Question

I am unable to identify the mistake
model (here I am matching the id to update)
function get_account_record($a_id)
{
$this->db->where('a_id', $a_id);
$this->db->from('account_info');
$query = $this->db->get();
return $query->result();
}
controller (receiving everything via post accept the ID i-e a_id )
function update($a_id)
{
$data['a_id'] = $a_id;
$data['view'] = $this->sf_model->get_account_record($a_id);
$this->form_validation->set_rules('a_name', 'Account Name', 'trim|required|xss_clean|callback_alpha_only_space');
$this->form_validation->set_rules('a_web', 'Website', 'trim|required|xss_clean');
form Validation
if ($this->form_validation->run() == FALSE)
{
$this->load->view('viewUpdate', $data);
}
else {
$data = array(
'a_name' => $this->input->post('a_name'),
'a_website' => $this->input->post('a_web'),
'a_billingStreet' => $this->input->post('a_billingStreet'),
'a_mobile' => $this->input->post('a_mobile'),);
$this->db->where('a_id', $a_id);
$this->db->update('account_info', $data);
display success message
$this->session->set_flashdata('msg','<div class="alert alert-success text-center">Successfully Updated!</div>');
//redirect('salesforce' . $a_id);
}
}

Answer 1

If you don't want to allow the user to edit then add readonly instead of disabled attribute
<div class="col-lg-8 col-sm-8">
<input id="a_id" name="a_id" placeholder="" readonly="readonly" type="text" class="form-control" value="<?php echo $a_id;?>" />
<span class="text-danger"><?php echo form_error('a_id'); ?></span>
</div>
If you want to disable then add the hidden element
<input id="a1_id" name="a1_id" type="hidden" value="<?php echo $a_id;?>" />
Controller Function
function update($a_id)
{
//read the value using input library
$a_id = $this->input->post('a_id');
//$a1_id = $this->input->post('a1_id'); your hidden element value can be get here.
$data['a_id'] = $a_id;
$data['view'] = $this->sf_model->get_account_record($a_id);
$this->form_validation->set_rules('a_name', 'Account Name', 'trim|required|xss_clean|callback_alpha_only_space');
$this->form_validation->set_rules('a_web', 'Website', 'trim|required|xss_clean');
}

My problem Solved after editing the where clause in update query
$this->db->where('a_id', $_POST['a_id']);
