I had this problem and I just want to let everyone know.
Wordpress will not replace your sidebar search widget with Sage’s searchform.php in templates directory. Correct me if I’m wrong, but I spent some time trying to debug this, which wasn’t happening in Roots.
If you want to use searchform.php all you need to do is create a file called searchform.php in Sage’s root directory and simply:
Hope this helps someone else.
I was a bit confused on this too. My custom
searchform.php wasn’t getting picked up when it was in
templates/. I moved it to the root directory and it’s now working.
I don’t see any reason to then pull in another file in
templates/ as @justdayan did? Also, I don’t understand @ben’s response above. Could you explain?
I’m reviving this old thread because it was the clearest search result on the topic and the docs are a little confusing -
searchform.php used to be in the templates folder. It now isn’t, but I can’t find any explanation of that modification in the changelog.
This may sound pedantic, but i created a pointer file in theme root called searchform.php and pointed it to templates/searchform.php to make everything clear. Stupid, i know, but you expect 1 thing 1 place, and something else happens… i’d rather be explicit.
