Displaying images in multiple columns

revez2002

The code below works fine, except for one small thing - it displays all of the images in one row. What I want is to display four images on each row, each in its own column. I have been able to do this with an array from a database search, but I have been unable to figure out how to do this using the list function.

Here is the code that I am currently trying to get working:

  if ($handle = opendir($thumb_folder)) { 
    echo "<tr>\n";
      while (false !== ($file = readdir($handle))) {
        list($img_width, $img_height, $type, $attr) = getimagesize($thumb_folder.$file);
         echo "<td width=\"".($cell * 0.25)."\" align=\"left\" valign=\"middle\">";
         echo "<a class=\"none\" href=\"$target_page.php?section=$section&pid=$pid&tabs=$tabs&picSelected=$file\">";
         echo "<img border=\"0\" height=\"$img_height\" width=\"$img_width\" align=\"absmiddle\" src=\"$thumb_folder/$file\">";
         echo "</a>";
         echo "</td>";
      }
      echo "</tr>\n";
     closedir($handle);				
}

So you need a loop count to trigger new rows after every x images. Search the forums for loop count or loop control to find more than you'll ever need to know.

Thanks for the input Roger.

Yes, I recognize that I need to use a loop or two, but the trick is that I have been unable to figure out where it or they should begin and end with the code that I have right now. For some reason, working the loops in with the list function is throwing ME for a loop :-)

As mentioned in my initial post, I have a working solution for multiple column output of a SQL query, so I will look at that again and see if it triggers an insight.

Cheers,

$count = 0;
$cols = 4;
if ($handle = opendir($thumb_folder)) {
    echo '<tr>';
      while (false !== ($file = readdir($handle))) {
        if ($count == $cols) {
           echo '</tr><tr>';
           $count = 0;
        }
        list($img_width, $img_height, $type, $attr) = getimagesize($thumb_folder.$file);
         echo "<td width=\"".($cell * 0.25)."\" align=\"left\" valign=\"middle\">";
         echo "<a class=\"none\" href=\"$target_page.php?section=$section&pid=$pid&tabs=$tabs&picSelected=$file\">";
         echo "<img border=\"0\" height=\"$img_height\" width=\"$img_width\" align=\"absmiddle\" src=\"$thumb_folder/$file\">";
         echo "</a>";
         echo "</td>";
         $count++;
      }
      echo "</tr>\n";
     closedir($handle);
