Question

I want to update a table field with a new value provided like

if the field current value is 100 once updated with value 200, it should be 100,200

so i tried

$this->db->set('return', 'CONCAT(return,',','.$loan_number.')', FALSE); 
$this->db->where( 'id', $this->input->post('id') );
$this->db->update('tbl_test'); 

i think im using CONCAT in wrong way though.

any idea how to get this work?

Regards

You have a problem with you quotes. This code gives four parameters to $this->db->set(): return, CONCAT(return,, ,'{loan_number} and FALSE. Your trying to append ,{loan_number} to return right? If so then you should either escape you quotes ore use different quotes.

Escaping:

$this->db->set('return', 'CONCAT(return,\',\',\''.$loan_number.'\')', FALSE);

Different qutes:

$this->db->set('return', "CONCAT(return,',','".$loan_number."')", FALSE);
