That’s all. It’s placed in the space where normally my edit.php would be. But the problem obviously is not this piece code, it must be somewhere else.
Hi!
I chose “admin” as the user to which the fields are displayed, but using the administrator account, the fields I setup were never displayed. Therefore I did a little test, trying to print out the §rule array using print_r. Instead of the array’s content, I always get this:
Notice: Undefined variable: rule in [MyPath]\htdocs\wordpress\wp-admin\test.php on line 12
Just tell me, if you need any more infos.
The “§ruleS” was just a spelling mistake in the topic, I did use the original array name in the code.
I did write an own code, but I now used the snippet from the documentation. The exact code is:
add_filter('acf/location/rule_types', 'acf_location_rules_types');
function acf_location_rules_types( $choices )
{
$choices['Basic']['user'] = 'User';
return $choices;
}
add_filter('acf/location/rule_operators', 'acf_location_rules_operators');
function acf_location_rules_operators( $choices )
{
$choices['<'] = 'is less than';
$choices['>'] = 'is greater than';
return $choices;
}
add_filter('acf/location/rule_values/user', 'acf_location_rules_values_user');
function acf_location_rules_values_user( $choices )
{
$users = get_users();
if( $users )
{
foreach( $users as $user )
{
$choices[ $user->data->ID ] = $user->data->display_name;
}
}
return $choices;
}
add_filter('acf/location/rule_match/user', 'acf_location_rules_match_user', 10, 3);
function acf_location_rules_match_user( $match, $rule, $options )
{
$current_user = wp_get_current_user();
$selected_user = (int) $rule['value'];
if($rule['operator'] == "==")
{
$match = ( $current_user->ID == $selected_user );
}
elseif($rule['operator'] == "!=")
{
$match = ( $current_user->ID != $selected_user );
}
return $match;
}
The code is placed at the very bottom of my theme’s functions.php to ensure that it isn’t executed too early.
