WordPressの検索機能を無効化する方法（簡単・シンプル）

   Line 11 of method 2 was not hiding the search form for my installation, but makes the default form appear, which is loaded / generated by general-template.php’s function get_search_form (at least WordPress 5.4.2).

   The function applies the filter get_search_form. In case the filter returns null (null === $result, line 299), the previously loaded or generated default form will be shown or returned.

   To hide the form, I had to change line 11 needs to return an empty string:

   add_filter(‘get_search_form’, function ($a) { return ”; });

     That can vary from theme to theme where the file is after you to into your wp-content/themes/theme name file. Some themes have a header.php while others have the code in another location. If you reach out to your theme’s support they should be able to assist.

   Thank you for posting this! I was filling my site with all kinds of crazy codes I was finding on the internet in hope of getting rid of that doggone search box! Now everything is good!

   Thanks for this. Very useful.

   A few comments:

   1. Method 2 (manual) works for me (i.e., removing search box) on a child theme of twentyeleven, but only for a search *widget* added to a widget area. It leaves the search box that is hard-coded (using get_search_form()) into header.php. I know I can override the parent theme’s header.php by cloning/editing it, but I’l like to know how to disable that search form programatically.

   2. I cannot get Method 2 to work on a Genesis theme. I wonder if you or anyone has some insights here.

   3. A little thing: the method 2 script needs a closing brace on line 14.

   Ok it removed the search box but left the search title that we must now figure out how to remove.
   DO you have an plugin for that?
   Seems to me you would have an option like this already installed in the site builder.

   Sometimes you can disable the search feature for example, on an one page site that does not really need a search feature.

   Thanks for the article. What I need to know is: can I disable only some terms of the search and keep the search function working? I want to exclude things like /?s=d, download, thank, success, congratultions… terms that hackers use to find specific pages inside our sites.

   Can someone help me with this? TIA

   Thank you very much.
   I have just been hacked in the database of one of my websites and I have removed all the possible gates to these terrible annoying people, who have nothing to do in life but distroying other people work.
   So I removed the search forms but i did not know how to remove the query string.

    Another reason for disabling the search box that comes with WordPress is to replace with a different search box, such as Google Custom Search.

    Google Custom Search allows you to monetize your search pages provides you have an Adsense account.

      Yup. There’s also __return_true __return_false __return_zero and __return_empty_array

    Heh! Thanks for the tips I was looking to do this at one moment and had no clue on how I can do it!

    I’m having a hard time understanding the usefulness of this code. If search is unnecessary wouldn’t it make more sense to not include the search form? If you leave a search form on a page and then don’t let someone use that search form isn’t that very poor usability?

    Am I missing something?

      You can remove the search form in the design, but the functionality stays. Anyone who knows it is WordPress can simply add a /?s=keyword and search the site. But by removing the form and adding this code will take care of that problem. There will be time when you have a client that only wants pages or posts to be shown if the URL is available. This function will come handy in that sense.

      Yes it makes more sense to leave out search and other widgets and allow the customer to add them if they want them and not put them by default.

    Hmmmm…. can’t imaging Search not being important for a CMS. Isn’t the fact that WordPress has such a fine Search feature a huge advantage when using it as a CMS? I can imaging Search only being not important on a small portfolio site say limited to 5 pages or so.

      There are times when you are using WordPress to create a standalone site for a client where you only want people to know about the pages if they have the URL.
