<?php class input { public static function exists($type = 'post') { switch($type) { case 'post': return (!empty($_post)) ? true : false; break; case 'get': return (!empty($_get)) ? true : false; break; defult: return false; break; } } public static function get($item) { if(isset($_post[$item])) { //check post data return $_post[$item]; //if available return data } else if(isset($_get[$item])) { return $_get[$item]; //if not return data } return ''; } } ?>and...
<?php class user { private $_db, $_data; public function __construct($user = null) { $this->_db = db::getinstance(); } public function create($fields = array()) { if(!$this->_db->insert('users', $fields)) { throw new exception('there problem when creating account.'); } } public function find($user = null) { //find user id if($user) { $field = (is_numeric($user)) ? 'id' : 'username'; $data = $this->_db->get('users', array($field, '=', $user)); if($data->count()) { $this->_data = $data->first(); return true; } } return false; } public function login($username = null, $password = null) { $user = $this->find($username); print_r($user); return false; } } ?>and...
<?php class validate { private $_passed = false, $_errors = array(), $_db = null; public function __construct() { $this->_db = db::getinstance(); } public function check($source, $items = array()) { foreach($items $item => $rules) { foreach($rules $rule => $rule_value) { $value = trim($source[$item]); $item = escape($item); if($rule === 'required' && empty($value)) { $this->adderror("{$item} required"); } else if(!empty($value)) { switch($rule) { case 'min': if(strlen($value) < $rule_value) { $this->adderror("{$item} must minimum of {$rule_value} characters."); } break; case 'max': if(strlen($value) > $rule_value) { $this->adderror("{$item} must not more {$rule_value} characters."); } break; case 'matches': if($value != $source[$rule_value]) { $this->adderror("{$item} must match {$rule_value}."); } break; case 'unique': $check = $this->_db->get($rule_value, array($item, '=', $value)); if($check->count()) { $this->adderror("{$item} exists. please enter different username."); } break; } } } } if(empty($this->_errors)) { $this->_passed = true; } return $this; } private function adderror($error) { $this->_errors[] = $error; } public function errors() { return $this->_errors; } public function passed() { return $this->_passed; } }
