Answer 1

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">' . $category->name . '</div>
<div class="col-md-4">' . $category->description . '</div>
';
}
}
?>
