[Solved] incorrect if statement value returned [closed]

by


This condition will fail when it is 0:

!empty ($_POST['interest'])

emtpy() will be true, so !empty() will be false.

All posted values are strings, so to test for a 0 value, you could use for example $_POST['interest'] === '0'. However, that would of course fail for a string like '0.00'
