Question

I want to set every first and second tr with a different class. With my code I only get "odd" on every tr. Does anyone knew what is wrong?

 $rowCount = 0;
 if ($rowCount++ % 2 == 1 ) :
     echo "<tr class='even'>";
 else:
     echo "<tr class='odd'>";
 endif;

Answer 1

try this one (keep the $rowCount setting outside the loop):

for($row = 0; $row < $rowTotal; $row++)
{
   echo "<tr class='".($row % 2 ? "even" : "odd")."'>";
}
