First try at OOP->Field checker
Posted: Fri Nov 21, 2008 4:13 am
Hiz.. I have tried creating few sites in the past and I always get stuck with problems, and also that I find my self iterating when it comes to the text fields.. You know those sign-up pages. You gotta check user, pass, name length then pass should be valid, then pas.... yada yada yada.. So I created this class fieldchecker :
I started writing it yesterday.. It is my first shot at OOP. The code really made my work easy. Any suggestions guys? Any amendments I should make? I was thinking of creating another class of mysql, and this should be extended, that way I will be capable of comparing username from database to check whether it already exists... One more question, Is it useful to anybody else besides me :p
Code: Select all
<?php
class fieldschecker
{
// 4-30 min and max email length
// 4-30 min and max username length
// 6-30 min and max password length
// field_error stores every error occured
// breaker is just for the sake of new line in showing errors
public $field_error;
public $yeserror=0;
public $breaker="<br>";
private $maxemaillength=30;
private $minemaillength=4;
private $maxpasswordlength=30;
private $minpasswordlength=6;
private $maxusernamelength=30;
private $minusernamelength=3;
private $maxnamelength=30;
private $minnamelength=2;
private $maxnamelength=30;
private $minlastnamelength=2;
private $mainpassword;// For checking the second confirm password
