我在 codeigniter 中创建了一个简单的表单，将 4 个项目插入 mysql。isbn，作者，价格，标题。当我点击提交时，它告诉我 book/book_validation 404 page not found。我尝试了所有我不知道出了什么问题的方法。我的数据库和配置文件都是正确的。

这是我的代码

    <?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Book extends CI_Controller {

    public function index() {

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


    public function book_validation() {

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


        $this->form_validation->set_rules('isbn', 'ISBN', 'required');
        $this->form_validation->set_rules('author', 'Author', 'required');
        $this->form_validation->set_rules('price', 'Price', 'required');
        $this->form_validation->set_rules('title', 'Title', 'required');


        if($this->form_validation->run() == TRUE) {
            echo "Every value has been accepted";
            $this->load->model("model_books");
            $this->insert();
    }



}


        public function insert() {
        $newRow = array("isbn" => $this->input->post('isbn'),
                        "author" => $this->input->post('author'),
                        "price" => $this->input->post('price'),
                        "title" => $this->input->post('title'),

        );

        $this->get_db->insert1($newRow);
        echo "Item added ";

        }









}

?>

        echo "<p> ";

        echo form_close();
    ?>

    <?php

        $this->db->insert("books", $data);

        /*
        if($result) {
            echo $this->db->affected_rows() . "books inserted into database ";
        }

        else {
            echo "Book not added ";
        }
        */
    }

需要修改的函数：

public function insert() {
    $newRow = array("isbn" => $this->input->post('isbn'),
         "author" => $this->input->post('author'),
         "price" => $this->input->post('price'),
         "title" => $this->input->post('title'),
    );

    $this->model_books->insert1($newRow); // NOT get_db, but model_books
    echo "Item added ";

}

其他一切都很好。我测试一下！
