If you are an existing PHPMaker user, before upgrading to v2019, please read “Migrating to v2019” first:
https://phpmaker.dev/doc/hh_goto.htm?hh_start.htm#migrate2019.htm
which says:
PHPMaker JavaScript is now under the ew namespace. The EW_ and ew_ prefixes are therefore changed to ew., e.g. EW_LANGUAGE_ID becomes ew.LANGUAGE_ID.
Method name are changed to the more common camel case, e.g. ew_SetSessionTimer() becomes ew.setSessionTimer(). If your client side code calls any PHPMaker functions, you must update them.
