在Codeigniter 1.7.2中将数据从模型发送到控制器

Question

I am receiving $fb_data[uid] ie Facebook UID from my model and I want to put this variable's value into my controller where the signup process is taking place passing fields in controller like this:

$sql_data = array('student_fname' => $student_fname, 'student_sname' => $student_sname, 'student_org' => $student_org, 'student_title' => $student_title, 'student_uid' => ?

I am confused how to insert the Facebook UID value here at my controller..

Answer 1

You need to have a function in your model which returns your $fb_data . In the controller you have (if not already done) to load the model

$this->load->model('model_name');

Then you can access your model function from the controller by calling

$this->model_name->function_name();

The section 'loading a model' in the CI documentation explains it again.

Answer 2

Do like this :

First create one method in controller :

Ex : In controller

function fbcontent() {
$this->load->model('your model name');
$content = $this->model_name->fbaction();
}

and In model

function fbaction(){
$sql_data = array('student_fname' => $student_fname, 'student_sname' => $student_sname, 'student_org' => $student_org, 'student_title' => $student_title, 'student_uid' => ?
return $sql_data;
}
