首先，我是新来的，我真的不知道如何使用codeigniter，现在我很困惑。所以我目前正在尝试使用codeigniter向数据库添加数据。当我单击提交按钮时，没有任何内容可以显示，然后我检查了我的数据库并且没有添加任何记录。你们能帮助我吗？
控制器：
<?php

$this->load->model('model_emp');

$this->load->view('getuser',$this->data);

以下是您可以从中获得想法的示例代码，控制器控制您的应用程序逻辑模型执行与数据库相关的操作，并查看您的网页。
控制器：user.php
function registration()
{
$this->load->library('form_validation');
$this->form_validation->set_rules(array(
array(
'field' => 'username',
'label' => 'Username',
'rules' => 'trim|required'
),
array(
'field' => 'password',
'label' => 'Password',
'rules' => 'trim|required'
)
));
if(!$this->form_validation->run())
{
$this->load->view('registration_view');
}
else
{
$this->load->model('user_model');
$user = new users_model();
$user->username = $this->input->post('username');
$user->password = $this->input->post('password');
$user->save();
}
}
查看：registraion_form.php
<form action="<?php echo site_url('user/registration'); ?>" method="post">
<input type="text" name="username" value="<?php echo set_value('username'); ?>" />
<input type="password" name="password" value="<?php echo set_value('password'); ?>" />
<input type="submit" name="submit" value="submit"/>
</form>
型号：user_model.php
public $username;
public $password;
public function save()
{
$data = array(
'username' => $this->username,
'password' => $this->password
);
$this->db->insert('table-name', $data);
}

如果我正确，那会导致你的控制器应该包含视图中的post值。
$username = $this->input->post('Username')
您应该包含所有字段，以便表单验证工作，否则会抛出错误（可能是空白页）。
所以，而不是你对你的模型所做的。它应该看起来像这样，
public function addusers($username, $email, $password, $emp_name, $position, $emp_pic){
$data = array(
'username' => $username ,
'email' => $email ,
'password' => $password,
'emp_name' => $emp_name,
'position' => $position,
'emp_pic' => path_to_your_employee_pic
);
$this->db->insert('employee', $data);
}
使用从控制器传递的参数
$this->model_emp->addusers($username, $email, $password, $emp_name, $position, $emp_pic);
答案 2 :(得分：0)
对控制器中的adduser（）进行一些更改
public function adduser(){
$this->load->library('form_validation');
$this->load->helper('security');
$this->form_validation->set_rules('username','Username','required|min_length[4]|trim|callback_users_exist|xss_clean');
$this->form_validation->set_rules('password','Password','trim|required|min_length[6]|max_length[50]|matches[password_conf]|md5|trim|xss_clean');
$this->form_validation->set_rules('password_conf','Confirmed Password','trim|required|min_length[6]|max_length[50]|matches[password_conf]|md5|trim|xss_clean');
$this->form_validation->set_rules('firstname','Firstname','trim|required|xss_clean');
$this->form_validation->set_rules('middlename','Middlename','trim|required|xss_clean');
$this->form_validation->set_rules('lastname','Lastname','trim|required|xss_clean');
$this->form_validation->set_rules('screenname','Screenname','trim|required|xss_clean');
$this->form_validation->set_rules('gender','Gender','trim|required');
$this->form_validation->set_rules('position','Position','trim|required');
if($this->form_validation->run()){
$this->load->model('model_emp');
$data = array(
'username' =>$this->input->post('Username'),
'password' =>$this->input->post('Password'),
'firstname' =>$this->input->post('Firstname'),
'middlename' =>$this->input->post('Middlename'),
'lastname' =>$this->input->post('Lastname'),
'screenname' =>$this->input->post('Screenname'),
'gender' =>$this->input->post('Gender'),
'position' =>$this->input->post('Position'),
);
$result=$this->model_emp->addusers($data);
if(!$result){
echo mysqli_error($result);
}else{
echo "<div class='alert alert-success alert-dismissable'>
<button type='button' class='close' data-dismiss='alert' aria-hidden='true'>×</button>Successfully Added</div>";
}
}
echo validation_errors("<div class='alert alert-danger alert-dismissable'><button type='button' class='close' data-dismiss='alert' aria-hidden='true'>×</button>","</div>");
}
在模型中将函数更改为
public function addusers($data=null){
if(!empty($data)){
$this->db->insert('table_name',$data);
$ins_id = $this->db->insert_id();
return $ins_id;
} else {
return false;
}
}
