使代码适应我的 mySQL 表
我有一个表“jos_ezrealty”,其中包含地址、城市、州字段以及声明和信息。 delong 表示纬度和经度。我需要调整下面的代码(由 google 提供 - http://code. google.com/apis/maps/articles/phpsqlgeocode.html)来使用我的表。我所有的地址字段都被填满了,我的纬度和纬度的一半都被填满了。长长的田野被填满。我想使用下面的代码来填写缺少的纬度和纬度长信息(不用担心地理编码请求限制,因为我只有 300 个属性,并且此代码仅填充缺失的属性)
谢谢 -

require("phpsqlgeocode_dbinfo.php");

I have a table, "jos_ezrealty" that has address, city, state fields and declat & declong for latitude and longitude. I need to adapt the code below (provided by google - http://code.google.com/apis/maps/articles/phpsqlgeocode.html) to work with my table. All of my address fields are filled, and half of my lat & long fields are filled. I want to use the code below to fill in the missing lat & long information (don't worry about geocoding request limits, as I only have 300 properties and this code only fills in the missing ones)
Thanks -

如果我理解正确,您需要将数据库架构调整为谷歌提供的代码示例。
如果是这种情况,那么如果您的数据库遵循 google 示例,即
您只需将表重命名为
markers
或更改并更改处的
或更改查询以选择您的表。$database
值phpsqlgeocode_dbinfo.php否则请具体说明您的问题。
If I understood correctly you need to adapt your database schema into the code example provided by google.
If that is the case then if your database follows the google example i.e.
You only have to rename your table to
markers
or change and change the$database
value at thephpsqlgeocode_dbinfo.php
or change the queries to select your table.Otherwise please specify your problem.
