Hi peeps,

 

I am trying to work out hot to create a schedule to allocate games to teams within a league this is what I am trying to attempt

 

Season has 70 days

[league match] Every Mon

[league match] Every Tue

[reserved for cup match] Wed

[league match] Every Thu

[league match] Every Fri

[reserved for cup match] Sat

[no game] Sun

 

Any assistance would be appreciated, and I will be looking around to see if I can find similar code to give me a head start.

 

Regards

BB

I'm assuming 70 days would be 10 weeks..

 

and

 

if so create a table with 5 fields

 

id - int - auto increment

home_team - text

^^ something like "BunnySlippers"

away_team - text

^^ something like "TeddyBears"

week - int

^^ something like 1-10 for like.. week 1.. week 2..

day - int

^^ something like 1 - 7 for day1 day2 day3

 

then when you want to pull week 2 of the database

you'd just do

 

"SELECT * FROM `yourTable` WHERE `week` = '2'"

 

  • 4 weeks later...
