Add a custom class name to Wordpress body tag?
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?
For example, my body tag code is...
<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)
<body class="home blog logged-in">
Depending on 开发者_运维知识库the child theme I'm using at the time, I want it to be...
<body class="home blog logged-in mychildthemename">
You can use the body_class filter, like so:
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_class function.
You can also use it directly inside the WP body_class function which will append the string inside body class.
eg.
$class="custom-class";
<body <?php body_class($class); ?>>
http://codex.wordpress.org/Function_Reference/body_class
To add more classes to the filter, just add another line that adds another value in to the array:
add_filter( 'body_class','my_body_classes' );
function my_body_classes( $classes ) {
$classes[] = 'class-name';
$classes[] = 'class-name-two';
return $classes;
}
In case you're trying to add classes to the body tag while in the Admin area, remember to use the admin_body_class hook instead. Note that it's a filter which works slightly different since it passes a string of classes rather than an array, so your code would look like this:
add_filter('admin_body_class', 'my_admin_body_class');
function my_admin_body_class($classes) {
return $classes . ' my_class';
}
Try this..
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.
Simply edit your theme's header.php and change the class there (manually or according to some preset logic rules).
