Tags are displaying as an ID in posts [closed]

Question

I have been using this plugin so users can in a controlled manner upload their own posts, now it has a category dropdown and I wanted a set list for a tag dropdown where another user kindly helped me out.

The problem I have now is that the tags show as the ID number instead of the name itself.

Example of the post: http://wordpress.art-williams.com/countries/testing-dropdown-tags-21 (it shows 120, experiences at the bottom when it should say "Hotel for example)

I am a novice at wordpress but I can copy + paste :/

The add destination page is here if you need to see it: http://wordpress.art-williams.com/add-destination

Any help is hugely appreciated! I just dont know how to fix that. Here is the code for the tags by the way.

<!-- START TAGS -->
  <?php
    if($this->ucan_options['uCan_Allow_Tags'])
    {
  ?>
      <label>
        <?php echo __('Your Experience', 'ucan-post'); ?>:
        <span class="small"><?php echo __('(What was your travels purpose?)', 'ucan-post'); ?></span>
      </label>


        <?php 


        wp_dropdown_categories(array('taxonomy'=> 'post_tag','exclude'=>6,129,'hide_empty' => 0, 'name' => 'ucan_submission_tags'));
        ?>


  <?php
    }
  ?>
  <!-- END TAGS  -->

Answer 1

To fix the issue, you will need to further alter the plugin. If that works for you, read on.

The wp_dropdown_categories function you are using passes tags via their ID. The plugin requires the values to be in the form of slug. Here is a fix that converts the tag ID to slug.

Replace the following line in ucan-post-class.php:

line 369:   $ucan_new_post['tags_input'] = $this->ucan_options['uCan_Default_Tags'].', '.stripslashes($_POST['ucan_submission_tags']);

With:

$tag = get_term(stripslashes($_POST['ucan_submission_tags']), 'post_tag');
$ucan_new_post['tags_input'] = $this->ucan_options['uCan_Default_Tags'].', ' . $tag->slug;

Keep in mind, this will only allow users to add one tag for each post.

Answer 2

It will take some modification but recently I tried using post_category as one of the arguments for wp_insert_post but every attempt ran unsuccessfully, or made the category a number. This is what I used instead (after the new post is inserted and the ID of the new post is valid in a variable).

if( $insert_post ) {
    wp_set_object_terms( $insert_post, intval( $insert_post['post_category'] ), 'category');
}

Where $insert_post was the same type of array the plugin in question is using in uCan_Display_Publish(). I was only using one category, so I think if you want to do multiple categories, you should use intval() on each item in the post_category array.

In your case, it would most likely be after if ($new_post_id) {

Hope this points you in the right direction!
