在WordPress內點擊創建新用戶

Question

因此，我試圖在WordPress中創建一個插件，在電子郵件通過驗證後，將作爲訂戶添加一個新用戶到數據庫。

我有我的插件文件夾，我們稱之爲'插件'。

在那裏，我們有index.php文件看起來像這樣：

<?php 


/** 
* Set up a PHP function to handle the AJAX request. 
**/ 

    add_action('wp_ajax_nopriv_add_subscriber','add_subscriber'); 
    add_action('wp_ajax_add_subscriber','add_subscriber'); 

/** 
* Initialize widgets 
**/ 

    add_action('widgets_init', 'more_subscribers_init'); 

/** 
* Register widget 
**/ 

    function more_subscribers_init() { 
     register_widget(more_subscribers); 
    } 

/** 
* Create the widget class 
*/ 
class more_subscribers extends WP_Widget { 

    function more_subscribers() { 
     $widget_options = array(
      'classname' => 'ms_class', 
      'description' => 'Shows a field where the user can enter email address' 
     ); 

     $this->WP_Widget('ms_id', 'More Subscribers', $widget_options); 
    } 

    /** 
    * Show widget form in Appearance/Widgets 
    */ 

    function form($instance){ 
     $ms_email = array('title' => 'Your email address'); 
     $instance = wp_parse_args((array) $instance, $defaults); 

     $title = esc_attr($instance['title']); 

     echo '<p>Title <input type="text" class="widefat" name="'.$this->get_field_name('title').'" value="'.$title.'" /></p>'; 
    } 

    /** 
    * Save the widget 
    */ 

    function update ($new_instance, $old_instance){ 
     $instance = $old_instance; 
     $instance['title'] = strip_tags($new_instance['title']); 
     return $instance;   
    } 

    /** 
    * Show widget in post/page 
    */ 

    function widget ($args, $instance){ 
     extract($args); 
     $title = apply_filters('widget_title', $instance['title']); 

     echo $before_widget; 
     echo $before_title.$title.$after_title; 

     echo '<input type="email" name="FirstName" placeholder="Your email address" id="input_fld">'; 
     echo '<input type="Submit" name="submit_email" value="Submit" id="submit_btn">';   

     //print widget 
     echo $after_widget; 
    } 

} 


?> 

然後我們有位於插件/ JS/

//Random function to test if jQuery is working 
$(document).ready(function() { 
    //$('aside#ms_id-2 h2').hide(); 

//email validate function 
function isValidEmailAddress(emailAddress) { 
    var pattern = new RegExp(/^(("[\w-\s]+")|([\w-]+(?:\.[\w-]+)*)|("[\w-\s]+")([\w-]+(?:\.[\w-]+)*))(@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$)|(@\[?((25[0-5]\.|2[0-4][0-9]\.|1[0-9]{2}\.|[0-9]{1,2}\.))((25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})\.){2}(25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})\]?$)/i); 
    return pattern.test(emailAddress); 
} 

//Execute a php script on click event using an ajax request 

    $('#submit_btn').click(function(){ 
     var entered = $('#ms_id-2 > input#input_fld').val(); 
     if (isValidEmailAddress(entered) == false) { 
      alert('Sorry, the email you entered is invalid. Please try again.'); 
     } else { 
      ajaxData = { 
       action: add_subscriber, 
       email: entered 
      } 
      $.ajax({ 
       url: 'wp-content/plugins/more-subscribers/addEmail.php', 
       type:'POST', 
       data: ajaxData 
       }).done(function(msg){ 
        alert('Thank you!'); 
        console.log(ajaxData); 
       }); 

     } 
    }); 

}); 

assests.js然後還有另一個php文件試圖在數據庫中創建WP用戶。這也可以在根目錄找到：

<?php 

    add_action('wp_ajax_nopriv_add_subscriber','add_subscriber'); 
    add_action('wp_ajax_add_subscriber','add_subscriber'); 

/* Add email to database */ 
    function addEmail(){ 
     $email = htmlentities($_POST['email']); 
     if(wp_create_user($email,'7777777',$email)) echo 'OK'; 
     die(); 
    } 

?> 

我需要做些什麼才能使它工作？

據只需要修復您的最後一個文檔片斷，你可以嘗試：

<?php 

     add_action('wp_ajax_nopriv_add_subscriber','add_subscriber'); 
     add_action('wp_ajax_add_subscriber','add_subscriber'); 

     // Add the new subscriber 
     function add_subscriber(){ 
      // it's not a good idea to use htmlentities for a username 
      $email = filter_input(INPUT_POST, 'email', FILTER_SANITIZE_EMAIL); 

      // Just a check, if the mail exists 
      if($email != "") { 

       // Does the username exists 
       if(null == username_exists($email)) { 

        // Generate the password and create the user, better than use 7777777, don't forget to give the password to the user 
        $password = wp_generate_password(7, false); 

        $userdata = array(
         'user_login' => $email, 
         'user_pass' => $password, 
         'user_email' => $email, 
         'role'  => 'subscriber' 
        ); 

        $user_id = wp_insert_user($userdata) ; 

        // Check if the user has been created 
        if(!is_wp_error($user_id)) { 

         echo 'OK'; 

        }// if 

       } //if 

      }// if 

     die(); 
    }
