PHP/Laravel I can't seem to upload .GIF images -

-

what happens when upload regular images .jpeg, .jpg, .png files, uploads , posts on site nothing wrong. try upload .gif file. site refreshes, empties out input field, , prompts out error message saying field required (say's when input field empty).

my method:

public function upload(requests\createpostsrequest $request)     {         $target_dir = "uploads/";         $target_file = $target_dir . basename($_files['filetoupload']["name"]);         $uploadok = 1;         $findme   = ".";         $pos = strpos($target_file, $findme);         //dd($_post);         $imagefiletype = strtolower(substr($target_file,$pos+1));         if(isset($_post["submit"])) {             $check = getimagesize($_files["filetoupload"]["tmp_name"]);                 //dd($check);             if($check !== false) {                 echo "file image - " . $check["mime"] . ".";                 $uploadok = 1;             } else {                 echo "file not image.";                 $uploadok = 0;             }         }         $filecheck = 0;         $orgfilename = $target_file;         while (file_exists($target_file)) {             $target_file = substr($orgfilename,0,$pos).$filecheck.substr($orgfilename,$pos);             $filecheck++;              $uploadok = 1;         }          if ($_files["filetoupload"]["size"] > 500000) {             echo "sorry, file large.";             $uploadok = 0;         } else if ($_files["filetoupload"]["size"] < 5000) {             echo "sorry, file small.";             $uploadok = 0;         }          if($imagefiletype != "jpg" && $imagefiletype != "png" && $imagefiletype != "jpeg"         && $imagefiletype != "gif" ) {             echo "sorry, jpg, jpeg, png & gif files allowed.";                 echo $imagefiletype;             $uploadok = 0;         }          if ($uploadok == 0) {             echo "sorry, file not uploaded.";          } else {             if (move_uploaded_file($_files["filetoupload"]["tmp_name"], $target_file)) {                 echo "the file ". basename( $_files["filetoupload"]["name"]). " has been uploaded.";                          $post = new posts($request->all());                         $post->filetoupload = $target_file;                         auth::user()->posts()->save($post);                          //$request = request::all();                         //$post = new posts();                         //$post->title = $request['title'];                         //$post->user_id = auth::user()->posts();                         //$post->src = $target_file;                         //$post->save();             } else {                 echo "sorry, there error uploading file.";             }         }         return redirect('');         echo $target_file;     }

and here form:

@if ($errors->any())     <ul class="alert alert-danger">       @foreach ($errors->all() $error)         <li>{{ $error }}</li>       @endforeach     </ul>     @endif         <div class="panel panel-default">             <div class="panel-heading">create post</div>         <div class="panel-body">             {!! form::open(['url' => 'upload', 'enctype' => 'multipart/form-data']) !!}                 <div class="form-group">                 {!! form::label('title', 'title: ') !!}                 {!! form::text('title', null, ['class' => 'form-control']) !!}                 </div>                 <div class="from-group">                 {!! form::label('body', 'select image upload: ') !!}                 {!! form::input('file', 'filetoupload', null, ['class' => 'btn btn-default btn-lg btn-block', 'id' => 'filetoupload']) !!}                 {!! form::submit('upload image', ['class' => 'btn btn-default btn-lg btn-block', 'name' => 'submit', 'accept' => 'image/gif']) !!}                 </div>             {!! form::close() !!}
