在Woocommerce中，我想拥有一个完整表单的自定义支付网关。并且该表格的答案显示在验证页面中（我认为这是英文的感谢页面）和后台办公室中的顺序。
我在PHP中创建这个并不够好，一切都靠我自己。但我学会了更好，试图了解代码是如何工作的。
所以我试着找到一些与我的问题相近的东西我找到了这个很好的答案： Add a custom payment gateway with additional radio buttons in Woocommerce
我的问题回答了90％。
我发现自己如何添加其他类型的表单元素，如文本，复选框......
/**
* Output the "payment type" radio buttons fields in checkout.
*/
public function payment_fields(){
if ( $description = $this->get_description() ) {
echo wpautop( wptexturize( $description ) );
}
/**echo '<style>#transaction_type_field label.radio { display:inline-block; margin:0 .8em 0 .4em}</style>';**/
$option_keys = array_keys($this->options);
woocommerce_form_field( 'transaction_type-1', array(
'type' => 'checkbox',
'class' => array('transaction_type form-row-wide'),
'label' => __('Espèces', $this->domain),
), reset( $option_keys ) );
woocommerce_form_field( 'transaction_type-2', array(
'type' => 'checkbox',
'class' => array('transaction_type form-row-wide'),
'label' => __('Tickets restaurants', $this->domain),
), reset( $option_keys ) );
woocommerce_form_field( 'transaction_type-3', array(
'type' => 'checkbox',
'class' => array('transaction_type form-row-wide'),
'label' => __('Chèques vacances', $this->domain),
), reset( $option_keys ) );
woocommerce_form_field( 'transaction_type-4', array(
'type' => 'radio',
'class' => array('transaction_type form-row-wide'),
'label' => __('Payment Information - Test', $this->domain),
'options' => $this->options,
), reset( $option_keys ) );
}
但我不明白如何“存储”答案并显示它。我尝试了第一个复选框，我尝试了这个：
/**
* Save the chosen payment type as order meta data.
*
* @param object $order
* @param array $data
*/
public function save_order_payment_type_meta_data( $order, $data ) {
if ( $data['payment_method'] === $this->id && isset($_POST['transaction_type-1']) )
$order->update_meta_data('_transaction_type', esc_attr($_POST['transaction_type-1']) );
}
但它没有用。我想我错过了一些我可能不明白的事情：
reset( $option_keys )
因此，如果您对我的问题有解决方案和解释，或者至少是一个线索，它将对我有很大帮助。
尝试以下替换代码函数（对于多个复选框）：
/**
* Output the "payment type" fields in checkout.
*/
public function payment_fields(){
if ( $description = $this->get_description() ) {
echo wpautop( wptexturize( $description ) );
}
woocommerce_form_field( 'transaction_type-1', array(
'type' => 'checkbox',
'class' => array('transaction_type form-row-wide'),
'label' => __('Espèces', $this->domain),
), '' );
woocommerce_form_field( 'transaction_type-2', array(
'type' => 'checkbox',
'class' => array('transaction_type form-row-wide'),
'label' => __('Tickets restaurants', $this->domain),
), '' );
woocommerce_form_field( 'transaction_type-3', array(
'type' => 'checkbox',
'class' => array('transaction_type form-row-wide'),
'label' => __('Chèques vacances', $this->domain),
), '' );
$option_keys = array_keys($this->options);
woocommerce_form_field( 'transaction_type-4', array(
'type' => 'radio',
'class' => array('transaction_type form-row-wide'),
'label' => __('Payment Information - Test', $this->domain),
'options' => $this->options,
), reset( $option_keys ) );
}
/**
* Save the chosen payment type as order meta data.
*
* @param object $order
* @param array $data
*/
public function save_order_payment_type_meta_data( $order, $data ) {
if ( $data['payment_method'] === $this->id ) {
$meta_value = array(); // Initializing
if ( isset($_POST['transaction_type-1']) ) {
$meta_value[1] = __('Espèces', $this->domain);
}
if ( isset($_POST['transaction_type-2']) ) {
$meta_value[2] = __('Tickets restaurants', $this->domain);
}
if ( isset($_POST['transaction_type-3']) ) {
$meta_value[3] = __('Chèques vacances', $this->domain);
}
// Save transaction type (from fields 1 to 3) as an array
if( sizeof($meta_value) > 0 ) {
$order->update_meta_data('_transaction_type', $meta_value );
}
// Save transaction type test (from fields 4) as a string
if ( isset($_POST['transaction_type-4']) ) {
$order->update_meta_data('_transaction_type_test', esc_attr($_POST['transaction_type-4']) );
}
}
}
/**
* Display the chosen payment type on order totals table
*
* @param array $total_rows
* @param WC_Order $order
* @param bool $tax_display
* @return array
*/
public function display_transaction_type_order_item_totals( $total_rows, $order, $tax_display ){
if( is_a( $order, 'WC_Order' ) && $order->get_meta('_transaction_type') ) {
$new_rows = []; // Initializing
$options = $this->options;
// Loop through order total lines
foreach( $total_rows as $total_key => $total_values ) {
$new_rows[$total_key] = $total_values;
if( $total_key === 'payment_method' ) {
// Get transaction type array
if( $meta_data = $order->get_meta('_transaction_type') ) {
$new_rows['payment_type'] = [
'label' => __("Transaction type", $this->domain) . ':',
'value' => implode(',', $meta_data),
];
}
}
}
$total_rows = $new_rows;
}
return $total_rows;
}
它应该更好地工作......
