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
