问题描述
我正在为woocommerce follogin开发自定义付款方式，这是我的代码：
I am developing a custom payment method for woocommerce follogin is my code :
class WC_Gateway_Custom extends WC_Payment_Gateway {
public $domain;
/**
* Constructor for the gateway.
*/
public function __construct() {
$this->domain = 'custom_payment';
$this->id = 'custom';
$this->icon = apply_filters('woocommerce_custom_gateway_icon', '');
$this->has_fields = false;
$this->method_title = __( 'Custom', $this->domain );
$this->method_description = __( 'Allows payments with custom gateway.', $this->domain );
// Load the settings.
$this->init_form_fields();
$this->init_settings();
// Define user set variables
$this->title = $this->get_option( 'title' );
$this->description = $this->get_option( 'description' );
$this->instructions = $this->get_option( 'instructions', $this->description );
$this->order_status = $this->get_option( 'order_status', 'completed' );
// Actions
add_action( 'woocommerce_update_options_payment_gateways_' . $this->id, array( $this, 'process_admin_options' ) );
add_action( 'woocommerce_thankyou_custom', array( $this, 'thankyou_page' ) );
// Customer Emails
add_action( 'woocommerce_email_before_order_table', array( $this, 'email_instructions' ), 10, 3 );
}
/**
* Initialise Gateway Settings Form Fields.
*/
public function init_form_fields() {
$this->form_fields = array(
'enabled' => array(
'title' => __( 'Enable/Disable', $this->domain ),
'type' => 'checkbox',
'label' => __( 'Enable Custom Payment', $this->domain ),
'default' => 'yes'
),
'title' => array(
'title' => __( 'Title', $this->domain ),
'type' => 'text',
'description' => __( 'This controls the title which the user sees during checkout.', $this->domain ),
'default' => __( 'Custom Payment', $this->domain ),
'desc_tip' => true,
),
'order_status' => array(
'title' => __( 'Order Status', $this->domain ),
'type' => 'select',
'class' => 'wc-enhanced-select',
'description' => __( 'Choose whether status you wish after checkout.', $this->domain ),
'default' => 'wc-completed',
'desc_tip' => true,
'options' => wc_get_order_statuses()
),
'description' => array(
'title' => __( 'Description', $this->domain ),
'type' => 'textarea',
'description' => __( 'Payment method description that the customer will see on your checkout.', $this->domain ),
'default' => __('Payment Information', $this->domain),
'desc_tip' => true,
),
'instructions' => array(
'title' => __( 'Instructions', $this->domain ),
'type' => 'textarea',
'description' => __( 'Instructions that will be added to the thank you page and emails.', $this->domain ),
'default' => '',
'desc_tip' => true,
),
);
}
/**
* Output for the order received page.
*/
public function thankyou_page() {
if ( $this->instructions )
echo wpautop( wptexturize( $this->instructions ) );
}
/**
* Add content to the WC emails.
*
* @access public
* @param WC_Order $order
* @param bool $sent_to_admin
* @param bool $plain_text
*/
public function payment_fields(){
if ( $description = $this->get_description() ) {
echo wpautop( wptexturize( $description ) );
}
echo 'added custom field in radio buttons';
/**
* Process the payment and return the result.
*
* @param int $order_id
* @return array
*/
}
public function generate_form($order_id){
global $woocommerce;
// Get this Order's information so that we know
// who to charge and how much
$customer_order = new WC_Order($order_id);
$_instructions = $this->instructions;
$_order_status = $this->order_status;
$items = $customer_order->get_items();
$product_name = array();
foreach ( $items as $item ) {
array_push($product_name, $item['name']);
}
$_Description = implode(", ", $product_name);
echo 'here i want to get the value selected by the customer from front end';
//here is the part where i want to get the value of form inside payment_fields() fucntion
exit;
}
}
我需要设置交易类型我的自定义付款方式还附有屏幕快照，以便更好地理解，请参阅：
i need to set transaction type of my custom payment method attaching screen shot as well for better understanding, see:
如何使用该payment_fields（）函数没有帮助，我可以打印html，但不知道如何获取值并将其设置为订单的交易类型
there is no help on how to over ride this payment_fields() function i can get the html printed but don't have any idea how to get the value and set it as transaction type of the order
推荐答案
您的代码中存在一些错误，错误和遗漏的东西……这是一个完整的插件文件，可以在此特殊文件中添加在结帐页面中选中网关上的付款单选按钮。
There is some errors, mistakes and missing things in your code… Here is a complete plugin file that works adding to this "Special" payment radio buttons on the gateway when it's selected in checkout page.
自我选中的交易类型单选按钮值将按顺序保存为自定义元数据。
The selected "Transaction type" radio button value will be saved in the order as custom meta data.
所选的交易类型值将显示在以下位置：
The selected "Transaction type" value will be displayed in:
- 订单收到的页面，我的帐户>查看订单
- 管理员编辑订单页面
- 关于电子邮件通知
在订单查看页面上：
这是完整的插件代码：
