Gravity Forms 自动完成（+address 字段）

此插件是 Gravity Forms 的附加组件，可启用自动完成字段功能。因此，它会为用户开始键入的字段建议可能的补全。自动完成简化并加快了表单填写过程，并通过查找带有建议的必要数据使您的用户节省时间。

请注意，您可以选择建议的来源。目前它支持多种来源类型： ‘WordPress’、’ URL’、’手动’ 和 ‘地址’。请免费填写以告知我们新的源代码类型，它将在下一个版本中添加。

请在此处查看插件演示： GF Auto Complete 演示

这个怎么运作？

例如，有一个名为 “Test” 的表单，您将向此表单添加一个自动完成字段。您只需将 autocomplete 字段放在表单上。

添加字段后，双击它以显示字段的设置。为“Where to Get Options？”设置选择“手动”，然后将显示新设置“输入数据以进行自动完成”。让我们把一些数据放进去，就像下面的截图一样。

请注意，有一个复选框“允许添加新选项”，勾选它以允许用户为前端的自动完成数据添加新选项。

要在表单设置中保存新字段，只需按“更新表单”按钮即可。之后，新字段将出现在前端。

请注意，新字段具有“无标题”标签，因为这是 Gravity Form 中的默认字段标签。可以在字段的设置中轻松更改它。此外，该表单应添加到一些 wordpress 页面，如上面的示例所示，否则它不会显示在您的网站上。

从哪里获得选项？

使用此设置可设置选项（建议）的来源。请注意，有几种类型的来源：“WordPress”、“URL （json）”和“手动”。下面将逐一描述。

这 “手动” 当需要手动设置选项时（如上面的示例所示），则使用 option 的调用。
这 ‘WordPress’ 选项用于使用不同的 WordPress 来源，例如：用户、页面、帖子、类别等。
这 ‘URL （json）’ 从 url 获取使用 AJAX 自动完成的选项，该 url 以 json 格式返回数据（如：value1、value2、value2 等）。
这 ‘地址’ 获取使用 Google Places Suggest API 进行自动完成的选项。

请查看设置中这些选项的屏幕截图。

如果您选择 “WordPress” 作为选项的来源，则文章标题将在建议列表中使用。请注意：帖子 ID 保存在参赛数据中。如果您想保存另一个 post 属性（例如：post_title、post_name 等或保存自定义 post 字段），可以使用特殊的插件插件来完成。联系我们的支持中心购买该插件。

此外，请查看 JSON 文件的示例：

{“1” ： “值1”， “2” ： “值2”， “值2”， “3”： “值3”， “4” ： “值4”， “5” ： “值5”， “6” ： “值6”， “7” ： “值7”， “值7” ： “值8” ： “值8”}

默认情况下，建议列表包括值：“value1”、“value2”、“value3”等。

如果您想改用键（“1”、“2”、“3”等），请激活“使用 JSON 键作为字段值”选项

如何激活地址自动完成功能？

您需要将建议的来源设置为 ‘Address’。

在某些情况下，可能需要 google browser API 密钥。在这种情况下，请从以下网址获取 google browser API 密钥 http://console.developers.google.com/ 并将其添加到设置

请确保在 Google 中启用以下 API：

检查前端的表单。您的地址字段应转到 Autocomplete（自动完成）。
