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

The easiest way to accomplish that:

Declare a global variable right after the Model Class definition.

e.g.

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.
