如何使用Contact Form 7添加Font Awesome图标以在Wordpress中提交按钮？

Question

我正在尝试使用Contact Form 7添加字体真棒箭头图标以在Wordpress中提交按钮。我有这样的：[提交课程：按钮“发送消息”]在css中：

.wpcf7-submit:before {
    content: '\f30b';
    font-family: 'Font Awesome 5 Free' !important;
}

它不起作用，任何想法？

Answer 1

我知道我参加派对有点晚了，但我刚刚找到了一个更容易的选择（或者至少我是这么认为的！），这有助于我在提交按钮上获得一个图标。

不需要伪元素，您只需将元素直接插入联系表单：

<!--add the following instead of [submit] in Contact Form 7-->
<button type="submit" class="wpcf7-submit">Send Message<i class="fas fa-arrow-circle-right"></i></button>
<img class="ajax-loader" src="/wp-content/plugins/contact-form-7/images/ajax-loader.gif" alt="Sending ..." style="visibility: hidden; opacity: 1;">

然后，您还可以将样式添加到按钮，如下所示：

/*Then you can add whatever style you want to your button*/

button.wpcf7-submit {
  background: #31D1D3;
  padding: 10px 15px;
  border: 0;
}

button.wpcf7-submit i {
  margin-left: 5px
}

button.wpcf7-submit:hover {
  color: white;
}

button.wpcf7-submit:hover i {
  color: white;
}

<link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.8.1/css/all.css">
<!--just for this example, presume you already have font awesome installed if you're looking to output a button-->


<!--add the following instead of [submit] in Contact Form 7-->

<button type="submit" class="btn primary wpcf7-submit">Send Message<i class="fas fa-arrow-circle-right"></i></button>
<img class="ajax-loader" src="/wp-content/plugins/contact-form-7/images/ajax-loader.gif" alt="Sending ..." style="visibility: hidden; opacity: 1;">

更新：

您甚至可以使用Font Awesome Ajax Loader而不是CF7加载器！

/*Then you can add whatever style you want to your button*/

button.wpcf7-submit {
  background: #31D1D3;
  padding: 10px 15px;
  border: 0;
}

button.wpcf7-submit i {
  margin-left: 5px
}

button.wpcf7-submit:hover {
  color: white;
}

button.wpcf7-submit:hover i {
  color: white;
}

<link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.8.1/css/all.css">
<!--just for this example, presume you already have font awesome installed if you're looking to output a button-->


<!--add the following instead of [submit] in Contact Form 7-->

<button type="submit" class="btn primary wpcf7-submit">Send Message<i class="fas fa-arrow-circle-right"></i></button>
<i class="fab fa-github ajax-loader" style="visibility: hidden; opacity: 1;"></i>

Answer 2

更新：

默认情况下，联系表单7使用<input type="submit">元素作为提交按钮。 input元素不能使用:: before / :: after伪元素，因为input elements don't have child nodes。

您需要将提交按钮更改为实际按钮（如here所示），以便您可以向其添加FontAwesome图标。

您还需要指定font-weight属性，否则浏览器将不会加载该字体。

.wpcf7-submit::before {
    content: "\f30b";
    font-family: "Font Awesome 5 Free";
    font-weight: 900;
 }

<link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.6.3/css/all.css" integrity="sha384-UHRtZLI+pbxtHCWp1t77Bi1L4ZtiqrqD80Kn4Z8NTSRyMA2Fd33n5dQ8lWUE00s/" crossorigin="anonymous">

<form action="" method="post">
  <button type="submit" class="wpcf7-submit">
    Send
  </button>
</form>
