一，创建自定义的父类控制器

在core目录下创建一个自定义类,以MY_为前缀，如MY_Controller,注意这个前缀不能随意填写，受到config.php中配置的约束，并让MY_Controller继承CI_Controller

<?php
class MY_Controller extends CI_Controller {
    /**
     * 后台登录控制
     * MY_Controller constructor.
     */
    public function __construct()
    {
        parent::__construct();
        $this->load->library("session");
        if (!isset($this->session->user/isLogin)) {
            redirect("login/index");
        }
    }
    public function ajaxReturn($arr) {
		echo json_encode($arr);
		die;
	}
}

二，创建控制器继承自定义父类

<?php
class admin extends My_Controller {
	public function index() {
		$this->load->view("public/title");
		$this->load->view("public/menu");
		$this->load->view("admin");
	}
	public function shopList() {
		$result = $this->db->select("*")->from("shop_list")->get()->result_array();
		$data = [];
		$data["result"] = $result;
		$this->load->view("public/title");
		$this->load->view("public/menu");
		$this->load->view("shopList", $data);
	}
	public function addshop() {
		if ($this->input->post()) {
			$data = [];
			$data["name"] = $this->input->post("name");
			$data["price"] = number_format($this->input->post("price"), 2);
			$data["sb"] = $this->input->post("sb");
			$data["img_url"] = $this->input->post("img_url");
			$data["content"] = htmlspecialchars($this->input->post("content"));
			$data["content2"] = htmlspecialchars($this->input->post("content2"));
			$data["content3"] = htmlspecialchars($this->input->post("content3"));
			$data["create_time"] = date("Y-m-d H:i:s", time());
			$this->db->insert("shop_list", $data);
			$this->ajaxReturn(["status" => 1, "info" => "上传成功"]);
		}
		$this->load->view("public/title");
		$this->load->view("public/menu");
		$this->load->view("shopAdd");
	}
}
