在WooCommerce中，我正在开发一个从自定义帖子类型（CTP）中提取姓名和地址的插件。我想将它们加载到自定义结帐下拉字段中，我已经完成了所有工作。
但我需要做的是将来自CTP的信息加载到'options'数组中，如下所示：
我已经完成了大部分代码，我现在唯一的问题就是让它加载这个CPT中的所有帖子（有四个）。现在它只加载“请选择一些东西......”和一个帖子（最近的一个）。我的代码如下：
*修订代码*
add_filter( 'woocommerce_checkout_fields' , 'add_addressbook_checkout_field', 20, 1 );
function add_addressbook_checkout_field( $fields ) {
$options = array();
// First option
$options[0] = 'Please select something…';
// Get 'addressbook' posts
// $posts = array();
$args = array('post_type'=>'addressbook', 'posts_per_page'=>3000,'order'=>'asc');
$query = New WP_Query($args);
if($query->have_posts()):while($query->have_posts()):$query->the_post();
$temp = array();
$temp['id'] = get_the_id();
$temp['fname'] = get_field('fname');
$temp['lname'] = get_field('lname');
$temp['company'] = get_field('company');
$posts = $temp;
endwhile;endif;wp_reset_postdata();
// Loop through 'addressbook' posts (to set all other select options)
foreach( $posts as $post ){
// Set each complete name as an option (Where key is the post ID)
// $options[$posts['id']] = $posts['fname','id'] . ' ' . $posts['lname','id'] . ' ' . $posts['company','id'];
$options[$post->ID] = $posts['fname'] . ' ' . $posts['lname'] . ', ' . $posts['company'];
}
//, $post->ID
$fields['shipping']['addressbook'] = array(
'type' => 'select',
'label' => __('Address Book', 'woocommerce'),
'placeholder' => _x('Pick an address', 'placeholder', 'woocommerce'),
'options' => $options, // Here we set the options
'required' => false,
'priority' => 1,
'class' => array('form-row-wide'),
'clear' => true
);
return $fields;
}
我有填充select选项的地址列表，现在我只需要使用AJAX和查询结果填充表单的其余部分。代码如下： //广告'地址簿'自定义结帐选择字段
add_filter( 'woocommerce_checkout_fields' , add_addressbook_checkout_field', 20, 1 );
function add_addressbook_checkout_field( $fields ) {
$options = array();
// First option
$options[0] = 'Please select something…';
// Get 'addressbook' posts
$posts = array();
$args = array('post_type'=>'addressbook', 'posts_per_page'=>-1,'order'=>'asc');
$query = New WP_Query($args);
if($query->have_posts()):while($query->have_posts()):$query->the_post();
$temp = array();
$temp['id'] = get_the_id();
$temp['fname'] = get_field('fname');
$temp['lname'] = get_field('lname');
$temp['company'] = get_field('company');
$temp['addr1'] = get_field('address_line_1');
$temp['addr2'] = get_field('address_line_2');
$temp['city'] = get_field('city');
$temp['state'] = get_field('state');
$temp['zip'] = get_field('zip');
$posts = $temp;
$id = $posts['id'];
$fname = $posts['fname'];
$lname = $posts['lname'];
$company = $posts['company'];
$addr1 = $posts['addr1'];
$addr2 = $posts['addr2'];
$city = $posts['city'];
$state = $posts['state'];
$zip = $posts['zip'];
// Loop through 'addressbook' posts (to set all other select options)
foreach( $posts as $post ){
// Set each complete name as an option (Where key is the post ID)
$options[$id] = $company . ', '. $fname . ' '. $lname . ', ' . $addr1 . '....';
}
endwhile;endif;wp_reset_postdata();
$fields['shipping']['addressbook'] = array(
'type' => 'select',
'label' => __('Address Book', 'woocommerce'),
'placeholder' => _x('Pick an address', 'placeholder', 'woocommerce'),
'options' => $options, // Here we set the options
'required' => false,
'priority' => 1,
'class' => array('form-row-wide'),
'clear' => true
);
return $fields;
}
// process custom checkout field
add_action('woocommerce_checkout_process', 'check_addressbook_checkout_field', 20 );
function check_addressbook_checkout_field( $order, $data ) {
if ( isset($_POST['addressbook']) && empty($_POST['addressbook']) )
wc_add_notice( __("Please pick an address from the Address Book"),
'error' );
}
// Add custom meta data (or existing change data) to the order before saving
//it
add_action('woocommerce_checkout_create_order',
'set_meta_data_in_checkout_create_order', 20, 2 );
function set_meta_data_in_checkout_create_order( $order, $data ) {
if ( isset($_POST['addressbook']) ){
// Set the meta data in the order
if( ! empty($fname) )
$order->update_meta_data( 'ab_fname', esc_attr( $fname ) );
if( ! empty($lname) )
$order->update_meta_data( 'ab_lname', esc_attr( $lname ) );
if( ! empty($company) )
$order->update_meta_data( 'ab_company', esc_attr( $company ) );
if( ! empty($addr1) )
$order->update_meta_data( 'ab_addr1', esc_attr( $addr1 ) );
if( ! empty($addr2) )
$order->update_meta_data( 'ab_addr2', esc_attr( $addr2 ) );
if( ! empty($city) )
$order->update_meta_data( 'ab_city', esc_attr( $city ) );
if( ! empty($state) )
$order->update_meta_data( 'ab_state', esc_attr( $state ) );
if( ! empty($zip) )
$order->update_meta_data( 'ab_zip', esc_attr( $zip ) );
}
}

首先，不要使用ACF函数the_field()作为此函数echo的值，而应使用ACF函数get_field()代替在变量或某些PHP代码中设置值。
也无法在<option>中加载所有数据...您需要选择一些并将其包装为字符串...所以我选择了完整的名称作为与帖子相关的显示值ID选项键。然后使用该选项密钥（来自CTP的帖子ID），可以轻松检索相关数据......
