Duplicate rows CodeIgniter - php

Question

Im encourting a problem with my "add" function on the "subscriptions" model.
1% of the registerations is duplicated(2 or even up to 5 times) for some reason.
this is the code im using:
public function add($service, $phone, $sushi_subscription_id, $answer_id, $affiliate_id, $ip, $query, $invite_type, $invite_msg_id)
{
$this->db->set('service_id', $service->id);
$this->db->set('sushi_service_id', $service->sushi_service_id);
$this->db->set('phone', $phone);
if ($sushi_subscription_id)
{
$this->db->set('sushi_subscription_id', $sushi_subscription_id);
}
$this->db->set('answer_id', $answer_id);
if ($affiliate_id)
{
$this->db->set('affiliate_id', $affiliate_id);
}
$this->db->set('added', 'NOW()', FALSE);
$this->db->set('active', 1);
$this->db->set('ip', $ip);
$this->db->set('query', $query);
if ($invite_type)
{
$this->db->set('invite_type', $invite_type);
}
if ($invite_msg_id)
{
$this->db->set('invite_msg_id', $invite_msg_id);
}
return ($this->db->insert($this->_table_name)) ? $this->db->insert_id() : FALSE;
}
any idea how I could avoid this from happaning? the row is exactly the same.
service_id, phone, active, even the added date!

Answer 1

Although it is not totally irrelevant but it is very useful to build up your own generic functions or modules that serves your requirements. Here is check_duplicate function working as generic function checking duplicate data entry in DB. Here is the function
function _check_duplicate($table_name,$param)
{
$row_count=$this->db->get_where($table_name,$param)->num_rows();
if(count($row_count>0))
{
return true;
}
else
{
return false;
}
}
here is how you call the function;
if($this->_check_duplicate('table_name',array('param1'=>$param1,'param2'=>$param2)))
{
// redirect to some page
}
else
{
// do something, insert or update
}
for parameters, you can pass as many parameters as required. this function can be generic in a controller or can be part of generic module. It depends how you use it.

I think this code will help you.....
//model
function add($data){
$this->db->insert($this->table, $data);
$this->session->set_flashdata("message", "Record successfully created.");
}
//in your controller
function create(){
$data = array( 'service_id' => $this->input->post('service_id'),
'sushi_service_id' => $this->input->post('sushi_service_id'),
'phone' => $this->input->post('phone'),
'sushi_subscription_id' => $this->input->post('sushi_subscription_id'),
'answer_id' => $this->input->post('answer_id'),
'affiliate_id' => $this->input->post('affiliate_id'),
'' => $this->input->post(), // and so on and so on just like that copy and do that
//add more here
);
$this->"model name"->add($data);
}
//view
<form action="<?=site_url('controller_name/create');?>" method = "POST">//the word create is the function name and dont forget to change the controller name
<input type="text" name="service_id"/>
<input type="text" name="sushi_service_id"/>
<input type="text" name="phone"/>
//and so on and so on....just copy and do like that
<input type="submit"/>
</form>
