Submit form in modal bootstrap window, and update window with submitted information

Question

Good morning! Guys, my difficulty is the following: I have a modal window, where I load a list from the bank, display it to the user, and there is a field where there is an edition, where I created a form, and from there I update it in my database. The edition works perfectly, my only problem at the moment is, once the information is updated in the bank, I wanted the page of this refresh on the page and already open the modal in which the edition is made. Not put code because I did nothing related for lack of content or knowledge in the subject. Thank you for your attention.

Considering that your page refreshes, in this case it is enough that the php file that processes the form returns a parameter to the page.

You can do it two ways: Via $_GET or Via $_SESSION

• VIA $_GET :

Just pass the parameter via URL:

Page processing the form:

if ($atualiza == true){
    header('location:pagina.php?sucesso=1');
}

Modal page

<div id="myModal" class="modal fade <?=((isset($_GET['sucesso']))?'visivel':'')?>" role="dialog">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">...</div>
      <div class="modal-body">...</div>
      <div class="modal-footer">...</div>
    </div>
  </div>
</div>

• VIA $_SESSION:

Just create a message variable and arrow it:

if ($atualiza == true){
    session_start();
    $_SESSION['sucesso'] = 1;
}

Modal page:

<?php session_start();?>
<div id="myModal" class="modal fade <?=((isset($_SESSION['sucesso']))?'visivel':'')?>" role="dialog">
      <div class="modal-dialog">
        <div class="modal-content">
          <div class="modal-header">...</div>
          <div class="modal-body">...</div>
          <div class="modal-footer">...</div>
        </div>
      </div>
    </div>
<!--Se a página não trabalha com sessões, você pode destruir a sessão após exibir a mensagem-->
<?php session_destroy();?>
<!--Se a página usa sessão pra outras coisas, ou se no fluxo da aplicação tem outros momentos que a sessão será utilizada após passar por essa página, nesse caso basta limpar o campo da mensagem-->
<?php unset($_SESSION['sucesso']);?>

finally it is enough that your css displays the modal when the class .visivel was set:

.visivel{
  display:block;
}
