This Month's rain when none has fallen

[RayProudfoot]

Hi Steve,

Looking at the data for rain for This Month it doesn't look quite right when no rain has fallen.

Is there any way the tags could be made invisible until there is some rain data to display?

As long as you are exporting your file(s) as PHP, the followig will work:

Code: Select all

if ( $rfallmH > 0 ){
    
    // Put your display in here - if the monthly rainfall is zero, nothing will display
}

Change the tag to suit whatever section you want (daily, hourly, monthly, yearly falls etc.

You can also use the if()... statements to also provide a display if nothing has fallen eg

Code: Select all

if ( $rfallmH > 0 ){    
    // Put your display in here - if the monthly rainfall is zero, nothing will display
    echo $rfallmH . " recorded so far this month.";
}
else
{
    // Now display a message saying no rain has been recorded
    echo "Nil rain recorded so far this month";
}

Whoops just realised - the above code assumes you are creating a single webtags file and then doing the tanspositions in the PHP files when you display them instead of creating lots of individual files that Cumulus processes (if that makes sense).

If you are processing the files through Cumulus replace the $rfallmH PHP variable with the Cumulus tag - it will still work that way.

You could put some javascript in your HTML to display something else when you've had no rain.

As an example of how to do this using javascript, I've modified my todayT.htm template. The code for the time of today's max rain rate is currently:

Code: Select all

<td>at&nbsp;<#TrrateTM>"</td>

which displays as:

Sanday weather - Mozilla Firefox_2011-05-05_09-45-01.png

I added some javascript so that the time is only displayed if the max rain rate isn't zero:

Code: Select all

<td><script type="text/javascript">if (<#rrateTM> != "0.0") {document.write("at&nbsp;<#TrrateTM>")}</script></td>

and it now looks like this:

Sanday weather - Mozilla Firefox_2011-05-05_09-43-56.png

Note that I'm not a javascript expert and there may be better ways of writing the code!

Thanks Steve and serowe. I think I have enough information from your examples to change my HTML template files.

BUT!!! Sod's Law strikes again. It started raining this afternoon after 23 days without rain. Quite a rarity in this part of the world.

Which is the rarity? The fact is hasn't ben raining or that it is raining?

The former. Manchester has a reputation for damp weather so to go 23 days without any measurable precipitation is quite unusual.
