Prevent PHP warning in upcoming.php due to wrong datatype in foreach

[Philipp Wagner <mail@…>]

At /tv/upcoming I get the following PHP warning:

---

Warning at /usr/share/mythtv/mythweb/modules/tv/upcoming.php, line 96: !NoTrans: Invalid argument supplied for foreach()!!

Warning at /usr/share/mythtv/mythweb/modules/_shared/tmpl/default/header.php, line 16: !NoTrans: Cannot modify header information - headers already sent by (output started at /usr/share/mythtv/mythweb/includes/errors.php:150)!!

---

It seems that the code tried to prevent that, but somehow it didn't get a full fix ($scheduled is unused). Trivial patch attached.

I am running 0.24.1 here, but it seems that the code is the same in the git master.

Fixing same problem in detail.php

[Philipp Wagner <mail@…>]

I just found that detail.php has the same problem; I hope it's ok to add this to this bug report, otherwise I'm happy to open a new one or attach an combined patch if that's easier for you.

Has this bug been fixed...? Tryed to change my php files but they couldend load after change.

[mail@…]

No, as far as I know the patches have not been applied. I have no idea how the process to get a patch applied is supposed to work in MythTV.

[anders@…]

What a shame...pretty irritating :P

[robertm]

irritating indeed.

Hi, The problem occurred in my new 12.04 installation today. The "fix" listed here does not correct the problem that I have. Of course it takes care of the web error, but it does not solve the real problem. It hides it. What I see is that scheduling does not work at all. I can see from the list that there are programs that the scheduler should find but it doesn't. Even the programs that were part of the scheduled recordings (visible yesterday) have disappeared. I have all the latest updates installed. Please advice if I should retrieve any information from a log.

[christian.wittrock@…]

Update... After I cleaned out some bad recordings, removed some unwanted custom schedules, added the fix and rebooted the scheduler seemed to come alive again...

Just want to report I had the same warning (NoTrans: Invalid argument supplied for foreach)in detail.php on a fresh install of MythTV 0.25-fixes and the latest MythWeb from git. Applying the patch provided by Philipp in the beginning of this ticket fixed it for me. Thanks!

[christian.wittrock@…]

Hi,

as this bug kills the scheduler and pretty much renders MythTV useless, I suggest to change the priority to critical and get the fix released.

The issue seems to occur whenever EPG data is missing from a channel, which is a common situation.

I had to re-install 12.04 because it crashed terminally, and now I have again run into this bug. So, please get this patch released.

There's no way this bug could have killed your OS...and as stated before, please keep disussions (and posts which add no value to the report), out of the report.
