Question

我的插件中有一个动作处理程序，它捕获了一个发布到admin-ajax.php的表单。动作命名空间是＆＃39; handle_custom_form_submission＆＃39;。

我可以通过do_action（＆＃39; namespace＆＃39;，＆＃39; argument＆＃39;）函数轻松地将参数传递给我的动作处理程序。但是，如果我通过AJAX捕获一个动作，据我所知，我所能做的就是有一个$ _POST var，其名称=＆＃34; action＆＃34;和value =＆＃34; namespace＆＃34;。有没有办法以这种方式将参数传递给我的动作调用？喜欢

<input name="action" value="handle_custom_form_submission( 'a' )"/>

以下是更详细的情况：

我正在尝试编写自定义表单插件，以便我可以在Wordpress网站上轻松处理多个独特的表单。

在我的最新项目中，我在一个页面上有一个联系表格，在另一个页面上有一个推荐提交表格。在我的代码中，我只是将它们指定为＆＃39; custom-form-a＆＃39;和＆＃39; custom-form-b＆＃39;。

我有3个主要操作挂钩：

include_custom_form_js（$ form_id）
include_custom_form_html（$ form_id）
handle_custom_form_submission（）

我希望能够传递＃3，handle_custom_form_submission（），$ form_id。我现在唯一能想到的就是声明两个单独的函数，handle_custom_form_a_submission（）和handle_custom_form_b_submission（）。有更干净的方式吗？

我的主要插件文件：

<?php
/*
Plugin Name: Custom Form
Plugin URI: 
Description: Add custom form HTML and handle its submission on the backend.
Version: 0.1
Author: James Heston
*/

require_once( dirname( __FILE__ ) . '/php/constants.php' );

class CustomForm{

  // paths
  private $plugin_dir = CUSTOMFORM_DIRNAME;
  private $plugin_path = CUSTOMFORM_URLPATH;

  // action names
  private $action_include_js = 'include_custom_form_js';
  private $action_include_html = 'include_custom_form_html';
  private $action_handle_submission = 'handle_custom_form_submission';

  // other vars
  private $recipient_email = ''; // probably should pull from some WP option



  public function __construct(){
    $this->add_hooks();
  }

  private function add_hooks(){
    // include necessary js with appropriate MyAjax properties on page where `do_action( 'include_custom_form_js', $form_id )` action is called
    add_action( $this->action_include_js, array( $this, $this->action_include_js ), 10, 1 );
    // include form html on page where `do_action( 'include_custom_form_html', $form_id )` action is called
    add_action( $this->action_include_html, array( $this, $this->action_include_html ), 10, 1 );
    // handle contact form submission
    add_action( 'wp_ajax_' . $this->action_handle_submission, array( $this, $this->action_handle_submission ) );
    add_action( 'wp_ajax_nopriv_' . $this->action_handle_submission, array( $this, $this->action_handle_submission ) ); 
  }

  function include_custom_form_js( $form_id ){    

    wp_enqueue_script(
      $this->action_include_js,
      $this->plugin_path . '/js/custom-form-' . $form_id . '.js',
      array(),
      false,
      true
    );
    $localize_array = array(
      'ajaxurl' => admin_url( 'admin-ajax.php' ),
      'namespace' => $this->action_handle_submission
    );
    wp_localize_script( $this->action_include_js, 'MyAjax', $localize_array );
  }

  function include_custom_form_html( $form_id ){    
    include( $this->plugin_dir . '/html/custom-form-' . $form_id . '.html' );
  }  

  function handle_custom_form_submission(){
    $form_id = 'a';
    include( $this->plugin_dir . '/php/handle-custom-form-' . $form_id . 'submission.php' );
    include( $this->plugin_dir . '/php/handle-custom-form-' . $form_id . 'submission.php' );
  }

  function send_email(){
    // 
  }

  static function instance(){
    global $CustomForm;
    if(! isset($CustomForm) ){
      $CustomForm = new CustomForm();
    }
  }

}// class CustomForm

if(! isset($CustomForm) ){
  CustomForm::instance(); 
}
?>

通过$ _POST变量值将参数传递给Wordpress do_action函数
