how and where to record data in a session on octobercms

Question

I would like to record the data of a form in a session

I find in the documentation that I have to use: Session::put('key', 'value'); but I do not know where to place this piece of code.

knowing that my form is located in the form_commun_1.htm page.

this is all the page :

title = "formulaire_commun_1"
url = "/formulaire_commun_1"
layout = "sidebar_layout"
is_hidden = 0
==





 <ul class="progressbar">
 <li class="active">transaction</li>
 <li>details</li>
 <li>confirmation</li>
 </ul>

 <form method="POST" action=""  name="formu" accept-charset="UTF8"  enctype="multipart/form-data">
        <input type="hidden" name="_handler" value="onUpdate">
                {{form_token()}}
                {{form_sessionkey()}}
<div class="form-group">
  <label for="TYPE_transaction" class="col-sm-3">type de transaction:</label>
   <div class="col-sm-9">
     <select class="form-control" id="TYPE_transaction">
    <option>vendre</option>
    <option>louer</option>

  </select>
    </div>

do I have to go through creating a plugin or component ? and where to put the session and how to use it?

please help?thank you

Answer 1

I would recommend creating a plugin and component, but this isn't 100% necessary in your case.

Here would be a basic self-contained page that would do what you are requesting:

title = "test"
url = "/test"
layout = "default"
is_hidden = 0
==
<?php
function onStart()
{
    $this['example'] = Session::get('example-key');
}

function onTest()
{
    Session::put('example-key', input('my-input'));
}

?>
==

<form data-request="onTest" data-request-success="location.reload();">
    <input type="text" name="my-input">
    <button type="submit">Submit</button>
</form>

{% if example %}
    <strong>Example: {{ example }}</strong>
{% endif %}

I would recommend reading through the OctoberCMS documentation, it is excellent.
