Wordpress Search for post

Question

I have a pertinent question that I have been trying to resolve for some time. On my website I have 2 custom search modes and on different pages, however when creating the 3rd I see the results on the page but I can’t use the search block. Someone who can shed a light...

if ( !is_admin() ) {
    // custom search 
    add_filter( 'posts_join', 'custom_search_join' );
    add_filter( 'posts_where', 'custom_search_where' );
    add_filter( 'posts_groupby', 'custom_search_groupby' );
}

// search with join
function custom_search_join($join) {
    if ( is_search() && isset($_GET['s'])) {
        global $wpdb;
       $join = " LEFT JOIN $wpdb->postmeta ON $wpdb->posts.ID = $wpdb->postmeta.post_id ";
    }
    return($join);
}

// search with groupby
function custom_search_groupby($groupby) {
    if ( is_search() && isset($_GET['s'])) {
        global $wpdb;
        $groupby = " $wpdb->posts.ID ";
    }
    return($groupby);
}

        // search with where
        function custom_search_where($where) {
            global $wpdb;
            $old_where = $where;
            if (is_search() && isset($_GET['s']) && !isset($_GET['segundo_search']))
        {
                // add additional custom fields here to include them in search results
                $customs = array('_mais1', 'mais2', '_mais3', 'mais4');
                $query = '';
                $var_q = stripslashes($_GET['s']);
                preg_match_all('/".*?("|$)|((?<=[\\s",+])|^)[^\\s",+]+/', $var_q, $matches);
                $search_terms = array_map(create_function('$a', 'return trim($a, "\\"\'\\n\\r ");'), $matches[0]);

                $n = '%';
                $searchand = '';
                foreach((array)$search_terms as $term) {
                    $term = addslashes_gpc($term);
                    $query .= "{$searchand}(";
                    $query .= "($wpdb->posts.post_title LIKE '{$n}{$term}{$n}')";
                    $query .= " OR ($wpdb->posts.post_content LIKE '{$n}{$term}{$n}')";
                    foreach($customs as $custom) {
                        $query .= " OR (";
                        $query .= "($wpdb->postmeta.meta_key = '$custom')";
                        $query .= " AND ($wpdb->postmeta.meta_value  LIKE '{$n}{$term}{$n}')";
                        $query .= ")";
                    }
                    $query .= ")";
                    $searchand = ' AND ';
                }
                $term = $wpdb->escape($var_q);
                $where .= " OR ($wpdb->posts.post_title LIKE '{$n}{$term}{$n}')";
                $where .= " OR ($wpdb->posts.post_content LIKE '{$n}{$term}{$n}')";

                if (!empty($query)) {
                    $where = " AND ({$query}) AND ($wpdb->posts.post_status = 'publish') AND ($wpdb->posts.post_type = 'primeiro_listing')";
                }
            } else if (is_search() && isset($_GET['s'])) {

            // added custom fields here to include them in search results
                $customs = array(

                    $searchand = ' AND ';
                }

Answer 1

You’d have to send your form action to a location where the search is processed by what I see in the code:

<form action="<?php echo esc_url( home_url() ); ?>/" method="get" id="searchform">

It is sending to the initial WP URL also the id of form should be amended.

You can check the other two forms what they have of similar and follow the same rule.

If you want to post the other two I can help you better.
