Topic: Propagation feature not working

[BKS97]

The propagation feature on my wxradio page does not work,  I have tried the several fixes offered in this thread from last July to no avail:
https://www.wxforum.net/index.php?topic=45535

I reloaded the wxradio-V3.07 script including NWR-radios.js and refreshed the cache but no luck.  Any suggestions appreciated.  Thanks, Bill

It looks like you are missing the NWR-coverage.php script on your website -- it's returning a 404-Not Found.
That script provides the data used for the coverage and propagation displays in the map.

[BKS97]

Thanks for taking a look, Ken. The NWR-coverage.php file actually is there along with the other radio files.  I tried deleting then reloading the file, but it still returns the 404-Not Found, as you have discovered.  However, the other NWR files do show properly when called for with no 404 error.  The radio page works properly but the NWR-coverage.php file acts as if it is not there.

Ok, you have a tough problem to solve.

Please install this update for the NWR-coverage.php -- it has additional diagnostic functions.
https://saratoga-weather.org/wxtemplates/USA/NWR-coverage.php?sce=view

Let me know when it's installed and I'll try additional debugging.

[BKS97]

Ken, the NWR-coverage.php update is now installed.

[saratogaWX]

Thanks.. it's very strange.  What I'd expect to see with the debug enabled is

Code: [Select]

so it's missing all the curl statistics.

Can you check the error_log for the site and look for PHP errors for NWS-coverage.php script?

Also, add to the top of the NWR-coverage.php script (just after the opening <?

Code: [Select]

error_reporting(E_ALL);
ini_set('display_errors','1');


[BKS97]

I made the addition to the top of the NWR-coverage.php script as you requested.  Then, in checking the error_log for the script, this is what came up:

error_reporting(E_ALL); ini_set('display_errors','1');
Warning: session_start(): Session cannot be started after headers have already been sent in /home/sartelleast/www/www/Settings.php on line 378

Warning: Cannot modify header information - headers already sent by (output started at /home/sartelleast/www/www/NWR-coverage.php:1) in /home/sartelleast/www/www/NWR-coverage.php on line 141

[saratogaWX]

Ok, we're getting closer.

Put

Code: [Select]

error_reporting(E_ALL);
ini_set('display_errors','1');
  AFTER the opening <?php in the script.

Then, try changing your WD c:\wdisplay\webfiles\testtags.txt and delete the closing ?> line at the end.  There appears to be a space after that and it's causing headers to be emitted early.

If that doesn't fix the issue (but you should leave it that way anyway), then try changing NWS-coverage.php from

Code: [Select]

  $cacheFileDir = './';   // default cache file directory
to

Code: [Select]

  $cacheFileDir = './cache/';   // default cache file directory
and

Code: [Select]

if (isset($SITE['cacheFileDir']))    {$cacheFileDir = $SITE['cacheFileDir']; }
to

Code: [Select]

# if (isset($SITE['cacheFileDir']))    {$cacheFileDir = $SITE['cacheFileDir']; }
to comment out include of Settings.php althogether.

[BKS97]

The testtags.php file on my site has this at the end:

// end of other addons
// end of testtags.txt/testtags.php
?>

Is this the ?> closing that I should delete?

[saratogaWX]

Yes

[saratogaWX]

I've updated the NWR-coverage,php with even more diagnostics.
Please download from here and upload to your site and let me know when it's available.

Thanks...

[BKS97]

Thank you, Ken.  The updated NWR-coverage.php file is now in place.

[saratogaWX]

Ok, update it once more.

Also use your FTP program to change the permissions on NWR-radios-data.js to 755 so it can be written.  You have a very old version of that file
which is supposed to be updated by NWR-radios-data.php automatically, but somehow, it is not being updated.
After you change the permissions on NWR-radios-data.js, run NWR-radios-data.php?cache to manually update the cache.

[saratogaWX]

Also try this update for NWR-radios-data.php from here

[BKS97]

Ken: That was the trick.  The propagation feature now works.  Thank you very much for all your time and trouble.  I much appreciate your great help.  --Bill

[saratogaWX]

Whew!  I was running out of ideas, so I'm glad the last one finally worked.

[saratogaWX]

I've updated the radio script set to V3.08 with those updates.

Download from the script page or GitHub.
I do urge all users of the wxradio.php script set to update .. it fixes an issue to get the current noaaweatherradio.org radios available file.
