I'd like to know it's possible to do something like this


I needn the post(45) only to have a custom template.

I know we can achieve this with page, like this


or by a templating file template-test.php

But I can't find if it's possible to do this with simple post (following the wordpress hierarchie, i think it's not possible)


  • what are you trying to achieve that requires that specific post to have a different template? – Tom J Nowell Feb 9 at 11:59

You have to follow this file name structure:


If you have a post names "Hello World" and the slug of post is hello-world then the template name will be single-post-hello-world.php


There is no default way to use id in template name. But you might try this snipped:

add_filter( 'single_template', 'load_post_template_by_id' );
function load_post_template_by_id( $single_template ) {
    global $post;
    if ( 'post' === $post->post_type) {
        $tmp_template = dirname( __FILE__ ) . '/single-post-'.$post->ID.'.php';

        if ( file_exists( $tmp_template ) ) {
            $single_template = $tmp_template;
    return $single_template;

Here I'm overriding the post template in a tricky way. Now if you have a post with id 42 and you have a template file named single-post-42.php then it should load automatically.

I didn't test the code. So use it with your own risk.

  • Is is possible now to do with the slug instead of the ID ? If the slug change, then the template will not work – lucrece Feb 9 at 14:14

  • Thanks a lot ! Wish wordpress will add this feature in some update (even if it's very situational) – lucrece Feb 10 at 15:33
