rating

问题 In my database users can add a vote from 1 to 5 stars to every groups. Then I have to display a leaderboard by those votes. What I was doing until now is to order them by votes average without a weight. This is not so nice because a group having 5.0 with 20 votes is before of a group having 4.9 avg and 10000 votes. This is my votes table: CREATE TABLE IF NOT EXISTS votes( user_id BIGINT, group_id BIGINT, vote SMALLINT, vote_date timestamp, PRIMARY KEY (user_id, group_id) This is how I sort

But I'm having problems trying to set the target for each element. What I want is to show the rating choice on hover over each star.

问题 The title says it all. I know the reviews are the native comments post type in Wordpress. I have included the code to add a comment. The problem is however I am unclear how to give the comment a rating and how to tie it to a particular product. When I use the comment_post_ID it does not seem to be assigning the comment (review) to the correct post. $time = current_time('mysql'); $data = array( 'comment_post_ID' => 1, 'comment_author' => 'admin', 'comment_author_email' => 'admin@admin.com',

问题 Would ENUM('1','2','3','4','5') be a sensible datatype for a product rating which must be between 1 and 5? Thanks! 回答1: Yes, that would be an appropriate data type since it enforces your domain. If you are going to add (or do any other mathematical operation) them together, however, a numeric data type might be better. 回答2: I suggest using TINYINT UNSIGNED NOT NULL or, for better ANSI/SQL compatibility, use: SMALLINT NOT NULL With an integer type, it is much easier to do calculations. ENUM is