然后是这样做的方法：
代码：
// Ad 'addressbook' custom checkout select field
add_filter( 'woocommerce_checkout_fields' , 'add_address_book_checkout_field', 20, 1 );
function add_address_book_checkout_field( $fields ) {
if ( ! is_ssl() ) return $fields; // if needed (?)
// Get 'addressbook' posts
$addressbook_posts = get_post(array('post_type'=>'addressbook', 'posts_per_page' => -1 ));
// First option
$options = array( '' => 'Please select something…');
// Loop through 'addressbook' posts (to set all other select options)
foreach( $addressbook_posts as $post ){
// Set each complete name as an option (Where key is the post ID)
$options[$post->ID] = get_field( 'fname', $post->ID ) . ' ' . get_field( 'lname', $post->ID );
}
$fields['shipping']['address_book'] = array(
'type' => 'select',
'label' => __('Address Book', 'woocommerce'),
'placeholder' => _x('Pick an address', 'placeholder', 'woocommerce'),
'options' => $options, // Here we set the options
'required' => false,
'priority' => 1,
'class' => array('form-row-wide'),
'clear' => true
);
return $fields;
}
// process custom checkout field
add_action('woocommerce_checkout_process', 'check_address_book_checkout_field', 20 );
function check_address_book_checkout_field( $order, $data ) {
if ( isset($_POST['address_book']) && empty($_POST['address_book']) )
wc_add_notice( __("Please pick an address from the Address Book"), 'error' );
}
// Add custom meta data (or existing change data) to the order before saving it
add_action('woocommerce_checkout_create_order', 'set_meta_data_in_checkout_create_order', 20, 2 );
function set_meta_data_in_checkout_create_order( $order, $data ) {
if ( isset($_POST['address_book']) ){
// The selected "Adress book" Post ID
$post_id = $_POST['address_book'];
// Get the data for the selected "Adress book" Post ID
$fname = get_field( 'fname', $post_id );
$lname = get_field( 'lname', $post_id );
$company = get_field( 'company', $post_id );
$addr1 = get_field( 'address_line_1', $post_id );
$addr2 = get_field( 'address_line_2', $post_id );
$city = get_field( 'city', $post_id );
$state = get_field( 'state', $post_id );
$zip = get_field( 'zip', $post_id );
// Set the meta data in the order
if( ! empty($fname) )
$order->update_meta_data( 'ab_fname', esc_attr( $fname ) );
if( ! empty($lname) )
$order->update_meta_data( 'ab_lname', esc_attr( $lname ) );
if( ! empty($company) )
$order->update_meta_data( 'ab_company', esc_attr( $company ) );
if( ! empty($addr1) )
$order->update_meta_data( 'ab_addr1', esc_attr( $addr1 ) );
if( ! empty($addr2) )
$order->update_meta_data( 'ab_addr2', esc_attr( $addr2 ) );
if( ! empty($city) )
$order->update_meta_data( 'ab_city', esc_attr( $city ) );
if( ! empty($state) )
$order->update_meta_data( 'ab_state', esc_attr( $state ) );
if( ! empty($zip) )
$order->update_meta_data( 'ab_zip', esc_attr( $zip ) );
}
}
代码放在活动子主题（或活动主题）的function.php文件中。它应该工作。
