使用vue axios和PHP上传多个文件 - 只上传一个文件

Question

我正在尝试使用 vue 和 axios 创建多文件上传。我的问题是只有 ine 文件会上传到服务器。 这是我使用的代码：模板代码

<input type="file" name="images[]" multiple ref="images" @change="handleUpload()">

JS代码

//this is part of the handleUpload() vue method.

let formData = new FormData();

for(let i;i < $refs.images.files.length; i++){
 let file = this.$refs.images.files[i];
 formData.append('image', file);
}

axios.post('/upload', formData, { header: { 'Content-Type': 'multipart/form-data' } })
.then( (response) => console.log(response, response.data) )
.catch( (error) => console.log(error) ); 

PHP 服务器代码

// I'm using slim 4 and sirius upload to manage the file validation/upload
use Psr\Http\Message\ResponseInterface as Response;
use Psr\Http\Message\ServerRequestInterface as Request;
use Psr\Http\Message\UploadedFileInterface;
use Slim\Factory\AppFactory;
use Sirius\Upload\Handler as UploadHandler;

require __DIR__ . '/vendor/autoload.php';

$app = AppFactory::create();

$app->post('/platform/api/v1/compress', function(Request $request, Response $response){

    $uploadHandler = new UploadHandler('/uploads');
    
        $uploadHandler->addRule('extension', ['allowed' => ['jpg', 'jpeg', 'png']]);
   
        $result = $uploadHandler->process( $request->getUploadedFiles() );
        
        // handle single input with single file upload
        if( $result->isValid() ){
            $result->confirm();
                   
            $url = ["master_image_url" => "/uploads/".$result->name];

            $response->getBody()->write(json_encode($url));
        }


    return $response;
});

$app->run();

我如何上传多个文件？也许我需要修改代码？

Answer 1

尝试在append function 中将“图像”更改为“图像[]”

例子：

for(let i;i < $refs.images.files.length; i++){
 let file = this.$refs.images.files[i];
 formData.append('image[]', file);
}

在服务器中

$uploadedFiles=$request->getUploadedFiles();
foreach ($uploadedFiles['image'] as $uploadedFile) {
        if ($uploadedFile->getError() === UPLOAD_ERR_OK) {
           
        }
    }
