控制器/形式做奇怪的事情，當內容被實施

Question

我有下面的控制器，我想它做以下事情：

• 如果用戶名已被顯示錯誤 - >目前只是提交作爲 即使通過特定用戶在數據庫中也是正常的。

• 填充如果有一個錯誤的數據 - >當前與 導入的數據填充，如果正確

• 請選擇下拉菜單項的活動狀態

查看：

<h1><?php echo $companyName; echo nbs(1);?> - <?php echo $pageTitle; ?></h1> 



<?php 
if($success == TRUE) { 
echo '<section id = "validation">Page Updated</section>'; 
} 
?> 
    <p>Error: <?php echo validation_errors();?></p> 
    <div class="formContent"> 
     <form action="createUser" method="post"> 
      <fieldset class="control-group"> 
       <label for="userName">User Name:</label><input type="text" id="userName" name="userName" value="<?php echo set_value('userName'); ?>" placeholder="User Name"> 
       <label for="userPassword">User Password:</label><input type="password" id="userPassword" name="userPassword" value="<?php echo set_value('userPassword'); ?>" placeholder="User Password"> 
       <label for="userFirstName">First Name:</label><input type="text" id="userFirstName" name="userFirstName" value="<?php echo set_value('userFirstName'); ?>" placeholder="First Name"> 
       <label for="userLastName">Last Name:</label><input type="text" id="userLastName" name="userLastName" placeholder="Last Name"> 
       <label for="userEmail">E-Mail:</label> <input type="text" id="userEmail" name="userEmail" placeholder="Admin E-mail"> 
       <label for="userGroup"> User Group:</label> 
        <select name="userGroup" id="userGroup"> 
         <option value="select">Please Select</option> 
         <option value="admin">Admin</option> 
         <option value="user">User</option> 
        </select> 
       <label for="userActive"> User Active:</label> 
         <select name="userActive" id="userActive"> 
          <option value="select">Please Select</option> 
          <option value="yes">Yes</option> 
          <option value="no">No</option> 
         </select> 
       <div> 
        <button type="submit" class="btn-primary">Create</button> 
       </div> 
       </fieldset> 
     </form> 
    </div> 

控制器：

<?php if (! defined('BASEPATH')) exit('No direct script access allowed'); 

class createUser extends CI_Controller { 


    public function index() 
    { 
     //Form Validation prep making sure its all clean 

     $this->form_validation->set_rules('userName', 'User Name', 'trim|required|is_unique[users.userName]|xss_clean'); 
     $this->form_validation->set_rules('userPassword', 'User Password', 'trim|required|xss_clean|sha1'); 
     $this->form_validation->set_rules('userFirstName', 'First Name', 'trim|required|xss_clean'); 
     $this->form_validation->set_rules('userLastName', 'Last Name', 'trim|required|xss_clean'); 
     $this->form_validation->set_rules('userEmail', 'E-Mail', 'trim|required|xss_clean'); 
     $this->form_validation->set_rules('userGroup', 'User Group', 'trim|required|xss_clean'); 
     $this->form_validation->set_rules('userActive', 'User Active', 'trim|required|xss_clean'); 

     //If form validation fails load previous page with errors else do the job and insert data into db 

     if($this->form_validation->run() == FALSE) 
     { 
      $data['success'] = ""; 
     }else{ 
      $username = $this->input->post('userName'); 
      $password = $this->input->post('userPassword'); 
      $firstname = $this->input->post('userFirstName'); 
      $lastname = $this->input->post('userLastName'); 
      $email = $this->input->post('userEmail'); 
      $group = $this->input->post('userGroup'); 
      $active = $this->input->post('userActive'); 

      $passwordHash = $this->encrypt->sha1($password); // Lets encrypt the password why sha1? MD5 is for tossers 

      // If the data is correct follow through with db insert 

      if($this->users_model->createUser($username,$passwordHash,$firstname,$lastname,$email,$group,$active)) 
      { 
       $data['success'] = TRUE; 

      } 

     } 
     $data['companyName'] = $this->core_model->companyName(); 
     $data['pageTitle'] = "Create User"; 
     $this->load->view('admin/assets/header', $data); 
     $this->load->view('admin/createUser', $data); 
     $this->load->view('admin/assets/footer'); 
    } 
}

Answer 1

如果我是你，我會用一個回調（http://codeigniter.com/user_guide/libraries/form_validation.html#callbacks）

 $this->form_validation->set_rules('userName', 'User Name', 'trim|required|xss_clean|callback__checkUsername'); 

爲您選擇下拉菜單，使用SET_VALUE（）函數

   <select name="userGroup" id="userGroup"> 
        <option value="select"<?=(set_value('userGroup')=='select')?' selected="selected"':''?>>Please Select</option> 
        <option value="admin"<?=(set_value('userGroup')=='admin')?' selected="selected"':''?>>Admin</option> 
        <option value="user"<?=(set_value('userGroup')=='user')?' selected="selected"':''?>>User</option> 
       </select> 

好運

我在此要單純從邏輯的PHP點我一無所知笨 至於檢查，如果用戶名已被佔用，我會做用戶名字​​段的數據庫查詢在你的「用戶「表並查看名稱是否存在。

我看你已經這樣做了：

$this->form_validation->set_rules('userName', 'User Name', 'trim|required|is_unique[users.userName]|xss_clean'); 

我不知道在點火器引用數據庫表的標準，但也許你不正確引用的字段。另外，我會檢查每一個小寫字母，以確保您檢查不區分大小寫，除非您想要區分大小寫的用戶名。
