将控制器中定义的变量传递给CodeIgniter下的模型

问题描述：

I defined a variable in a method inside controller e.g.

class test extends CI_Controller {
    function tester() {
    $variable = 'value'
    }
}

Now I want to call this variable in my model. How is that possible?

Edit: I use CodeIgniter.

我在控制器内的方法中定义了一个变量，例如 p>

   class test扩展CI_Controller {
 function tester（）{
 $ variable ='value'
} 
} 
  code>  pre> 
 
 现在我想调用这个变量 在我的模型中。 怎么可能？ p> 
 
 
编辑：我使用CodeIgniter。 p> 
  div>

Model:

class your_model extends CI_Model {
    var $variable;

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

    function set_variable($variable) {
        $this->variable = $variable;
    }

}

Controller:

class test extends CI_Controller {
    function tester() {
        $this->load->model('your_model');
        $variable = 'value'
        $this->your_model->set_variable($variable); 
    }
}

答

FYI - if you need a variable available for more then one method in a controller and/or in your model - you can set it in the 'constructor' of the class. Use $this-> before the variable name.

 class Test extends CI_Controller {

 public function __construct() {

 parent::__construct();

  // Set var in construct  
  $this->variable123 = 'some value 123' ;

} // end construct

You can now call $this->variable123 from anywhere in the class and it will be available. If you load a model from this class, it will be available to any method in the model.
