How to test if Ci successfully inserted data

Question

In Ci, I've got the following function. How do I test that the query successfully inserted without error's?

public function postToWall() {
    $entryData = $this->input->post('entryData');
    $myChurchId  = $this->session->userdata("myChurchId");
    $this->db->query("INSERT IGNORE INTO wallPosts (entryData, entryCreationDateTime, wpChurchId)
                      VALUES('$entryData', NOW(), '$myChurchId')");
}

Answer 1

You can use $this->db->affected_rows() function of codeigniter.

See more information here

You can do something like this:

return ($this->db->affected_rows() != 1) ? false : true;

Listless

Or simply: return $this->db->affected_rows() > 0; – Marcellamarcelle

Answer 2

You can also do it using Transactions like this:

           $this->db->trans_start();
           $this->db->query("INSERT IGNORE INTO wallPosts (entryData, entryCreationDateTime, wpChurchId)
                      VALUES('$entryData', NOW(), '$myChurchId')");
           $this->db->trans_complete();

           if ($this->db->trans_status() === FALSE) {
               return "Query Failed";
           } else {
               // do whatever you want to do on query success
           }

Here's more info on Transactions in CodeIgniter!

Answer 3

if you are using bootstrap on codeigniter try flash message or simply redirect

$added = $this->your_modal->function_reference($data);


if ($added) {
    $this->session->set_flashdata('success', 'Added successfully.');
    redirect('home');
} else {
    $this->session->set_flashdata('error', 'Something wrong.');
    redirect('home');

Codeigniter 4:

    $db = db_connect();
     (your insert query)
    return ($db->affectedRows() != 1) ? false : true;
