php validation not working - php

Question

I am developing a simple registration form that validates with php. problem is rather than the validation echoing on screen once I click the submit button nothing happens, no error or brake it dose not show me what the error is, I believe my logic is correct but I believe there may be a mistake.
would appriciate any advise or identification of my problem
register.php
<?php
require_once 'core/init.php';
if(Input::exists()) {
$validate = new Validate();
$validation = $validate->check($_POST, array(
'username' => array(
'required' => true,
'min' => 2,
'max' => 20,
'unique' => 'users'
),
'password' => array(
'required' => true,
'min' => 6
),
'password_again' => array(
'required' => true,
'matches' => 'password'
),
'name' => array(
'required' => true,
'min' => 2,
'max' => 50
),
));
if($validation->passed()) {
echo 'Passed';
} else {
print_r($validation->errors());
}
}
?>
<form action="" methord="post">
<div class="field">
<lable for="username">Username</lable>
<input type="text" name="username" id="username" value="<?php echo escape(Input::get('username')); ?>" autocomplete="off">
</div>
<div class="field">
<lable for="password">Choose Your Password</lable>
<input type="password" name="password" id="password">
</div>
<div class="field">
<lable for="password_again">Verify Password</lable>
<input type="password" name="password_again" id="password_again">
</div>
<div class="field">
<lable for="name">Your Name</lable>
<input type="text" name="name" value="<?php echo escape (Input::get('name')); ?>" id="name">
</div>
<input type="submit" value="Register">
</form>
Validation.php
<?php
class Validate {
private $_passed = false,
$_errors = array(),
$_db = null;
public function __contruct() {
$this->_db = DB::getInstance();
}
public function check($source, $items = array()) {
foreach($items as $item => $rules) {
foreach($rules as $rule => $rule_value) {
$value = $source[$item];
if($rule == 'required' && empty($value)) {
$this->addError("{$item} is required")
} else {
}
}
}
if(empty($this->_errors)) {
$this->_passed = true;
}
return $this;
}
private function addError() {
$this->_errors[] = $error;
}
public function errors() {
return $this->_errors;
}
public function passed() {
return $this->_passed;
}
}
UPDATE
Have corrected typo that was correctly pointed out by #PeteR, but there is still a problem that the echo validation is not printing out.

Answer 1

Looks like you have a typo, fella.
if($rule == 'requierd' && empty($value)) {
You also have a semicolon missing here:
$this->addError("{$item} is required");
----^
And another typo:
<form action="" methord="post">
Should be method...
And finally, try this:
private function addError($error) {

Answer 2

Input::exists()
returns false/null or contains errors, thus, the if statement is not true
if(Input::exists()) {
and the code inside of it (validation) does never get executed.
Debug with
print_r(Input::exists());
You should also change your if to a real condition:
if(Input::exists() === true) {
Enable error reporting in PHP (from http://blog.flowl.info/2013/enable-display-php-errors/)
<?php
// Put these lines to the top of your script
error_reporting(E_ALL);
ini_set('display_errors', true);
ini_set('display_startup_errors', true);
ini_set('xmlrpc_errors', true);
Update - Yet another one:
private function addError() {
$this->_errors[] = $error;
}
Method has no parameters..
private function addError($error) {
$this->_errors[] = $error;
}
