            public function hero_search($placeholder=false){
                if ( empty($placeholder) ){
                    $placeholder = __('What are you looking for?', 'nebula');
                $override = apply_filters('pre_nebula_hero_search', null, $placeholder);
                if ( isset($override) ){return $override;}
                $form = '<div id="nebula-hero-formcon">
                        <form id="nebula-hero-search" class="form-group search ignore-form" method="get" action="' . home_url('/') . '" role="search">
                            <div class="input-group">
                                <i class="fa-solid fa-magnifying-glass"></i>
                                <label class="visually-hidden" for="nebula-hero-search-input">Autocomplete Search</label>
                                <input id="nebula-hero-search-input" type="search" class="form-control open input search nofade ignore-form" name="s" placeholder="' . $placeholder . '" autocomplete="off" autocorrect="off" autocapitalize="off" spellcheck="false" tabindex="0" x-webkit-speech />
                return $form;


    To override this PHP function, use this hook in your child theme or plugin ("my_custom" can be changed):

    add_filter('pre_nebula_hero_search', 'my_custom_hero_search', 10, 2); //The last integer must be 1 more than the actual parameters
    function my_custom_hero_search($null, $placeholder){ //$null is required, but can be ignored
        //Write your own code here
        return true; //Return true to prevent the original function from running afterwords

    You can completely disable this PHP function with a single line actions:

     add_filter('pre_nebula_hero_search', '__return_false');
