sprintf help

Hey everyone... I'm trying to edit some code that a friend of mine created. This is to display images for a clients. I'm trying to add a break every 5 images. Here is the link to how it's currently displaying:

code:


<?php 

$roll = "501"; 

?>

I think I need to add something into the sprintf line, but I'm not sure how and/or what. I'm a newbie at this stuff. Thanks in advance.

that code is kindof hard to read... I would suggest a loop kindof like

$image_num = 0;
echo "<tr>";
for($a = 0; $a < $num_images; $a++)
{
   $image_num++;
   if($image_num == 5)
   {
      $image_num = 0;
      echo "</tr><tr>";
   }
   echo "<td><img src='img_path_here'></td>";
}
echo "</tr>";

and may also suggest putting your file_exists loop in a seperate loop that will put the found files into a seperate array, and then display your images based on that.

Is there no way to add a break in this code somewhere...

<?         

$colcount = 0; 

      for ($i=0;$i < 999;$i++){ 

        $photo = $i + 1; 

        if (file_exists("clients/$client/$roll" . "t/" . $roll 

. "_" . sprintf("%04d",$photo) . ".jpg")) { ?>

you'd have to add a </tr><tr> somewhere when your working with tables

if you eliminated the tables and just put the images side by side, you could just insert a <br /> into your code.

the <tr> will add a new row to your table and your images will continue on the next line
