This can be useful for organisation but also for building functionality in a component or modular way or in a plugin.
<?php
add_filter( 'template_include', 'pattern_archive_template' );
function pattern_archive_template( $template ){
if( is_post_type_archive( 'pattern' ) ){
if( $_template = locate_template( 'template-parts/archive/archive-pattern.php' ) ){
$template = $_template;
}
}
if( is_post_type_archive( 'pattern' ) ){
if( $_template = locate_template( 'template-parts/archive/archive-pattern.php' ) ){
$template = $_template;
}
}
return $template;
}For example this means we can store the template files with the register custom post type script. In that example we would use:
<?php
$_template = locate_template( 'component/custom-post-type/pattern/archive-pattern.php' ) ){
// Or
$_template = locate_template( 'component/custom-post-type/pattern/single-pattern.php' ) ){
