Comment simplifier mon menu de sélection de pays PHP/mysql

Question

J'ai un menu de sélection qui affiche les pays. Il regarde la base de données et en juger par la valeur de la db montre l'option sélectionnée. Y at-il un moyen plus simple de faire ce que:

if ($country == 'AG') {echo '<option value="AG" selected="selected">Antigua</option>';} 
else {echo '<option value="AG">Antigua</option>';}; 

if ($country == 'AR') {echo '<option value="AR" selected="selected">Argentina</option>';} 
else {echo '<option value="AR">Argentina</option>';}; 

if ($country == 'AM') {echo '<option value="AM" selected="selected">Armenia</option>';} 
else {echo '<option value="AM">Armenia</option>';}; 

if ($country == 'AW') {echo '<option value="AW" selected="selected">Aruba</option>';} 
else {echo '<option value="AW">Aruba</option>';}; 

if ($country == 'AU') {echo '<option value="AU" selected="selected">Australia</option>';} 
else {echo '<option value="AU">Australia</option >';}; 

if ($country == 'AT') {echo '<option value="AT" selected="selected">Austria</option>';} 
else {echo '<option value="AT">Austria</option>';}; 

if ($country == 'AZ') {echo '<option value="AZ" selected="selected">Azerbaijan</option>';} 
else {echo '<option value="AZ">Azerbaijan</option>';}; 

if ($country == 'BS') {echo '<option value="BS" selected="selected">Bahamas</option>';} 
else {echo '<option value="BS">Bahamas</option>';}; 

if ($country == 'BH') {echo '<option value="BH" selected="selected">Bahrain</option>';} 
else {echo '<option value="BH">Bahrain</option>';}; 

Il y a beaucoup de pays et de faire ce serait de la folie serait-ce pas ????

Answer 1

Chaque fois que vous avez beaucoup de code, qui ne pratiquement le même, il est un signe d'utiliser une boucle ou une fonction au lieu de réécrire les lignes de code de milliers. Michael B. a remarqué que la méthode easies consiste à utiliser un tableau et une simple boucle pour afficher cette liste et marquer l'élément correct comme sélectionné.

$countries = array(
    'us' => 'United States of America', 
    'de' => 'Germany', 
    'pl' => 'Poland', 
    'fr' => 'France', 
    ... 
); 

foreach ($countires as $code => $name) { 
    echo '<option value="' . $code . '" ' . ($country == $code ? 'selected="selected"' : null) . '>' . $name . '</option>'; 
} 

Answer 2

Peut-être quelque chose comme cette volonté fonctionne:

$myCountry = "PL"; 

foreach ($countries as $country) { 
    echo '<option value = "'BH'"' 

    if ($country == $myCountry) {echo ' selected="selected"';} 

    echo '>Bahrain</option>'; 
} 

Où $countries est un tableau ou d'enregistrements avec toutes les données de pays.

Dépend du type de $countries, vous devez remplacer les données de Bahreïn dans l'exemple ci-dessus avec les données provenant de $countries.

Answer 3

Oui, il le ferait, lisez le DRY principle. Itérer à travers votre pays et de resultset vérifier dans la boucle si ce pays est sélectionné, comme ceci:

$selected_value = 'AG'; // set to stored preference or something 
foreach ($countries as $code => $country) { 
    echo '<option value="' . htmlspecialchars($code) . '"'; 
    if ($code == $selected_value) { 
    echo ' selected="selected"'; 
    } 
    echo '>' . htmlspecialchars($country) . '</option>'; 
} 

Answer 4

Quelque chose comme:

$countries = array('AG' => 'Antigua', 'AR' => 'Argentina', ...); 

foreach($countries as $code => $name) { 
    $selected = ($country == $code) ? 'selected="selected"' : ''; 
    echo '<option value="' . $code . '"' . $selected . ' >' . $name . '</option>'; 
} 

Answer 5

Laissez $countries être l'ensemble des pays de la base de données. Que la valeur de pays spécifiée à l'intérieur de variable $country

foreach($countries as $value) 
{ 
    if($country == $value['code']) 
     echo '<option value="' . $value['code'] .'" selected="selected">'. $value['name'] . '</option'; 
    else 
     echo '<option value="' . $value['code'] . '">' . $value['name'] . '</option>'; 
}
