Hello. I have a function which performs and insert, however when the user enters a value where the primary key is duplicated it gives an error. I understand why, but I am not sure how to handle it. Please see my code below. THANKS!!!!
controller:
Code:
function update_app()
{
//set common properites.
//get the id of the process from the url
$proid = $this->uri->segment(3);
$sysId = $this->input->post('sys');
$sys_name = $this->department_model->get_sys_name(24);
$sysName= $sys_name->result();
$sysn = $sysName[0]->SystemName;
$res = array('SystemID' => $this->input->post('sys'),
'ProcessId' => $this->input->post('pro'),
'Priority' => $this->input->post('prio'),
'RTO'=> $this->input->post('rto'),
'RPO'=> $this->input->post('rpo'),
'Location'=> $this->input->post('loc'),
'Description' => $this->input->post('exp')
);
$flag = $this->department_model->addSystemProcess($proid,$sysId, $res);
if($flag == "TRUE")
{
$this->session->set_flashdata('success', 'Application Sucessfully Added!');
redirect('bia/app_sys/' . $this->session->userdata('deptId'), 'refresh');
}
if($flag == "FALSE")
{
$this->session->set_flashdata('success', 'Error.!');
$this->load->view('addApp', $data);
}
}
Model:
Code:
function addSystemProcess($proId, $sysId, $resp)
{
$this->db->where('ProcessId', $proId);
$this->db->where('SystemID', $sysId);
$insert = $this->db->insert('processsystem', $resp);
return ($insert->db->affected_rows() > 0) ? TRUE : FALSE;
}
THe error which I am getting is:
Code:
Error Number: 1062
Duplicate entry '2-23' for key 'PRIMARY'
INSERT INTO `processsystem` (`SystemID`, `ProcessId`, `Priority`, `RTO`, `RPO`, `Location`, `Description`) VALUES ('23', '2', 'Vital', '', '', '', '')
THanks in advance!
