Question

请请有人帮助我

$this->load->library('form_validation');
  $this->load->helper('cookie');

  $data = array();


  if($_POST) { 
   // Set validation rules including additional validation for uniqueness
   $this->form_validation->set_rules('yourname', 'Your Name', 'trim|required');
   $this->form_validation->set_rules('youremail', 'Your Email', 'trim|required|valid_email');
   $this->form_validation->set_rules('friendname', 'Friends Name', 'trim|required');
   $this->form_validation->set_rules('friendemail', 'Friends Email', 'trim|required|valid_email');

   // Run the validation and take action
   if($this->form_validation->run()) { 
    echo 'valid;
   }
  }
  else{
   echo 'problem';
  }

表单验证即将返回，没有错误可以让人知道为什么？

Answer 1

它真的回应'有效'吗？（你在那里错过了一个撇号，顺便说一句）

当$ _POST为false时，您显示的代码只会回显'问题'，而不是在验证失败时。不知道更多，它可能很简单：

// Run the validation and take action
if($this->form_validation->run()) { 
 echo('valid');
} else {
 echo('invalid');
}

Answer 2

尝试这样不用检查是否设置了$ _POST - 不是真的需要：

//validation rules here
//
if ($this->form_validation->run() == TRUE) {
     //do whatever that shall be run on succeed
} else {
     $this->load->view('form'); //load the form
}
