panel only visible to admins

monstr · January 2008

hejhej.
is it possible to have the panel on the comments page only displayed when you are logged in as a admin?

Hi, I see two ways to do it, I'll give you the cleanest:
create a new theme and put a conditional statement around the code of panel.php (some code is stolen from appg/init_vanilla.php)

// this code is not tested
$DisplayPanel = false;
if ( $Context->SelfUrl == "comments.php"  )
{
	if ($Context->Session->UserID > 0) {
		$RequiredPermissions = array('PERMISSION_CHECK_FOR_UPDATES',
			'PERMISSION_APPROVE_APPLICANTS',
			'PERMISSION_MANAGE_REGISTRATION',
			'PERMISSION_ADD_ROLES',
			'PERMISSION_EDIT_ROLES',
			'PERMISSION_REMOVE_ROLES',
			'PERMISSION_ADD_CATEGORIES',
			'PERMISSION_EDIT_CATEGORIES',
			'PERMISSION_REMOVE_CATEGORIES',
			'PERMISSION_SORT_CATEGORIES',
			'PERMISSION_CHANGE_APPLICATION_SETTINGS',
			'PERMISSION_MANAGE_EXTENSIONS',
			'PERMISSION_MANAGE_LANGUAGE',
			'PERMISSION_MANAGE_STYLES',
			'PERMISSION_MANAGE_THEMES');
	
		$RequiredPermissionsCount = count($RequiredPermissions);
		$i = 0;
		for ($i = 0; $i < $RequiredPermissionsCount; $i++) {
			if ($Context->Session->User->Permission($RequiredPermissions[$i])) {
				$DisplayPanel = true;
				break;
			}
		}
	}
}
if ( ! $Context->SelfUrl == "comments.php" OR $DisplayPanel )
{
	// old code in panel.php
}

This should always display the panel on other pages than somments.php, and if we're in comments.php, display the panel only if we are authenticated and have a permission among those listed.

woh, thanks so far, looks quite good but doesn't work ._.
i get a php error because of the following lines

if ( $Context->SelfUrl == "comments.php" )

if ( ! $Context->SelfUrl == "comments.php" OR $DisplayPanel )

i tried

if (in_array($Context->SelfUrl, array("comments.php"))

but it didn't work. any idea?

sorry (i wasn't even right, shame on me) here it is:

Notice: Undefined variable: Context in /kunden/121606_86830/monstrs/forum/themes/monstrs/panel.php on line 4

I think "$Context" needs to be changed to "$this->Context" (the theme patch is being called from within the Panel object).

Also, wouldn't this be easier?

// this code is not tested

if ( ! $this->Context->SelfUrl == "comments.php" OR $this->Context->Session->User->RoleID > {whatever} )
{
// old code in panel.php
}

Sounds like timfire is on the money with the $this-> thing. I'm too tired to think about the other bit.

Grahack · January 2008

Must work now, Tim is right. Now for the precise condition, I first started to think like the last bit of code, but I'm not good at permissions and role ids and so on. I just copy-pasted the code in appg/init_vanilla.php to be sure to have something like an 'admin condition'. It depends on what Monstr wants.
