Question

我是Codeigniter 3的初学者。我试图在视图中提交两个表单值。这是代码：

<?php


class User extends CI_Controller{

    public function __construct(){
        parent::__construct();
        if(!isset($_SESSION['user_logged'])){

             redirect("auth/login","refresh");
        }
    }

    public function profile(){

        $this->load->view('profile');
    }

    public function members(){
        if ($this->input->post('promote')!==FALSE){

            $this->form_validation->set_rules('username','Userpromote','required');

            if($this->form_validation->run() == TRUE){

                $data = array(

                    'subadmin' => $_POST['username']        

                );

                $this->db->insert('sub', $data);

                redirect("user/members", "refresh");
            }

        } elseif ($this->input->post('demote')!==FALSE){

            $this->form_validation->set_rules('subdemote','Userdemote','required');

            if($this->form_validation->run() == TRUE){

                $data2 = $_POST['subdemote'];

                $this->db->delete('sub', array('subadmin' => $data2 ));

                redirect("user/members", "refresh");

            }
        }

        $this->load->view('members');
    }

    public function products(){

        $this->load->view('products');
    }

}

但是问题是，只有“升级”部分有效，而“降级”部分无效。如果我删除“升级”部分，则“降级”存储工作正常。你能告诉我我在做什么错吗？

在我看来，您有一个逻辑问题。您在else if块上有“ demote”代码，这意味着一旦满足if语句，根本就不会达到else if。同样，您在语句末尾使用了重定向，这意味着您将在那一刻被重定向，并且脚本的其余部分将不会执行。如果这样，您可以尝试两个单独的方法：

public function members(){
    if ($this->input->post('promote')!==FALSE){

        $this->form_validation->set_rules('username','Userpromote','required');

        if($this->form_validation->run() == TRUE){

            $data = array(

                'subadmin' => $_POST['username']        

            );

            $this->db->insert('sub', $data);

            //redirect("user/members", "refresh");
        }

    } 
    if ($this->input->post('demote')!==FALSE){

        $this->form_validation->set_rules('subdemote','Userdemote','required');

        if($this->form_validation->run() == TRUE){

            $data2 = $_POST['subdemote'];

            $this->db->delete('sub', array('subadmin' => $data2 ));

            //redirect("user/members", "refresh");

        }
    }

    $this->load->view('members');
}
