I want to modify the file :\administrator\components\com_k2\views\items\tmpl\default.php  to display the items itemExtraFields value on the back-end items list.

My php code:

<?php foreach ($row->extra_fields as $extraField):?>               <?php if ($extraField->name=="Model No"):?>              <?php echo $extraField->value; ?>         <?php endif; ?>  <?php endforeach; ?>

But it don't work,how should I do ?

Thanks much!
