Codeigniter - Working on a "Private message" feature - Sent messages not shown - php

Question

I am setting up a blog from scratch and everything works great. Now I'm working on a "private message" feature. On my messages function in my controller profile.php, it shows all the messages that the user received. This seems to be working perfectly fine.
My view_message function shows the conversation between the user that is currently logged in and the user that he's talking to. I put the user's (who the logged in user is talking to) user ID in the uri segment.
So, $user_from = $this->uri->segment(3)
Here's my code first:
my profile.php controller (view_message function)
public function view_message() {
$data['page_title'] = 'Read Message';
$data['messages'] = $this->model_message->message();
$this->load->view('includes/header', $data);
if ( $data['messages']) {
$this->load->view('profile/view_message', $data);
} else {
$this->load->view('404/main');
}
}
My model_message.php Model:
public function message(){
$uid_to = $this->session->userdata('uid');
$uid_from = $this->uri->segment(3);
$this->db->select('*');
$this->db->from('messages');
$this->db->where('uid_to', $uid_to);
$this->db->where('uid_from', $uid_from);
$this->db->where('receive_delete', 0);
$this->db->join('users', 'users.uid = messages.uid_from');
$this->db->order_by("mid", "desc");
$query = $this->db->get();
$result = $query->result();
return $result;
}
My view_message.php view (I have removed most of the code and only left the basic code to show what I have basically):
<?php foreach ($messages as $message) :
$uid = $this->session->userdata('uid');
<div class="timeline-body-head">
<div class="timeline-body-head-caption">
<a href="javascript:;" class="timeline-body-title font-red-madison">
<?php if ($uid != $message->uid_to) {
echo 'You';
} else {
echo $message->first_name;
} ?>
</a>
<span class="timeline-body-time font-grey-cascade">
<?php echo date("g:i A - F j, Y ", strtotime($message->sent_date)) ?>
</span>
</div>
</div>
<div class="timeline-body-content">
<span class="font-red-cascade">
<?php echo $message->body ?>
</span>
</div>
I'm only able to see the "recieved" messages, not sent. I am not able to figure that out yet. Any help is appreciated. Thank you very much.
