Fix this meta box so that terms get saved WordPress

Grégory Viguier answers:

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

add_action( 'add_meta_boxes', 'my_add_custom_box' );


function my_add_custom_box() {

$post_types = get_post_types( array('_builtin' => false) );
$post_types['post'] = 'post';
$post_types['page'] = 'page';
foreach($post_types as $type) {
add_meta_box(
'myplugin_sectionid',
__( 'My Taxonomy Section Title', 'textdomain' ),
'tags_like_custom_tax',
$type
);
}
}


//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 }

}


//save our custom meta box values
function tags_like_custom_tax_save( $post_id, $post ) {
if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE )
return $post->ID;

if ( isset( $_POST[ "tax_input" ] ) && count( $_POST[ "tax_input" ] ) ) {

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.

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

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
