Pull Request for Issue #40680 .

Summary of Changes

This pull request (PR) fixes the PHP warnings reported in the linked issue when installing Blog Sample Data by adding an isset check.

In addition it fixes PHP Warning: Undefined array key "searchindex" in /administrator/components/com_fields/src/Model/FieldModel.php on line 886 happening when publishing or unpublishing a field which doesn't have the "searchindex" parameter set, e.g. when having updated from 4.4 and not saved the field again, or when having installed Blog Sample Data without that parameter.

This is one possible way to fix the issue, but it might be not the best way.

@Hackwar Please check. I have tested and it works, but as said, it might be the wrong way to fix it. But keep in mind that when updating from 4.4 and not having a migration for the fields parameters, we always might run into the new parameter not being set.

Testing Instructions

On a clean, current 5.0-dev branch where PR #38650 has been merged, make a new installation.

Then login to backend.

Then either set error reporting to maximum or make sure that PHP warnings are logged into a log file.
