i know kind of question has been posted lot in stack overflow still couldn't solve problem. that's why ask again here, 1 can me.
below code persist user class:
$package = $em->getrepository('mybundle:package')->findoneby(array('id' => 1)); $new_user->addpackage($package); $role = $em->getrepository('mybundle:role')->findoneby(array('id' => 3)); $new_user->addrole($role); $new_user->setcmsprize(2); //int $new_user->setcmsbet(3); //int $new_user->setname("new user"); $new_user->setusername("test123"); $new_user->setpassword("abc"); $new_user->setcreditlimit(1000); $new_user->setcreditbalance(2000); $new_user->setselectedpackage($currentuser->getselectedpackage()); $new_user->setparentid($currentuser->getid()); $new_user->setlayer($currentuser->getlayer() + 1); $em->persist($new_user); $em->flush(); below user class:

the error log:
critical - uncaught php exception symfony\component\debug\exception\contexterrorexception: "warning: spl_object_hash() expects parameter 1 object, integer given" @ c:\xampp\htdocs\project\vendor\doctrine\orm\lib\doctrine\orm\unitofwork.php line 1389
the different thing can see data type of $child, $roles , $packages variable. make different? variable child didn't set because not belong variable database. self-referencing usage, $parent_id has self-referencing relationship $child set $parent_id.
i got no idea, maybe have wrong concept self-referencing.
thank your help.
looking @ annotations, guess user::setparentid() expecting user object, not integer:
/** * @orm\manytoone(targetentity="user", inversedby="children") * @orm\joincolumn(name="parent_id", referencedcolumnname="id", nullable=true) * */ so instead of passing
$new_user->setparentid($currentuser->getid()); try:
$new_user->setparentid($currentuser); if works, field name should changed appropriately parent instead of parent_id.
