Hi i'm using this code to call for a different stylesheet for a single post type but the problem is, It won't call the stylesheet.

It's in header.php, i also tried placing it in single.php

if ( ! is_home() ) {

if ( is_single() == 'pretty-little-liars' )  {
    echo '<link rel="stylesheet" href="http://www.tv-cafe.com/wp-content/themes/tvcafe/posttypecss/style-pll.css" type="text/css" media="screen" />';

can anyone tell me what the problem is?

is_single() returns TRUE or FALSE, not a string. Additionally, you can test for a specific post with is_single() function by putting the post slug into the function call:

if ( is_single( 'your-post-slug' ) )
    # do something

If you want to test for the proper post type use:

if ( is_singular() and 'your-post-type' === get_post_type() )

or just:

if ( is_singular( 'your-post-type' ) )


And for your specific question, you should wrap that script into a callback, hooked into wp_enqueue_scripts. In functions.php:

function wpse78368_enqueue_custom_stylesheet() {
    if ( is_singular( 'pretty-little-liars' ) ) {
            get_template_directory_uri() . '/posttypecss/style-pll.css' 
add_action( 'wp_enqueue_scripts', 'wpse78368_enqueue_custom_stylesheet' );

Note: Use wp_enqueue_scripts because wp_enqueue_styles doesn't exist as a do_action().

Het @Toscho thanks, but doesn't add_action( 'wp_enqueue_scripts', 'wpse78368_enqueue_custom_stylesheet' ); go before function wpse78368_enqueue_custom_stylesheet() { – Mihad Aiko Jan 5 '13 at 23:52
@MihadAiko The order doesn’t matter. – toscho Jan 5 '13 at 23:55
Ok, this works perfectly thank you :) – Mihad Aiko Jan 5 '13 at 23:58
Thank you too chip – Mihad Aiko Jan 6 '13 at 0:35
i didn't place the enueing in the header i placed it in the functions.php if i use is_single( 'pretty-little-liars' ) it won't work i have tried that. Are you saying that if i call it in functions.php i don't need to call it in the header, because it doesn't work by just calling it in the functions or just in the header. – Mihad Aiko Jan 6 '13 at 23:34
