Question

这是PostsController的图片上传方法

public function store(Request $request, User $user, Image $image)
{
    $this->validate($request, [
        'image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
        'body' => 'required'
    ]);


    if( $request->hasFile('image') ) {
        $image = $request->file('image');
        $filename = time() . '.' . $image->getClientOriginalExtension();

        Image::make($image)->save( public_path('uploads/images/' . $filename ) );
    } 

    $image = $filename;

    auth()->user()->publish(
        new Post(['body' => request('body'), 'image' => $image, 'user_id' => auth()->id()])
    );

    return redirect('/');
}

我想要一种方法来上传图像，视频和音频以及一个用户可以上传图像或视频或音频的输入我如何在一个控制器中完成所有这些工作？

Answer 1

如果您正在使用表单请求，请尝试使用以下代码

  public function rules() {
    $rules = [
        'some_field' => 'required',
    ];

    //  if fileType is audio
    if ($this->input('fileType') == 'audio') {
        $rules['file'] = 'mimes:mp3,mp4';
    }

    //if fileType is video
    if ($this->input('fileType') == 'video') {
         $rules['file'] = 'mimes:mp4,3gp';

    }
    return $rules;
}

字段名称和验证规则会根据您的要求进行更改。

首先确定文件是视频，音频还是图像。然后决定如何验证。希望这会有所帮助。

if( $request->hasFile('file') ) {
		$file = $request->file('file');
		$imagemimes = ['image/png']; //Add more mimes that you want to support
		$videomimes = ['video/mp4']; //Add more mimes that you want to support
		$audiomimes = ['audio/mpeg']; //Add more mimes that you want to support

		if(in_array($file->getMimeType() ,$imagemimes)) {
			$filevalidate = 'required|mimes:jpeg|max:2048';
		}
		//Validate video
		if (in_array($file->getMimeType() ,$videomimes)) {
			$filevalidate = 'required|mimes:mp4';
		}
		//validate audio
		if (in_array($file->getMimeType() ,$audiomimes)) {
			$filevalidate = 'required|mimes:mpeng';
		}		
    }
    $this->validate($request, [
        'file' => $filevalidate,
        'body' => 'required'
    ]);
