Is there a way to combine these two functions? Category System

Hi, I'm working on a blog in which I need to display the categories it has, the problem is not that I can not get them, the problem is that I have to select the two values(category.id and category.title) in my add view , basically I have two inputs and I'm trying to get them together in just one single select input.

Here is my functions, one for selecting the ID of the category, and a second one for the category's name.

PHP Code:

    // Select Category ID
            $subject_options = array();
            $subject_options[0] = 'Select Post Category ID';

            $subject_list = $this->Posts_categories_model->get_list();
            
            foreach($subject_list as $subject){
                $subject_options[$subject->id] = $subject->title;                                
            }

            $data['subject_options'] = $subject_options;
            
    // Select Category Name
            $subject_name_options = array();
            $subject_name_options[0] = 'Select Post Category Name';

            $subject_name_list = $this->Posts_categories_model->get_list();

            foreach ($subject_name_list as $subject_name) {
                $subject_name_options[$subject_name->title] = $subject_name->title;
            }

            $data['subject_name_options'] = $subject_name_options; 


Here is my method get_list located in the Post_categories_model:

PHP Code:

   public function get_list()
    {
        $query = $this->db->get($this->table);
        return $query->result();
    } 


This is what I have in my add view:

PHP Code:

   <!-- Post Subject ID -->
    <div class="form-group">
        <?= form_label('Post Category', 'subject_id'); ?>
        <?= form_dropdown('subject_id',$subject_options,0, array('class' => 'form-control')); ?>
    </div>
    
    <!-- Post Subject Name -->
    <div class="form-group">
        <?= form_label('Post Category Name', 'subject_name'); ?>
        <?= form_dropdown('subject_name',$subject_name_options,0, array('class' => 'form-control')); ?>
    </div> 


and there's another problem, when displaying the category name in my post view(index.php; see below), I have this:

PHP Code:

<i class="fa fa-folder-open"></i> <a href="<?= base_url(); ?>posts/category/<?= $page->subject_id; ?>"><?= $page->subject_name; ?></a> 


it seems pretty simple but what can I do if there's more than one category per post?

I hope you guys can help me.

By the way this is what I have in my controller to display the posts:

PHP Code:

   public function index()
    {
        // Get Posts
        $data['posts'] = $this->Post_model->get_featured();
        // Get Post Categories
        $data['categories'] = $this->Post_model->get_categories();
                
        // Load template
        $this->template->load('public', 'default', 'posts/index', $data);
    }

Combining is easy:

PHP Code:

if( $subject_list = $this->Posts_categories_model->get_list() )
{
    foreach( $subject_list as $sub )
    {
        $data['subject_options'][$sub->id]         = $sub->title;
        $data['subject_name_options'][$sub->title] = $sub->title; 
    }
}

{

    {
        $data['subject_options'][$sub->id]         = $sub->title;
        $data['subject_name_options'][$sub->title] = $sub->title; 
    }
} 


If I do that I just get them repated, the difference between them is the value would "value=1" or value="category-one".
Not just that I' trying to add them here(the first two lines):

PHP Code:

           $data = array(
                'subject_id'    => $this->input->post('subject_id'),
// Obviously the input below will not work but I had to try it out.
                'subject_name'    => $this->input->post($sub->title),
                'slug'            => $slug,
                'title'            => $this->input->post('title'),
                'post_image'    => $post_image,
                'body'            => $this->input->post('body'),
                'is_published'    => $this->input->post('is_published'),
            ); 


Doing it as you say it would just fill the subject_id input, and I want one input to fill the two values.
How can I fill in the second value(subject_name) according to the subject_id?

I was merely combining the code you had in the first section. I was not trying to solve any problems. It is my perception that you may need to learn a little more PHP, and that perhaps you jumped on the CodeIgniter bandwagon a little early. Whatever the case, your learning experience is now, when you figure it out.

Yes, I know but the combination was not the problem, I could do that by myself with my own example just like:

PHP Code:

           $subject_options = array();
            $subject_name_options = array();
            $subject_options[0] = 'Select Post Category ID';
            $subject_name_options[0] = 'Select Post Category Name';

            $subject_list = $this->Posts_categories_model->get_list();
            
            foreach($subject_list as $subject){
                $subject_options[$subject->id] = $subject->title;
                $subject_name_options[$subject->title] = $subject->title;                                
            }

            $data['subject_options'] = $subject_options;
            $data['subject_name_options'] = $subject_name_options; 


which is what I had before asking but I decided to divided them into two fuctions to make more clear what I was asking for. The problem of what I really want is to create a tag system like Wordpress in which the only necessary action is to select the cat/tag and it shows the link and its corresponding name in the front-end(per post)... Thats what I'm really having troubles with. I think WordPress call it "get term by id" or something like that.
