HTML codes showing in viewpage HTML data

[eluser]mi6crazyheart[/eluser]
I used that "html_entity_decode" but now all the EMBED video codes are getting print rather than the original video. I also tried to use "htmlspecialchars_decode" but it also not doing the same thing(showing the codes but not the original video)

My Controller :

Code:

$this->form_validation->set_rules('CommentMessage', 'Comment', 'htmlspecialchars_decode|trim|required|min_length[2]|max_length[5000]|xss_clean');

My Model :

Code:

$CommentMsg = auto_link(auto_typography($this->input->post('CommentMessage')),'both', TRUE);
$this->db->set('CommentContent', $CommentMsg);
