Can I add items in the “selection” type field? As when specifying “category”.
Either I choose from the list, or I type the content of the field, which is added to the selectable list.
I tried the “Dynamically populate a select field’s choices” article, but it doesn’t seem to do anything:
function acf_load_editor_field_choices( $field ) {
// reset choices
$field['choices'] = array();
// get the textarea value from options page without any formatting
$choices = get_field('editor', 'option', false);
// explode the value so that each line is a new array piece
$choices = explode("\n", $choices);
// remove any unwanted white space
$choices = array_map('trim', $choices);
// loop through array and add to field 'choices'
if( is_array($choices) ) {
foreach( $choices as $choice ) {
$field['choices'][ $choice ] = $choice;
}
}
// return the field
return $field;
}
Or does this code not do that?
