problem 1 : [ //1 ] what is the operator for OR , in this case I have used the condition for if the pass or user is blank,but the OR is not working neither || , used in javascript.
problem 2 : [ //2 ] if die is used , then the statement is printed in the new window , but I want it to appear in the same window...I also used echo, it worked but I feel like i am missing the main function of 'die' by using 'echo'.
problem 3 : [ \[code\]<!--3-->\[/code\] ] how can I replace signup.php as action to something like SERVER_PAGE or whatever...
