WordPress表单插件 Contact form 7介绍及拓展高级功能实现和部分表单框架样式

什么是 Contact form 7？

首先  Contact form 7 插件是一款免费的 WordPress 表单插件，用于给访客填写表单、收集信息功能。利用配合 MailChimp（国外邮件营销工具）亦可实现邮件订阅功能，由于 Contact Form7 插件的强大，也可以实现自动给用户发送邮件（可包含文件附件），配合 Contact Form CFDB7 插件可记录用户表单填写信息 (Contact form 7 插件默认是不会保存这些内容的，它只会发送邮件发给你)；配合Redirection for Contact Form 7  插件也实现用户提交表单后跳转至自定义 url。可用于记录跳转参数便于运营数据参考，这款插件还可以将用户填写的信息传递到 url，以实现简单的跨页面传参呈现用户信息。

总结一下配合使用的插件

由于 Contact form 7 轻量迷你且免费，所以很多功能的实现需要配合其他辅助插件使用 如下:(不提供插件下载，这些基本后台都可以搜索得到)

• Contact form 7 插件：Contact form 7
• 配合同步到 MailChimp:Contact Form 7 Extension For Mailchimp
• 配合记录用户填写的表单:Contact Form CFDB7
• 配合提交后跳转 url 和链接传参:Redirection for Contact Form 7
• 配合弹窗插件:JetPopup (内附多套样式，便于参考或修改)
• 推荐好用的页面构建器: Elementor

创建完表单如何实现插入到页面呢？

非常简单，Contact form 7 新建表单后会生成一串短代码，将短代码插入到文章相应位置即可。如下图:

当然，配合上边推荐的 Elementor 元素插件（页面构建器），可以通过 Elementor 内在模块快捷插入 Contact form 7 表单。

如果你想实现弹窗让访客提交表单信息，实际上你只需要借助别的插件弹窗，弹窗内容插入 Contact form 7 表单的短代码即可实现。反正就是一句话，想以什么方式呈现，就把短代码放到相应位置即可。弹窗功能可以使用 Elementor 插件实现。

Contact form 7 进阶操作

Contact form 7 插件提供了非常多的内置函数字段以帮助我们拓展功能，我们可以利用这些来收集访客 ip 浏览器 ua  提交页面等。

列举几个常用的字段：

• 用户表单信息(默认情况字段):[your-email]
• 提交用户 ip:[_remote_ip]
• 提交时间:[_time] [_date]
• 提交用户浏览器信息:[_user_agent]

如何在表单内收集用户上传文件并通过 email 邮件附件发送给我们？

可以利用表单内的插入文件标签，实现前端用户文件上传。

要实现自动发送给我的 email，只需要将 [file 自定义字段名] 表单填写到 mall 项（就是用户提交表单后发送 email 配置）的 File attachments 内即可。如下图：

上边这一串是 前边所定义的字段，这里插件帮你总结出来，方便你插入标签。

另外提一下，如果你想利用 Contact form 7 插件在用户填写完表单后给他发送邮件，可以点击下边的 Mail(2) 这里的意思就是多开一项发送的邮件。但他是可独立设置的。如图:

本地附件字段格式:

1. [your-file][your-another-file]
2. uploads/2020/07/zmki.pdf

复制

插件的函数标签 官方还有很多，这里暂且只写出了这么多，有兴趣可以去官网文档了解一下: Special mail-tags

下边提供一些比较常见的表单结构（共 110 套），使用方法如下

• 10 套表单在线演示 demo: www.hunktest.com/contact-form-7
• 本文提供的表单代码为了方便快速创建表单结构，如需要外观比较完美展现  还需要自己一定动手能力。
• 在安装好的 contact form7 的 WordPress 中新建表单，然后把下面的表单代码复制进去。
• 下列的表单为了美观基本上都有自己的 css，需要你引入到使用的页面。比如放到主题的 style.css 内
• 部分表单 字段比默认的多，所以在你做好表单之后。将表单内多出的字段复制到 邮件发送项，避免用户填写完之后无法接收到。
• 另外，部分按钮由于 css 没有给他定义颜色，会根据你的主题默认颜色呈现。

表单常见元素 css 修改 类名称 参考 示例:

输入框高度

.wpcf7-form-control-wrap input{height:30px!important;}

复制

输入框外部下边距

.wpcf7-form-control-wrap textarea{height:100px!important;}

复制

信息框高度

.wpcf7 p{margin-bottom:10px!important;}

复制

可以快捷在插件类写入 css，不过有时候不会生效，插件原因不生效可以丢到主题内的样式表里边。
