Quick Start

Let's start :)
Firstly we will load Aauth Library to system


thats OK.

Now we will create 2 new users, Ali and John

$this->aauth->create_user('ali@ali.com','alispass','Ali Akay');
$this->aauth->create_user('john@john.com','johnspass','John Button');

thats it. now we have two users.

Lets Create two group governors and commons :)


Then, Lets Create a User with power whic is Obama (having id=12)

$this->aauth->create_user('obama@usa.gov', 'pass-cia-fbi', 'Barrack Obama');

ok now we have two groups and one user.

Lets create a permissions 'incrase_tax' and 'change_government'


Ok, now lets give accesses. logically 'governors' will have 'increase_tax' permission and 'commons' will have 'change_government' access.
ok lets give proper access with alow_group() function


Ops wait a minute. commons cannot 'increase_tax'. we need to fix it, we will use deny() to take back permission.


Obama also can increse tax ha?


Ok now lets check if commons can 'increase_tax'

    // i dont think so
} else {
   // do sth in the middle

Can Obama increase_tax ? Let's check it.

    // i guess so
} else {
   // piece of code

i think 'increse_tax' must have never been created. just delete it


now better.

So what about public people? (public means not logged users). Can public people travel? Lets assume we have permissions namely 'travel' , of course.


So Admin? what can he do? He can access everthing, You dont need to give permiision ( using allow_group() or allow_user() ) him, he already has.

What about User Variables? for every individual user, variables can be defined as key-value.

this is a simple example to set a variable.


For example if you want to keep users phones

$this->aauth->set_user_var("phone","0216 313 23 33");

to get the variable


Aauth also permits you to define System Variables which can be accesed by every user in the system.


ok lets look at private messages. John (his id=3) will send pm to Ali(id=4)

$this->aauth->send_pm(3,4,'Hi bro. i need you',' can you gimme your credit card?')

sorry John you will be banned :(


Quick Start is done but thats not the end
