WEBTAGS temperature compared to yesterday

[ChaserPeek]

Hi, can I show a tag with value of temperature compared to yesterday ? Example: today at h:xx:xx we have 15 °C, yesterday we had at same time h:xx:xx 13 °C, so I would have webtags (or function) that print "-2" compared to yesterday

Thanks, regards.

Hi,
I am sure there is a way with a little code knowledge...
I've been using this for many years which was shared here on the forum by acer2 http://komokaweather.com/weather/obe.htm
This not exactly what you are asking but should give you an idea with the following code:

Code: Select all

<table class="hoverTable" style="table border=0;bordercolor=#678090;width:100%;border-collapse: collapse; border-spacing: 0;" >
	<tr>
		<TD style="background-color: #a2b1bd">Date - Time<br />EST</td>
		<TD style="background-color: #a2b1bd">Temperature<br />&deg;C</td>
		<TD style="background-color: #a2b1bd">Dew Point<br />&deg;C</td>
		<TD style="background-color: #a2b1bd">Humidity<br />%</td>
		<TD style="background-color: #a2b1bd">Wind Speed<br />km/h</td>
		<TD style="background-color: #a2b1bd">Wind Gust<br />km/h</td>
		<TD style="background-color: #a2b1bd">Wind<br />Direction</td>
		<TD style="background-color: #a2b1bd">Barometer<br />mb</td>
		<TD style="background-color: #a2b1bd">Rain Today<br />mm</td>
	</tr>
	<tr>
		<td><#RecentTS m=1 format="%d - hh:mm tt"></td>
		<td><#RecentOutsideTemp m=1></td>
		<td><#RecentDewPoint m=1></td>
		<td><#RecentHumidity m=1></td>
		<td><#RecentWindSpeed m=1></td>
		<td><#RecentWindGust m=1></td>
		<td><script type="text/javascript">var WB="<#RecentWindAvgDir m=1>"; document.write(wDL(WB));</script></td>
		<td><#RecentPressure m=1></td>
		<td><#RecentRainToday m=1></td>
	</tr>

Enjoy,
Paul

Thanks Paul.

well, webtags template is good for me and I use it yet.
My question is: I would print the difference of temperature between today and yesterday. I think webtag <#RecentOutsideTemp d=1> is good: it print recent temperature 24h ago.
But, <#RecentOutsideTemp d=1> print the value of 24h ago. I would print the value of difference, example +3 ... or -4

I hope I explain good for you.
Regards.

[PaulMy]

Sorry, I can't help with actual coding. It was a html script provided by acer2 and I can follow the basics but that is all. I presume to show the difference, i.e. today minus yesterday, would need some other coding such as PHP but that is beyond my knowledge.

Enjoy,
Paul

[ChaserPeek]

Yes Paul, I think so. Maybe some script are needed, and I would know how can I process this difference.
new php file ?
function in realtime.txt file ?

Maybe admin of forum can help me

thanks

If you have the variables in PHP, then you could do something like...

Code: Select all

<?php echo "diff = " . ($var2 - $var1); ?>

[dazza1223]

or somthing like this Today Yesterday the One Year Ago is SQL base

Excuse me Mcrossley, can I add this function in my custom template.txtT ?

[beteljuice]

It's very hard to give you any definitive replies because we don't know how page is going to be constructed !
You also give the throwaway words PHP and realtime.txt and we don't know your knowledge base.

If the page is being constructed by Cumulus as a Template page AND being renamed on regular upload to ?????.php

Then something like ...

Temp: <#temp><#tempunit> (&Delta;T24 <?php echo (<#temp> - <#RecentOutsideTemp d=1>); ?>)

... but, if you have a 'static' php webpage that is being updated by realtime.txt then you've got to find another way
You are going to have to get the value of <#RecentOutsideTemp d=1> upto the web, then by php include and / or javascript ajax do the calculation / display.

The following is not elegant coding, it is not to coding standards, but it is very simple and would work in your custom template.txtT, so try it:

Code: Select all

<script>document.write((<#RCtemp> - <#RCRecentOutsideTemp d=1>));</script>)

(No use of PHP above, it uses JavaScript).
EDIT: RC prefix added to ensure that numbers understood by JavaScript in any environment using decimal commas

Good morning and thanks for your reply.

For beteljuice :

yes, I have some basics of PHP and I try your function. I explain better what I would want.

I would have a client.txt with some vaules. I created a template with some webtags, like this:
<#tempTH rc=y>|<#tempTL rc=y>|<#temp rc=y>|<#TtempTH rc=y>|<#TtempTL rc=y>|<#tempYH rc=y>|<#tempYL rc=y>|<#TtempYH rc=y>|<#TtempYL rc=y>|<#avgtemp rc=y>|<#avgtempY rc=y>|<#apptemp rc=y>|<#heatindex rc=y>|s|<?php echo (<#temp rc=y> - <#RecentOutsideTemp d=1>); ?>|

Please check the function in bold. Then I created new extra-web file and Cumuls generates new txt file like this:

23.6|19.4|20.7|09:30|07:25|20.8|18.7|23:49|20:45|20.6|19.7|20.9|20.7|s|<?php echo 20.7 - 20.7;?>

Well, I think Cumulus not "parse" the php function and rewrite the "text" because it is not a webtag.

So, because of I would have a final TXT file, and not a "pure" php to call with http, Cumulus can parse the function ?

For sfws:

I will try your function. I hope Cumulus will parse it !

[beteljuice]

If by parse you mean execute - then No - Cumulus is unaware of php or javascript.

What you have created there is a | delimited list of data.

You already have <#temp rc=y> in field #2 so you just need to add <#RecentOutsideTemp d=1> to the end (field #14)

but what is reading this data - php or js ???

your math is simply array[2] - array[14]

However: I note in your test, the values appear to be the same ?

[ChaserPeek]

Well, values are the same (similar) because the Davis station is in testing mode in my house, and I'm searching alternative solution of other software.

If cumulus not execute PHP, I think I must search another solution to have the value required in my data sequence.

My big problem is that I need a TXT file because the web software read the sequence and print the values by specific format

Maybe I must do 2 step

1) create the value in PHP. I must execute PHP via hosting to create the value required.
2) I must insert this value in TXT file. Maybe I must execute a second PHP that elaborates the txt.

For you it's a good idea ?

[beteljuice]

but what is ..

the web software read the sequence and ...

Why can't that prog handle the extra var and calculation ????

[Mapantz]

If cumulus not execute PHP, I think I must search another solution to have the value required in my data sequence.

PHP is a server-side language.
