How to pass multiple model functions from controller to view in codeigniter?

Question

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..

Can you spot the line which causes the error based on the message you get? Is it $data = $var1 + $var2 + $var3; — raidenace

Yes that was what the error was suggesting however the problem was in the model. One of the vars wasn't being returning properly which was throwing that exception. I added an If to ensure to check for num_rows and all is working again. Thanks — MrPizzaFace

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);

just to expand on this, the "Fatal error: Unsupported operand types" means that one or all of your $var are not arrays but could be variables. In order to do "+", all variables must be arrays. What Otporan is doing is declaring the $var within the array rather than relying on "+".

You might also want to take into mind using variable names that actually mean something ie $data['userdata']=$this->model_name->function_name();

You can also use the compact function for less code. e.g. $this->load->view('view_path', compact('var1', 'var2', 'var3'));
