Did the following steps have sense in securing my login process?
SESSION1 = random()
SESSION2 = random()
SESSION3 = random()
SESSION4 = time()
SESSIONHASHKEY = array(){[SESSION1 digits]};
SESSIONRESULT = hash(Concatenation of caracters at position  situated inside the SESSIONHASHKEY array from the SESSION2);
Set the name of the button of the login to the SESSION3 number)

if !isset SESSION1 redirect login page
if !isset SESSION2 redirect login page
if !isset SESSION3 redirect login page
if !isset SESSION4 redirect login page

if SESSION1 digits array != SESSIONHASHKEY redirect loginpage
if MD5(concatenation of caracters at position situated inside the SESSIONHASHKEY) != SESSIONRESULT redirect loginpage

if !isset loginbutton_{SHA256(MD5(SHA256(MD5(SHA256(SESSION3)))))} redirect login page
if (time() - SESSION4) >10 redirect loginpage
