indilist.php (unknown) family name generates php errors

[David Smart]

I get a bunch of these when I click on (unknown) in the Individual list.

ERROR 8: Trying to access array offset on value of type null
0 Error occurred on line 1652 of file class_person.php in function _addName
1 called from line 474 of file class_gedcomrecord.php in function _getAllNames
2 called from line 1837 of file class_person.php in function getAllNames
3 called from line 614 of file class_gedcomrecord.php in function getSortName
4 called from line 565 of file class_gedcomrecord.php in function Compare
5 called from in function usort
6 called from line 539 of file functions_db.php in function get_indilist_indis
7 called from line 278 of file indilist.php

Below this batch of errors I do see the list as expected.

As an experiment, I modified class_person.php : 1649 where I added 3 lines to trap the null.

protected function _addName($type, $full, $gedrec) {
    global $UNDERLINE_NAME_QUOTES, $NAME_REVERSE, $unknownNN, $unknownPN, $pgv_lang;

    // Look for GIVN/SURN at level n+1
    if ($gedrec == null)   // Added null guard; search for unknown family name
        $sublevel = 0;        // Added - value 0 | 1 behave the same
    else                    // Added
        $sublevel=1+(int)$gedrec[0];

I no longer see the batch of errors, but there may be a more elegant fix.

I can't reproduce this error. The problem may be caused by the way you have entered these unknown names in your database.

Please e-mail me a ZIP copy of your GEDCOM: gkroll (at) keldine (dot) ca .

Give me (in that e-mail) the Indi ID of several of those problematic records.

if ($gedrec == null) // Added null guard; search for unknown family name
$sublevel = 0; // Added - value 0 | 1 behave the same
else // Added
works for me - have the same Error with php 7.4
