                <div class="box-body">
                  <div class="form-group">
                  <input name='photo' id="file-image" type='file' onchange="readURL(this);" style="visibility:hidden;"/>
                    <p class="help-block">Maksimal ukuran foto 1500 x 1000 pixel</p>
                  <div class="col-sm-6">
                    <img id="image-responsive" class="img-responsive img-bordered-sm" src="{!! url('/').'/protected/public/assets/images/default.png' !!}" height=128 alt="your image"/><br/>
                    <input name="photo2" type="button" id="my-button" class ="btn btn-info" accept=".jpg,.jpeg,.png" value="Pilih Foto">
                    <button type="button" class="btn btn-danger" onclick="hapusGambar()" >Hapus</button>
                  </div>
                  <div class="col-sm-6">
                  <textarea name="photoinput" class="form-control" rows="6" placeholder="Deskripsi">{!! Input::old('photoinput') !!}</textarea>
                  </div>
                </div>
                </div>
                <div class="box-footer">
                  <button type="submit" class="btn btn-info pull-right">Posting</button>
                </div>
                </form>

in route :

Route::get('/timeline/photo', 'ClientTimeLineContr@postPhoto' );

Answer 1

It will not work with GET method:

method="GET"

you should change it for POST. Your route also:

Route::post('/timeline/photo', 'ClientTimeLineContr@postPhoto' );
