How to update or insert new data on codeigniter - php

Question

I'm setting up a rest-API on my server, and I want to update a table (i.e "comp_holding_stock"). but every time I test to post new data it returns "No item found"
Here is my controller
public function create_comp_holding_stock(){
$returnArr['status'] = '0';
$returnArr['response'] = '';
try {
if (!$this->input->post()) {
$returnArr['response'] = "Only POST method is allowed";
} else {
$holding_stock_data = array(
'comp_id' => $this->input->post('comp_id'),
'customer_id' => $this->input->post('customer_id'),
'quantity' => $this->input->post('quantity'),
'date' => date('Y-m-d H:i:s')
);
if (!isset($holding_stock_data)) {
$returnArr['response'] = "Some Parameters are missing";
} else {
$customer = $this->Customer->save_holding_stock($holding_stock_data);
if (!$customer) {
$returnArr['response'] = 'No items found';
} else {
$returnArr['status'] = '1';
$returnArr['response'] = $customer;
}
}
}
} catch (Exception $ex) {
$returnArr['response'] = "Error in connection";
$returnArr['error'] = $ex->getMessage();
}
$response = json_encode($returnArr, JSON_PRETTY_PRINT);
echo $response;
}
And here is my model below
public function save_holding_stock($holding_stock_data)
{
// $this->db->trans_start();
$success = $this->db->insert('comp_holding_stock', $holding_stock_data);
return $success;;
}
what am i doing wrong? what is the best approach to this scenarios

Answer 1

I would recommend try to check if you have load model in your controller.
And in your model try to do this.
public function save_holding_stock($holding_stock_data, $comp_id=FALSE)
{
if(!$comp_id == -1 || !$this->exists($comp_id))
{
if($this->db->insert('comp_holding_stock', $holding_stock_data))
{
$holding_stock_data['comp_id'] = $this->db->insert_id();
return TRUE;
}
return FALSE;
}
$this->db->where('comp_id', $comp_id);
return $this->db->update('comp_holding_stock', $holding_stock_data);
}

Try these changes in your code
In your controller,
$customer = $this->Customer->save_holding_stock($holding_stock_data);
$save_status = $this->db->affected_rows();
if ($save_status>0) {
$returnArr['status'] = '1';
$returnArr['response'] = $customer;
} else {
$returnArr['response'] = 'No items found';
}
In your model,
public function save_holding_stock($holding_stock_data)
{
// $this->db->trans_start();
$this->db->insert('comp_holding_stock', $holding_stock_data);
}
