General login/signup/database coding issues

[impact]

Hello,

I am a beginner in PHP. I would like to know more about optimizing my server side php codes. This is a general post and there may not be a direct answer to this, so I would be thankful for any sort of help on this.

I usually create a
- login.php
- LoginClass.php

Since I do not know to submit a form data directly to a CLASS so I use login.php to get the $_POST data from the form. Once login.php receives the data it then sends the data to LoginClass.php for the actual login processing.

Similarly I usually create
- signup.php
- SignupClass.php

Since LoginClass.php and SignupClass.php needs to access database, I usually have the database codes as private function in each of this CLASS pages.

Is there any better way to do this? for example, using a abstract class and extending to each of these files?

Or how do you usually handle this things in your programming?

Thank you.

Hello,

First off, you can directly pass form data to a script by giving the script URL in the form's

action

attribute.

<form name="someform" cation="action_script.php" methos="post">
...
...
</form>

Secondly, I generally tend to create classes for each object, like, if I have a user I'll create a user class which handles all the user related DB manipulation including login.

hello,

Is there away, I can submit my form data directly to a Class's function or constructor?

Thanks

You can't post directly to a class, you can however do the following:

if(isset($_POST['something']) && !empty($_POST['something'])) {
  // Asign to class here
} else {
  // Error: please select a value
}

You don't have to submit form data to a class in order to access the values in a superglobal because PHP's superglobals [php.net] are always available in all scopes.

As far as a single DB connection, you may want to consider a singleton pattern [webmasterworld.com].
