php validation from array form - php

Question

I have a code like this
First looping count how many post the array:
for($i = 0; $i < $jumlah_qty ;$i++) {
if(!empty($qty[$i]) && !empty($id_cat[$i])) {
Insert booking:
$insert_booking_hd = $user_class->select($az);
$id_cates = $id_cat[$i];
for($b = 0;$b<$qty[$i];$b++) {
First validation if $_POST[$id_cates) is set run this code:
if(isset($_POST[$id_cates."".$b])){
$id_seat = $_POST[$id_cates."".$b];
Find the seat number in $select_seat and find if seat number is exist in $seat_number:
$select_seat = $user_class->select($query);
$seat_number = $user_class->select($querys);
$row_seat = $user_class->numrows($select_seat);
$row_seat2 = $user_class->numrows($seat_number);
if($row_seat>0) {
$update_seat = $user_class->update($update_false);
$bol[$b] = FALSE;
} else {
if( $row_seat2>0 ) {
$insert_booking_dt = $user_class->insert($insert);
$update_seat = $user_class->update($update_true);
$bol[$b] = TRUE;
} else {
$bol[$b] = FALSE;
}
}
} else {
$insert_booking_dt = $user_class->insert($insert_without_seat);
$bol[$b] = TRUE;
}
if($bol[$b]) {
echo "FALSE";
header("location:../../../print.php?id=$id_booking");
}
else {
echo "WRONG";
header("location:../../../event.php?msg=Same seat number");
}
}
}
}
Anything wrong with my php validation?
Because if I input array of $id_seat it will always redirect to print.php although validation is FALSE
for example if I input 3 array and then I echo FALSE WRONG FALSE FALSE
still redirect to print.php not to event.php
How can I read if one of array is get WRONG and then redirect to event.php?

You may break out of for-loops.
Instead of:
else {
echo "WRONG";
header("location:../../../event.php?msg=Same seat number");
}
You could try:
else {
echo "WRONG";
header("location:../../../event.php?msg=Same seat number");
break 2;
}
