Question

I have the following structure:

Table: products

id, name, sort_order

Let’s say I only have 5 products, but I want 20.

How would I loop through to get 20 results?

Additionally, I’ll need to start at a specific sort_order. So let’s say I have

1,2,3,4,5

and I want to get 20 results and start at 3. It should end up as:

3,4,5,1,2,3,4,5,1,2,3,4,5,1,2,3,4,5,etc.

Any ideas? I’m totally lost.. thank you!

Answer 1

$how_many = 20;
$counter = 0;
$rows = array();

$result = mysql_query("Your query");
while($row == mysql_fetch_row($result)) {
  $rows[] = $row;
}

$expanded = array();
for($i = 0; $counter < $how_many; $counter++) {
  $expanded[] = $rows[$i];
  $i++;
  if($i == count($rows)) {
    $i = 0;
  }
}

And now $expanded is filled with those 5 rows for 4 times.

Edit: and don’t forget to adjust $i to your start element. For your example that would mean $i = 2 (third element).
