I fixed the Problem.
It was a conflict with “Advanced Custom Fields: ACF Country”
Thanks for letting me know. I guess they use one of our filters but don’t use it the ‘right’ way. Did you notice those plugin authors about the issue?
Hiya
I have the exact same issue with using the ACF country addon and Admin Columns Pro. Looking at their code they are calling a protected function in the plugin file:
add_filter('ac/column/value', [$this, 'admin_column'], 10, 3);
Which calls
protected function admin_column($value, $id, $column)
{
if (
!is_a($column, '\ACA\ACF\Column')
|| $column->get_acf_field_option('type') !== 'country'
) {
return $value;
}
return get_field($column->get_meta_key()) ?? $value;
}
That’s easy enough to change to a public function. It then complains that “Function ACA\ACF\Column::get_acf_field_option is deprecated”. What should be used in its place to get the type of column? I think it’s along the lines of $column->get_setting('type')
But cannot get it to output anything other than the key. If you could please help I’ll happily put a push request into the plugin author to try and get it resolved.
Thanks
Almost as sent that, I managed to get the type using:
$column->get_field()->get_settings()['type']Is this the best way to get it?
If you check for the ACF column, you can get the type by doing this:
if ($column instanceof ACA\ACF\Column) {
$type = $column->get_field_type();
}Brilliant, thank you
You’re welcome. I also noticed that the author of the ACF Country plugin has changed the code in the latest release.
