[wp-hackers] Like Posts - Store Data in DB, User_Meta or Post_Meta

[BenderisGreat]

Would this be the fastest way to check the database?

function alreadyLikedCheck() {
	global $wpdb, $post, $current_user;
      get_currentuserinfo();
	  
	  $user_id = $current_user->ID;
	  $post_id = $post->ID;
	
	$checkLikeTable = $wpdb->get_row( $wpdb->prepare('SELECT * FROM ' .
$wpdb->prefix . 'ams_post_likes' .' WHERE user_id = %d AND post_id = %d',
$user_id, $post_id ));
	if (isset($checkLikeTable)) {
		echo "You Like This Post";
	} else 
	{ echo "<button type='button' id='post_like' data-id='".get_the_ID()."' 
data-nonce='".wp_create_nonce('like_button')."'
data-user='".get_current_user_id()."' class='btn btn-success'>Like This
Post</button>"; }
	
	
}
