we will see how to create a simple multi-step signup form using CSS3 and jQuery. To spice up things a bit, we will include progress bar with the form, so the users will be able to see the percentage of form completion.

We will create four steps in our form:

1. username and password fields

2. first and last name and email address

3. age, gender and country

4. summary

HTML Code

First thing to do is to create the html structure. We need a box container with four divs, one for each step. The basic HTML code is the following:

<div id="container">
    <form action="#" method="post">

        <div id="first_step">
        <div id="second_step">
        <div id="third_step">
        <div id="fourth_step">

    </form>
</div>

Inside each box container we will put the fields and a simple helpfull label. You can see the code inside the first box in the code below:

<!-- #first_step -->
<div id="first_step">
    <h1>SIGN UP FOR A FREE <span>WEBEXP18</span> ACCOUNT</h1>

    <div class="form">
        <input type="text" name="username" id="username" value="username" />
        <label for="username">At least 4 characters. Uppercase letters, lowercase letters and numbers only.</label>

        <input type="password" name="password" id="password" value="password" />
        <label for="password">At least 4 characters. Use a mix of upper and lowercase for a strong password.</label>

        <input type="password" name="cpassword" id="cpassword" value="password" />
        <label for="cpassword">If your passwords aren’t equal, you won’t be able to continue with signup.</label>
    </div>      <!-- clearfix --><div class="clear"></div><!-- /clearfix -->
    <input class="submit" type="submit" name="submit_first" id="submit_first" value="" />
</div>      <!-- clearfix --><div class="clear"></div><!-- /clearfix -->

We have used three input fields: username, password and confirm password and at the end of the box, an input submit for the next step. The other boxes work in the same way.

At the end of the container box you can see a simple progress bar. This is the necessary code:

<div id="progress_bar">
    <div id="progress"></div>
    <div id="progress_text">0% Complete</div>
</div>

The complete HTML code is the following:

<div id="container">
        <form action="#" method="post">

            <!-- #first_step -->
            <div id="first_step">
                <h1>SIGN UP FOR A FREE <span>WEBEXP18</span> ACCOUNT</h1>

                <div class="form">
                    <input type="text" name="username" id="username" value="username" />
                    <label for="username">At least 4 characters. Uppercase letters, lowercase letters and numbers only.</label>

                    <input type="password" name="password" id="password" value="password" />
                    <label for="password">At least 4 characters. Use a mix of upper and lowercase for a strong password.</label>

                    <input type="password" name="cpassword" id="cpassword" value="password" />
                    <label for="cpassword">If your passwords aren’t equal, you won’t be able to continue with signup.</label>
                </div>      <!-- clearfix --><div class="clear"></div><!-- /clearfix -->

            <!-- #second_step -->
            <div id="second_step">

                <div class="form">

                    <label for="firstname">Your First Name. </label>
                    <input type="text" name="lastname" id="lastname" value="last name" />
                    <label for="lastname">Your Last Name. </label>
                    <input type="text" name="email" id="email" value="email address" />
                    <label for="email">Your email address. We send important administration notices to this address</label>

                        <tr><td>Country</td><td></td></tr>

        </form>

            <div id="progress"></div>
            <div id="progress_text">0% Complete</div>
	</div>

As you can see, in the fourth step the table is empty. We fill it with the information entered by the users using jQuery.

CSS Code

Now we need to add the style on the form. First, we use the @fontface rule for using a custom font. I’ve used the Cantarell font. The complete CSS Code is listed below:

jQuery Code

We’re going to use jQuery for:

- slide the steps

- check if the data are valid

- change the completion percentage of progress bar

We need load jQuery library inside the page and then to use two plugins:

- jQuery UI, the most famous plugin used to extend the jQuery functionality.

- jQuery inputfocus, my jQuery plugin used to manage focus and blur events of the form.

