Multi steps form is a very useful functionality when the user input data is too much and needs to divide into parts.

Simple Example of Multi step form Using jQuery and Bootstrap

Lets create multi step form using bootstrap.

Step 1: We will create index.php file, where we need to test this sample example. I need to include jQuery and bootstrap library files into the head section of index.php file.

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>

Here i am using cdn path for jquery and bootstrap. You can also use these library locally and replace with your path.

Step 2: Creating HTML UI for all steps which you need in multi step form to follow user and added into index.php file.

<div class="progress">
    <div class="progress-bar progress-bar-striped active" role="progressbar" aria-valuemin="0" aria-valuemax="100"></div>
  </div>
  <form id="regiration_form" novalidate action="action.php"  method="post">
  <fieldset>
    <h2>Step 1: Create your account</h2>
    <div class="form-group">
    <label for="email">Email address</label>
    <input type="email" class="form-control" id="email" name="email" placeholder="Email">
    </div>
    <div class="form-group">
    <label for="exampleInputPassword1">Password</label>
    <input type="password" class="form-control" id="password" placeholder="Password">
    </div>
    <input type="button" name="password" class="next btn btn-info" value="Next" />
  </fieldset>
  <fieldset>
    <h2> Step 2: Add Personnel Details</h2>
    <div class="form-group">
    <label for="fName">First Name</label>
    <input type="text" class="form-control" name="fName" id="fName" placeholder="First Name">
    </div>
    <div class="form-group">
    <label for="lName">Last Name</label>
    <input type="text" class="form-control" name="lName" id="lName" placeholder="Last Name">
    </div>
    <input type="button" name="previous" class="previous btn btn-default" value="Previous" />
    <input type="button" name="next" class="next btn btn-info" value="Next" />
  </fieldset>
  <fieldset>
    <h2>Step 3: Contact Information</h2>
    <div class="form-group">
    <label for="mob">Mobile Number</label>
    <input type="text" class="form-control" id="mob" placeholder="Mobile Number">
    </div>
    <div class="form-group">
    <label for="address">Address</label>
    <textarea  class="form-control" name="address" placeholder="Communication Address"></textarea>
    </div>
    <input type="button" name="previous" class="previous btn btn-default" value="Previous" />
    <input type="submit" name="submit" class="submit btn btn-success" value="Submit" />
  </fieldset>
  </form>

I have created 3 steps using HTML field-set control for each step, So whenever user click next and previous button. We will slide fieldset based on current step.

Step 3: Add css class into section of index.php file to hide other steps except first step.

<style type="text/css">
  #regiration_form fieldset:not(:first-of-type) {
    display: none;
  }
  </style>

Step 4: We will use jQuery to hide and show HTML fieldset for navigation between steps,You need to add below code into footer of index.php file.

$(document).ready(function(){
  var current = 1,current_step,next_step,steps;
  steps = $("fieldset").length;
  $(".next").click(function(){
    current_step = $(this).parent();
    next_step = $(this).parent().next();
    next_step.show();
    current_step.hide();
    setProgressBar(++current);
  });
  $(".previous").click(function(){
    current_step = $(this).parent();
    next_step = $(this).parent().prev();
    next_step.show();
    current_step.hide();
    setProgressBar(--current);
  });
  setProgressBar(current);
  // Change progress bar action
  function setProgressBar(curStep){
    var percent = parseFloat(100 / steps) * curStep;
    percent = percent.toFixed();
    $(".progress-bar")
      .css("width",percent+"%")
      .html(percent+"%");   
  }
});

Step 5: Created action.php file and added below code into this file.

<div class="row well alert alert-success"><?php echo "<pre>";print_R($_POST);?></div>

So after completion of all steps user will click submit button. We will post all steps data and send to action.php file using the form action attribute.
