FooKelvin Posted September 1, 2015 Share Posted September 1, 2015 (edited) Hello, I have stuck in here. Let me explain the background. Each Fiscal Year have Q1 until Q4. Each Quarter have different type form name. In a quarter may have more than 4 forms. So, each form is to track the points that the participant earn. One form allow more than one participant. One participant can participate in multiple form. So each participant have a total marks for each form. Please Have A Look The Attachment. Right now, I need to design a report to show Top 20 highest score participant. It can be cumulative from Q1 + Q2 + Q3 + Q4. Mean that, for example:- In This case. The data is less, so i highlighted Top 3 highest score. +---------------+ |Bill | 41 | |Aaron | 36 | |Gates | 27 | +---------------+ To produce this filter, the only way i can think off is to sum all the data in a database by name?? is that a good way? or is there any better way? Thank You Edited September 1, 2015 by FooKelvin Quote Link to comment https://forums.phpfreaks.com/topic/298011-php-matrix-with-cumulative/ Share on other sites More sharing options...
scootstah Posted September 1, 2015 Share Posted September 1, 2015 Well, you need to model this for a relational database and not for a spreadsheet. Here is a basic schema example: category ---------- id | name ---------- 1 | attendance 2 | contribution question ---------- id | question ---------- 1 | Attend more than 5 times? 2 | Attend more than 20 times? form ---------- id | name | quarter | year ---------- 1 | Form 1 | 1 | 2015 2 | Form 2 | 2 | 2015 3 | Form 3 | 3 | 2015 4 | Form 4 | 4 | 2015 user ---------- id | name ---------- 1 | James 2 | Gates result ---------- id | form_id | category_id | question_id | user_id | points ---------- 1 | 1 | 1 | 1 | 1 | 2 2 | 1 | 1 | 1 | 2 | 3Then you can use a simple query to get the number of points for each user:select sum(points) from result group by user_id;You could additionally group by category, question, or form.
