【问题描述】：

我已经拥有后端和前端页面库的控制器、模型和视图。但不知何故，我的前端库无法连接，同时，我的后端已经可以连接到数据库并像 crud 一样运行。我不知道我哪里出错了，谁能帮帮我？

控制器：galleryweb.php

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

class Galleryweb extends CI_Controller 

    public function __construct()
    
        parent::__construct();
        $this->load->model("galleryweb_model");
        $this->load->library('form_validation');
    

    public function index()
    
        $data["gallery"] = $this->galleryweb_model->getAll();
        $this->load->view("front/gallery", $data);
    

模型：Galleryweb_model.php

class Galleryweb_model extends CI_Model


    function __construct()
        parent::__construct();
    
    private $_table = "gallery";

    public $id_gallery;
    public $name;
    public $image;

    public function rules()
    
        return [
            ['field' => 'name',
            'label' => 'Name',
            'rules' => 'required']
        ];
    

    public function getAll()
    
        return $this->db->get($this->_table)->result();
    

    public function getById($id)
    
        return $this->db->get_where($this->_table, ["id_gallery" => $id])->row();
    

    public function save()
    
        $post = $this->input->post();
        $this->id_gallery = uniqid();
        $this->name = $post["name"];
        $this->image = $this->_uploadImage();
        $this->db->insert($this->_table, $this);
    

    public function update()
    
        $post = $this->input->post();
        $this->id_gallery = $post["id"];
        $this->name = $post["name"];
        if (!empty($_FILES["image"]["name"])) 
            $this->image = $this->_uploadImage();
         else 
            $this->image = $post["old_image"];
        
        $this->db->update($this->_table, $this, array('id_gallery' => $post['id']));
    

    public function delete($id)
    
        $this->_deleteImage($id);
        return $this->db->delete($this->_table, array("id_gallery" => $id));
    

    private function _uploadImage()
    
        $config['upload_path']          = './upload/galery/';
        $config['allowed_types']        = 'gif|jpg|png|jpeg';
        $config['upload_max_filesize']  = '100000M';
        $config['post_max_size']        = '100000M';
        $config['file_name']            = basename($_FILES["image"]["name"]);
        $config['overwrite']            = true;

        $this->load->library('upload', $config);

        if ($this->upload->do_upload('image')) 
            return $this->upload->data("file_name");
        
    

    private function _deleteImage($id)
    
        $gallery = $this->getById($id);
        if ($gallery->image != "default.jpg") 
            $filename = explode(".", $gallery->image)[0];
            return array_map('unlink', glob(FCPATH."upload/galery/$filename.*"));
        
    

查看：前面：gallery.php

<div class="container-fluid">
            <div class="col-md-4 thumb">
                <?php foreach ($gallery as $gallery): ?>
                <a class="fancybox" href="<?php echo $gallery->name ?>" data-fancybox-group="gallery"> 
                    <img class="img-polaroid" src="<?php echo base_url('upload/galery/'.$gallery->image) ?>"  /> 
                </a>
                <?php?>
            </div> 
            <nav aria-label="Page navigation example ">
                <center>
                    <ul class="pagination align-center">
                        <li class="page-item">
                            <a class="page-link" href="#" aria-label="Previous">
                                <span aria-hidden="true">&laquo;</span>
                                <span class="sr-only">Previous</span>
                            </a>
                        </li>
                        <li class="page-item"><a class="page-link" href="#">1</a></li>
                        <li class="page-item"><a class="page-link" href="#">2</a></li>
                        <li class="page-item"><a class="page-link" href="#">3</a></li>
                        <li class="page-item"> 
                            <a class="page-link" href="#" aria-label="Next">
                                <span aria-hidden="true">&raquo;</span>
                                <span class="sr-only">Next</span>
                            </a>
                        </li>
                    </ul>
                </center>
            </nav>
    </div>

【问题讨论】：

您的问题过于宽泛且不具体。你到底有什么问题？您只是在问如何将数据从控制器传递到视图吗？然后你应该阅读 CI 的文档。如果这不是您要问的，那么您需要澄清您的问题。

我没听懂你想说什么。你在找 $this->load->view('name');

【参考方案1】：

$this->load->model("gallery_model"); 但型号名称是 Galleryweb_model？

【讨论】：

我已经把它改成了galleryweb_model，但它仍然出现这样的错误：遇到未捕获的异常类型：ParseError 消息：语法错误，文件意外结束文件名：C:\xampp\htdocs\eat\application \views\front\gallery.php 行号：261 回溯：文件：C:\xampp\htdocs\eat\application\controllers\galleryweb.php 行：16 功能：查看文件：C:\xampp\htdocs\eat\index .php 行：315 功能：require_once
