How to add new function/method.
For example if you want to get email value. Just include the following function inside class User{}
public function get_email($uid)
{
$result = mysql_query("SELECT email FROM users WHERE uid = $uid");
$user_data = mysql_fetch_array($result);
echo $user_data['email'];
}
{
$result = mysql_query("SELECT email FROM users WHERE uid = $uid");
$user_data = mysql_fetch_array($result);
echo $user_data['email'];
}
Print email values.
<?php $user->get_email($uid); ?>
If you're planning to start running a website and you'll be using PHP. You can check the dirrerent web hosting plans online. Some even offer a free domain name.
very helpful, I've been looking for this tutorial for many days, thanks alot!
ReplyDeleteThanks a lot for this topic. It very helped me with my first project=)
ReplyDeleteHi,
ReplyDeleteI just need to say that this is not the real power of PHP OOP.You are using it wrong == Your classes are just collections of methods, and your
public function __construct()
{
$db = new DB_Class();
}
is wrong. NEVER INITIATE db connection in the constructor.
REAL PHP OOP is more complex, and nothing like this.
Right
DeleteGood startup tutorial....
ReplyDeletenice tutorial...keep on sharing...I like it...
ReplyDeleteThat was an excellent code. . .
ReplyDeleteThat was the best code...
ReplyDeleteAnd I want you to implement the crud function.
If you have time please do it ASAP.
Best Wishes,
I love snippets. Love 'em. thanks for this @bentrem
ReplyDeleteha.., I have an error after I test your code on localhost.
ReplyDeleteWhen I access this link: http://localhost/test/PHP_OOP/login.php
I have an error say that: Notice: Undefined index: login in C:\wamp\www\test\PHP_OOP\include\functions.php on line 65
When I log in success: I have an error say like this: Notice: Undefined index: q in C:\wamp\www\test\PHP_OOP\home.php on line 13
Could u help me to solve this problem?
Thanks in advances.
I agree with Anonymous about OOP in PHP syntax is more complex.
ReplyDeleteBut in this article reminds me of when I first created the initial website design with OOP syntax code.
This process, not everyone will understand, but the quality of syntax in a system requires in-depth knowledge about the functions of PHP.
Esta super entendible tu explicacion... Muchas gracias...
ReplyDeleteFabian
Thanks for this great tutorial.
ReplyDeleteThanz mate, well done. I have been try looking for how to combine data which is submited by form and object. This is the very good one.

ReplyDeletei'm using XAMPP 1.7.4 [PHP: 5.3.5]

ReplyDeletethnk u
Following Instructions:
ReplyDeleteNotice: Undefined index: login in C:\Inetpub\wwwroot\atp-software\serial-safe\include\functions.php on line 54
If using downloaded source:
Notice: Undefined index: login in C:\Inetpub\wwwroot\atp-software\serial-safe\include\functions.php on line 65
Please correct code.
A better programmer indents ;)
ReplyDeleteHello every one
ReplyDeletethere is a mistake in ( registration.php ) file please correct u all
when a user will not be login in how the session value will be in memory
remove the following header line
// Checking for user logged in or not
if ($user->get_session())
{
header("location:home.php");
}
because user has to register first then he will be logged in give him chance to register.
Program is very nice and helpful.
Thank you Very Much.
This is a GREAT Beginner Tutorial! Could we have some ADVANCED PHP tutorials using FRAMEWORKS?
ReplyDeleteThank you Brother for this extra-ordinary tech blog!
Thats nice and helpful, but for long time, i'v thinking, whats wrong if we use functions instead of class? i mean, same thing, if we use (echo functionName) instead of (echo $user->functionName), if i am wrong, or my opinion has something wrong, please let me know, i really dont know what to use, for sure for me and others its more easy to use a direct function, but does have something better that function??
ReplyDeleteYou see man, Its a great workout for a bigginer ! There always a stepping stone and surely this was it for me !
ReplyDeleteThanx !
GREAT! stuff Srinivas. I got so very much from your kind sharing.
ReplyDeleteI will share all errors & the solutions that worked for me...
<---IN fixes:
functions.php:
Fatal error: Class 'DB_Class' not found in F:\xampp\htdocs\Randy\include\functions.php on line 10
Fix : line#3: include_once 'config.php' -> include_once 'include/config.php';
Notice: Undefined index: login in F:\xampp\htdocs\Randy\include\functions.php on line 64
Fix : line#64 added an if exists test.. if (isset($_SESSION['login'])){
register.php
Loop : have to comment out line #9 or can't get to register from login page.
Fix : line#9 #header("location:login.php");
home.php
Notice: Undefined index: q in F:\xampp\htdocs\Randy\home.php on line 13
Fix : check using isset.. line#13 if (isset($_GET['q']))
FIN---> fixes
Hi. I have spent a couple of days with this work by Srinivas. Now I converted the code to use MySQLi from the MySQL that is in the original work. This makes for a more overall OOP approach. Also added some more
ReplyDeletefunctionality for retrieving user data.
If you would like to get a set of the files I created they are

