fix 'undefined index' notice when testing for checkboxes

[stepmuel]

Small fix to get rid of some annoying PHP warnings when submitting the settings panel form…

That makes sense for checkboxes. Worth nothing that the equivalent to (boolean) would be !empty() instead of isset(). Example: Radio buttons with values of 1 and 0.

Hello, I have tested this correction and it looks like it is still there is still a error (but likely minor).

I see the error "Undefined index: managed in..." when the fields are unamanaged.

Maybe a conflict with #21 that I also have merged in my fork that has a small changed related to managed fields.

I will give it a second look and report if this can be useful.

The problem is there :

checked($shib_headers['first_name']['managed'], 'on')

When the value is unchecked, 'managed' key (index) doesnt exist.

This is what I have done to correct it: https://github.com/devanonyme/shibboleth/commit/da436adb8c5a91210aa14c4c9a5ac9e96d7bcb2c

@DevAnonyme I'm unable to reproduce the undefined index error that you've received. If you can pull down a copy of my repo with these PRs applied and let me know if you still see the error, I'd appreciate it. (I know this has been a while, so you may no longer be interested in this fix.)

I will take a note to test it but it will be on a (very) slow track as I'm currently assigned to another project.
Thanks!

I did the test with a few combination (keyname + unmanaged, keyname + managed, no key + unmanaged, no key + managed) and I was not able to reproduce the problem with your version. I noticed that the difference with your version
aside the error handler with the other fix I had merged (https://github.com/devanonyme/shibboleth/commit/c763a49f44f81b2f814c57f0f51203ba384c0d76) was the use of !empty instead of isset, I guess the table of truth is not exactly the same... I probably didn't noticed that at the time and tried to fix it at the symptom level instead of the root.

Excellent news, thanks @DevAnonyme. Just wanted to make sure that I wasn't missing a test case in my changes.

Thanks!

I think I had a problem with (federated) logout but I think there where no generic solution to this one. Other than that the plugin is doing the job that we need just fine.

Thanks also for taking the responsability of maintenance.
