random error

$result->first_name will be "Object". When you use ->result() you will need to iterate through the result(even if it only has one row). As you are expecting only one row, use ->row() instead.

As cahva mentioned, you would want to use:

Code:

$database_row = $this->db->get('members');
$result = $database_row->row(0);
        
        if(count($result)> 0) {
            $data = array(
                    'email' => $this->input->post('email'),
                    'first_name' => $result->first_name,
                    'is_logged_in' => true

            );
            $this->session->set_userdata($data);
        }

wow thanks a lot guys, the problems fixed and now i can display the users data! i was stuck for ages and im going to post my fixed code as i know its frustrating when people get a fix and never give thanks and conclude the problem to the people who helped em in the first place:

Code:

function login_validation() {
        $this->load->model('membership_model');
        $query = $this->membership_model->login_validation();

        $this->db->where('email', $this->input->post('email')); //this line checks against what the user input as an email and filters out the results in the database
        $this->db->where('password', md5($this->input->post('password'))); //this line checks against what the user input as a password and filters out the results in the database
        $database_row = $this->db->get('members'); //this then retrieves the rows filtered by the two above statements
        $result = $database_row->row(); //this is like the result() method but is used when only one row is in question/ being retrieved
        
        
        if($query) { //if $query is true or runs without errors
            $data = array( //assigns values to the variable '$data'
                    'email' => $this->input->post('email'),
                    'first_name' => $result->first_name,
                    'last_name' => $result->last_name,
                    'full_name' => "$result->first_name" . " $result->last_name",
                    'is_logged_in' => true
            );
            
            $this->session->set_userdata($data); //passes the variable '$data' to the set_userdata() method and hence the sessions userdata is set
            redirect('main'); //redirects us back to the main function
        }
        
        else {
            $this->load->view('main_page'); //else if $query is not true or doesnt run the main_page view is loaded
        }
    }

thanks again :)
