tinyUGatMs: Manage users and groups of events in a database

tinyGatMs  package is simple users and groups recurring access time management system.
technolgies used:
-PHP of course
-MySql 
-AJAX(JAVASCRIPT)
-HTML5
-for the css it's minimalist you will see what to do with that

Features:
-Class for groups management(validation, creation, suppression)
-Class for users management(registration, validation, creation, suppression)
-Management area based on user's role, actually it is set on Admin allowed only(fully used of ajax only)
-Users registration with ajax using PDO to connect to MySql
*check of already used mail or already used username (ajax)
*send of validation mail(ajax)
-Users connexion with ajax using PDO to connect to MySql
*check of username existence(ajax)
*check of true password(ajax)
*check of access time (ajax) with message to tell you when to connect if you can't at the moment you try. 
*not register? link
*forget password link
-Users password recovering page  and reset mail sending using ajax
*mail prompt
*password changing after mail validation with unique id
-Management of users
*Edit properties like activation statut,role,password,group for access time etc...
*Add a new user 
*Delete an user
-Management of Groups
*Edit properties like name,description,access time,access time recurrence,starting date to apply the access time, etc...
By default we  make the FIRST GROUP permanent with dayly connexion with 00h-23h59.This is the default group for
all the new users.You can't renamed it with management panel nor delete it  but you could in the database directly
or by building your own query to delete or rename it.However you must modify the name if you do it in all the files that used
it to avoid bug because when you delete a group, all the users belong to this group were sent in FIRST GROUP for not making them loose access to your website.  
*Add a new group
*Delete an existing group.  

Keep in mind that:
the system is minimalist and can be extended like you want...

For the test go to connexion.php  and use one of the two user account already created: zinsou password zinsou or manuel password 0123 

Classes:
-class managemyusers{
					protected $properties,$bdd;
					public function __construct(PDO $bdd,$user,$password,$firstname,$lastname,$email,$groupid,$role,$statutvalidation){
						
					}
					
					public function properties(){
						return $this->properties;
					}
					
					public function add(){
						
							
							INSERT IGNORE INTO users 
							(username,password,mail,dateinscription,groupid,firstname,lastname,role,statutvalidation) 		
							VALUES 
							(:user,:password,:mail,:dateinscription,:groupid,:firstname,:lastname,:role,:statutvalidation) 
							");
						
							echo'User successfully added';
						else
							return false;
						
					}
					
					public function update($oldname){
					
								UPDATE users SET 
								username=:user,password=:password,mail=:mail,dateinscription=:dateinscription,groupid=:groupid,firstname=:firstname,lastname=:lastname,role=:role,statutvalidation=:statutvalidation
								WHERE username=:useroldname');

Functions:
-function inrangetime($x,$y,$z)
*$x,$y,$z are array(hours=>value,minutes=>value,seconds=>value) 
*use inrangetime(array(0,56,56),array(9,56,56),array(23,00,00))
*location ('usefullfunctions.php')
-function dologout()
*location ('usefullfunctions.php')
-function reccurence_reached($x,$y)
*$x (here we use start date for group access time timestamp) but you can use any other timestamp for other purposes.
*$y={'dayly','weekly','monthly','quartely','yearly'} for this $recurrence=array('dayly'=>1,'weekly'=>7,'monthly'=>30,'quartely'=>90,'yearly'=>365);
