Answer 1

Add
protected $fillable = ['name'];
under your Category class.
And use
Category::create($request->only(['name']));
instead of $request->all() which tries to write to categories._token column inside your Category model combined with create().

Answer 2

You should try this:
<a class="btn btn-primary pull-right navbar-right" data-toggle="modal" href="#category">Add Category</a>
<div class="modal fade" id="category">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title">Add New</h4>
</div>
{!! Form::open(['route' => 'category.store', 'method' => 'post']) !!}
{!! csrf_field() !!}
<div class="modal-body">
<div class="form-group">
{{ Form::label('name', 'Title') }}
{{ Form::text('name', null, array('class' => 'form-control')) }}
</div>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="submit" class="btn btn-primary">Save changes</button>
</div>
{!! Form::close() !!}
</div><!-- /.modal-content -->
</div><!-- /.modal-dialog -->
</div><!-- /.modal -->

Answer 3

you can also add
protected $guarded = [];
to your model and then you can use mass assignment.
