Add Filter

Hi,

This argent

I’m trying to add filter to the plugin to make it compatible with pmp plugin.
it shows me this error:
Warning: call_user_func_array() expects parameter 1 to be a valid callback, no array or string given in \wp-content\plugins\if-menu\if-menu.php on line 110

This is line 110 in if-menu.php:
$singleCondition .= call_user_func_array($conditions[$if_conditions[$index]][‘condition’], $params) ? $bit1 : $bit2;

this is my code:

// get the user ID:
$current_user_id = get_current_user_id();
// get the level ID:
$membership_level = pmpro_getMembershipLevelForUser($current_user_id);
//add filter:
add_filter( ‘if_menu_conditions’, ‘f_if_menu’ );
//create the filter function:

function f_if_menu( $conditions ) {

$conditions[] = array(
‘name’ => ‘RG_PH2’, // name of the condition
‘condition’ => function($item) { // callback – must return TRUE or FALSE

//compare between the levels:
if ($membership_level == 1)
return true;
else
return false;
}
);

return $conditions;
}

side note: I’m using localhost as a development environment
