Regex help for contact form

[davelearning]

Hi all,

 

No matter what username I enter, I am receiving the invalid username message:

$(function() {

// load the modal window
$('a.modal').click(function(){

	// scroll to top
	$('html, body').animate({scrollTop:0}, 'fast');

	// before showing the modal window, reset the form incase of previous use.
	$('.success, .error').hide();
	$('form#contactForm').show();

	// Reset all the default values in the form fields
	$('#name').val('Your name');
	$('#email').val('Your email address');
	$('#comment').val('Enter your comment or query...');

	//show the mask and contact divs
	$('#mask').show().fadeTo('', 0.7);
	$('div#contact').fadeIn();

	// stop the modal link from doing its default action
	return false;
});

// close the modal window is close div or mask div are clicked.
$('div#close, div#mask').click(function() {
	$('div#contact, div#mask').stop().fadeOut('slow');

});

$('#contactForm input').focus(function() {
	$(this).val(' ');
});

$('#contactForm textarea').focus(function() {
        $(this).val('');
    });

// when the Submit button is clicked...
$('input#submit').click(function() {
$('.error').hide().remove();
	//Inputed Strings
	var name = $('#name').val(),
		email = $('#email').val(),
		comment = $('#comment').val();


	//Error Count
	var error_count;

	//Regex Strings
	var name_regex =  /^[a-z0-9_-]{3,15}$/,
		email_regex = /^([a-z0-9_\.-]+)@([\da-z\.-]+)\.([a-z\.]{2,6})$/;

		//Test Username
		if(!name_regex.test(name)) {
			$('#contact_header').after('<p class=error>Invalid username entered!</p>');
			error_count += 1;
		}

		//Test Email
		if(!email_regex.test(email)) {
			$('#contact_header').after('<p class=error>Invalid email entered!</p>');
			error_count += 1;
		}

		//Blank Comment?
		if(comment == '') {
			$('#contact_header').after('<p class=error>No Comment was entered!</p>');
			error_count += 1;
		}

		//No Errors?
		if(error_count === 0) {
			$.ajax({
				type: "post",
				url: "scripts/send.php",
				data: "name=" + name + "&email=" + email + "&comment=" + comment,
				error: function() {
					$('.error').hide();
					$('#sendError').slideDown('slow');
				},
				success: function () {
					$('.error').hide();
					$('.success').slideDown('slow');
					$('form#contactForm').fadeOut('slow');
				}				
			});	
		}

		else {
                $('.error').show();
            }

	return false;
});

});

I copied your regex code and it seems to work okay.

Here's the url where I tested it http://www.realtown.com/test40.php

Ahhh think I have it, if you enter a uppercase letter it fails!

 

Thanks for checking it, its put me in the right direction
