如何将模型加载到帮助器？ [英] How can I load model to helper?

问题描述

如何将模型加载到帮助程序？我需要将它加载到函数之外，但在函数中使用它们。

How can I load model to helper? I need to load it outside of functions, but use them in functions.

推荐答案

function my_helper()
{
    // Get a reference to the controller object
    $CI = get_instance();

    // You may need to load the model if it hasn't been pre-loaded
    $CI->load->model('my_model');

    // Call a function of the model
    $CI->my_model->do_something();
}

另一个选择是在调用辅助函数时传递模型。 p>

Another option is to pass the model in when calling the helper function.

function my_helper($my_model)
{
    $my_model->do_something();
}

function my_controller_action()
{
    // Call the helper function, passing in the model
    my_helper($this->my_model);
}
