search only php files

I’d love to know too. It’d be wonderful to add a multi-select dropdown to the search fields that would limit the search to certain file types.

That’s an interesting idea, I’ve added it to the enhancements board for the next release (I already had plans for the just released 2.5.0 version, so this didn’t make the cut for that one, unfortunately).

I’ve added it at https://github.com/Clorith/wordpress-string-locator/issues/272, and will look into that after the grace period after the 2.5.0 release (I don’t want to actively add new features right after a release in case there’s unexpected issues as a result of the update that need to be addressed).

I’m going to mark this topic as resolved, not because your request is fixed, but because there’s now a ticket to follow it up through, so that I know which topics might still need looking at here on the forums, thank you for the suggestions!
