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
<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> 然后再寫一個視圖文件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目錄下寫一個控制器文件form.php
<?phpclass 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訪問一下
Ok，結果都出來了
