Hi!
I’m trying to customize ACF for my purposes by adding custom location rules, but I found out, that with the latest version of ACF, you can’t create Custom Location Rules as described in the documentation. The problem is, that the $rules array is being detected as undefined, even if you use exactly the code, that is provided in the documentation. Does anyone know any solution or approach to this issue?
Thanks in advance,
rjay
Hi @rjay
Thanks for the feedback.
I havent’ experienced this issue before, are you able to post your full code for me to trial?
Also, perhaps it was a spelling mistake while writing the topic, but there is no $rules array, it is $rule.
Thanks

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.
Hi @rjay
Can you please specify what is and isn’t working about the rules?
Thanks

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.
Hi @rjay
Could you post your code that contains the print_r. I don’t understand how the $rule parameter can be undefined…
Thanks
E
<html>
<body>
<h1>The selected value</h1>
<p><?php
print_r($rule);
?>
</p>
</body>
</html>
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 @rjay
Placing this code in your edit.php (not sure where this is used) wont work. You need to debug WITHIN the location rule function.
