get_field not loading values

Hello,

when I execute this code

$dossier = get_field('kgk_dossier_2', 'option');

var_dump2($dossier);

I get int(618) as result. ‘kgk_dossier_2’ is a post_tag taxonomy field and 618 is the id of a post_tag, that doesn’t exist in my database.

When I save the field on my Options Page with a Value, the page reloads and the field is empty. Some tags work well, other tags behave like this.

I made a test with my post tag “Ägypten”. It has the id 29.

I selected it:

then I saved it and got this:

get_field returns 618. But when I look it up in my database, there is 29 saved:

Here is the custom-field php code, that generates the field:

if( function_exists('acf_add_local_field_group') ):

acf_add_local_field_group(array (
	'key' => 'group_5734337fc8abf',

I made a litte bug search. And I tried to query the variable manually.

get_field('kgk_dossier_2', 'option')
Output: 618
----
get_option('options_kgk_dossier_2', null);
Output: "29"

I dont get it… :/

ah, before this line in acf’s ‘api-value.php’ in function ‘acf_get_value’ its 29:

$value = apply_filters( "acf/load_value/type={$field['type']}", $value, $post_id, $field );

after that its 618. So I have to check the theme and the plugins I guess. Or is that a known bug?

Sorry for the comment spam.

The filter doesn’t come from a plugin or a theme, it’s a filter from the class acf_field in field.php.

this line in __construct changes my String “29” into a int 618.

$this->add_filter("acf/load_value/type={$this->name}", array($this, 'load_value'), 10, 3);

Its the filter acf/load_value/type=taxonomy

why?

I followed the code a litte bit more.

in ‘api-helpers.php’ in function ‘acf_get_valid_terms’ my value is int(29) before this code:

	// attempt to find new terms
	foreach( $terms as $i => $term_id ) {
		
		$new_term_id = wp_get_split_term($term_id, $taxonomy);
		
		if( $new_term_id ) {
			
			$terms[ $i ] = $new_term_id;
			
		}
		
	}

and int(618) after it. but i still don’t know why..

[edit]
Output of wp_get_split_term(29, 'post_tag') is 618. So i guess my term database table is broken?

“Ägypten” (id: 29) was once a category. I used a plugin to convert the category into a post_tag. My theory is, that wp_get_split_term somehow returns the id of the old category, that doesn’t exist anymore.

But I still don’t know, what to do now :/

I removed the _split_terms row in my options table. That solved the problem. I know that there are no Plugins, that use old term ids, so that is not a problem I hope.
