你可以給幫手一個變量，並改變它在CodeIgniter中使用的函數

Question

我正在創建一個表單，我想製作一個自定義錯誤日誌，例如當用戶離開電子郵件爲空時，我想給我的error_helper可變的電子郵件，發送給用戶，他沒有填寫這個變量，並記錄他留下這個空的。我是codeIgniter的入門者，我已閱讀手冊，但沒有找到有用的東西。這裏是我的代碼：

public function submitCheck() { 
    $this->load->model("User"); 
    if(empty($post['email'] || 'email'=="")) 
    { 
     echo "Email is empty."; //This will be changed to a view for user  
     $this->load->helper('error'); //Loading the helper 
     errorLog('Firstname'); //Variable I want to give to the errorLog function. 
     exit(); 
    }  

所以在這裏我給我的錯誤日誌的變量，至極我想在我error_helper使用

function errorLog(){   
    if(errorLog() == 'email') //Here I want to change the error function based on what variable I give to errorLog 
    { 
     log_message('error', 'Email was empty'); 
     exit(); 
    } 
} 

這是可能做或一些其他的方式怎麼可以根據我給我的errorLog變量來改變函數。 在此先感謝

Answer 1

你需要傳遞parameter到您的輔助函數

控制器文件

public function submitCheck() { 
    $this->load->model("User"); 
    if(empty($post['email'])) 
    { 
     // echo "Email is empty."; //This will be changed to a view for user  
     $this->load->helper('error'); //Loading the helper 
    echo $msg= errorLog('Firstname'); //Variable I want to give to the errorLog function. 
    } 

助手文件

function errorLog($var){ // get the variable thet you have pass from your helper   
     if($var == 'email') //Here I want to change the error function based on what variable I give to errorLog 
     { 
      return log_message('error', 'Email was empty');// here you use return type 

     } 
     if($var == 'test') 
     { 
      return log_message('error', 'Test was empty');// here you use return type 

     } 
} 

而且加載幫手controller constructor文件或文件autoload.php

讀取參數的函數：

function errorLog($var){   
    if($var== 'email') //Here I want to change the error function based on what variable I give to errorLog 
    { 
     log_message('error', 'Email was empty'); 
     exit(); 
    } 
}
