I have this error in view,

error message

Code:

A PHP Error was encountered
Severity: Warning
Message: Invalid argument supplied for foreach()
Filename: views/prod_show.php
Line Number: 78

prod_show.php

Code:

<?php
//foreach($query as $row){
foreach($rows as $r):
   echo "<tr>";
   echo "<td>". $r->prod_name ."<br></td>";
   echo "<td>". anchor('prod_c/prod_edit/'.$r->prod_name, 'Edit') ."</td>";
   echo "<td>". anchor('prod_c/prod_delete/'.$r->prod_name, 'Delete') ."</td>";        
   echo "</tr>";
endforeach;        
?&gt;

I don't see aproblem with the foreach, can you see any problem with it?

Thanks in advanced.
