In my project i want to post some information with multiple images.. All the data has been posted except Files data ..i got only text input values not file value so help me out what i am doing wrong why the images can't be posted??

<form action="" method="post" enctype="multipart/form-data">
 
  <div class="row album-info">
     <div class="col-md-12 album-txt">
       <input type="text" class="form-control" name="title" id="title" placeholder="Untitle Album" required>
     </div>
     <div class="col-md-12 album-txt">
        <input type="text" class="form-control" name="albumLocation" id="album-loc" placeholder="Where were these taken?" required>
     </div>
 </div>
 <div class="row">
   <div id="content">
      <input type="file" name="album[]" id="filer_input2" multiple="multiple" value="test">
    </div>
 </div>
 <div class="col-md-4 col-md-offset-4">
   <button type="submit" class="btn btn-primary btn-block">Create</button>
 </div>
</form>

Controller method:

 public function createalbum(Request $request){
 dd($request->all());

}
