Fix this meta box so that terms get saved

I posted the question Use tag interface for hierarchical taxonomy? on Stackexchange. The answer code successfully replaces the metabox, but terms do not save.

So, I have two questions:

1. Can you tell me how to get it to save terms? I'm nearly certain it doesn't work as is, as I've tried it on a blank WP install. Yes, I am changing TAXONOMY_NAME to the taxonomy name.

2. What's the most graceful way to get it to work with multiple post types? add_meta_box and remove_meta_box don't appear to accept arrays for the post type argument.

//remove default metabox

//change TAXONOMY_NAME to your taxonomy name

add_action( 'admin_menu' , 'remove_post_custom_fields' );

function remove_post_custom_fields() {

    remove_meta_box( 'TAXONOMY_NAMEdiv' , 'post' , 'normal' ); 

}





//add our custom meta box

add_action( 'add_meta_boxes', 'my_add_custom_box' );



 function my_add_custom_box() {

    add_meta_box( 

        'myplugin_sectionid',

        __( 'My Taxonomy Section Title', 'textdomain' ),

        'tags_like_custom_tax',

        'post' 

    );

 }



 //call back function to display the metabox

 //change TAXONOMY_NAME to your taxonomy name 

 function tags_like_custom_tax(){

     $tax_name = 'TAXONOMY_NAME';

     global $post;

     $taxonomy = get_taxonomy($tax_name);

     $disabled = !current_user_can($taxonomy->cap->assign_terms) ? 'disabled="disabled"' : '';

     ?>

     <div class="tagsdiv" id="<?php echo $tax_name; ?>">

        <div class="jaxtag">

            <div class="nojs-tags hide-if-js">

                <p><?php echo $taxonomy->labels->add_or_remove_items; ?></p>

                <textarea name="<?php echo "tax_input[$tax_name]"; ?>" rows="3" cols="20" class="the-tags" id="tax-input-<?php echo $tax_name; ?>" <?php echo $disabled; ?>><?php echo get_terms_to_edit( $post->ID, $tax_name ); // textarea_escaped by esc_attr() ?></textarea>

            </div>

            <?php if ( current_user_can($taxonomy->cap->assign_terms) ) { ?>

            <div class="ajaxtag hide-if-no-js">

                <label class="screen-reader-text" for="new-tag-<?php echo $tax_name; ?>"><?php echo $box['title']; ?></label>

                <div class="taghint"><?php echo $taxonomy->labels->add_new_item; ?></div>

                <p><input type="text" id="new-tag-<?php echo $tax_name; ?>" name="newtag[<?php echo $tax_name; ?>]" class="newtag form-input-tip" size="16" autocomplete="off" value="" />

                <input type="button" class="button tagadd" value="<?php esc_attr_e('Add'); ?>" tabindex="3" /></p>

            </div>

            <p class="howto"><?php echo esc_attr( $taxonomy->labels->separate_items_with_commas ); ?></p>

            <?php } ?>

        </div>

        <div class="tagchecklist"></div>

    </div>

          <?php if ( current_user_can($taxonomy->cap->assign_terms) ) { ?>

            <p class="hide-if-no-js"><a href="#titlediv" class="tagcloud-link" id="link-<?php echo $tax_name; ?>"><?php echo $taxonomy->labels->choose_from_most_used; ?></a></p>

          <?php } 

}

How have you registered the taxonomy?

  'issue' --but I tried it with 'category' as well, with the same results. It has no trouble getting/auto-completing other terms from the taxonomy. The only problem is saving.

  I meant other options like enable querying.

1- You don't have a function to save your values, that's the problem : see the last function in my code.
2- See the 2 first functions, I think it's quite elegant : I get all the custom post types in an array, then I add the 'post' and 'page' types, and make a loop with remove_meta_box and add_meta_box.



//remove default metabox



//change TAXONOMY_NAME to your taxonomy name



add_action( 'admin_menu' , 'remove_post_custom_fields' );



function remove_post_custom_fields() {



    $post_types = get_post_types( array('_builtin' => false) );

	$post_types['post'] = 'post';

	$post_types['page'] = 'page';

	foreach($post_types as $type) {

		remove_meta_box( 'TAXONOMY_NAMEdiv' , $type , 'normal' ); 

	}

//add our custom meta box

I'm a bit late in replying and will probably have to repost the question, but wanted to let you know this didn't work on the sites/taxonomies/post types I tested—as with the original code, the new metabox shows up fine and autofills correctly, but new tags are not saved.

Im working on a similar project right now. Im using custom metabox for location/"Ubicacion Colonia" and for services-facilities/"Servicios de la propiedad"

The $_POST, has a structure like this.

["tax_input"]=>
array(4) {
["TAXONOMY_NAME"]=>
string(80) "Term 1,Term 2,Term 4"

You can get the selected terms: $_POST['tax_input']['TAXONOMY_NAME']



<?php

add_action('save_post', 'my_save_postdata', 10, 2);



/**

 * 

 * Save custom post

 * @param integer $post_id

 */

function my_save_postdata( $post_id ) 

{

	if ( !isset($_POST['myplugin_nonce']) ) {

	    return $post_id;

	}

	

    if ( !wp_verify_nonce( $_POST['myplugin_nonce'], 'myplugin_save' ) ) {

		return $post_id;

	}

	

    if ( defined('DOING_AUTOSAVE') && DOING_AUTOSAVE ) {

		return $post_id;

	}

  	

	// Check permissions

	if ( !current_user_can( 'edit_post', $post_id ) ) {

		return $post_id;

	}



    // String with selected terms like "Term1, Term 2"

    $selected = $_POST['tax_input']['TAXONOMY_NAME'];



    // Separate the terms

    $terms = explode(',', $selected);



    // OK, Loop for terms	

    foreach ($terms as $term) {

        // Get the term object based on its name

        $term = get_term_by('name', $term, 'TAXONOMY_NAME');

        // Assign the term to the post

        wp_set_object_terms( $post->ID, $term->slug, $term->taxonomy );

    }



} // end function
