Adding an Array multiple times in the DB via Controller - php

Question

I'm having an issue producing this array multiple times upon how many coupons purchased.
Now it looks like
$coupon_array = array(
'user_id'=>$_POST["user_id"],
'mergent_id'=>$_POST["merchant_id"],
'deals_id'=>$_POST["deal_id"],
'order_id'=>$order_id,
'secret'=>$secret,
'expire_time'=>$time,
'create_time'=>$time,
'status'=>1
);
$this->common_model->insertData('coupon', $coupon_array);
But i have a post value such as:
"quantity"=>$_POST["quantity"]
and i would like to produce this X times. Example:
$quantity x $this->common_model->insertData('coupon', $coupon_array);
Sorry for my english, and i hope i explain this so it's understandable... ;)
Another one! when we insert the coupons they all have the same md5($secret), is it possible to have that also with all the different code...
$secret = md5($secret);
$coupon_array = array(
'user_id'=>$_POST["user_id"],
'mergent_id'=>$_POST["merchant_id"],
'deals_id'=>$_POST["deal_id"],
'order_id'=>$order_id,
'secret'=>$secret,
'expire_time'=>$time,
'create_time'=>$time,
'status'=>1
);

Answer 1

Well, if I understand what you want, you can use for, but that's obvious:
for($i=0; $i<$this->input->post('quantity');$i++) {
$coupon_array['secret'] = md5($coupon_array['secret'].$i);
$this->common_model->insertData('coupon', $coupon_array);
}
Also, never use $_POST["..."] in CodeIgniter, use only $this->input->post('...') as it escapes properly. More info about input class can be found here.

Answer 2

for ($i=0; $i<$quanity; $i++) {
$this->common_model->insertData('coupon', $coupon_array);
}
