CodeIgniter表单验证方法。具体如下：

1.在D:CodeIgnitersystemapplicationviews目录下写一个视图文件myform.php

<html>

<head>

<title>My Form</title>

</head>

<body>

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

<?php echo form_open('form/index');?>

<h5>Username</h5>

<input type="text" name="username" value="" size="50" />

然后再写一个视图文件formsuccess.php

<html>

<head>

<title>My Form</title>

</head>

<body>

<h3>Your form was successfully submitted!</h3>

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

</body>

</html>

2.在D:CodeIgnitersystemapplicationcontrollers目录下写一个控制器文件form.php

<?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('<div class="error">','</div>');

$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');
