Declare variables outside of loop - JayAdra - 09-28-2015

Declare your variables outside of the foreach loop.

PHP Code:
$untung = 0;
$ongkir = 0;

foreach ($sum->result() as $row) {
  $untung=$row->jumlah_item;    
}

foreach ($sumongkir->result() as $row) {
  $ongkir=($row->total);
}

$total=$untung+$ongkir;

Assume two query result in the same size

PHP Code:
// assume $sum->num_rows() == $sumongkir->num_rows()
for ($i = 0; $i < $sum->num_rows(); ++$i) {
    $untung=$sum->row($i)->jumlah_item;
    $ongkir=$sumongkir->row($i)->total;
    $total+=$untung+$ongkir;    
} 

Not sure I understand your question correctly but I think $total may be an array $total[$i]

PHP Code:
// assume $sum->num_rows() == $sumongkir->num_rows() for ($i = 0; $i < $sum->num_rows(); ++$i) { $untung=$sum->row($i)->jumlah_item; $ongkir=$sumongkir->row($i)->total; $total+=$untung+$ongkir; }

Maybe I misunderstand something. If you use foreach your way, you only get the last row of the result set. So it something similar to following without the foreach:

PHP Code:
$untung = $sum->last_row()->jumlah_item;
$ongkir = $sumongkir->last_row()->total;
$total = $untung + $ongkir;
