Image (php looping) - need help
 
What I am trying to do is pull images/names then put them in a table. I have done this. Now I want it to loop the table 4 times across then drop down
Code:
<tr></tr>
????

With the code I have so far it does 4 then drops the maining down and does not cont to do 4 then drop down until none are left.

Here is the code can anyone help this noob php learner see the prob ?

Code:
<?php
                $n = count($contactlist);
                for ($i=0; $i<$n; $i++) {
                $contact = $contactlist[$i];
                $name = $contact->name;
                $imgurl = $contact->imgurl;
                $uid = $contact->uid;
 
if ($i == 4) {echo '</tr><tr>';}{
           
               
?>
          <td>
          <table border="0">
          <tr>
          <td align="center" class="picture_border">
          <img src="<?php echo htmlentities($imgurl) ?>" /></a></td>
          </tr>
          <tr>
          <td align="center" background="themes/default/images/gradients/003.gif">
          <table width="100%" border="0" cellpadding="4" cellspacing="2" class="text_7_css">
          <tr>
          <td><input type="checkbox" name="uids[]" value="<?php echo $i ?>"/></td>
          </tr>
          <tr>
          <td><?php echo  htmlentities($name, ENT_COMPAT,'UTF-8') ?></td>
          </tr>
          </table>
          </td>
          </tr>
          </table>
          </td>
         
          <?php
         
                  }}
?>
Btw this is not a vbulletin script it does to something else. I have been driving myself crazy on why this won't work lol.

There's many ways of doing something like this. Here are two.

Code:
$counter = 0;
foreach ($contactlist as $contact)
{
      ++$counter;
      // output an image

      if (!$counter % 4)
      {
                // start a new row.
      }
}
Code:
$contactlistrows = array_chunk($contactlist, 4);
foreach ($contactlistrows as $row)
{
      // start row
      foreach ($row as $cell)
      {
                // print cell
      }
      // finish row
}

Great thanks for the replay I will try it out

--------------- Added [DATE]1193633012[/DATE] at [TIME]1193633012[/TIME] ---------------

Now would that code replace code or just add to it ?

--------------- Added [DATE]1193636830[/DATE] at [TIME]1193636830[/TIME] ---------------

I tried just adding the code and it does the samething thing it was. It counts 4 drops down to start another row then just list all them across. It doesn't count again , drop down until number of contacts = 0 .

--------------- Added [DATE]1193637064[/DATE] at [TIME]1193637064[/TIME] ---------------

Again I am just learning lol.

This doesn't pull the images, names and such from a database or a local file, but pulls from a remote location. Maybe that has something to do with it, but I would think it would still be possible to do what I want it

Great!

Thanks for help!

Just had a couple questions to understand a little better

Code:
if (($i>0) && ($i % 4 == 0)) {echo '</tr><tr>';}{
what do && do in php?

and if the % sign multiplying by 4?
