How do I extract a single variable from this permissions array?

[AndyB]

I would like to extract the viewDeleted value from this $permissions array:

array(6) {

Got it.

    $permissions = XenForo_Visitor::getInstance()->getPermissions();

     foreach ($permissions as $k => $v)
     {
       $array = $v;
       
       foreach ($array as $k => $v)
       {
         if ($k == 'viewDeleted')
         {
           if ($v == false)
           {
             $viewDeleted = 'false';
           }
           if ($v == true)
           {
             $viewDeleted = 'true';
           }
         }
       }
     }

For one, your for loops will fumble and fail. Do not overwrite variables. Secondly, you should google and read up on arrays, because it's completely accessible without a loop:

$array['profilePost']['viewDeleted'];

Thirdly, XenForo has a function to check permissions and if someone has it. I don't know it off the top of my head (class at least), but it's hasPermission();

Hi Jeremy,

Thank you for offering assistance.

This works great!

    $permissions = XenForo_Visitor::getInstance()->getPermissions();
    
     $viewDeleted = $permissions['forum']['viewDeleted'];
    
     if ($viewDeleted == false)
     {
       throw $this->getNoPermissionResponseException();
     }

XenForo_Permissions::has(Content)Permission()

XenForo_Permissions::has(Content)Permission()

Hi tyteen4a03,

How would I use this command to verify if the user has the permission to view deleted posts and threads?

Hi tyteen4a03,

if (XenForo_Permission::hasPermission($userPermissionArray, "profilePosts", "viewDeleted"))

I strongly recommend you to dig into the code - much faster than posting here.

Hi Jeremy,

    $permissions = XenForo_Visitor::getInstance()->getPermissions();
   
     $viewDeleted = $permissions['forum']['viewDeleted'];
   
     if ($viewDeleted == false)
     {
       throw $this->getNoPermissionResponseException();
     }

Since it's a Boolean, your conditional can be simplified:

if(!$viewDeleted)

 

[AndyB]

Thank you, tyteen4a03 and Jeremy for your assistance.

Here is the code I will use:

     $permissions = XenForo_Visitor::getInstance()->getPermissions();
     $viewDeleted = XenForo_Permission::hasPermission($permissions, "forum", "viewDeleted");
  
     if (!$viewDeleted)
     {
       throw $this->getNoPermissionResponseException();
     }

Which is better to use?

$viewDeleted = XenForo_Permission::hasPermission($permissions, "forum", "viewDeleted");

or

$viewDeleted = $permissions['forum']['viewDeleted'];

 

[Daniel Hood]

What about

if (!XenForo_Visitor::getInstance()->hasPermission('forum', 'viewDeleted'))

Lol. So many possible ways.
