Question

我正在创建一个热图，显示使用PHP通过API使用KML数据的每个县的计数。表，样式和模板的创建按预期工作。从我的Google云端硬盘查看地图并使用Fusion Tables打开它们时，它们会正确显示。这意味着，地图显示了每个县的不同多边形颜色，具体取决于我通过API创建的计数和存储桶。

但是，我想使用嵌入式iFrame在不同的网页上显示这些地图。根据文档，嵌入使用默认样式。这恰好是我为它创造的那个。

但是，在使用嵌入式地图查看页面时，多边形会显示，但不会根据计数（如果单击多边形显示）进行着色。直到我通过网络界面进入地图，点击发布，颜色才开始出现在嵌入页面上。我还注意到另一种风格正在创建，但它与我已经拥有的相同（下图）。

所以问题是：有没有人遇到过这个问题？有没有办法使用PHP通过API设置发布？任何建议都会有所帮助。

API创建的第一个样式

              ]

                "opacity" => 0.5
              ]
            ]
          ]
        ]
      ]
    ]

Answer 1

After speaking with a Google tech, I found out the iFrame code uses a variable "y" that represents the style id. So in creating a style via the API and receiving the new id, you can then use this in the iFrame code for the map to make sure the right style is assigned.
