Question

I am just grabbing user data from a few tables but users have the option of adding more than one skill or exp.

$query_str = "SELECT a.*, b.*, c.*, d.*, e.* FROM edu a
              JOIN exp b ON a.user_id=b.user_id
              JOIN user_profiles c ON a.user_id=c.user_id
              JOIN skills d ON a.user_id=d.user_id
              JOIN comp e ON a.user_id=e.user_id
              WHERE a.user_id = ?";

$query = $this->db->query($query_str, $end_user);
            if($query->num_rows() > 0) {
                    foreach($query->result_array() as $stuff) {
                            $data[] = $stuff;
                    }
                    return $data;
                    } else {
            return false;
                    }

Everything is fine until I try to display the data. If a user has two exp, everything else is showing up twice. I m not sure how to write this. Would it be easier to do separate them? One query for each item?

public function get_education()
    {
           $one_edu = $this->test_model->one_edu($end_user);
            if ($one_edu != false)
            {
                    foreach($one_edu as $edas) {
                            $one_edu_html .='<p>'.$edas['objective'].'</p>';
                    }

                    foreach($one_edu as $exp) {
                            $one_edu_html .= '<p>'.$exp['exp_title'].'</p>';

                    }

                    foreach($one_edu as $educ) {
                            $one_edu_html .= '<p>'.$educ['edu_title'].'</p>';
                    }

                    $result = array('status' => 'ok', 'content' => $one_edu_html);
                    echo json_encode($result);
                    exit();
            }else{
                    $result = array('status' => 'ok', 'content' => '');
                    echo json_encode($result);
                    exit();
            }
    }

Now it s returning something like this:

Objective
Exp title1
Exp title2
Edu title
Edu title <- Extra

Using codeigniter

Answer 1

The main reason for this is because you haven’t grouped your rows. Add a grouper, like GROUP BY a.id at the end

Update

The rows are duplicating because they are different, you can group the field on a single rows, using GROUP_CONCAT

SELECT a.user_id, a.education, GROUP_CONCAT(a.edu_title SEPARATOR ",") "Edu_Title", GROUP_CONCAT(b.exp_title SEPARATOR ",") "Experience Title" ,b.experience, c.objective, d.skill, e.comp FROM edu a
JOIN exp b ON a.user_id=b.user_id
JOIN user_profiles c ON a.user_id=c.user_id
JOIN skills d ON a.user_id=d.user_id
JOIN comp e ON a.user_id=e.user_id
WHERE a.user_id = 243;
