我正在使用CodeIgniter 3.1.3构建一个博客，我在管理员中有一项功能可以添加新用户。当我尝试添加新用户时，出现以下错误：
密码字段与confirm_password字段不匹配。
虽然密码和confrom密码字段中的给定密码是相同的。
我无法弄清楚导致问题的原因。
这是我的模特：
public function insert($data){
$this->db->insert('users', $data);
return true;
}
这是我的控制器
public function add(){
//Validation Rules
$this->form_validation->set_rules('first_name','First Name','trim|required');
$this->form_validation->set_rules('last_name','Last Name','trim|required');
$this->form_validation->set_rules('email','Email','trim|required|valid_email');
$this->form_validation->set_rules('username','Username','trim|required|min_length[3]');
$this->form_validation->set_rules('password', 'Password', 'required|matches[confirm_password]');
$data['groups'] = $this->User_model->get_groups();
if($this->form_validation->run() == FALSE){
//Views
$data['main_content'] = 'admin/users/add';
$this->load->view('admin/layouts/main', $data);
} else {
//Create Data Array
$data = array(
'first_name' => $this->input->post('first_name'),
'last_name' => $this->input->post('last_name'),
'username' => $this->input->post('username'),
'password' => md5($this->input->post('password')),
'group_id' => $this->input->post('group'),
'email' => $this->input->post('email')
);
//Table Insert
$this->User_model->insert($data);
//Create Message
$this->session->set_flashdata('user_saved', 'User has been saved');
//Redirect to pages
redirect('admin/users');
}
以下是我的观点：
<div class="row">
<div class="col-lg-12">
<div class="form-group">
<label>First Name</label>
<input class="form-control" type="text" name="first_name" value="<?php echo set_value('first_name'); ?>" placeholder="Enter First Name" />
</div>
<div class="form-group">
<label>Last Name</label>
<input class="form-control" type="text" name="last_name" value="<?php echo set_value('last_name'); ?>" placeholder="Enter Last Name" />
</div>
<div class="form-group">
<label>Email Address</label>
<input class="form-control" type="email" name="email" value="<?php echo set_value('email'); ?>" placeholder="Enter Email" />
</div>
<div class="form-group">
<label>Username</label>
<input class="form-control" type="text" name="username" value="<?php echo set_value('username'); ?>" placeholder="Enter Username" />
</div>
<div class="form-group">
<label>Password</label>
<input class="form-control" type="password" name="password" value="<?php echo set_value('password'); ?>" placeholder="Enter Password" />
</div>
<div class="form-group">
<label>Confirm Password</label>
<input class="form-control" type="password" name="confirm_password" value="<?php echo set_value('confirm_password'); ?>" placeholder="Confirm Password" />
</div>
<div class="form-group">
<label>User Group</label>
<select name="group" class="form-control">
<?php foreach($groups as $group) : ?>
<option value="<?php echo $group->id; ?>"><?php echo $group->name; ?></option>
<?php endforeach; ?>
</select>
</div>
</div><!-- /.row -->

$this->form_validation->set_rules('first_name','First Name','trim|required');
$this->form_validation->set_rules('last_name','Last Name','trim|required');
$this->form_validation->set_rules('email','Email','trim|required|valid_email');
$this->form_validation->set_rules('username','Username','trim|required|min_length[3]');
$this->form_validation->set_rules('password', 'Password', 'required');
$this->form_validation->set_rules('confirm_password', 'Confirm Password', 'required|matches[password]');
将表单验证更改为此并记住在config / autoload.php文件中自动加载表单验证，如$autoload['libraries'] = array('form_validation');。如果它不起作用，请在下面评论。

这是实现这一目标的简洁明了的方法。
这是我的controller代码：
public function add_user(){
$this->form_validation->set_error_delimiters('<p class="text-danger">', '</p>');
if ($this->form_validation->run('register_user_rules') == FALSE){
$this->load->template('user/register');
} else {
$post = $this->input->post();
unset($post['pass_confirm']);
unset($post['submit']);
if($this->UserModel->addUser($post)){
$this->session->set_flashdata('feedback', 'Registration Succesfull! Please Sign in to Continue');
$this->session->set_flashdata('feedback_class', 'alert-success');
} else {
$this->session->set_flashdata('feedback', 'Sorry! Please try again.');
$this->session->set_flashdata('feedback_class', 'alert-danger');
}
return redirect('register');
}
}
现在进行表单验证：
在form_validation.php文件夹中创建一个config文件。
然后在autoload.php文件中写入此行。
$autoload['libraries'] = array('form_validation');
这是我的form_validation.php文件的代码。
<?php
$config = [
'register_user_rules' => [
[
'field' => 'fullname',
'label' => 'Full Name',
'rules' => 'trim|required|max_length[20]'
],
[
'field' => 'email',
'label' => 'Email Address',
'rules' => 'trim|required|valid_email'
],
[
'field' => 'phone',
'label' => 'Phone Number',
'rules' => 'trim|required|numeric|max_length[10]|regex_match[/^[0-9]{10}$/]'
],
[
'field' => 'password',
'label' => 'Password',
'rules' => 'trim|required'
],
[
'field' => 'pass_confirm',
'label' => 'Confirm Password',
'rules' => 'trim|required|matches[password]'
]
]
];
?>
答案 2 :(得分：0)
config / autoload.php：
$autoload['libraries'] = array('form_validation');
查看：
<?php echo form_label('Password:'); ?>
<?php echo form_input(array('placeholder'=>'Enter your password', 'type'=>'password', 'name'=>'password')); ?>
<?php echo form_label('Confirm password:'); ?>
<?php echo form_input(array('placeholder'=>'Confirm your password', 'type'=>'password', 'name'=>'confirm_password')); ?>
控制器：
$this->form_validation->set_rules('password', 'Password', 'required');
$this->form_validation->set_rules('confirm_password', 'Confirm password', 'required|matches[password]');

您必须两次使用设置规则进行两次密码确认
$this->form_validation->set_rules('username','Username','trim|required|min_length[3]|xss_clean');
$this->form_validation->set_rules('password', 'Password', 'required|matches[confirm_password]');

在其中创建表单验证文件
application / config / form_validation.php
编写以下代码
<?php $config = [
'add_user' => [
[
'field' => 'first_name',
'label' => 'First Name',
'rules' => 'trim|required'
],
[
'field' => 'last_name',
'label' => 'Last Name',
'rules' => 'trim|required'
],
[
'field' => 'email',
'label' => 'Email Address',
'rules' => 'required|valid_email'
],
[
'field' => 'username',
'label' => 'Username',
'rules' => 'trim|required|min_length[3]'
],
[
'field' => 'password',
'label' => 'Password',
'rules' => 'required|matches[confirm_password]'
]
]];
控制器代码
function add(){
$this->load->helper('form');
if($this->form_validation->run('add_user')){
$post = $this->input->post();
$_data = array(
'first_name' => $post['first_name'],
'last_name' => $post['last_name'],
'username' => $post['username'],
'password' => md5($post['password']);
'group_id' => $post['group'],
'email' => $post['email']
);
// insert into table
$_insert = $this->User_model->insert($_data);
if($_insert){
// if data is saved show the success message.
$this->session->set_flashdata('user','User has been saved');
} else {
// if failed to save show the failed message.
$this->session->set_flashdata('user','Failed to save the user data');
}
// Redirect to users page
return redirect('admin/users');
} else {
$data['main_content'] = 'admin/users/add';
$this->load->view('admin/layouts/main',$data);
}}
