Those are from the last 3 lines in

Code: Select all

  preg_match_all('|(\d+)|is',$WDmoonage,$matches);
//  print "<!-- matches=\n" . print_r($matches,true) . "-->\n";
  $mdays = $matches[1][0];
  $mhours = $matches[1][1];
  $mmins = $matches[1][2];
  $mpct  = $matches[1][3];
The call to the function happens in
Line 859: alt="<?php $t1 = moonphase($moonage) . ", Moon at $moonagedays days in cycle";

The $moonage value is constructed by

Line 300: if(!isset($moonage)) {$moonage = 'Moon age: '.$mooninfo->age.','.$mooninfo->ill.'%'; }

if it is missing from the CUdefs.php file (which it normally is).

The cMooninfo is returning
<!-- cGetMoonInfo returns
stdClass Object
(
[date] => 1566008403
[datetxt] => Sat, 17-Aug-2019 02:20 GMT
[age] => 15 days, 23 hours, 8 minutes
[ill] => 98
[pic] => 15
[phase] => Waning Gibbous
so $moonage should contain 'Moon age: 15 days, 23 hours, 8 minutes,98%' so the

preg_match_all('|(\d+)|is'

should pick up the 4 number values from that string.
I suggest you change the

Code: Select all

//  print "<!-- matches=\n" . print_r($matches,true) . "-->\n";
to

Code: Select all

  print "<!-- WDmoonage='$WDmoonage', matches=\n" . print_r($matches,true) . "-->\n";
so the argument and results can be seen in a view-source of the page.

Thanks Ken,
I have made the edit. Lines 1177 to 1187 are now

Code: Select all

// "Moon age: 10 days,10 hours,41 minutes,80%"

function moonphase ($WDmoonage) {

  preg_match_all('|(\d+)|is',$WDmoonage,$matches);

print "<!-- WDmoonage='$WDmoonage', matches=\n" . print_r($matches,true) . "-->\n";
  $mdays = $matches[1][0];
  $mhours = $matches[1][1];
  $mmins = $matches[1][2];
  $mpct  = $matches[1][3];
but still get the same in the error_log -
[19-Aug-2019 00:15:26 America/Toronto] PHP Notice: Undefined offset: 1 in /home/psoykkrhjuz3/public_html/komokaweather-ca/ajax-dashboard.php on line 1185

I have made a slight modification to ajax-dashboard.php to display the Sager forecast, and presume that has not impacted the error message?

Regards,
Paul

The view-source of the page now shows
<!-- WDmoonage='18', matches=
Array
(
[0] => Array
(
[0] => 18
)

[1] => Array
(
[0] => 18
)

)
-->
so the $moonage string passed to it is not in the expected form (missing the hours seconds and % illumination values).

Check your site for anything that might set $moonage variable (a mod perhaps).
