我在php中有一个带有foreach的JSON解码数组，每次从这个下拉列表中选择一个选项时，它都会在表单中包含一个select选项，它会返回列表中的最后一个值。我试图保存平面数字，构建，解决1个变量。我该怎么做？
$api_url = 'http://rest.api?postcode=' . urlencode($_GET['postcode']);
$api_json = file_get_contents($api_url);
$api_array = json_decode($api_json, true);
$address = $api_array['addresses'];
foreach($address as $addresses){
echo '<option>'.$addresses['address'].'</option>';
$flatnumber = $addresses['flatNumber'];
$address1 = $addresses['building'];
$address2 = $addresses['address1'];
$town = $addresses['town'];
$county = $addresses['county'];
}
这是数组：

答案 0 :(得分：0)
我所做的是将所有值放入选项值，提交表单然后在提交后展开值。
$result = $_POST['address1'];
$result_explode = explode('|', $result);
$flatnumber = $result_explode[0];
$building = $result_explode[1];
$street = $result_explode[2];
<form method="post">
<select name="address1">
foreach($address as $addresses){
echo '<option value="'.$addresses['flatNumber'].'|'.$addresses['building'].'|'.$addresses['address1'].'|'.$addresses['knownElectricityMeter'].'|'.$addresses['knownGasMeter'].'">'.$addresses['flatNumber'].' '.$addresses['building'].' '.$addresses['address1'].'</option>';
}
</select>
</form>
