Codeigniter multiple parameter on update - codeigniter

Question

I am copying this code in Codeigniter official docs, but I don't know why this will throw an error
public function acceptChangeRequest($id,$data1,$accept) {
$data = array(
'status' => $accept,
'approve_by' => $data1,
);
$this->db->where('id', $id);
$this->db->update('change_request',$data);
//return true;
}
Error Number: 1054
Unknown column 'Array' in 'field list'
UPDATE change_request SET status = 'Y', approve_by = Array WHERE id = '22'
It sounds wierd since this code works in my other function. Any idea?

Answer 1

Read The Documentation Clearly
Read About Update Records In Codeigniter
Here IS Demo Function For You
public function updateBasic($data,$user_id){
$userData=array(
'marital_status'=>$data['marital_status'],
'country'=>$data['stateofresidence'],
'city'=>$data['city'],
'caste'=>$data['caste'],
'residential_status'=>$data['residencystatus']
);
$this->db->WHERE('user_id',$user_id)->update('basic_profile',$userData);
return true;
}
You Must Check Through Print_r();what Is coming To your Function In Your Case $data1 Is Coming In the From OF array You Must Extract The Array To Update The Record

Answer 2

Use this function in your model to update the record.
public function acceptChangeRequest($where, $table, $data){
$this->db->where($where);
$this->db->update($table, $data);
return $this->db->affected_rows() > 0;
}
use this code in your controller.
$where = array('id'=>$id);
$data = array(
'status' => $accept,
'approve_by' => $data1,
);
$this->User_model->update($where,'table_name',$data);

Answer 3

What is in your $data1 variable? I can see that it's an array, and that is the problem.
If your $data1 stores indexes like in your table's row, than this is the possible solution for you:
public function acceptChangeRequest($id,$data1,$accept) {
$data1["status"] = $accept;
$this->db->where('id', $id);
$this->db->update('change_request', $data1);
return true;
}
But if your $data1 variable stores only the approve_by information, than your possible solution is:
public function acceptChangeRequest($id,$data1,$accept) {
$data = array(
'status' => $accept,
'approve_by' => $data1["approve_by"]
);
$this->db->where('id', $id);
$this->db->update('change_request', $data);
return true;
}
First of all, you need to know what you expect from $data1, than you can move forward to the solution.
You can see your $data1 variable in your Controller's function:
print "<pre>";
print_r($data1);
print "<pre>";
die();
