Product listing issue

-- url of the page with the problem -- : eduquay.satumalaysiahosting.com/products

The products aren't appropriately displayed as I made some modifications as below.

---

$class[]= new stdClass();
$i=0;
foreach($this->rows as $row)
{
if(in_array((int)$row->product_vendor_id,$vendors))
{
$class[$i]=$row;
$i++;
}
}
$this->rows=$class;

---

The new rows are the filtered products from the original rows within the limit of 18. However, I would like to filter from all products rather than only 18 rows.

Is there any possible way to temporarily change the limit while selecting the rows?

Much appreciated for your help!
