How to pass multiple model functions from controll

问题:

Controller

I have multiple functions from the model passing data to the view

I was doing this successfully like this:

$var1 = $this->model_name->function_name();
$var2 = $this->model_name->function_name();
$var3 = $this->model_name->function_name();

$data = $var1 + $var2 + $var3; 

$this->load->view('page_name', $data);

Now I am using the above method in other areas which is working flawlessly. However I am getting an error Fatal error: Unsupported operand types What happened? Why was it working an hour ago and suddenly broke without modification to the code..

You should put multiple variables into array like this:

$var1 = $this->model_name->function_name();
$var2 = $this->model_name->function_name();
$var3 = $this->model_name->function_name();

$data = array(
               'var1' => $var1,
               'var2' => $var2,
               'var3' => $var3,
          );

$this->load->view('page_name', $data);

or as Rick suggested you can use this:

$data = array();
$data['var1'] = $this->model_name->function_name();
$data['var2'] = $this->model_name->function_name();
$data['var3'] = $this->model_name->function_name();

$this->load->view('page_name', $data);
