Form Wizard – Multi Step Form Validation

Introduction to Form Wizard - Multi Step Form Validation

The Form Wizard is a powerful tool in Bootstrap that allows you to create multi-step forms with ease. It's a wizard-like interface that guides users through a series of steps, each with its own set of fields and validation rules. In this tutorial, we'll cover how to use the Form Wizard to create a multi-step form with validation.

Why Use the Form Wizard?

The Form Wizard is useful when you need to collect information from users in a series of steps. For example, you might use it to create a registration form that asks for basic information, then asks for payment information, and finally asks for confirmation. The Form Wizard makes it easy to manage the complexity of these forms and ensure that users complete each step before moving on to the next one.

Getting Started with the Form Wizard

To get started with the Form Wizard, you'll need to include the necessary JavaScript and CSS files in your HTML document. You can do this by adding the following lines to the head of your HTML document:

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css">
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js"></script>

Next, you'll need to create a container element for the Form Wizard. This can be a div element with the class wizard:

<div class="wizard">
  <!-- Form Wizard content will go here -->
</div>

Creating a Multi-Step Form

To create a multi-step form, you'll need to create a series of steps, each with its own set of fields and validation rules. You can do this by creating a ul element with the class nav and adding li elements for each step:

<div class="wizard">
  <ul class="nav">
    <li class="nav-item">
      <a class="nav-link active" href="#step1">Step 1</a>
    </li>
    <li class="nav-item">
      <a class="nav-link" href="#step2">Step 2</a>
    </li>
    <li class="nav-item">
      <a class="nav-link" href="#step3">Step 3</a>
    </li>
  </ul>
  <div class="tab-content">
    <div id="step1" class="tab-pane fade show active">
      <!-- Step 1 content will go here -->
    </div>
    <div id="step2" class="tab-pane fade">
      <!-- Step 2 content will go here -->
    </div>
    <div id="step3" class="tab-pane fade">
      <!-- Step 3 content will go here -->
    </div>
  </div>
</div>

Adding Fields and Validation Rules

To add fields and validation rules to each step, you'll need to create a form element within each div element with the class tab-pane. You can add fields using the input, textarea, and select elements, and validation rules using the required attribute and JavaScript validation functions.

For example, here's an example of a step with a field and validation rule:

<div id="step1" class="tab-pane fade show active">
  <form>
    <div class="form-group">
      <label for="name">Name:</label>
      <input type="text" id="name" name="name" required>
    </div>
  </form>
</div>

In this example, the name field is required and will be validated using the required attribute.

Enabling the Form Wizard

To enable the Form Wizard, you'll need to add the following JavaScript code to your HTML document:

$(document).ready(function() {
  $('#wizard').formWizard();
});

This code selects the wizard container element and calls the formWizard() method to enable the Form Wizard.

Using the Form Wizard

Once the Form Wizard is enabled, you can use it to navigate through the steps and validate the fields. You can use the navigation buttons to move forward and backward through the steps, and the Form Wizard will automatically validate the fields and prevent the user from moving on to the next step until all required fields have been completed.

Conclusion

In this tutorial, we've covered how to use the Form Wizard to create a multi-step form with validation. We've learned how to create a container element for the Form Wizard, create a series of steps, add fields and validation rules to each step, and enable the Form Wizard using JavaScript. With the Form Wizard, you can create complex forms that guide users through a series of steps and ensure that they complete each step before moving on to the next one.
