Hello,

I do experience a problem when I want to create files in my delta_child folder for the following files:
- search.php
- search_gallery.php
- loop-single.php

I can't create a file for these and as a result i need to edit them in the original Delta folder. So when updating I always need to adjust these files again. Is there a solution to overcome this problem?

I can for others such as main.php, item.php, item-post.php, etc

@Hugo
Depends how they are included.
It should be in this way:
    include osc_current_web_theme_path_value($filename);

function osc_current_web_theme_path_value should check if file exists in child theme or parent one should be used.

Thank you,

Is this something to check within the file it self? or in another file (if yes: in the Delta or Delta_child)?

Use it like that in both.
Basically this function was created, i.e. if you use:
search_list.php

inside search.php

But you want to update only search_list.php in child theme, and do not want to touch search.php.

So in search.php main theme should use this function to include search_list.php and then in child, you only need to update search_list.php
