Login System - Help me OOPize it!
There is good script by KKeith
http://www.daniweb.com/forums/post951182.html
I want to use it as my base script with some modification. Before I customize it, I want to Make it OOPized into class with functions in functions.php and login+register.phps
Please help me on doing that! I'm intermediate btn newbee and intermediate developer :)
Thanks!
Oh!
Here is the test page I'm using to try do that after I OOPize them

Before I proceed with the main subject of this post, I would like to mention something that I did not have the opportunity to mention in prior posts.
The PHP Programming Innovation Award that happens every month on the PHPClasses site has a new prize that the winners may pick. It is the VS.PHP add-on. This is an add-on that allows you to use Microsoft Visual Studio as IDE for PHP. It was not developed by Microsoft, but rather by JCXSoftware.

</html>1st off - to 'OOP'ize code, you need to
seperate views from the actual code. -->Please explain here what you mean
2nd - Use a database class [Done]
, an application class, and a main class.--> Explain a little, please!
3rd - Try to find a good templating system. I like phptal, and smarty works well too. --> I will check them thanks :)
You also can just include php files that are html with php variables in it, but no logic, like wordpress.--> Please explain
Thanks for your reply, but I need to understand what you are saying. Please explain to me with grain of salt!
seperate views from the actual code. -->Please explain here what you mean
Basically, when you code, you cannot do this:
<?php
// php code here
?>
<html tag="something">
<?php
// More php code
?>You would need to have your logic (PHP) in a file when then returns values which you display in a separate file which also handles the layout/visual stull (HTML)
A template system like Smarty will help you do this as it makes it much harder to just add in random PHP.2nd - Use a database class [Done]
, an application class, and a main class.--> Explain a little, please!
class user would handle ass user functions.
class database would handle database transactions.
You get the idea?
I get it. I see people recommending smarty, but really I see it as mystery. Is there a newbie tutorial? Also back to my question, I see alot of things duplicating themselves in both register.php and login.php. would combining them into function be good idea?
An overview of smarty http://blog.themeforest.net/tutorials/smarty/ .
I like phptal more, and I think it's easier to learn. The handbook / guide on the linked site above provides everything you'll need to use it.
For instance, I'm running http://quiz.codejoust.com/ with this as my index.php file :
<?php
require_once 'phptal.php';
require_once 'Data.class.php';
require_once 'Quizzer.class.php';
header('Content-Type: text/html; charset=utf-8');
$Quizzer = new Quizzer;
$tpl = new PHPTAL('Templates/layout.xhtml');
/** Start Classes **/
$tpl->Quizzer = $Quizzer;
$tpl->action = ucwords($Quizzer->action);
$tpl->loc = $_SERVER['PHP_SELF'];
echo $tpl->execute();
All the logic is in the quizzer class, and I use phptal metal for each page to render an action. The data class is referenced by the quizzer class... and I have a few subclasses in there too (for passing around objects).
I find myself passing around arrays in php, not objects like ruby more because it's a easier way to move information.
In the database class, I have a _construct and a _destruct function, destruct disconnects, and construct checks if there is a static database variable for the class set, if not, it connects to the db.
The methods are such as $this->data->updateQuiz((array) $info) , which are called from the Quizzer class.
I'd use a main layout file, or a header and footer file, including the content in the middle.
What sort of application are you modifying?
I'm Making simple CMS for a site!
I will check that! I need secure Login/Register class. That is why I want to OOPize the one KKeith wrote and learn from there rather than reinverting the wheel.
I'm little busy with work now but when I get little time I will try to mess up with the files to come up with class. Hope Keith will help also:)
