You're missing quotes around a constant. Where you have
$query = " UPDATE wentwrong SET descr=$descr, /*wrong*/
you should have
$query = " UPDATE wentwrong SET descr='$descr',
The tricks to troubleshooting this kind of thing.
read error messages carefully. Then read them again.
believe the error messages. You're working with systems that have been around for a couple of decades. They aren't throwing random bogus errors any more.
In the case of MySQL's syntax error message, it shows you the erroneous query, starting with the first character it could not understand.
