反馈页面在 codeigniter 中没有响应
Feedback page not responding in codeigniter
我正在尝试在用户登录后提交反馈。如果表单留空,则数据不会被插入到数据库中,也不会显示任何消息。
这是我的控制器:
function dashboard(){
$this->load->model('stud_model');
$this->form_validation->set_rules('name','Name', 'required');
$this->form_validation->set_rules('email', 'Email Id', 'required');
$this->form_validation->set_rules('feedback', 'Feedback', 'required');
$data['username'] = $this->session->userdata('username');
if ($this->form_validation->run()) {
$data = array(
'Name' => $this->input->post('name'),
'Email' => $this->input->post('email'),
'Feedback' => $this->input->post('feedback'),
);
$submit = $this->stud_model->insert_feedback($data);
if($submit) {
$this->session->set_flashdata('message', 'Feedback Successfully Submitted !');
redirect('Students/enter');
}else{
$this->session->set_flashdata('message', 'Feedback could not be Submitted !');
redirect('Students/enter');
}
}else{$this->load->View('dashboard', $data);}
}
function enter(){
if ($this->session->userdata('username') != '') {
$data['username'] = $this->session->userdata('username');
$this->load->View('dashboard', $data);
}else{
redirect('Students/log');
}
}
function logout(){
$this->session->unset_userdata('username');
redirect('Students/index');
}
这是我的观点:
<body>
<h1 align="center">My Dashboard</h1><br><br>
<h3 align="left">Welcome <?php echo $username ?> !</h3>
<form action="http://localhost/ci/index.php/Students/dashboard" align="center">
<?php echo validation_errors(); ?>
<br>
<input type="hidden" name="name" value="<?php echo $username ?>"><br>
Email Id : <br><input type="text" name="email"><br><br>
Feedback:<br><br>
<textarea name="feedback" rows="10" cols="50"></textarea><br><br>
<input type="submit" value="Submit"><br><br>
<?php echo $this->session->flashdata("message"); ?>
<a href="<?php echo base_url().'index.php/Students/logout'; ?>">Logout</a>
</form>
</body>
这是我的模特:
function insert_feedback($data){
$this->load->database();
$this->db->insert("feedback", $data);
return $this->db->insert_id();
}
我想你用
$this->load->library('database');
改为
$this->load->database();
Change setting on config folder in autoload.php
$autoload['libraries'] = array('database','form_validation', 'session');
$autoload['helper'] = array('url','form');
我自己遇到了错误。
我忘记在我的表格中添加 'method="post"'。
