对于预订网站，我正在尝试创建一个功能，可以根据人数添加与会者列表。感谢 LoicTheAztec，我已经获得了一次预订的代码。那部分工作正常。
对于多个预订，我也需要相同的功能。我怎样才能做到这一点？
这是代码：
//* Add a new checkout field
add_filter( 'woocommerce_checkout_fields', 'ppp_filter_checkout_fields' );
function ppp_filter_checkout_fields($fields){
$fields['extra_fields'] = array(
'participant_details' => array(
'type' => 'participant_details',
'required' => false,
'label' => __( 'Participant Details' )
),
);
// Add a "persons" hidden input field
foreach( WC()->cart->get_cart() as $cart_item ) {
$persons = $cart_item['booking']['_persons'][0];
}
echo '<input type="hidden" name="persons" value="' . $persons . '">';
return $fields;
}
//* Add the field to the checkout
add_filter( 'woocommerce_form_field_participant_details', 'ppp_filter_checkout_field_group', 10, 4 );
function ppp_filter_checkout_field_group( $field, $key, $args, $value ){
$op_cart_count = WC()->cart->get_cart_contents_count();
$items = WC()->cart->get_cart();
foreach($items as $item) {
$person = $item['booking']['_persons'][0];
}
if ($person > 1) {
$html = '';
$html .= "<h3>Deelnemers</h3>";
for ( $i = 1; $i < $person; $i++) {
$counter = $i + 1;
$html .= "Deelnemer ". $counter . "<br>";
$html .= woocommerce_form_field( "participant_details[$i][full_name]", array(
"type" => "text",
"return" => true,
"value" => "",
"required" => true,
"label" => __( "Naam" )
)
);
$html .= woocommerce_form_field( "participant_details[$i][email_address]", array(
"type" => "email",
"return" => true,
"value" => "",
"required" => true,
"label" => __( "Emailadres" )
)
);
}
return $html;
}
}
//* display the extra field on the checkout form
add_action( 'woocommerce_checkout_after_customer_details' ,'ppp_extra_checkout_fields' );
function ppp_extra_checkout_fields(){
$checkout = WC()->checkout();
foreach ( $checkout->checkout_fields['extra_fields'] as $key => $field ) :
woocommerce_form_field( $key, $field, $checkout->get_value( $key ) );
endforeach;
}
//* Validate custom checkout fields
add_action( 'woocommerce_after_checkout_validation', 'ppp_checkout_field_participant_details_validation', 20, 2 );
function ppp_checkout_field_participant_details_validation( $data, $errors ){
if ( isset( $_POST['persons'] ) && $_POST['persons'] > 1 ){
for ( $i = 1, $j = 2; $i < esc_attr( $_POST['persons'] ); $i++, $j++ ) {
if ( empty( $_POST['participant_details'][$i]['full_name'] ) )
$errors->add( 'participant_'.$i.'_full_name', __( "Please fill in the participant $j full name" ), 'error' );
if ( empty( $_POST['participant_details'][$i]['email_address'] ) )
$errors->add( 'participant_'.$i.'_email_address', __( "Please fill in the participant $j email address" ), 'error' );
}
}
}
//* Sanitize our custom field
function ppp_custom_process_checkout_field_participant_details( $posted ){
$clean = array();
foreach( $posted as $participant ){
$details = ppp_custom_checkout_clean_participant_details( $participant );
if( ! empty( $details ) ){
$clean[] = $details;
}
}
return $clean;
}
add_filter( 'woocommerce_process_checkout_participant_details_field', 'ppp_custom_process_checkout_field_participant_details' );
//*
function ppp_custom_checkout_clean_participant_details( $participant = array() ){
$details = array();
if( isset( $participant["full_name"] ) ){
$details['full_name'] = sanitize_text_field( $participant["full_name"] );
}
if( isset( $participant["email_address"] ) ){
$details['email_address'] = sanitize_text_field( $participant["email_address"] );
}
return $details;
}
//* Update_post_meta
add_action( 'woocommerce_checkout_update_order_meta', 'ppp_custom_checkout_field_update_order_meta', 10, 2 );
function ppp_custom_checkout_field_update_order_meta( $order_id, $posted ){
if( ! empty( $posted["participant_details"] ) ){
update_post_meta( $order_id, "_participant_details", $posted["participant_details"] );
} else {
delete_post_meta( $order_id, "_participant_details" );
}
}
add_action( 'woocommerce_checkout_update_order_meta', 'ppp_custom_checkout_field_update_order_meta', 10, 2 );
