我是 Codeigniter 菜鸟，我正在尝试获取上传图像的文件名，以便将其保存在数据库中。我有两个模型，homemodel 处理我的数据库，image_upload_model 处理图像上传。一切正常，除了我不知道如何将图像文件名发布到数据库

image_upload_model.php

<?php

class Image_upload_model extends CI_Model {

    var $image_path;

    //constructor containing the image path
    function Image_upload_model() {

        $this->image_path = realpath(APPPATH.'../assets/img');
    }

    //uploading the file
    function do_upload() {

        $config = array(
            'allowed_types' => 'jpg|jpeg|gif|png',
            'upload_path' => $this->image_path
        );
        $this->load->library('upload',$config);
        $this->upload->do_upload();
    }
}
?>

homemodel.php

<?php

class homeModel extends CI_Model {

    //inserting into the table tenants
    function addTenants() {

        $this->load->model('Image_upload_model');

        $data = array(
            'Fname' => $this->input->post('Fname'),
            'Lname' => $this->input->post('Lname'),
            'contact' => $this->input->post('contact'),
            'email' => $this->input->post('email'),
            'location' => $this->input->post('location'),
            'img_url' => " "//the filename of the image should go here
        );

        $this->db->insert('tenants', $data);
    }
}
?>

控制器
homecontroller.php

<?php

class HomeController extends CI_Controller {

    public function index() {

        $this->load->helper('form');
        $this->load->helper('html');
        $this->load->model('homemodel');
        $this->load->model('Image_upload_model');

        if ($this->input->post('submit') == 'Submit') {

            $this->homemodel->addTenants();
            echo 'inserted';
            $this->Image_upload_model->do_upload();
            echo 'image uploaded';
        }
        $this->load->view('index.php');
    }
}
?>

任何帮助表示赞赏，谢谢！

你可以得到这样的文件名

  $upload_data = $this->upload->data(); 
  $file_name =   $upload_data['file_name'];

在非常高的层次上，您需要按如下方式重构您的代码：

（1）在你的HomeController，先上传图片（$this->Image_upload_model->do_upload()然后更新你的数据库（$this->homemodel->addTenants()

(2) 在您的上传模型中，您需要调用$this->upload->data()以获取包含您的文件名的信息数组（参见 CodeIgniter 文档）。然后，您必须获取该文件名并将其提供给 HomeController 并将其传递给addTenants函数。

有了这个指导，您应该能够相应地修改您的代码。

轻松获取文件名$this->upload->file_name

基于函数上传system/library/upload.php

public $file_name               = "";
public function data()
{
    return array (
                    'file_name'         => $this->file_name,
                    'file_type'         => $this->file_type,
                    ...
                );
}
