_field_update_order_meta( $order_id ) {
if ($_POST['my_field_name']) update_post_meta( $order_id, 'My Field', esc_attr($_POST['my_field_name']));
}
/**
* 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;
}
我为 2 个自定义字段尝试了下面的代码:(下面的代码没有将任何自定义字段值发送到我的邮件..)请告诉我我在下面的代码中做错了什么:
/**
* Add the field to the checkout
**/
add_action('woocommerce_after_order_notes', 'my_custom_checkout_field');
function my_custom_checkout_field( $checkout ) {
echo '<div id="my_custom_checkout_field"><h3>'.__('My Field').'</h3>';
woocommerce_form_field( 'my_field_name', array(
'type' => 'checkbox',
'class' => array('my-field-class form-row-wide'),
'label' => __('Fill in this field'),
'placeholder' => __('Enter a number'),
), $checkout->get_value( 'my_field_name' ));
echo '</div>';
echo '<div id="my_custom_checkout_field"><h3>'.__('Keywords').'</h3>';
woocommerce_form_field( 'keywords', array(
'type' => 'text',
'class' => array('my-field-class form-row-wide'),
'label' => __('Fill in this field'),
'placeholder' => __('Enter something'),
), $checkout->get_value( 'keywords' ));
echo '</div>';
}
/**
* Update the order meta with field value
**/
add_action('woocommerce_checkout_update_order_meta', 'my_custom_checkout_field_update_order_meta');
function my_custom_checkout_field_update_order_meta( $order_id ) {
if ($_POST['my_field_name']) update_post_meta( $order_id, 'My Field', esc_attr($_POST['my_field_name']));
if ($_POST['keywords']) update_post_meta( $order_id, 'Keywords', esc_attr($_POST['keywords']));
}
/**
* 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,Keywords';
return $keys;
}
