I updated from PHP 5.6 to PHP 7.
every $_REQUEST['some_var'] I do returns an error that it is not set...
is it normal that $_REQUEST is empty ?
Example :
echo $_REQUEST['login_ID']
returns
Notice: Undefined index: login_ID in
Check your php.ini file for request_order. Possible it is not set correctly.
http://php.net/manual/en/ini.core.php#ini.request-order
; This directive determines which super global data (G,P,C,E & S) should
; be registered into the super global array REQUEST. If so, it also determines
; the order in which that data is registered. The values for this directive are
; specified in the same manner as the variables_order directive, EXCEPT one.
; Leaving this value empty will cause PHP to use the value set in the
; variables_order directive. It does not mean it will leave the super globals
; array REQUEST empty.
; Default Value: None
; Development Value: "GP"
; Production Value: "GP"
; http://php.net/request-order
request_order = "GP"
