本文实例讲述了CodeIgniter表单验证方法。分享给大家供大家参考，具体如下：

1.在D:\CodeIgniter\system\application\views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" />
    <h5>Password</h5>
    <input type="text" name="password" value="" size="50" />
    <h5>Password Confirm</h5>
    <input type="text" name="passconf" value="" size="50" />
    <h5>Email Address</h5>
    <input type="text" name="email" value="" size="50" />
    <div><input type="submit" value="Submit" /></div>
    </form>
    </body>
    </html>

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:\CodeIgniter\system\application\controllers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');
       }
     }
    }
    ?>

3.http://localhost:8888/index.php/form/index访问一下

Ok，结果都出来了
