     </select> 

Maintenant, je suis en train de modifier le pays, Say en valeur de la table est stocké au Royaume-Uni pour le Royaume-Uni, puis comment puis-je garder sélectionné le Royaume-Uni en fonction du code du pays dans le tableau. Rédaction Si la condition pour chaque option ne semble pas être une option faisable, je connais la façade Form::select() qui peut faire face à cela facilement, mais sans utiliser Si la condition et la forme Façade est là un moyen d'y parvenir.

Answer 1

<select name="country" id="country" class="form-control"> 
<option value="AF" {{ (isset($user->country)&& $user->country=='AF')?'seected':''}}>Afghanistan</option> 
<option value="AX" {{ (isset($user->country)&& $user->country=='AX')?'seected':''}}>Aland Islands</option> 
<option value="AL" {{ (isset($user->country)&& $user->country=='AL')?'seected':''}}>Albania</option> 
<option value="DZ" {{ (isset($user->country)&& $user->country=='DZ')?'seected':''}}>Algeria</option> 
<option value="AS" {{ (isset($user->country)&& $user->country=='AS')?'seected':''}}>American Samoa</option> 
</select> 

Une meilleure façon est de garder la valeur de l'option dans le tableau

$countryList=[ 
    'AF'=>'Afghanistan', 
    'AX'=>'Aland Islands' 
    ]; 


<select name="country" id="country" class="form-control"> 
@foreach($countryList as $key=>$value) 
    <option value="{{$key}}" {{ (isset($user->country)&&$user->country==$key)?'seected':''}}>{{$value}}</option> 
    </select>

       <option value="AX" {{$customer->country=='AX'?'selected':null}}>Aland Islands</option>
