I’m trying to populate a select field with all the tags on my posts. However $choices = get_tags(); doesn’t seem to work – but when I use a manual array e.g. $choices = array(“one”, “two”, “three”); this works fine. What’s going on? Thank you 🙂

function acf_load_tag_field_choices( $field ) {

// reset choices
$field[‘choices’] = array();

//gets all tags in the array choices

// $choices = array(“one”, “two”, “three”); this works
$choices = get_tags(); // not working

// loop through array and add to field ‘choices’
if( is_array($choices) ) {

foreach( $choices as $choice ) {

$field[‘choices’][ $choice ] = $choice;

}

}

// return the field
return $field;

}

add_filter(‘acf/load_field/name=tag1’, ‘acf_load_tag_field_choices’);

get_tags() returns an array of term objects

$tags = get_tags();
foreach ($tags as $tag) {
  $choices[$tag->term_id] = $tag->name; 
}
