CI框架经验总结

1. CI里面load的时候加载model是不可以在构造方法里面传参/比如我想自定义异常代码如下

<?php
class CrmException extends Exception {

    public function __construct() {
        parent::__construct();
    }

    public function initialise($message ,  $code  =  0 )
    {
        $this->code = $code;
        $this->message = $message;
    }

    public function errorMessage()
      {
      //error message
          $errorMsg = 'Error on line '.$this->getLine().' in '.$this->getFile()
      .': '.$this->getMessage().' is not a valid E-Mail address';
          return $errorMsg;
     }
    public function getCustom() {
        return Array("code" => $this->code, "message" => $this->message);
    }
}
/* End of file Result.php */
/* Location: ./system/models/common/CrmException.php */

可以将自定义的参数放在另外一个方法里面

引用的时候
function test() {
        $this->load->model("common/CrmException");
        try {
            $object = new CrmException();
            $object->initialise("info" ,  400 );
            throw $object;
        } catch (CrmException $e) {      // 捕获异常
            print_r( $e->getCustom());
        }
    }

感觉有些怪怪的...
