[RESOLVED] foreach array issue

[wintersdance]

I have a image gallery where I am calling up on the script to display 3 images in a row using <td> tags to help organize.

My problem is figuring out how to include the closing </tr> tag. If the row displays 3 images, it closes with the appropriate tag, but if there is less then 3 images in that row, then the closing </tr> tag doesn't work.

Not quite sure what I'm doing wrong with it. Any help in the right direction would be great.

I was thinking maybe I need to add a way to create empty <td> in case there was only 16 images for example and only 5 rows would show correctly with a 6th row only having one image in it.

Suggestions?

     $i=0; 
     foreach ($gallery_array as $row) 
      { 
        if ($i%3==0) // open row
         { 
          echo"<tr>\n"; 
         } 
           $image = $row["gallery_image"];    

           echo "<td><img src=\"".$image."\"></td>\n";
           $i++; 

    if ($i%3==0) // close row, only working if 3 images in a row, is not closing if less then 3 images
     { 
      echo"</tr>\n"; 
     } 
 }

Maybe right after the end of the loop, check the value of $i, and if not 0 then add the closing </tr>?

PS: Ultimately, I like to use fixed-size <div>'s if that's feasible (instead of a table), and then just make them all float left and then fill the available space in the containing element (which should have overflow:auto set in its styling so that it adjusts its height to however those floating div's align themselves.)

Tried different ways of checking for that ending and it seems if I change the operators to anything other than == it either adds the </tr> at the end of each </td> or none at all. I'm probably missing something obvious, just eluding me at the moment.

Your suggestion of the DIV may be a good idea if I can't get this to work right.

To clarify what I was thinking:

<?php
$i = 0;
foreach($gallery_array as $row) {
   if ($i % 3 == 0) // open row
   {
      echo "<tr>\n";
   }
   $image = $row["gallery_image"];
   echo "<td><img src=\"" . $image . "\"></td>\n";
   $i++;
   if ($i % 3 == 0) // close row, only working if 3 images in a row, is not closing if less then 3 images
   {
      echo "</tr>\n";
   }
}
if($i != 0) {      // after the whole loop, cases where closing </tr>
   echo "</tr>\n"; // was not triggered
}

Yep, that did it.

Thanks for your help.
