When storing entity objects in the http session, you might run into following exception :
ErrorException: Notice: serialize() [function.serialize]: “id” returned as member variable from __sleep() but does not exist in…
Now, apparently php has some problems serializing an object which subclasses an object with private properties. As Doctrine always creates subclasses of your entity classes (which are called Proxy classes), this means you should never use private properties (e.g. $id or any other property) on your entity (or associated entities) ! Use protected instead.
Thanks a lot !
Many thanks, this was driving me nuts! A quick
for f in $(find . -name “*.php”); do cp $f $f.bkp; sed -e ‘s/private \$/protected \$/g’ $f; rm $f.bkp; done
did the trick for me then.
Thanks again!
