Let's talk about how to set the upload directory of the ThinkPHP framework

When using the ThinkPHP framework to upload files, we need to set the directory for uploading files. The directory settings for uploaded files can ensure that uploaded files are stored according to our regulations, making it easier to manage and maintain files.

Let’s introduce how to set the upload directory of the ThinkPHP framework.

1. Settings in the configuration file

In the ThinkPHP framework, the settings for the upload directory can be set in the application's configuration file. Open the application's configuration file (usually config.php or app.php in the config directory), find "file_upload_path" or other corresponding parameters, and modify its value to the upload directory path we want.

For example:

// config.php
return [
    // ...
    'file_upload_path' => './uploads/', // 上传目录设置
    // ...
];

Here the uploaded files are stored in the uploads directory.

2. Settings in the controller

We can also set the upload directory in the controller, so that the storage directory for uploaded files can be dynamically determined.

In the controller that needs to upload files, just set the saving path of the uploaded files. Use the "file" method of the "Request" class that comes with the ThinkPHP framework to obtain the uploaded file, and specify the storage path when saving.

For example:

namespace app\index\controller;

use think\Controller;
use think\Request;

class Upload extends Controller
{
    public function index()
    {
        // 获取上传的图片信息
        $file = Request::instance()->file('image');
        
        // 保存在一个自定义的目录中
        $info = $file->move(ROOT_PATH . 'public' . DS . 'uploads');
        if($info){
            echo $info->getSaveName(); // 输出uploads/a.jpg
        }else{
            echo $file->getError();
        }
    }
}

The pictures uploaded here will be saved in the public/uploads directory.

3. Settings in the model

We can also set the upload directory in the model, so that unified management of uploaded files can be achieved.

Add a method to obtain the upload directory in the model, and call this method to obtain the upload directory each time a file is uploaded. Uploaded files will be stored in this directory.

For example:

namespace app\index\model;

use think\Model;

class Upload extends Model
{
    // 获取上传目录
    public function getUploadDir()
    {
        return './uploads/';
    }
    
    // 上传文件
    public function upload($file)
    {
        $path = $this->getUploadDir();
        // ...
    }
}

When uploading a file, just call the upload method in the model and obtain the upload directory for storage.

Summary

In the ThinkPHP framework, the settings for the upload directory can be set in the configuration file, controller, and model. These settings can realize unified management of the paths of uploaded files, making it easier to manage and maintain uploaded files.
