Question

I have this loop:

<?php foreach ($option['option_value'] as $option_value) { ?>

<?php if ($option_value['quantity'] <= 0) { ?>

What code should be put here?

<?php } ?>

<?php } ?>

<?php echo $i; ?>

Let’s say the loop is 10 rounds. So, when $option_value[‘quantity’] <= 0 I need some variable to count it, and if the condition of $option_value[‘quantity’] <= 0 is met 3 times during those 10 rounds, I want the variable which counts that to have a value of 3, and echo it at the end. So, any help would be appreciated. I’ve tried something with i++ etc. but I don’t know how to define it in order to make it work and count if the condition is met.

Thanks in advance.

You want to initialize $i outside the scope of the foreach loop and then increment it each time the condition is true:

<?php
$i = 0;
foreach ($option['option_value'] as $option_value) {
    if ($option_value['quantity'] <= 0) {
        $i++;
    }
} 
echo $i;
?>
