在模型中的函数之间传递变量

Question

I have such function in model.

function news() 
{
    $data = array(
        'title' => $this->input->post('title'),
        'date'  => $this->input->post('date'),
        'newstext' => $this->input->post('newstext'),
    );
    $this->db->insert('news', $data);
}

And I want use this $data['title'] in another function inside the same model. How can I do that?

Answer 1

首先，我认为最好将输入值存储在控制器中，而不要在模型中存储以遵循MVC模式，因此您的模型中只有数据库相关的操作，然后，您可以调用该函数，并将控制器中的另一个函数传递给两个函数输入您存储在控制器中的值。

The easiest way to accomplish that:

Declare a global variable right after the Model Class definition.

eg

class ModalName extends CI_Model()
{
    public $title;

    function news() 
    {
        $data = array(
            'title' => $this->input->post('title'),
            'date'  => $this->input->post('date'),
            'newstext' => $this->input->post('newstext'),
        );
        $this->db->insert('news', $data);
        $this->title = $data['title'];
    }
}

Then ,

$this->title will be available in every function inside your Model Class.
