Description
Used to output additional <head> HTML to pages where ACF fields appear.
This action is similar to the WordPress admin_head, except that it is only fired on pages where ACF fields appear – such as when editing posts, users, taxonomy terms, options pages and front-end forms.
Changelog
- Added in version 4.0.0
Example
This example demonstrates how to output additional inline style and script tags to customize fields.
functions.php
<?php
add_action('acf/input/admin_head', 'my_acf_admin_head');
function my_acf_admin_head() {
?>
<style type="text/css">
/* CSS here. */
</style>
<script type="text/javascript">
(function( $ ){
// Javascript here.
})(jQuery);
</script>
