我有一个功能，当您搜索邮政编码或机场时，它会在文本框中显示一组结果，如下所示（它应该如何工作）：
这工作正常，直到我在地址搜索中放置一些“随机”的东西，并且由于某种原因，即使搜索列表中没有结果，它仍然会填充下拉菜单（见下文）：
从上面的搜索中，在萤火虫控制台中，我得到以下响应：
No results found, please try a different post code.)
以及以下 XML 响应：
XML Parsing Error: syntax error Location: moz-nullprincipal:{90e67c6c-c3a7-497c-a4df-6045472afde6} Line Number 1, Column 1:
No results found, please try a different post code.
下面是代码：
public static function getAddressByPostcode($postcode) {
$addressArray = array();
$uri = 'http://[ipaddress]:[port]/?pc='.$postcode; // Send to Computer
$response = CurlController::request($uri);
if ($response != false) {
// Clean html
$response = strip_tags($response);
$deserializedAddressArray = unserialize($response);
// Get result set count
self::set_resultcount(count($deserializedAddressArray));
if (self::get_resultcount() > 0) {
foreach ($deserializedAddressArray as $address) {
if(!isset($address['company']) || $address['company'] == '') {
$address['company'] = '';
$addr_cat = 1;
} else {
$addr_cat = 2;
}
if(!isset($address['no'])) $address['no'] = '';
if(!isset($address['street'])) $address['street'] = '';
if(!isset($address['locality'])) $address['locality'] = '';
if(!isset($address['town'])) $address['town'] = '';
if(!isset($address['postcode'])) $address['postcode'] = '';
if(!isset($address['Longitude'])) {
$address['Longitude'] = '';
} else {
$address['Longitude'] = ($address['Longitude'] / 1000) / 3600;
}
if(!isset($address['Latitude'])) {
$address['Latitude'] = '';
} else {
$address['Latitude'] = ($address['Latitude'] / 1000) / 3600;
}
$addressObject = new Address($addr_cat,$address['company'],$address['no'],$address['street'],
$address['locality'],$address['town'],$address['postcode'],
$address['Latitude'],$address['Longitude']);
## Swapped lat and long around as field spec on response is wrong
## TODO - Add validation for address object
// Add address into addresses array
array_push($addressArray,$addressObject);
}
self::getAddressesAsXML($addressArray);
} else {
self::$text_response .= "No results found, please try a different post code. \r\n";
echo self::$text_response;
}
} else {
self::$text_response .= "Address server is taking too long to respond, please try again later. \r\n";
echo self::$text_response;
}
}
如果有人可以帮助我，将不胜感激。我似乎无法弄清楚为什么它填充一个空数组而不显示错误警报消息。
