Answer 2

Use this

first of all you get category id on taxonomy page.I suppose one category assign to each post.

   $t_id = $term_id;

Then get value using this

   get_option( "taxonomy_".$t_id );

I want to customize my category section so have use below code and it is working perfectly without any issue..

In

 function.php





add_action ( 'edit_category_form_fields', function( $tag ){
    $cat_title = get_term_meta( $tag->term_id, '_pagetitle', true ); 

    ?>

    <tr class='form-field'>
        <th scope='row'><label for='cat_page_title'><?php _e('Category Page Title'); ?></label></th>
        <td>
            <input type='text' name='cat_title' id='cat_title' value='<?php echo $cat_title ?>'>
            <p class='description'><?php _e('Title for the Category '); ?></p>
        </td>
    </tr> <?php
});
add_action ( 'edited_category', function() {
    if ( isset( $_POST['cat_title'] ) )
        update_term_meta( $_POST['tag_ID'], '_pagetitle', $_POST['cat_title'] );
});

and call in index.php page for fronted

<?php 
                        $categories = get_categories( array(
                            'orderby' => 'name',
                            'order'   => 'ASC'
                        ) );

                        foreach( $categories as $category ) {
                            if($category->name !="Uncategorized")
                            {

                                $cat_title = get_term_meta( $category->term_id, '_pagetitle', true ); 

                                 echo '
                                 <div class="col-md-4"><a href="' . get_category_link($category->term_id) . '">' . $category->name . '</a></div>
                             <div class="col-md-4"><a href="' . get_category_link($category->term_id) . '">' .  $category->description . '</a></div>
                             '; 
                            }

                        } 

                        ?>
