| 20:23.19 | fungus | What's this I hear about Slack? is there a Slack channel for this group? |
| 20:54.10 | unum | yes |
| 20:54.39 | mindjuju | slack is of the devil! |
| 20:54.41 | mindjuju | but yes |
| 20:54.55 | mindjuju | so here is a programming question, i know there hasn't been one in here in AGES |
| 20:55.15 | mindjuju | i need to programmatically determine what grade somebody should be in |
| 20:55.36 | mindjuju | and I don't really want to update the code every year |
| 20:56.08 | mindjuju | so i was thinking that I should be able to define 12th Grade as ( x = year-12) |
| 20:59.19 | fungus | Ahh, I found it. Slack isn't bad if don't have an IRC server, or don't want to use a public one, or operate your own. |
| 21:02.49 | unum | what year |
| 21:02.55 | unum | what's year? |
| 21:03.10 | unum | or rather I should ask what value are you storing in the database |
| 21:03.35 | unum | birthdate? |
| 21:04.05 | unum | and how are we defining which grade they "should" |
| 21:04.15 | unum | I guess it depends on the purpose for this |
| 21:04.27 | mindjuju | we are storing the child's age |
| 21:04.39 | mindjuju | and new children are being added to the database all the time |
| 21:05.00 | mindjuju | so, we want to programmatically determine what grade they should be in, at the moment they are entered into the database |
| 21:05.08 | unum | ah |
| 21:05.20 | mindjuju | so, let's say we just entered today, Frank born june 6, 2003 |
| 21:05.36 | mindjuju | i would want the code to determine, they should be in grade ??? |
| 21:05.55 | mindjuju | then next year, (without changing the code) enter Susie born Feb 7, 2001 |
| 21:06.21 | unum | $birthdate=date_create("June 6, 2003"); |
| 21:06.42 | fungus | If the cutoff date is the same date every year, it can be done with basic date math. |
| 21:07.25 | unum | $last_sept=date_create("last september first"); |
| 21:07.47 | unum | $diff=$birthdate->diff($last_sept); |
| 21:08.16 | unum | $grade=$diff->Y - 5 |
| 21:08.44 | fungus | but it's prone to error due to exceptions, is it not? |
| 21:08.58 | mindjuju | i think that's where we're getting tripped up |
| 21:09.03 | mindjuju | i'm uploading the date doc now |
| 21:09.19 | mindjuju | https://usercontent.irccloud-cdn.com/file/vCjvIOXl/ |
| 21:09.22 | unum | by exceptions you mean children who skip grades? |
| 21:09.52 | unum | for certain purposes(soccer registration) you don't really worry about that |
| 21:10.00 | unum | you just want to show the expected grade |
| 21:10.26 | unum | what you really need to know is age on september 1st |
| 21:10.26 | mindjuju | let's make this an "all things being equal" in the normal case no grade jumping, they should be --- |
| 21:10.51 | mindjuju | see unum, i don't think it is as simple as just subtract 5 |
| 21:11.26 | unum | you calculate their age on the most recent september first and then subtract 5 |
| 21:11.30 | unum | I think that works |
| 21:13.05 | unum | actually you want to use august 31st |
| 21:13.09 | unum | not september 1st |

| 21:26.25 | unum | http://unum5.org/grade.php |
| 21:26.29 | unum | it's august 31st |
| 21:26.41 | unum | hmmm I thought I switched that site to https |
| 21:26.56 | unum | nope I did not |
| 21:30.29 | mindjuju | unum, that looks right |
| 21:31.07 | mindjuju | i'm using the case of a child born sept 2nd, 2003 (which is a day after the cutoff) |
| 21:31.14 | mindjuju | and it's correctly pushing them to 7th |
| 21:31.46 | mindjuju | can you dump out the code on this, i'm not sure why i made it so complex |
| 21:33.11 | unum | I'm cheating on one line |
| 21:33.19 | unum | let me figure out the right way to do that |
| 21:33.30 | mindjuju | k |
| 21:37.40 | unum | http://unum5.org/grade.txt |
| 21:37.54 | unum | there's probably a better way to come with "last august 31st" |
| 21:40.07 | unum | I wonder if strtotime could handle "last august 31st" |
| 21:40.46 | unum | that was the line I was cheating on, I had just typed in "2016-08-31" |
| 21:43.50 | mindjuju | ah gotcha |
| 21:45.02 | unum | I've implemented and maintain a payroll system |
| 21:45.09 | unum | so I've gotten pretty good with dates :) |
| 21:45.15 | ninnypants | if it doesn't handle "last august 31" you could also do strtotime( date( 'Y' ) . '-08-31 -1 year' ) |
| 21:45.31 | unum | a payroll system across timezones |
| 21:45.41 | unum | ninnypants: would yours work correctly in october? |
| 21:46.21 | unum | in october of 2016 I want last august to be 2016-08-31 |
| 21:46.37 | unum | speaking of the payroll system I was supposed to a git push |
| 21:46.41 | ninnypants | ah probably not |
| 21:47.36 | unum | on a friday.... |
| 21:47.41 | ninnypants | you'd have to add checks for what month of the year it was |
| 21:47.44 | unum | afternoon |
| 21:47.50 | unum | you know what I'll wait until monday morning |
