CodeIgniter - Checking to see if a slug already exists in the database - php

Question

I Have made a function add_items. and I Want if the slug already exists in the database then the form_validation runs and shows the error message. and that's work fine if the slug exists. But the main problem is that if I want to insert the new Data in the database which obviously has a different slug then the data is not inserted.
public function add_items()
{
if($this->input->post()){
if($this->input->is_ajax_request()){
$title = $this->input->post('title');
$url_title = url_title($title);
$this->form_validation->set_rules($url_title,'callback_slug_exists');
if($this->form_validation->run() == FALSE)
{
echo "FAIL::Slug Already Exist::error";
return;
}
$item_price = $this->input->post('item_price');
$item_description = $this->input->post('item_description');
$insertData = array('item_title' =>$title,'item_url'=>$url_title,'item_price' =>$item_price,'item_description'=>$item_description,
'big_pic' =>$image_path."/".$image);
$result = $this->common_model->insert_record('store_items',$insertData);
if($result){
echo "OK::Record Inserted Successfully::success";
return;
}
else {
echo "FAIL::Record Insertion Failled::success";
return;
}
}
}
$this->show('admin/add_items.php');
}
Here are The function slug_exists()
function slug_exists($slug)
{
$this->common_model->slug_exists($slug);
}
This is in Model
function slug_exists($slug)
{
$this->db->where('item_url',$slug);
$query = $this->db->get('store_items');
if ($query->num_rows() > 0){
return true;
}
else{
return false;
}
}
This is the insert_record()
function insert_record($tbl, $data)
{
$this->db->insert($tbl, $data);
return $this->db->insert_id();
}
And this is DB Structure

Answer 1

try this:you can post data direct in an array. no need define it.
$insertArray=array(
item_title' =>$this->input->post('title'),
'item_url'=>$this->input->post('url_title'),
'item_price' =>$this->input->post('item_price'),
'item_description'=>$this->input->post('item_description'),
'big_pic' =>$image_path."/".$image);
$this->db->insert('store_items', $insertArray);

Answer 2

Try like this
function slug_exists($slug)
{
$this->db->where('item_url',$slug);
$query = $this->db->get('store_items');
if ($query->num_rows() > 0){
return false;
}
else{
return true;
}
}
If slug already exists then you need to fail the validation to get the error so return false on existing
Also, return the answer/result to a callback function
function slug_exists($slug)
{
return $this->common_model->slug_exists($slug);
}
Update
Controller
if($this->form_validation->run() == FALSE){
echo "FAIL::Slug Already Exist::error";
return;
}else{
$item_price = $this->input->post('item_price');
$item_description = $this->input->post('item_description');
$insertData = array('item_title' =>$title,'item_url'=>$url_title,'item_price' =>$item_price,'item_description'=>$item_description,
'big_pic' =>$image_path."/".$image);
$result = $this->common_model->insert_record('store_items',$insertData);
if($result){
echo "OK::Record Inserted Successfully::success";
return;
}
else {
echo "FAIL::Record Insertion Failled::success";
return;
}
}
