Modal display when submitting form. Without loading the page

I have the code below. I would like to display a modal once I submit the form and if all fields are filled out. If any field has not been filled it is already showing a popover in the field indicating that it is wrong. Thank you for your contribution. 

<form id="form" role="form" method="post" action="<?php echo $_SERVER['REQUEST_URI']; ?>">
                    <div class="form-group">
                      <label for="nome_empresa">
                        Nome da empresa
                      </label>
                      <input type="text" placeholder="Nome da empresa" id="nome_empresa" name="nome_empresa" class="form-control required body" data-placement="right" data-trigger="manual" data-content="Possível erro">
                    </div>
                    <div class="form-group">

I would add the required="required" attribute in all fields.

To validate on the back end, it would do an ajax check. If there are blank fields, it would return the error in real-time.

You can do something in jQuery too: 

$("#campo").blur(function(){
  var valor = $("#campo").val();
  if (valor == null)
    $("#erro").html("Campo xyz obrigatório não preenchido.");
});
