Question

I have a field -> tags text,

how do i output all entries tags? without duplicates

eg:
entry1 -  tags: one, two, three
entry2 -  tags: two, five

i want to be able to output all (one, two, three, five) without duplicates

so how do i find this in model/controller and output it to view?

do i use,

key::model()->findAll()   ??

Answer 1

in controller in your action you need to put something like this

$data = key::model()->findAll();
$all = array();
foreach ($data as $d) {
    $all = array_merge($all, explode(', ',$d->tags));
}
$all = array_unique($all);
$this->render('index', array(
    'data' => $all,
));

and in view something like this

echo implode(', ',$data);