Our jQuery code is listed below:

$(function(){
    //original field values
    var field_values = {
            //id        :  value
            'username'  : 'username',
            'password'  : 'password',
            'cpassword' : 'password',
            'firstname'  : 'first name',
            'lastname'  : 'last name',
            'email'  : 'email address'
    };

    //inputfocus
    $('input#username').inputfocus({ value: field_values['username'] });
    $('input#password').inputfocus({ value: field_values['password'] });
    $('input#cpassword').inputfocus({ value: field_values['cpassword'] });
    $('input#lastname').inputfocus({ value: field_values['lastname'] });
    $('input#firstname').inputfocus({ value: field_values['firstname'] });
    $('input#email').inputfocus({ value: field_values['email'] });

    //reset progress bar
    $('#progress').css('width','0');
    $('#progress_text').html('0% Complete');

    //first_step
    $('form').submit(function(){ return false; });
    $('#submit_first').click(function(){
        //remove classes
        $('#first_step input').removeClass('error').removeClass('valid');

        //ckeck if inputs aren't empty
        var fields = $('#first_step input[type=text], #first_step input[type=password]');
        var error = 0;
        fields.each(function(){
            var value = $(this).val();
            if( value.length<4 || value==field_values[$(this).attr('id')] ) {
                $(this).addClass('error');
                $(this).effect("shake", { times:3 }, 50);

                error++;
            } else {
                $(this).addClass('valid');
            }
        });

        if(!error) {
            if( $('#password').val() != $('#cpassword').val() ) {
                    $('#first_step input[type=password]').each(function(){
                        $(this).removeClass('valid').addClass('error');
                        $(this).effect("shake", { times:3 }, 50);
                    });

                    return false;
            } else {
                //update progress bar
                $('#progress_text').html('33% Complete');
                $('#progress').css('width','113px');

                //slide steps
                $('#first_step').slideUp();
                $('#second_step').slideDown();
            }
        } else return false;
    });

    $('#submit_second').click(function(){
        //remove classes
        $('#second_step input').removeClass('error').removeClass('valid');

        var emailPattern = /^[a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$/;
        var fields = $('#second_step input[type=text]');
        var error = 0;
        fields.each(function(){
            var value = $(this).val();
            if( value.length<1 || value==field_values[$(this).attr('id')] || ( $(this).attr('id')=='email' && !emailPattern.test(value) ) ) {
                $(this).addClass('error');
                $(this).effect("shake", { times:3 }, 50);

                error++;
            } else {
                $(this).addClass('valid');
            }
        });

        if(!error) {
                //update progress bar
                $('#progress_text').html('66% Complete');
                $('#progress').css('width','226px');

                //slide steps
                $('#second_step').slideUp();
                $('#third_step').slideDown();
        } else return false;

    });

    $('#submit_third').click(function(){
        //update progress bar
        $('#progress_text').html('100% Complete');
        $('#progress').css('width','339px');

        //prepare the fourth step
        var fields = new Array(
            $('#username').val(),
            $('#password').val(),
            $('#email').val(),
            $('#firstname').val() + ' ' + $('#lastname').val(),
            $('#age').val(),
            $('#gender').val(),
            $('#country').val()
        );
        var tr = $('#fourth_step tr');
        tr.each(function(){
            //alert( fields[$(this).index()] )
            $(this).children('td:nth-child(2)').html(fields[$(this).index()]);
        });

        //slide steps
        $('#third_step').slideUp();
        $('#fourth_step').slideDown();
    });

    $('#submit_fourth').click(function(){
        //send information to server
        alert('Data sent');
    });

});

The code from row 3 to 20 activate the inputfocus plugin to each input field. The code from row 27 to 64 check the validity of the data entered by the user (if username and password length is greather than 4 characters, if the password and confirm password fields are equal), then update the progress bar value and then slide to second step.

The code from row 71 to 100 check the data integrity for the second step (if first and last name aren’t empty and if the email address is valid). The rest is similar to the previous code.

Conclusions

We have seen how simple its to create a multistep signup form. This is only an example so I omitted some features as back button, and more others. Anyway the example is ready to use and it needs only to change the form action with the link of your php file used to store data and to edit the jQuery line 125 to: $(‘form’).unbind(‘submit’).submit();. You can also decide to use an AJAX calls to send the informations to server, and again it’s very easy to implement.
