I have an ACF field that adds custom CSS to the page associated with that field. I recently added the output of the field to the Editor page for a better editing experience that looked closer to the page output. It works, but I’m getting these errors:
Here’s the code on line 86 in functions.php:
$post_css = get_field(‘custom_css’, $post->ID); if ( !empty($post_css) ): echo ‘<style type=”text/css”>’ . $post_css . ‘</style>’; endif;
$post is not defined when function.php is loaded.
$post is not defined until your template file is loaded and usually inside “The Loop”
Is your above code part of some function that is called?
Hey John,
That makes sense, but somehow it does load the ACF field in the admin area correctly. This is the full equation:
// Load admin styling
function apache_admin_style() {
wp_enqueue_style('admin-css', get_template_directory_uri() . '/css/admin.css');
wp_enqueue_script( 'admin-js', get_template_directory_uri() . '/js/admin.js', array( 'jquery' ), null, true );
include get_template_directory() . '/inc/c-styling.php';
$post_css = get_field('custom_css', $post->ID); if ( $post_css ) { echo '<style type="text/css">' . $post_css . '</style>'; };
}
add_action('admin_enqueue_scripts', 'apache_admin_style');
I don’t think that $post will be defined at this point, so you may need to figure it out, see my comments
// Load admin styling
function apache_admin_style() {
wp_enqueue_style('admin-css', get_template_directory_uri() . '/css/admin.css');
wp_enqueue_script( 'admin-js', get_template_directory_uri() . '/js/admin.js', array( 'jquery' ), null, true );
include get_template_directory() . '/inc/c-styling.php';
global $post;
// this may still not be set, you may need to get the post ID from the URL ($_GET)
// or you may be able to use get_queried_object()
$post_css = get_field('custom_css', $post->ID); if ( $post_css ) { echo '<style type="text/css">' . $post_css . '</style>'; };
}
add_action('admin_enqueue_scripts', 'apache_admin_style');
