First-Friday.php

[PHLAK]

A little php I smashed together from misc. code, modified, and threw in some of my own tricks, that will generate the first Friday of next month for you.

UPDATE: Latest revision available on Github: http://github.com/PHLAK/first-friday

Clever little add-in for the front page of the site to keep the information up-to-date automatically.

[PHLAK]

I'm an automation addict! I hate having to update things, even on a monthly basis.

[PHLAK]

UH-OH! The code is flawed... if you take a look, it's showing February 1st as the next meeting even though the next meeting is this Friday (January 4th). If anyone can, please take a look at the code and let me know if you see the problem. I'm pretty sure all we need to do is check to see if the first Friday of this month has already occurred, and if not, set that here:

Code: Select all

//Next Month//
    if($t[mon]=="12"){
    $nm='1-'.($t[year]+1);
    }
    else {
    $nm=($t[mon]+1).'-'.$t[year];
    }

I'm skiing until Thursday night, but will hopefully have time to check up on it while I'm not skiing. Thanks guys!

NOTE: I have removed some unneeded code in the original post to simplify.

[PHLAK]

I think I found a solution. This way it checks if the day of the month is <=7, and the weekday is before Friday. In the event it is, it will find the first friday of the current month, rather than next month.

Code: Select all

   //Calculate Next Month//
   if($t[mon]=='12'){
     $nm='1-'.($t[year]+1);
   }
   if($t[mday]<='7' && $t[wday]<='5') {
      $nm=($t[mon]).'-'.$t[year];
   }
   else {
      $nm=($t[mon]+1).'-'.$t[year];
   }


[PHLAK]

Code revised, it was calculating last Friday's date.

Added the following code:

Code: Select all

   if ($t[mon] == date('m',$date) && $t[mday] > date('j',$date) && $t[mon] == '12') {
      $nm = '1-'.($t[year]+1);
      $ff = get_day("first", "friday", $nm);
   }
   if ($t[mon] == date('m',$date) && $t[mday] > date('j',$date) && $t[mon] != '12') {
      $nm = ($t[mon]+1).'-'.$t[year];
      $ff = get_day("first", "friday", $nm);
   }
   else {
      $ff = $date;
   }


[PHLAK]

Just finished a total overhaul of the code. I learned some new tricks (specifically the mktime function) and was able to significantly reduce the code and simplify it. Check it out:

Code: Select all

<?php // first-friday.php v0.1.3 by, Chris Kankiewicz <http://www.web-geek.net>

  // Calculate next Friday
  for ($x = date('d'); $x <= (date('d') + 6); $x++) {
    $timeStamp = mktime(0,0,0,date('m'),$x,date('Y'));
    if (date('w',$timeStamp) == 5) {
      $nextFriday = mktime(0,0,0,date('m'),$x,date('Y'));
    }
  }
  // Check if next Friday is the first friday of the month.
  if (date('d', $nextFriday) <= 7) {
    $firstFriday = $nextFriday;
  } else {
  // Calculate first Friday of next month
    for ($x = 1; $x <= 7; $x++) {
      $timeStamp = mktime(0,0,0,date('m')+1,$x,date('Y'));
      if (date('w',$timeStamp) == 5) {
        $firstFriday = mktime(0,0,0,date('m')+1,$x,date('Y'));
      }
    }
  }

  // Echo next first Friday
  echo date("F j, Y", $firstFriday);

?>

[jargon]

There was a glitch due to converting from local time to UTC instead of from UTC to "local" UTC. (Same millisecond of day for same day that UTC offset would have.)

Here is the latest version of the script which includes clock render with the 5 weekly The KEAL Show "Supervillain Sunday" airtimes per month, the phx2600 meet-up, and the twice a month HeatSync Labs meet-up already pre-programmed.

The script requires the following to be in the page HTML that uses it:

Code: Select all

<p id="ticker">The "TKS" Monthly Ticker JavaScript has failed to load.</p><script language="JavaScript" src="./js/tks-monthly-ticker.js"></script>

1. The "p" and "/p" tag can be any two matching tags that encloses an empty or error-message-containing plain HTML body.
2. The script must be loaded after the tag with id as "ticker" closes.
3. The script replaces all contents between the opening and closing of that tag on-the-fly every 990 milliseconds with clock render updates.
4. I have yet to include an event trigger in the script that pauses rendering refreshes during mouse-over and mouse-highlight events, which would be one of the only ways to be able to allow copying to clipboard otherwise.

Enjoy; I hope you find this script useful.
