Issue resolved!
It turned out to be the use of quotations. Instead of double quotations to
surround the $insert variable, it worked with single quotations:
$insert = ' INSERT INTO user_info
(login,password)
VALUES
("'.$login.'", "'.$password.'") ' ;
With the real_escape_string, this version worked (double quotation on the
outside, single quotation on the inside):
( " '.mysql_real_escape_string($login).' ", "
'.mysql_real_escape_string($password).' ")';
I'm not sure why the use of quotations works differently in different cases?
Thanks for your insights! It really helped with diagnostics. Much
appreciated!
