本文實例講述了CodeIgniter表單驗證方法。分享給大家供大家參考，具體如下：

1.在D:\CodeIgniter\system\application\views目錄下寫一個視圖文件myform.php

My Form

<?php echo $this->validation->error_string;?>

Username

Password

Password Confirm

Email Address

然后再寫一個視圖文件formsuccess.php

My Form

Your form was successfully submitted!

=anchor('form', 'Try it again!'); ?>

2.在D:\CodeIgniter\system\application\controllers目錄下寫一個控制器文件form.php

class Form extends Controller{

function index(){

$this->load->helper(array('form','url'));

$this->load->library('validation');

$rules['username'] = "required";

$rules['password'] = "required";

$rules['passconf'] = "required";

$rules['email'] = "required";

$this->validation->set_rules($rules);

// $this->validation->set_error_delimiters('

','');

$fields['username'] = 'Username';

$fields['password'] = 'Password';

$fields['passconf'] = 'Password Confirmation';

$fields['email'] = 'Email Address';

$this->validation->set_fields($fields);

if ($this->validation->run()==false) {

$this->load->view('MyView/myform');

}else {

$this->load->view('MyView/formsuccess.php');

}

}

}

?>

3.http://localhost:8888/index.php/form/index訪問一下

Ok，結果都出來了

希望本文所述對大家PHP程序設計有所幫助。
