Timed Images Code

Instead of
$hour = date('H'); // hour of the day, 24 hour clock

Try using this:

$now = getdate();
$hour = $now['hours'];

While it shouldn’t make any difference, I can see where it might. PHP is a typed language, it just hides the types well.

As for how you display weekends, well, that’s simpler.

$weekday = $now['wday']; // 0 = Sun, 6 = Sat
if ($weekday == 0 or $weekday == 6) {
  $timepic = 'weekend';
} elseif ($hour > 1 or $hour < 6) {
	$timepic = '0100pic';
... etc ...

As for why it doesn’t change… Are you using WP-Cache or WP-Super-Cache? Those will cache the whole page, including the results of running this code. If you’re using either of those, you may want to set the expire time to 20-30 minutes or so.

Thanks Otto,

I made the recommended change, and that didn’t do anything. And since I’m not using WP-Cache or WP-Super-Cache, I was at a loss.

However, I made this change:
($hour > 1 or $hour < 6)

to

($hour > 1 and $hour < 6)

That worked. ??

If I knew anything about making plugins, I’d see if I could adapt this script. But I still have a LOT of work to do on this site, so I probably won’t be learning how to write plugins anytime soon. If anybody’s interested in tackling this one, go for it. ??

Damn. I can’t believe I missed that logic error. Probably because you used the word or instead of the more common || symbol. If it had been ||‘s I would have spotted it instantly. ??

Like I said, I’m no expert coder. I’m just guessing for the most part. ??

However, it’s 3pm and the banner just defaulted to picturenobody.jpg. Weird.

No, now that logic error I do see.

...
} elseif ($hour > 12 or $hour < 15) {
	$timepic = '1200pic
} elseif ($hour > 15 or $hour < 18) {
	$timepic = '1500pic';

What happens when the hour is 3 pm exactly? Ahh, that one is not covered.

You need to make all of them like this:

} elseif ($hour >= 12 && $hour < 15) {
	$timepic = '1200pic
} elseif ($hour >= 15 && $hour < 18) {
	$timepic = '1500pic';

The >= is a greater-than-or-equal-to.

Thanks! That did the trick.

Now I’ll try out the weekend code and see what happens. But I’ll have to wait until the weekend, I guess. ??

How does this look? One show is on from 1am-4am, Tuesday through Saturday.

$now = getdate();
$hour = $now['hours'];
$weekday = $now['wday']; // 0 = Sun, 6 = Sat
if ($hour >= 1 && $hour < 4 && weekday >=2) {
	$timepic = '0100pic';
} elseif ($hour >= 6 && $hour < 9) {
	$timepic = '0600pic';
} elseif ($hour >= 9 && $hour < 12) {
	$timepic = '0900pic';
} elseif ($hour >= 12 && $hour < 15) {
	$timepic = '1200pic';
} elseif ($hour >= 15 && $hour < 17) {
	$timepic = '1500pic';
} elseif ($hour >= 17 && $hour < 18) {
	$timepic = '1700pic';
} elseif ($hour >= 18 && $hour < 20) {
	$timepic = '1800pic';
} elseif ($hour >= 20 && $hour < 23) {
	$timepic = '2000pic';
} elseif ($hour >= 23 || $hour < 16) {
	$timepic = '2300pic';
} else {
	$timepic = 'nobody';
}
echo $timepic;
?>.jpg" alt="On The Air Now" />

Sorry, posted the wrong code. And it’s not working. ??

$now = getdate();
$hour = $now['hours'];
$weekday = $now['wday']; // 0 = Sun, 6 = Sat
if ($hour >= 1 && $hour < 4 && $weekday >= 2) {
	$timepic = '0100pic';
} elseif ($hour >= 6 && $hour < 9 && $weekday >= 1 && $weekday <= 5) {
	$timepic = '0600pic';
} elseif ($hour >= 9 && $hour < 12 && $weekday >= 1 && $weekday <= 5) {
	$timepic = '0900pic';
} elseif ($hour >= 12 && $hour < 15 && $weekday >= 1 && $weekday <= 5) {
	$timepic = '1200pic';
} elseif ($hour >= 15 && $hour < 17 && $weekday >= 1 && $weekday <= 5) {
	$timepic = '1500pic';
} elseif ($hour >= 17 && $hour < 18 && $weekday >= 1 && $weekday <= 5) {
	$timepic = '1700pic';
} elseif ($hour >= 18 && $hour < 20 && $weekday >= 1 && $weekday <= 5) {
	$timepic = '1800pic';
} elseif ($hour >= 20 && $hour < 23 && $weekday >= 1 && $weekday <= 5) {
	$timepic = '2000pic';
} elseif ($hour >= 23 || $hour < 16 && $weekday >= 1 && $weekday <= 5) {
	$timepic = '2300pic';
} else {
	$timepic = 'nobody';
}
echo $timepic;
?>.jpg" alt="On The Air Now" />

I want every image to appear Monday through Friday only, except 0100pic which will appear Tuesday through Saturday. All other times the default “nobody” image will appear.

The time of day is working correctly, but the day of the week isn’t working. It’s Saturday, and all the regular images are showing.

citizenkeith – were you able to get the code to work? I have almost the same need for the code for a similar application.

If it is working, can you post the code and a link to your site?

Thanks!
