Question

I’ve got a simple problem that I’m not quite sure how to get around using a loop to grab php variables and add them together

Let’s say I’ve got this loop

$total = 0;
while ( $foo ='bar' );
    $amount = meta($row, 'amount');
endwhile;

$total = 'NEW AMOUNT';

my question is, how do I add amounts (anywhere from 1 to 200) together to create the bottom $total? the amount of objects from while ( $foo ='bar'); is ever growing and can be 2 total objects, or 2000.

Answer 1

add to $total and change the ; in front of the while with : to start that while:

$total = 0;
while ( $foo = 'bar' ):
    $total += meta($row, 'amount'); // assuming `meta()` is one of your functions that extract `amount` from someplace ..
endwhile;

echo $total;
