允许路由通过此错误

        <?php } else { ?>
            <h2>That postcode was not recognized</h2>               
        <?php } ?>  

我已经开始你的搜索了。这取决于你去看看为什么你的病情会恶化

我还建议看一下
isset（）
，而不是
if（$var）


总而言之，我的猜测是，
$stores
甚至没有设置或返回false，因此落入
if
语句中的
else
子句中。
看看你的
get\u lat\u long
函数：

$url = "http://maps.google." . $domain . "/maps/geo?q=" . urlencode($postcode) . "&output=json&key=ABQIAAAAd68ReBKRz0DIUqnh0urYdhR0Q3-qVDTU2G-tuQrQTRhYanhS-xTuF2SEKlLS-kmZKBwQN9ukjwTT_A";

现在。我明白了

谷歌
我们很抱歉。。。
。。。但您的计算机或网络可能正在发送自动查询。为了保护我们的用户，我们现在无法处理您的请求

显然，该URL不应该被其他人用作API。谷歌注意到并阻止了你。您必须找到一个API，您实际上可以使用它来获取纬度和经度。
如果
$stores
为false，则会显示“此邮政编码未被识别”一行

这是定义它的行：

$stores = $finder->get_stores_list($_POST['postcode']); 

我将在get_stores_list函数中的查询旁边放置一个
echo
命令，查看查询是否正常，然后在数据库中运行它。你必须把事情的范围缩小一点，以获得社区的更多帮助。
问题

地理编码API v2已于2013年9月9日被拒绝。这个
现在应该使用地理编码API v3

解决方案


我希望这不是您的实际数据库密码。如果是这样的话，请立即在服务器上进行更改。老实说，你最好的选择可能是与整合你的网站的人交谈，或者雇佣一名现场开发人员。因为解决这一问题需要的不仅仅是查看单个文件。需要进行测试（是所有地址阻塞还是部分地址阻塞？），检查数据库是否正在运行且未受损等功能。在文件>选择要扫描的文件目录>扫描字符串“未识别邮政编码”中查找>阅读上面的代码行，找出导致定义此
用户错误的条件，并修复过多的代码。这太模糊，无法在上成功调试。我最好的建议是找一个能花时间在上面的程序员。@JohnMcMahon：比这更糟糕。他们的MySQL服务向互联网公开。
$url = "http://maps.google." . $domain . "/maps/geo?q=" . urlencode($postcode) . "&output=json&key=ABQIAAAAd68ReBKRz0DIUqnh0urYdhR0Q3-qVDTU2G-tuQrQTRhYanhS-xTuF2SEKlLS-kmZKBwQN9ukjwTT_A";

$stores = $finder->get_stores_list($_POST['postcode']);
