在 Laravel 中上传多个文件

问题描述

我想一次上传多张图片，但没有成功。

刀片/视图

<form action="{{ url('admin/image/upload') }}" method="POST"enctype="multipart/form-data">
@csrf
    <td><input type="text" name="Fields[0][title]" placeholder="Enter title" class="form-control" /></td>  
    <td><input type="file" name="Fields[0][image]" class="form-control" /></td>
</form>

控制器

$request->validate([
            'Fields.*.title' => 'required|max:25|min:5','Fields.*.image' => 'required',]);
           if($request->hasFile('image'))
            {
            $file=$request->file('image');
            $file_name=hexdec(uniqid());
            $ext=strtolower($file->getClientOriginalExtension());
            $file_full_name=$file_name.'.'.$ext;
            $upload_path='image/';
            $file_url=$upload_path.$file_full_name;
            $success=$file->move($upload_path,$file_full_name);
        $Fields['image']=$file_url;
       foreach ($request->Fields as $key => $value) {
            images::create($value);
        }
     
         return back()->with('success','Image Has Been Saved Successfully.');
}

解决方法

请遵循以下答案：

刀片文件

<form action="{{ url('admin/image/upload') }}" method="POST"enctype="multipart/form-data">
@csrf
    <td><input type="text" name="Fields[]" placeholder="Enter title" class="form-control" multiple /></td>  
    <td><input type="file" name="image[]" class="form-control" multiple /></td>
</form>

控制器

$request->validate([
    'Fields.*' => 'required|max:25|min:5','image.*' => 'required',]);
   if($request->hasFile('image'))
    {
        // dd($request->image) 
foreach ($request->image as $file) {

    dd($file)   
    //get filename with extension
    $filenamewithextension = $file->getClientOriginalName();
    //get filename without extension
    $filename = pathinfo($filenamewithextension,PATHINFO_FILENAME);
    //get file extension
    $extension = $file->getClientOriginalExtension();
    //filename to store
    $filenametostore = $filename . '_' . time() . '.' . $extension;
}

 return back()->with('success','Image Has Been Saved Successfully.');
}
