Session flashdata

[florent6001]

How can i do this, with this twig template engine please ?

  <?php if($this->session->flashdata('category_created')): ?>
    <?php echo '<p class="alert alert-success">'.$this->session->flashdata('category_created').'</p>'; ?>
  <?php endif; ?>

Something like this should work:

{% if session.flashdata.category_created is not empty %}
    <p class="alert alert-success">{{ session.flashdata.category_created }}</p>
{% endif %}
