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
<?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访问一下
Ok，结果都出来了
