Question

So, what à do is trying to display the 3 first element of an array. Always 3. But, there is not always at least 3 elements.

So, what I’ve done is using an if :

<?php for ($i = 0; $i <= 2; $i++) { ?>
  <?php if($post["Project"]["Post"][$i]){ ?>
    ...
  <?php } ?>
<?php } ?>

But, I keep having “undefined offset” error when there is not 3 entries at least. Anyone with a solution ?

Try the following:

<?php for ($i = 0; $i <= 2; $i++) {
   if(isset($post["Project"]["Post"][$i])){ ?>
   ...
<?php }} ?>
