Question

I’m trying to find the number of input boxes that aren’t empty, but I’m getting a value of 1 every time. what am I doing wrong?

foreach( $_POST as $key=> $value ) {
    if ($value!='' && $key!='add') {
        $count =  count($value);
    }  
}
echo $count;

Answer 1

You’re simply redefining the $count variable to be count($value) (which is always 1 since $value is not an array), not incrementing it.

Use the increment operator instead to add 1 to $count when appropriate:

$count ++;

You’re also probably better using empty(..) for your checks, like so:

$count = 0;
foreach($_POST as $key => $value)
{
    if($key != 'add' && !empty($value))
    {
        $count++;
    }
}
echo $count;
