Hey everyone,
I’m super new to cake and just work through the first tutorial on the main page and cant make the tag sections work. I can add end edit Articles and can also add and Edit Tags but cant set the Tags for the Aricles. I also don’t see changes in the database.
When i go to the Tags website and add or edit the tag i can change the corresponding articles and see this also in the database.
Here probably the 2 important files.
If someone could help me would be so 
.
<!-- File: templates/Articles/add.php -->
<h1>Add Article</h1>
<?php
echo $this->Form->create($article);
// Hard code the user for now.
echo $this->Form->control('user_id', ['type' => 'hidden', 'value' => 1]);
echo $this->Form->control('title');
echo $this->Form->control('body', ['rows' => '9']);
echo $this->Form->control('tags._ids', ['options' => $tags]);
echo $this->Form->button(__('Save Article'));
echo $this->Form->end();
?>
