Just wondering if anyone accepts cheap bribes or "Donations" to take a quick look at how something works. Oh, and possibly fix it..... Involves Java & Php. It's simply the pop-up on my weather site. Apparently you just upload a few libraries that generate graph images that pop up as tool tips. The png is supposed to be generated on the server side, from Json files, which in my case appear to be present & constantly being updated. Mine popup, but the png files have never updated. It's all just a field that I have no experience in, & am totally lost. Thanks Phil. Weather page is here. |

Could be a simple cache problem. Maybe the PNG files are been generated, but have the same file name as the old file, and you web server or your browser doesn't think the files are new, so sends/displays a cached copy of the image. If this is the case, in your html you can use a trick to make the server/browser look for the new file. As an example, I have a php page that displays a graph, this graph is freshly generated by the php each time the page is run, but uses the same file name for the image each time. So to force the server/browser to display th enew image, I use... <img src="TempImages/QGraph.gif?x=<?= time() ?>" width="450" height="212"> This more or less ads a unique number to the value of x, passed as part of the image source ( src= ).

Hi Glenn, No, My problem is that I'm not even generating new images. The one's it is showing are static since the installation upgrade back in September. They are in /public_html/weather/images/ There's also copies up in /public_html/weather/, but I know they are just there from the Cumulus 1 days & can be deleted. (Gone now, mid post). So my problem is I don't understand enough about how the setup the scripts that create the current images in weather/images. Mostly I think I's just me not understanding the setting up process, wrong lingo etc. Phil. This is the simple explanation.... Gauge-Graphs |
