Testing Code!

[William Grimsley]

Hi there,

I've been putting in some new code into my ajax-dashboard.php file and wondered if it would work?

What I'm trying to do is not display the wind direction in both Javascript and AJAX when the wind speed is less than 0.0 mph.

Please can someone tell me if this code will work?

Code: Select all

<?php if (strip_units($avgspd) + strip_units($gstspd) > "0.0") echo "$dirlabel"; ?>

Thanks,

William

In what circumstances would you have a negative wind speed?

Edit: OK, looks like I misread the code. It looks OK.

Oh, yes! I never thought of that!

The code works fine, by the way!

Also, I had another peice of code:

Code: Select all

<?php $wr = $imagesDir . $wrName . $dirlabel . $wrType; // normal wind rose
				        $wrtext = langtransstr('Wind from') ." " . langtransstr($dirlabel);
			                        if ( (strip_units($avgspd) + strip_units($gstspd) < 0.0 )

Which wouldn't display the $wrCalm image when the wind speed was 0.0 mph and the wind gust was 0.0 mph, so I changed the code from:

Code: Select all

<?php $wr = $imagesDir . $wrName . $dirlabel . $wrType; // normal wind rose
				        $wrtext = langtransstr('Wind from') ." " . langtransstr($dirlabel);
			                        if ( (strip_units($avgspd) + strip_units($gstspd) < 0.0 )

To:

Code: Select all

<?php $wr = $imagesDir . $wrName . $dirlabel . $wrType; // normal wind rose
				        $wrtext = langtransstr('Wind from') ." " . langtransstr($dirlabel);
			                        if ( (strip_units($avgspd) + strip_units($gstspd) < 0.1 )

Then, the $wrCalm image, displayed again!
