In the world of WordPress web development, the function of role search may sometimes interfere with how you want your search functionality to operate. If you’re looking to tweak your search form without the role search, you’re in the right place. In this article, we will guide you through a step-by-step process to remove role search in the get_search_form function, thereby customizing your website’s observational capabilities to better suit your unique needs.
function wpturbo_remove_role_search($form) {
$form = preg_replace('/<input type="hidden" name="post_type" value="rolesearch" />/', '', $form);
return $form;
}
add_filter( 'get_search_form', 'wpturbo_remove_role_search' );
The function wpturbo_remove_role_search receives the current search form markup as an argument ($form). The aim of this function is to manipulate this passed $form markup by removing the hidden input field <input type="hidden" name="post_type" value="rolesearch" /> using a regex pattern that matches this input.
The first thing the function does is calling the PHP function preg_replace. This function is widely used in PHP to replace parts of a string that match a specific pattern. In this case, the pattern is provided by the first argument which is '/<input type="hidden" name="post_type" value="rolesearch" />/'.
This pattern represents the exact HTML input tag that needs to be removed from the search form. If this pattern is found within the $form markup, preg_replace will replace it with an empty string (''), effectively removing this input field from the form.
Finally, after this search and replace operation, our modified $form is returned from the function. Any subsequent code or WordPress functionality that handles or outputs the search form will now use the changed version.
The wpturbo_remove_role_search function is then attached to the get_search_form WordPress filter hook using add_filter. This hook allows for modifying the search form HTML before it is output to the browser. The function will be called anytime the search form is to be displayed, and it will adjust the form’s HTML as per the above specifications.
