Custom post type template

In your file, find:

<?php get_template_part( 'content', 'single' ); ?>

Now if your file is named content-posttype.php, replace it with:

<?php get_template_part( 'content', 'posttype' ); ?>

Awesome, thank you so much :)

You're welcome :)

Hello Tom!
This information is very useful, thanks!

I'm also working with custom post types and I want to edit not only the page template but also the archive page. So in my child theme I've created single-myCPT.php where I wrote
<?php get_template_part( 'content', 'single-myCPT' ); ?>

I've also created archive-myCPT.php but I don't know how to reference my custom content replacing get_post_format().
<?php get_template_part( 'content', get_post_format() ); ?>

Hope I explained well...

Thanks in advance!

This line: get_template_part( 'content', 'single-myCPT' )

Will look for a file like this: content-single-myCPT.php

If you're already using a custom single-myCPT.php file, you might as well copy the code inside content-single.php, and replace this with it:

get_template_part( 'content', 'single' )

get_template_part() is cool as it allows you to only change the loop - not the entire single.php file. In your case, it's probably easier to keep everything in one file.

Dear Tom,

If i want to create a custom page, which page of your theme will be most usefull to get a basis ?

content.php, page.php ??

It depends on which areas you're editing. page.php is likely the one you want to edit.
