Edit Pages

Put this code right above <?php foreach ($pages as $pages_item): ?>:

PHP Code:

echo '<pre>';
print_r($pages);
echo '</pre>';
die(); 


This will output the value of the $pages variable.
Good chance it's empty, and by no means an array. Because your model returns this:

PHP Code:

return $this->db->update('pages', $data); 


I guess the result is either true or false, but not the array with pages your want.

Now that I've put you on the right track, I hope you will solve the rest of the problem on your own. Don't keep asking the same (type of) questions over and over again.
