I have a page with a custom template which has the search bar on it. I want to make it so that the search bar on this particular page only searches for posts in a specific category.
For example.
If the user clicks on a custom template page called 'scouts', there will be a search bar (that calls the normal search.php file). Due to the user being on this particular page, the search bar now only searches for posts in the category of 'scouts' and 'senior scouts'.
There will be multiple pages like this one, where the user can only search for posts in other specific categories.
How can I do this.
