Wordpress - Query by post title
You can use either search parameter of wp_query :
Code
$args = array("post_type" => "mytype", "s" => $title);
$query = get_posts( $args );
Or you can get posts based on title throught wpdb class:
global $wpdb;
$myposts = $wpdb->get_results( $wpdb->prepare("SELECT * FROM $wpdb->posts WHERE post_title LIKE '%s'", '%'. $wpdb->esc_like( $title ) .'%') );
Than you'll get post object in this form:
foreach ( $myposts as $mypost )
{
$post = get_post( $mypost );
//run your output code here
}
