How to fix undefined variable error in Laravel?

Question

I'm trying to running my coding but I got error which is undefined variable.

Here's my controller:

$usr_color = DB::table('listbox')
                ->select('lstbx_codename','lstbx_descname')
                ->where('lstbx_cat', '=', 'usr_prf_color')
                ->orderBy('lstbx_no', 'asc')
                ->get();

Here's my view:

                                        <div class="form-group">
                                            <label>Color</label>
                                            <select name="usr_prf_color" class="form-control">
                                                @foreach ($usr_color as $color) 
                                                    <option value="{{ $color-> lstbx_codename }}" 
                                                        {{ old('usr_prf_color') == $color-> lstbx_codename ? 'selected' : '' }}>
                                                        {{ $color-> lstbx_descname }}
                                                    </option>
                                                @endforeach
    
                                                
                                                --}}
    
                                             </select>
                                        </div>

My error is "Undefined variable: usr_color".

add the specific error and how you are returning the variable from controller to your question. — zahid hasan emon

Are you returning $usr_color in the controller's response? — Brian Lee

You can check that variable before loop

@if(!empty($usr_color))

   // you can loop here

@endif
