Advanced Custom Fields 是一款非常强大的自定义字段插件,允许你自己添加多种形式的自定义字段类型,比如 Image、Checkbox、File、Text、Select、True / False、Link、Textarea 等等,可以集成为一个或多个面板,支持导出字段为 xml 或php代码,还可以集成到主题或插件里。

该插件需要基础的PHP代码编辑能力,你需要修改主题面板文件来显示字段。

下面倡萌将做一个简单的测试演示。

1.在后台插件安装界面搜索 Advanced Custom Fields 即可现在安装,或者下载 Advanced Custom Fields

2.启用插件后,你就可以在左边菜单看到“字段”,进入后点击“新建”,就出现类似下面的界面。

点击“添加字段”,填写和选择相关信息,需要注意的是“字段名称”必须是英文、数字、短横线、下划线组成,不能有空格。比如倡萌添加了“test_text”和 “test_img”两个字段,分别为 文本 和 图像 类型。

显示“位置”为 文章类型 下的 “post”,也就是在文章编辑界面添加这个自定义字段组。

然后“选项”的“样式”设置为“标准MetaBox”,保存发布。

3.新建一篇文章,就可以在内容编辑器下方看到如下界面,就是倡萌刚才添加的字段(图中已经选择了图片)

 

4.重点就是如何调用这两个字段的值。看的懂英文的就自己查看下官方的教程 http://www.advancedcustomfields.com/resources/

下面只简单介绍下 the_field() 和 get_field() 函数。前者是直接输出字段值,后者是获取字段值以供其他函数调用。

比如,我们直接输出刚才倡萌添加的文本字段 test_text,可以使用下面两种方式打印:

<?php   //直接打印输出字段的值
the_field('test_text');   //使用 echo 打印输出
echo get_field('test_text');   ?>

综合下,倡萌要在文章底部输出刚才添加的 test_text 和 test_img 这两个字段,可以编辑主题的 single.php 文件,找到 the_content();  在下方添加:

<?php
if (get_field('test_text')) {
	echo '<p>输出文本字段:'.get_field('test_text').'</p>';
}   if (get_field('test_img')) {
	echo '<p>输出图像字段:<img src="'.get_field('test_img').'" /></p>';
}
?>

查看刚才的文章,就可以看到输出结果如下:
