So, on the first frame we need to add some code, mainly for the textboxes. 1) we need to resrict the input type of the username and password text box and display an appropriate status to the user.

So, on the first frame add this code:

stop()
userinput.restrict="a-zA-Z0-9";
Selection.setFocus(userinput);
passinput.restrict="a-zA-Z0-9";

Here we restrict the userinput instanced text box to allow any character from a-z A-Z and 0-9. The same goes for the password box, and we also set a focus on the userinput box so the user can type as soon as it loads…

But this isn’t enough so add this…

if(_root.justReg != true){
	status="Enter your information and submit";
}else{
	status="Registration successful, Enter your information and submit"
}
_root.onEnterFrame = function(){
	if(_root.log == 1){
		status="Success"
		_root.userId = user
		_root.justReg = false
		_root.gotoAndStop(3);
	}
	if(_root.log == 2){
		status="Error, your information is incorrect..."
		_root.justReg = false
	}
}

Now we are checking if they have just registered, if so display the appropriate message if not then the other. Then we are checking the _root.log variable but we haven’t declared it yet.

So – on the submit button add this…

on(release, keyPress "<Enter>") {
	if (user != "" && pass != "") {
		status = "Starting Login Process - Please Wait...";
		loadVariablesNum("login.php", 0, "POST");
	}
}

Notice that here we use the release of the button or Enter for efficiency and then we check to see that the variables are populated. These variables are connected to the text boxes as shown below…

Then we set a status while the data is sent to the login.php file with the variables in the root via the POST mechanism. We use loadVariablesNum so that we can easily receive a response from the server…
