Alternate week display

motorbelly

I am trying to figure out a way to show alternate week info, either a change in text color or a change in graphic display.

I know of some calendar commands but nothing that does what I need.

Any thoughts out there?

😕

Where's the 'info' coming from? How is it being displayed? What's the format of the 'info' you're working with? 🙂

hey dale, ever remember those word problems in math that you can answer "Not enough information", Thats the choice I select here.. "Not enough information.", 🙂

Alright guys, you're right. 🙂

I'm still at this (just been doing without all this time) I'm trying to show what collection week it is, the city is divided in two, half collected one week, the other half the next.

I need a way to display "It's blue week" or "It's green week" (today is blue week) or have it display a graphic for one week and another for the other.

I've also thought about having the style.css be changed...

Simple is best. I'm not very bright and I'm getting older instead of wiser it seems. 😃

Kind of an interesting problem. Here's my kludge:

<?

$start=strtotime("last Sunday");
$now=time();
$color=getColor();  //decide where you're going to store this
// ... db?  textfile?

$next=$start+604800;
if ($now>=$next) {
   $color=ChangeColor($color);
   $store=StoreColor($color);
   }

function ChangeColor($color) {
   if ($color=="blue") { $color="green"; }
   elseif ($color=="green") { $color="blue"; }
   else {return false; }
   return $color;
}

function StoreColor($color) {

// Like I said, decide and code...

}

function getColor() {

//ditto

}

echo "This week is $color...";
?>

Hold the phone, though; that's not quite right...testing more code....

dalecosp

Doh! Yes!!!! [man]strtotime()[/man]!!

I love the manual!! And the forum search too!

I edited the script above ... should do what you want, once you get the storage done the way you want it...!!

🆒

How about

echo  "Its ".(date('W')%2)?"blue":"Green" . "week.";

Very good, except date('W') starts the week on Monday.

Nonetheless, the lazy man wins again....

I thought that was really wierd, but I didn't think it would matter for garbage collection 🙂

I am having a lot of trouble with this and I really apprecaite you input today.

I didn't understand the need for a database but I gather it is to help start the week on Sunday?

The second solution is more along the lines I was thinking but I never got it to work. I can never get all the '"'s right. 😕

thought I was groking this PHP stuff but I need to hit the beginners stuff again.

Thank you very much for the guides!

The "Its" and "week" wasn't displaying and I wanted to show more color so I've tried:

<?
echo  "It's ";
echo  " ".(date('W')%2)?"<font color=\"blue\">blue</font>":"<font color=\"green\">green</font>";
echo  " week.";
?>

But now how do I test it? Changing date on my Win box doesn't do it. Has Apache loaded the date?

HalfaBee

You can test it using


date( "W",strtotime( "+7 day" ) );

echo  "It's ";
echo  " ".(date('W',strtotime( "+7 day"))%2)==0?"<font color=\"blue\">blue</font>":"<font color=\"green\">green</font>";
echo  " week.";

It also needs the ==0 test.

The "need for a database" should be translated simply "the need for PHP to know what the last week was so it could determine whether or not to change colors."

In effect, then, the first solution would cause PHP to change a marker (either held in a database or a writable text file on the server, hence my comment "decide where you're gonna store this") upon the first loading of the page when the week had changed, and the IF clause would be checked, but not evaluated to true, for every other page load.

HalfaBee's solution is much more elegant; mine is a kludge --- just in case you wanted to know what those terms meant. His solution builds on the fact that PHP already knows which ordinal week of the year it is. It will check on each page load and respond correctly. The only potential advantage mine has is that, as I mentioned, I started it on Sunday.

As for your remaining issues, HalfaBee's got you covered 😉