Thank you for your valuable posting Srinivas.
Very nice tutorial of OOPS
ReplyDeleteTHERE IS A HUGE MISTAKE HERE. IT DOESN'T WORK.
ReplyDeleteDURING REGISTRATION, IF YOU TRY TO USE mysql_insert_id($connection), it will give error (Notice: Undefined variable: connection...)
There is a problem with the scope.
Kindly rectify and reply on elton2jain{at}gmail.com
It's nice
ReplyDeleteexcelente tutorial
ReplyDeleteFatal error: Class 'User' not found in C:\xampp\htdocs\login.php on line 4 fix me plss this probllem

Hi there,
ReplyDeleteI did not read it all not yet, but finally a COMPLETE (realistic) example which show you how php oop and a database is set up. Thanks a lot!
Very good post. Thanks for that kind of post. Waiting for next.
ReplyDeletemany many thanks....
ReplyDeleteCan you give me an idea to load all the classes for once and wont reload for the next page to save the loading time. I can do it with jquery and PHP but want to do it only with php.
ReplyDeletelogin doesn't working because there is a mistake at check login function in user class and this is a fixed code for that function :
ReplyDeletepublic function check_login($emailusername, $password)
{
$password = md5($password);
$email = $_POST["emailusername"];
$username = $_POST["emailusername"];
$password = $_POST["password"];
$result = mysql_query("SELECT uid from users WHERE email = '$email' or username='$username' and password = '$password'");
$user_data = mysql_fetch_array($result);
$no_rows = mysql_num_rows($result);
if ($no_rows == 1)
{
$_SESSION['login'] = true;
$_SESSION['uid'] = $user_data['uid'];
return TRUE;
}
else
{
return FALSE;
}
}
Dear How can i close the mysql connection basis of this tutorial?
ReplyDeleteThanks
ReplyDeleteNice tutorial :D
ReplyDeleteThis is in response to the "Hi,
ReplyDeleteI just need to say that this is not the real power of PHP OOP. " comment. If you disagree so much with this article being called OOP PHP, then it would be useful and helpful if you could provide a link to something that you consider better or something that could supplement this tutorial.
Nice tutorial, but just saying, no one should use this script on a live site. Or at least filter all database connnections with mysql_real_escape_string and change the md5() to hash() with a better algorithm. Or else your site will get hacked pretty fast.
ReplyDeletebig help to us beginners
ReplyDeleteWell done keep it up

Good Example but not Best
ReplyDeletenice blog.very helpful.but,i am not able to $_SESSION['uid'] in the next page??????????
ReplyDeletenice tutorial man thank u...........
ReplyDeleteNice tutorial i'm learning very much from you !
ReplyDeleteKeep goin' on ! : D
Its really awesome tutorial.. Many thanks..
ReplyDeletevery nice tutorial
ReplyDeleteI second the comments above about this not using OOP to its full advantages (inheritance and polymorphism).
ReplyDeleteAlso, I realize this isn't a security tutorial but to point out just one of vulnerabilities: NEVER concatenate external input in a query. Since you are using MySQL use PDO. Even the mysql_real_escape_string would have been a start (even though it is futile), but prepared statements via PDO is the way to go.
good...
ReplyDeletebut can do more...
With fix it works, thx. Simple but good
ReplyDeleteI have a silly doubt.
ReplyDeleteThe class DB_Class is called everytime a 'User' object is created. and 'User object is created in every page,login,home,registration' . Isn't it weird everytime DB_Class gets called and attempts database connection for every page. Doesn't it slow down the performance?
Or Am I missing out something basically?
very helpfull tutorial i really learned a lot
ReplyDeletegreat
tnx a lot..
ReplyDeleteThanks

ReplyDeletethank god I got u...
ReplyDeletehi,
ReplyDeleteit is really a good tutorial but i am looking for a tutorial in which you tell me about updating(edit) data in the database using oop's concept in php.
i am looking for it for long.hope, you can help me in this regard.
Please, could you explain me, how to add a new function to my class, but this new function must show different datas from my database table, for example:
ReplyDeleteUid --- Name --- Lasname --- Age
01 --- John --- Brown --- 25
02 --- Mery --- White --- 28
public function get_user_profile($uid)
{
$result = mysql_query("SELECT * FROM users WHERE uid = $uid");
$user_data = mysql_fetch_array($result);
.....
}
and use
get_user_profile($uid); ?> or some like that....
but i need only show "age", and in other field show only "Name" for example, but in the same function, becasue in different functions i know do it.
Sorry, but I am a begginer with Object Oriented Programming
Thanksss in advance
Good But Not So easy .....

ReplyDeleteHow to add different user roles? and how to distinguish between them?
That is nice. Petty things like indentation should not worry some people very much. Keep it up!
ReplyDeleteThere I have got following error..
ReplyDeleteFatal error: Class 'DB_Class' not found in "C:\xampp\htdocs\PHP_OOP\include\functions.php on line 10"

very nice code
ReplyDeletethank you! it's very nice.
ReplyDeleteYou should never use query like this: SELECT id FROM users WHERE emai = $email AND password = $password.
ReplyDeleteInstead you should always use query like this: SELECT id, password FROM users WHERE email = $email
and then to use mysql_row or mysql_fetch_array or any other to grad the password and then to compare it with the submitted password.
