How to access the fields from the form data in symfony 3 -

i want use how access username , password fields below code.

appbundle\entity\masteruseraccount object (     [id:appbundle\entity\masteruseraccount:private] =>      [firstname:appbundle\entity\masteruseraccount:private] =>      [lastname:appbundle\entity\masteruseraccount:private] =>      [username:appbundle\entity\masteruseraccount:private] => test     [password:appbundle\entity\masteruseraccount:private] => 123456     [createdby:appbundle\entity\masteruseraccount:private] =>      [updatedby:appbundle\entity\masteruseraccount:private] =>      [createdat:appbundle\entity\masteruseraccount:private] =>      [updatedat:appbundle\entity\masteruseraccount:private] =>      [status:appbundle\entity\masteruseraccount:private] =>  )  $data = $form->getdata();  $username = $data['username']; 

i'm getting below error following error

cannot use object of type appbundle\entity\classname array

the data out of symfony form entity. can't access attribute of entity, arrays.

instead should using getter method defined inside class masteruseraccount.

so. should be:

$username = $data -> getusername(); 

this assuming getter method defined inside masteruseraccount class. if not, create getter method first.
