Help Need Controller and Accessing Object - El Forum - 05-21-2013

Hello folks, I am new here and have a small issue.
The problem is with understanding how i can access an result in controller.
I got an error message like “Trying to get property of non-object” on line…
I want to do some like this.
function get_something($some_var){
$this->load->model('some_model','',TRUE);
$data['query'] = $this->some_model->get_some_thing($some_var);
if($data['query']->col2==some_value){ //<--this will be the line where i get the error.
$this->load->view('view_1',$data);
}else{
$this->load->view('view_2',$data);
}
}
Nick Carangi pointed this out, i know my mistake but i don’t understand how i can access the value. normally in the view i do some like this
foreach($query as $row):
echo "col2: ".$row->col2;
and so on but i want access the value in the controller
the function in some_model looks like this…
function get_some_thing($some_var){
$this->db->select('col1');
$this->db->select('col2');
$this->db->select('col3');
$this->db->where('col1',$some_var);
$data = $this->db->get('some_table');
return $data->result();
}

1. Make sure that your query inside your model method "get_some_thing", actualy returns something. If it doesn't than your tries to access the result object rows will always return the error of "Trying to access property of a non objec", since what the object $data will be equal then is a boolean value of "false" , since that is what is returned from your model if the query was not successful.
2.Try to do and IF statement like this : "if($data->col2 == "some value") { run some code here } else { some other code } (notice that there is no $data['query'], but $data on it's own

Welcome to the CodeIgniter forums!
You're trying to use an array as an object. return $data->result() returns an array of objects, so you will need to loop through the array to access each object. If you're only expecting a single row of data, use row() instead of result(), which will pass back an object, and not an array of objects.
