<#IsSunny> Webtag

captzero · **Posted:** Sun Jan 30, 2011 11:22 pm

Hi Steve,

Cumulus help file says -<#IsSunny> returns 1 if the sun is shining, otherwise 0. Its returning 0 for me all the time. I have changed the time format in all my sun/moon/daylight tags. Would this break the <#IsSunny> tag?

Thanks

First question: Have you got a solar sensor?

captzero · **Posted:** Mon Jan 31, 2011 9:14 am

No, no sensor.

Cumulus can't tell whether the sun is shining or not unless you have a solar sensor.

No Probs, That explains it. I thought it may have worked from the dawn / dusk or sunrise / sunset tags.

That wouldn't give Cumulus enough information, it could be cloudy? Although the Cloudbase webtag calculates cloudbase, it is just a calculation and can't be relied on.

No worries. I was thinking it was like - its day time or night time at the station location.

There is a webtag for that, <#isdaylight>. It returns 1 if it is daylight, 0 for nighttime.

Thanks Paul, I thought there was but I must have missed it.

You're welcome. You probably already know, but you can use that webtag to display a day or night icon, some simple code like:

Code:

<img src="daynight_<#isdaylight>.png" title="Lamp off=daylight, Lamp on=darkness here">

You need two icons, daynight_0.png and daynight_1.png or whatever.

Yeah, I was using the other tag to display some simple text. Worked a treat until the sun came up and the script didn't change. lol :oops:

I didn't know, that's quite neat

Can you use <#.......> in any html code for this substitution?

Yes, that's how many display a forecast icon, i.e. have a set of 26 weather icons named weather_1.png to 26. Then just substitute the number with <#forecastnumber> .

I use a few webtags and javascript to change a few images on my pages.

I've just included the <#isdaylight> tag to display a simple text (day or night at my location). I use it under the world image on my front page.

<script type="text/javascript">
var sun = "<#isdaylight>";
if (sun==1)document.write('Day Time')
else document.write('Night Time')
</script>

You and use it to display a different image (or text) as your webtag changes the data. There is lots of info in the forum on how to do it.

Use an on line editor to test. There are lots but I use http://www.onlinehtmleditor.net/

Have fun.

You can use a web tag anywhere; it's just a simple textual substitution, the processor doesn't know anything about HTML etc.
