Need help with eregi function ^^

[Zimi]

Hello

I'm trying to use the eregi function to make sure a string entered by the user is valid (only English letters, numbers, "_" and "-".

This is my first time using eregi and regular expressions so I have no idea what's the problem with my code:

 

function Vaild_Login($Login_Name)
{
if(eregi('[^A-Za-z0-9_-]', $Login_Name))
{
return True;
}
else
{
return False;
}
}

 

Any help would be appraised ^^

You put the ^ inside of a character class, making it mean "not".  Try this:

 

^[A-Za-z0-9_-]$

Fast replay lol, thanks ^^

But still not working, the code looks like this:

function Vaild_Login($Login_Name)
{
if(eregi("^[A-Za-z0-9_-]$", $Login_Name))
{
return True;
}
else
{
return False;
}
}

And the other end:

if(Vaild_Login($Login_Name) == False && $Login_name != "")
	{
	echo "You have submitted an invaild Login Name";
                }
