我试图允许用户更改他们的密码,但不是用新密码替换旧密码,而是删除/清除数据库中的密码字段。我只是在测试与数据库的交互,因此我还没有使用模型。

控制器

<?php
class My_account extends CI_Controller {
    public function index(){
        $this->load->view("vChangePassword");
    }

    public function change_password() {

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

        $this->form_validation->set_rules('cur_password','Current Password','required');
        $this->form_validation->set_rules('new_password','New Password','required');
        $this->form_validation->set_rules('con_password','Confirm Password',          'required[matches[new_password]');
        if ($this->form_validation->run()!= true){
            $this->load->view("vChangePassword");
        } else {
            $sql = $this->db->select("*")->from('users')->where('email',$this->session->userdata('email') )->get();
            foreach($sql->result() as $my_info) {
                $db_password = $my_info->password;
                $email = $my_info->email; 
            }
            if(md5($this->input->post('cur_password'))== $db_password){
                $fixed_password = md5($this->input->post('new_password')); 
                $fixed_password ='password';
                $this->db->where('email', $email)->update('users' ,$fixed_password );

                echo "Password has been updated!" ;    
             } else {
                 echo "Password is incorrect!";
             }
        }


    }
}

?>

我的观点

 <?php
echo form_open(base_url()."index.php/my_account/change_password")?>
<?php echo validation_errors();
?>
<table class=”table table-bordered”&gt;
<tbody>
<tr>
<td><small><?php echo 'Old Password:';?></small></td>
<td><?php echo form_password("cur_password");?></td>
</tr>
<tr>
<td><small><?php echo 'New Password:';?></small></td>
<td><?php echo form_password("new_password");?></td>
</tr>
<tr>
<td><small><?php echo 'Confirm Password:';?></small></td>
<td><?php echo form_password("con_password");?></td>
</tr>
</tbody>
</table>
&nbsp;&nbsp;<div id=”some”style=”position:relative;”&gt;<button type=”submit” class=”btn    btn-primary”&gt;<i class=” icon-ok-sign icon-white”&gt;</i>&nbsp;Submit</button>
<?php
echo form_close();
?>

看看这些行:

$fixed_password = md5($this->input->post('new_password'));
$fixed_password ='password';
$this->db->where('email', $email)->update('users' ,$fixed_password );

您为同一个变量分配了 2 个不同的值,其中最后一个是会粘贴的值,即无论用户输入什么,$fixed_password都将具有该值而没有其他值。password其次,查看http://ellislab.com/codeigniter/user-guide/database/active_record.html#update中 CodeIgniter 中 ActiveRecord 类的文档。从中您应该能够弄清楚如何update()正确调用该方法,它将关联数组或对象作为第二个参数。我建议这次使用数组,因为这将是最简单的,而且这似乎就是你要去的地方。希望能帮助到你!

$this->db->where('email', $email)->update('users' ,$fixed_password );

这条线看起来不对。看起来您更新了用户名而不是密码字段。
