codeigniter ion_auth admin groups - codeigniter

Hi
is it possible to have more than one group as admin_group? being able to change users?
or, in alternative, how can i add one user to more than one group?
Thanks

The "admin" group is just another named group. There is nothing special about it other than it has a shortcut to check that role with...
$this->ion_auth->is_admin();
instead of just using...
$this->ion_auth->is_group('admin_group');
so really it all depends on how YOU treat the users.
so, to allow 2 groups admin access I'd just do this... Note is_group() can accept an array of strings also.
$admin_groups = array('admin_group1','admin_group2');
if ($this->ion_auth->is_group($admin_groups)) {
//do stuff
}

Laravel menu based on role?

i have codeigniter background. Now, i'm learning about laravel. So, i'm in this condition (Example), I'm trying to create a webapp, which has multiple users. The UsersType A , they can access menu a, menu b & menu c and UsersType B they only can access Menu a.
Now, i'm using https://github.com/lavary/laravel-menu . Well, if it's only have two types , i can write it manually. But, what if there are five types of user or more.
When i'm using codeigniter. I create 4 table Users , UsersType , Menu & MenuAccess. You must be understand how it's work. I just, play it with query then i show it.
UsersType (Users) -> TypeId (UsersType) -> MenuId (MenuAccess) -> MenuId (Menu)
I already use google and I found this https://github.com/Zizaco/entrust but what i can see from that package. It's only give the permission on the action (input,edit & delete)
So, Can i do my codeigniter way in my laravel ? Save my routes properties than show it in my rouotes/web.php (I don't know if it possible, haven't try it yet). sorry for my english.
What I would do is put a function in the User class which checks it's own permission and then returns a view which contains the menu that user has access to.
public function menu()
{
switch($this->role) {
case 'admin':
return view('menus.admin');
[etc]
}
}
Then in the view just check if the user is logged in and show the menu:
#if Auth::check()
{{ Auth::user->menu() }}
#endif
As mentioned in the comments,it sounds like what you want is the ability to conditionally display content based on whether a user has certain permissions.
There's a number of implementations of this. Essentially what they all do is store permissions that can be granted to users, and optionally store roles that allow permissions to be assigned to a role and then users can be given that role, automatically granting them the permissions associated with that role.
I've found spatie/laravel-permission which appears to be quite good. Then, if you pass your user model into the view, you can do something like this:
#if ($user->can('edit-posts'))
<a>Edit post</a>
#endif
That should be flexible enough that it can be reused for different permissions too. If that doesn't do the trick, then it's not hard to roll your own permission system using Laravel's authorization system and you should be able to use the can() method in the same way.

Is it possible to create a user group in Joomla 2.5 that includes everyone that is NOT a member of a particular group?

I have two similar pages that need a menu link. Page 1 is shown to members of Group A. Page 2 is shown to everyone who is not a member of Group A. I have a "Guest" group which would include everyone who is not logged in. But some users are members of group A and Group B. I cannot figure out how to only show one link to them, based on whether they are a member of Group A or not. If I create an access level that includes only Group A and one that includes every other group and someone is in both groups, they will see both links, which is redundant since the pages are different versions of the same page. Any ideas?
We've got a similiar situation, and they way we got around it is to have another Usergroup called "GroupNotA". Then, we have a user plugin that we configure the UserGroups that are in play, and use the OnUserAfterSave event to insure everyone is conditionally in the correct user groups as shown in the code snippets below. With that, we can user menu items, etc. that are available to GroupA and GroupNotA.
myUserPlugin.xml
<field name="usergroup_a" type="usergroup" label="Group A" multiple="false" />
<field name="usergroup_not_a" type="usergroup" label="Group Not A" multiple="false" />
myUserPlugin.php
public function onUserBeforeSave($oldUser, $isnew, $newUser)
{
$UserGroupA = $this->params->get('usergroup_a');
$UserGroupNotA = $this->params->get('usergroup_not_a');
if(in_array(UserGroupA, $newUser['groups'])){
// Use IS in Group A - do nothing?
}else{
// Use is NOT in Group A - Add to group $UserGroupNotA
// add/remove from array $user['groups']
}
A word of caution though, the natural inclination was to use JUserHelper::addUserToGroup(), but it triggers OnUserAfterSave() again, so we went with direct manipulation of the Groups array.
A sample user plugin is installed with Joomla at plugins/user/example.php, and full documentation is available at Plugin/Events/User. Good Luck.
Note I just realized that we do this during a new user registration, so I'm altering the answer to use the event onUserBeforeSave(). I'm not sure that it will work as I originally suggested or not, but at least you have a starting point and the pieces to accomplish a solution.

