Title: Dynamic Stylesheet and get_theme_mod() error Last modified: August 30, 2016 --- # Dynamic Stylesheet and get_theme_mod() error * [WebTrooper](https://wordpress.org/support/users/webtrooper/) * (@webtrooper) * [10 years, 8 months ago](https://wordpress.org/support/topic/dynamic-stylesheet-and-get_theme_mod-error/) * I’m having an issue while trying to use a dynamic stylesheet, mystyle.css.php, getting the error “Fatal error: Call to undefined function get_theme_mod()” * I registered and enqueued the the stylesheet in my functions.php file, as follows: * ``` wp_register_style('mystyle', get_template_directory_uri() . '/bc-parts/mystyle.css.php'); wp_enqueue_style('mystyle', get_template_directory_uri() . '/bc-parts/mystyle.css.php'); ``` * And this is the stylesheet: * ``` a:link, a:visited:link { color: ; ``` * I’m using WordPress Customizer with Kirky plugin. My objective is to use a dynamic stylesheet rather than having all the generated styles output to the head of the theme. * What am I missing? * Thanks 🙂 Viewing 4 replies - 1 through 4 (of 4 total) * Moderator [bcworkz](https://wordpress.org/support/users/bcworkz/) * (@bcworkz) * [10 years, 8 months ago](https://wordpress.org/support/topic/dynamic-stylesheet-and-get_theme_mod-error/#post-6599535) * You can’t directly request custom PHP pages in WP. You’ll see some work arounds where the requested page includes wp-load.php, but that is not a truly workable solution. This is all explained here: [http://glennmessersmith.com/pages/wpenviro.html](http://glennmessersmith.com/pages/wpenviro.html) * As it happens, he uses a dynamic CSS file as an example! * Thread Starter [WebTrooper](https://wordpress.org/support/users/webtrooper/) * (@webtrooper) * [10 years, 8 months ago](https://wordpress.org/support/topic/dynamic-stylesheet-and-get_theme_mod-error/#post-6599571) * Thank you, bcworkz. In my search for a solution I did find mentions of wp-load. php, and now it makes perfect sense. I realize this is not a perfect solution, as it loads way more code than what I need for a simple stylesheet, but now I can move forward with my project while I try to find a more efficient solution. Have a great day! * [catacaustic](https://wordpress.org/support/users/catacaustic/) * (@catacaustic) * [10 years, 8 months ago](https://wordpress.org/support/topic/dynamic-stylesheet-and-get_theme_mod-error/#post-6599578) * I’d suggest to do it the way that they do it in the codes pages. That’s to add in a block of CSS in the `` tags using the `wp_head` action. There’s no need for any outside files, no loading more resources than are required (because they’re alreayd loaed anyway), and you can easily control where the code is output by varying the `$priority` argument. * Thread Starter [WebTrooper](https://wordpress.org/support/users/webtrooper/) * (@webtrooper) * [10 years, 8 months ago](https://wordpress.org/support/topic/dynamic-stylesheet-and-get_theme_mod-error/#post-6599587) * Thanks for the tip, Catacaustic, but that’s exactly what I’m trying to not do. The stylesheet is really huge.
