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: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" /> <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: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>','</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
希望本文所述对大家PHP程序设计有所帮助。