MediaWiki Groups that override rights from other Groups

I am running a small MediaWiki.
It has the standard groups: all, user, bureaucrat, bot and sysop all with matching rights.
But some of these rights are doubled so "all" may use the writeAPI and "users" may use the writeAPI too, so far no problem.
Now I want to restrict some accounts rights so they can't do anything else than reading.
Therefor I wanted to add a new group, wich overrides all other existing group rights of the account added to it.
So anybody in this group may only read articles no matter what other group they are in.
If you are added to this group it takes rights from you rather than granting you new ones
Is this possible, or do I have to add a new "writingUser" group and add anybody to this new group, remove the all rights from the standard "user" and "all" group and then remove accounts from the "writingUser" group to do the restriction...
I could not find anything like this in the web, were I just looking for the wrong thing or is it just not possible?
Use $wgRevokePermissions, e.g. $wgRevokePermissions['punished-user']['edit'] = false; but you'll have to revoke every permission you don't want them to have explicitly. Also, you might consider simply blocking them:)

Error on login for backend users with custom roles

I created custom role for some users, and I assigned role to particular user with content tree limitation. Like on this image
Problem is that when that user log in, he get error like on this image. Roles are working, so user can see his assigned content tree and work with it.
How can I solved this first screen? Even redirection on his content tree would do the job.
Thank you :)
Make sure that the user you assigned the role to, also has a basic role to access basic contribution functions. I usually have a "backoffice user" role which is assigned to every contributor (or group), which includes (without any limitation) :
user/login on the admin siteaccess
content/read on at least the root node : you need to be able to get "through" that node (and others if needed) to see the ones under it
ezoe, ezjscore, ezmultiupload, ezfind, ezie etc
content/(edit|remove|...) on contents which is owned by the user himself or its group
Hope this helps

Best way to make sure username isn't a reserved word?

Let's say I'm building a web application whose user pages can be found at http://example.com/NAME. What's the best way to make sure the username doesn't conflict with a reserved word (e.g. 'about', 'contact', etc.)? I can think of two ways:
Maintain a list somewhere in my code. This is great and all, but means I have another piece of code I have to edit if I decide to, say, change the "about" page to "aboutus".
Request the URI (e.g. http://example.com/someusername) and check if it exists (doesn't return a 404). This feels kind of like a hack, but on the other hand it does exactly what it's supposed to do. On the other hand, I can't reserve anything without making a page for it.
What would be the best way to go about this? Manual validation of usernames is not an option. Thanks!
EDIT: I forgot to mention, the username has to go at the root, like this:
http://example.com/USERNAME
Not like this:
http://example.com/users/USERNAME
Hence why I'm asking this question. This is for technical reasons, don't ask.
I would strongly suggest using a unique path like http://example.com/users/NAME instead. Otherwise, what are you going to do if you want to add a reserved word, but a user has already taken it as their user name? You'll end up with all kinds of potential migration problems down the track.
Alternatively, if you must have something that goes straight off http://example.com/, could you possibly prefix all user names? So that user jerryjvl would translate to link http://example.com/user_jerryjvl?
If there is really no other possible solution, then I'd say either check user names against whatever data source determines what the 'reserved words' are, or make a lookup file / table / structure somewhere that contains all the reserved words.
In the interest of completeness, if you can't change the routing. Another possibility is to have your user routes and your non-user routes have a programmatic distinction. For example, if you appended a '_' to the end of each of your user routes, then you can make sure that users are located at: http://example.com/NAME_ and the other route would never end in '_'
How about changing your routing scheme so that users are at example.com/users/NAME ?
I maintain the reserved words inside the code.
This is the PERL code that I use in the http://postbit.com/ website to check if the usernamename is a reserved word:
# Black list of logins and sub-domains reserved keywords
my #black_list = qw(
about access account accounts add address adm admin administration
adult advertising affiliate affiliates ajax analytics android anon
anonymous api app apps archive atom auth authentication
...
);
my $username_normalized = lc($username);
$username_normalized =~ s/\W//gs; # 'log-in' -> 'login'
for my $this_username (#black_list) {
if ($username_normalized eq $this_username) {
die("This username is already taken. Please choose other username.\n");
}
}
The complete list of reserved names (like 'css', 'images', 'js', 'admin', 'root', 'old', 'test', 'www', 'admin', 'login', 'devel'...) with more than 300 login usernames is posted here:
http://blog.postbit.com/reserved-username-list.html
You only know what are these 'reserved' words. So better maintain a list and validate against it.
Another method will be if you use a CMS, then all these keywods 'about', 'contact' etc. will be there in your database. Validate against it.
Right next to the text box something like: "Please use your personal nickname or you real name. Usernames with common words indicating affiliation with the site administration may be revoked".
How about just create dummy accounts first with all the reserve words? just list all the possible ones and create them.
if you use
www.example.com/user/name
then there will be no problem but it seems like you'd like the URL to be short.
Maintain a list somewhere in my code. This is great and all, but means I have another piece of code I have to edit if I decide to, say, change the "about" page to "aboutus".
Your menus should be stored in an array/list. This way you would have only 1 piece of code to edit, not 2. =]
Then, since all menus are in one array, you can match username with elements in the array.
for example
$menu = array('About', 'Contact', 'Home')
if( in_array($username, $menu) ) {
echo 'invalid username'
}
You could always look and see how stackoverflow.com works.
