開始使用
要建立簡單的聯繫表單，請將以下程式碼貼到您的 functions.php 文件中。並將 [contact] 簡碼貼到您的聯繫頁面。
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\Extension\Core\Type\EmailType;
use Symfony\Component\Form\Extension\Core\Type\TextareaType;
use Symfony\Component\Form\Extension\Core\Type\SubmitType;
class ContactForm {
/**
* 表單實體
*
* FormType
*/
private $form;
/**
* ContacForm 建構函式
*
* @return ContacForm
*/
public function __construct() {
$this->define_hooks();
}
/**
* 建立與處理聯繫表單
*
* 這個方法會在 WP 動作鉤執行。
* 它只會在擁有聯繫簡碼的頁面執行。
*
* @return void
*/
public function controller() {
global $post;
// 檢查是否為頁面且頁面內容有簡碼
if ( is_page() && has_shortcode( $post->post_content, 'contact' ) ) {
$factory = mf_get_factory();
// 建立表單
$this->form = $factory->create();
// 將欄位加入表單
$this->form->add( 'full_name', TextType::class );
$this->form->add( 'email', EmailType::class );
$this->form->add( 'message', TextareaType::class );
$this->form->add( 'submit', SubmitType::class );
// 取得請求物件
$request = mf_get_request();
// 處理請求
$this->form->handleRequest( $request );
// 檢查表單是否有效
if ( $this->form->isSubmitted() && $this->form->isValid() ) {
// 從表單取得資料
$data = $this->form->getData();
// 定義篩選器
$filters = array(
'full_name' => FILTER_SANITIZE_STRING,
'email' => FILTER_SANITIZE_STRING | FILTER_SANITIZE_EMAIL,
'message' => FILTER_SANITIZE_STRING,
);
// 欄位清洗
$sanitized_data = filter_var_array( $data, $filters );
// 處理表單資料的動作，例如發送電子郵件
// 以成功參數將使用者重新導向以防止重複提交表單
wp_safe_redirect( $this->get_redirect_url() );
}
}
}
/**
* 渲染聯繫表單。
*
* 這個方法會在聯繫簡碼執行。
*
* @return string
*/
public function render() {
$success = filter_input( INPUT_GET, 'success', FILTER_SANITIZE_NUMBER_INT );
if( '1' === $success ) {
return sprintf('<h2>%s</h2>', __('非常感謝您提交表單，我們將會盡快聯繫您。') ) ;
}
return $this->form->createView()->render();
}
}

Get started
To create simple contact form paste code bellow to your functions.php file. And paste [contact] shortcode to your contact page.
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\Extension\Core\Type\EmailType;
use Symfony\Component\Form\Extension\Core\Type\TextareaType;
use Symfony\Component\Form\Extension\Core\Type\SubmitType;
class ContactForm {
/**
* Form instance
*
* FormType
*/
private $form;
/**
* ContacForm constructor
*
* @return ContacForm
*/
public function __construct() {
$this->define_hooks();
}
/**
* Create and process contact form
*
* This method is executed by wp action hook.
* It will be executed only on page which has contact
* shortcode.
*
* @return void
*/
public function controller() {
global $post;
// Check if current view is page and page has content shortcode
if ( is_page() && has_shortcode( $post->post_content, 'contact' ) ) {
$factory = mf_get_factory();
// Create form
$this->form = $factory->create();
// Add fields to form
$this->form->add( 'full_name', TextType::class );
$this->form->add( 'email', EmailType::class );
$this->form->add( 'message', TextareaType::class );
$this->form->add( 'submit', SubmitType::class );
// Get request object
$request = mf_get_request();
// Handle request
$this->form->handleRequest( $request );
// Check if form is valid
if ( $this->form->isSubmitted() && $this->form->isValid() ) {
// Get data from the form
$data = $this->form->getData();
// Define filters
$filters = array(
'full_name' => FILTER_SANITIZE_STRING,
'email' => FILTER_SANITIZE_STRING | FILTER_SANITIZE_EMAIL,
'message' => FILTER_SANITIZE_STRING,
);
// Fields sanitization
$sanitized_data = filter_var_array( $data, $filters );
// Perform action with form data e.g. send an e-mail
// Redirect user with success parameter to prevent double submitting form
wp_safe_redirect( $this->get_redirect_url() );
}
}
}
/**
* Render contact form.
*
* This method is executed by contact shortcode.
*
* @return string
*/
public function render() {
$success = filter_input( INPUT_GET, 'success', FILTER_SANITIZE_NUMBER_INT );

}
$form_view = $this->form->createView();
$engine = mf_get_engine();
return $engine['form']->form( $form_view, array('attr' => array('novalidate' => 'novalidate') ) );
}
/**
* Method executed by constructor to define hooks and
* create and render contact form.
*
* @return void
*/
private function define_hooks() {
add_action( 'wp', array( $this, 'controller' ) );
add_shortcode( 'contact', array( $this, 'render' ) );
}
/**
* Build url for form redirect
*
* @return string
*/
private function get_redirect_url() {
$url = get_permalink();
$query = parse_url($url, PHP_URL_QUERY);
// Returns a string if the URL has parameters or NULL if not
if ($query) {
$url .= '&success=1';
} else {
$url .= '?success=1';
}
return $url;

// Initialize contact form
