Hi guys, 

 

I keep getting error for this function: this is the error: Warning: Division by zero in...../..../rating.php

 

and this is my code tried everything I could think of but no success

 

<?php
include ('db.php');
function getRating($id,$rating,$click){
      $startCount= round($rating/$click);
      $blankCount=5-$startCount;
      $ratingHTML='';
      for($i=0;$i<$startCount;$i++){
          $rate=$i+1;
          $ratingHTML.='<img src="images/star.png" onclick=changeRating("'.$id.'","'.$rate.'")>';
      }

      for($i=$startCount;$i<5;$i++){
          $rate=$i+1;
          $ratingHTML.='<img src="images/white.png" onclick=changeRating("'.$id.'","'.$rate.'")>';
      }
      return $ratingHTML;
}
?>

 

Could you please help m with this? I really appreciate your time in advance.

Make sure you don't call getRating() with a third argument that equals zero. Or edit the function so that it handles the $click==0 case gracefully.

Thanks but it is getting the click from database and I have changed all click fields to 1 so there is nothing equal to zero but still same result.

That doesn't mean $click is not 0 at that point.

I dont understand, this is the code from here http://www.91webless...-rating-script/

Perhaps if you post the context in which this function is being used we can help you further.

Since you seem to be looking for the quick fix for the error, change the line of code to this:

$startCount = (!empty($click)) ? round($rating/$click) : 0;
