Answer 1

use intval before integer values..
intval($this->input->post('quantity2'))

Answer 2

It will be better if you use variables to insert batch data.
$purchase_quantity=empty($this->input->post('quantity3'))==true?0:$this->input->post('quantity3');
And use this $purchase_quantity in array to insert.
The code above will check if quantitiy3 have empty value (ie 0,null or false) it will replace with 0 (An integer) and save in variable that you can use in array to insert

Answer 3

you can set the values as null or default value if form elements are empty like this..
'date'=>($this->input->post('date'))?$this->input->post('date'):null;
or
'date'=>($this->input->post('date'))?$this->input->post('date'):date('Y-m-d');
Or do like this if you want to ignore insert totally:
$data = array();
for($i=1;$i<=25;$i++)
{
if($i>1)
{
if($this->input->post('vendor_name'.$i) && $this->input->post('model'.$i) && $this->input->post('price'.$i) && $this->input->post('quantity'.$i))
{
$record = array(
'date'=> $this->input->post('date'),
'vendor_name'=>$this->input->post('vendor_name'.$i),
'model'=>$this->input->post('model'.$i),
'price' =>$this->input->post('price'.$i),
'purchase_quantity'=>$this->input->post('quantity'.$i),
'amount' =>$this->input->post('price'.$i)*$this->input->post('quantity'.$i),
'invoice_no'=>$this->input->post('invoice')
);
$data[]=$record;
}
}
else{
if($this->input->post('vendor_name') && $this->input->post('model') && $this->input->post('price') && $this->input->post('quantity'))
{
$record = array(
'date'=> $this->input->post('date'),
'vendor_name'=>$this->input->post('vendor_name'),
'model'=>$this->input->post('model'),
'price' =>$this->input->post('price'),
'purchase_quantity'=>$this->input->post('quantity'),
'amount' =>$this->input->post('price')*$this->input->post('quantity'),
'invoice_no'=>$this->input->post('invoice')
);
$data[]=$record;
}
}
}
