这是我的情况:
假设我的radio inputhtml 表单中有一个它的值必须仅存在于表中,如果用户检查其中一个,否则该值必须是zero
这是我的结构:
<div class="inputGroup">
<input id="first_change1" name="first_change" type="radio" value="{{ $game->teamOne->id }}" {{ old('first_change') == $game->teamOne->id ? 'checked="checked"' : '' }} />
<label for="first_change1" class="farsi">{{ $game->teamOne->name }}</label>
</div>
<div class="inputGroup">
<input id="first_change2" name="first_change" type="radio" value="{{ $game->teamTwo->id }}" {{ old('first_change') == $game->teamTwo->id ? 'checked="checked"' : '' }} />
<label for="first_change2" class="farsi">{{ $game->teamTwo->name }}</label>
</div>
<div class="inputGroup">
<input id="first_change3" name="first_change" type="radio" value="0" {{ old('first_change') == "0" ? 'checked="checked"' : '' }} />
<label for="first_change3" class="farsi">None of them</label>
</div>
@if( $errors->has('first_change'))
<h6 class="alert alert-danger farsi text-danger rtl text-right">
{{ $errors->first('first_change') }} <i class="fa fa-2x fa-arrow-up fleft" style="bottom: 5px !important;"></i>
</h6>
@endif
这是我目前对该领域的验证:
'first_change' => 'required|exists:fc_teams,id',
但我需要这样的东西:
'first_change' => 'required|[IF VALUE IS NOT -0-; THEN]exists:fc_teams,id',
