Add a custom class name to Wordpress body tag?
提问by Scott B
I'd like to place a directive in my theme's functions.php file which appends a classname to the wordpress body tag. Is there a built-in API method for this?
我想在我的主题的functions.php 文件中放置一个指令，它将类名附加到wordpress body 标签中。是否有内置的 API 方法？
For example, my body tag code is...
例如，我的身体标签代码是...
<body <?php if(function_exists("body_class") && !is_404()){body_class();} else echo 'class="page default"'?>>
And it results in the following being written to the body tag (depending on the context in which the page is presented (page, post, logged-in, etc)
它导致以下内容被写入正文标签（取决于页面呈现的上下文（页面、帖子、登录等）
<body class="home blog logged-in">
Depending on the child theme I'm using at the time, I want it to be...
根据我当时使用的儿童主题，我希望它是...
<body class="home blog logged-in mychildthemename">

You can use the body_classfilter, like so:
您可以使用body_class过滤器，如下所示：
function my_plugin_body_class($classes) {
$classes[] = 'foo';
return $classes;
}
add_filter('body_class', 'my_plugin_body_class');
Although, obviously, your theme needs to call the corresponding body_classfunction.
虽然，很明显，你的主题需要调用相应的body_class函数。

You can also use it directly inside the WP body_class function which will append the string inside body class.
您也可以直接在 WP body_class 函数中使用它，该函数将在 body 类中附加字符串。
eg.
例如。
$class="custom-class";
<body <?php body_class($class); ?>>

In case you're trying to add classes to the body tag while in the Admin area, remember to use the admin_body_classhook instead. Note that it's a filter which works slightly different since it passes a string of classes rather than an array, so your code would look like this:
如果您在管理区域中尝试向 body 标记添加类，请记住改用 admin_body_class钩子。请注意，它是一个过滤器，它的工作方式略有不同，因为它传递的是类字符串而不是数组，因此您的代码如下所示：
add_filter('admin_body_class', 'my_admin_body_class');
function my_admin_body_class($classes) {
return $classes . ' my_class';
}

Try this..
尝试这个..
add_filter( 'body_class', 'custom_class' );
function custom_class( $classes ) {
if ( !is_front_page() ) {
$classes[] = 'example';
}
return $classes;
}

If you just want to add class based on your page template note that WP now automatically adds per-template class to body tag.
如果您只想根据页面模板添加类，请注意 WP 现在会自动将每个模板类添加到 body 标签。

To add more classes to the filter, just add another line that adds another value in to the array:
要向过滤器添加更多类，只需添加另一行将另一个值添加到数组中：
add_filter( 'body_class','my_body_classes' ); function my_body_classes( $classes ) {
add_filter('body_class','my_body_classes'); 函数 my_body_classes( $classes ) {
$classes[] = 'class-name';
$classes[] = 'class-name-two';
return $classes;
}
}

Simply edit your theme's header.php and change the class there (manually or according to some preset logic rules).
只需编辑您的主题的 header.php 并更改那里的类（手动或根据一些预设的逻辑规则）。
