On my Wordpress website I use a Custom Post (called Tracks and can be seen in the attached code). Within this custom Post are taxonomies (called track_category and can also be seen in the attached code). Although each post could have more than one track category, in reality, each track will only have one taxonomy (either 'Hike', 'Walk', 'Mountain bike' or 'Road bike').

I have created a few posts of type Track. Each post has a different taxonomy ('Hike', 'Walk', 'Mountain bike' and 'Road bike')

The user can edit a track. When a track is edited, I want it that the currently assigned taxonomy would be correctly shown in the dropdown list box (the user could then change the taxonomy).

However, my problem is that when the custom post is edited, the assigned taxonomy is NOT displayed. The first taxonomy type (which is Hike) is always shown.

WHY??!

Code is attached. Any ideas would be very welcome.

<?php



// This line is from the post template

echo do_shortcode('[sut_form alreadysubmitted="' . 1 . '" postid="' . $track_ID . '"]');





// Following code is in the plugin

add_shortcode('sut_form', 'sut_form_shortcode');



function sut_form_shortcode($atts, $content = null) {

    $params = shortcode_atts(array(

        'alreadysubmitted' => false,

        'postid' => '',

    ), $atts );



$sut_postID = $params['postid'];  //$sut_postID is now the ID of the custom post being looked at



// Lot of other code

// Lot of other code



$sut_track_name = get_the_title($sut_postID);

$sut_track_sentence = get_field('sentence', $sut_postID);



$terms = get_the_terms($sut_postID, 'track_category');

$sut_track_category = $terms[0]->name; // Custom post can only have one taxonomy so can select the first



echo sut_get_create_track_form($sut_track_name, $sut_track_sentence, $sut_track_category); // Create form

// PROBLEM --> resulting form does NOT show the taxonomy of the post. It always show the first taxonomy ( = Hike)

}





function sut_get_create_track_form($sut_track_name = '', $sut_track_sentence = '', $sut_track_category = ''){

    $out .= '<form id="create_track_form" method="post" action="" enctype="multipart/form-data">';

    // Other parts of the form

    $out .= '<label for="sut_track_category">Track type</label><br/>';  

    $out .= sut_get_track_categories_dropdown('track_category', $sut_track_category) . '<br/>';
