php - Getting similar posts by title? -

i looking @ trying posts contain name , code have half working. pulls through standard posts not sure how show custom post types well.

here code in functions.php

add_filter( 'posts_where', 'wpse18703_posts_where', 10, 2 ); function wpse18703_posts_where( $where, &$wp_query ) {     global $wpdb;     if ( $wpse18703_title = $wp_query->get( 'wpse18703_title' ) ) {         $where .= ' , ' . $wpdb->posts . '.post_title \'' . esc_sql( $wpdb->esc_like( $wpse18703_title ) ) . '%\'';     }     return $where; } 

here code uses function find posts of name.

    <div class="main-content large-8 medium-8 small-12 columns">         <h2><?php the_title(); ?> news , features</h2>         <?php         $title = $wp_query->post->post_title;         $query = new wp_query(             array(             'wpse18703_title' => "$title",             'posts_per_page' => 10,              'post__not_in'  => array($post->id),                 'post_type' => array('post', 'it_review')             )         );          if ($query->have_posts()){             while ( $query->have_posts() ) { $query->the_post(); ?>                 <div class="small-12 large-12 gdb-news-container">                 <div class="small-12 large-4 columns gdb-news-image">                     <?php the_post_thumbnail(); ?>                 </div>                 <div class="small-12 large-8 columns">                     <h3><?php the_title(); ?></h3>                 <?php echo content(20); ?>                 </div>                     <div class="clearfix"></div>                 </div> 

my ideal scenario use title of game example fallout 4 , shows posts containing in title.

looking on code fresh pair of eyes noticed did not put correct post type in 'post_type' => array('').

after including correct post type has started pull through posts well.

thought answer in case else miss me.
