Sf/Twig - count number of property with same value - symfony

Question

I just want to display on a twig view the number of a property with a value defined like
<div class="list-group">
{% for ticket in tickets %}
{% if ticket.statut == 'En attente' %}
{{ loop.index }}
{{ ticket.statut }}
<div class="d-flex justify-content-start"><i class="fas fa-ticket-alt"></i> {{ ticket.getNomProduit }}</div>
{% endif %}
{% endfor %}
</div>
but i got the right number(2) but i would only display the number of this specific ticket with value "En attente"

Answer 1

If I had to implement such a thing, I would do it somewhere in the PHP controller, something like this:
// In the controller:
$ticketsEnAttente = array_filter($tickets,
function($ticket) {
return $ticket['statut'] === 'En attente';
}
);
return $this->render('my_template.html.twig', [
'tickets_en_attente' => $ticketsEnAttente,
]);
Then it is trivial to show the count and the different tickets in Twig, something like:
<div>
{{ tickets_en_attente | length }} tickets en attente:
</div>
{% for ticket in tickets_en_attente %}
{{ loop.index }}
<div class="d-flex justify-content-start">
<a href="{{ path('ticket', {id:ticket.id}) }}" class="list-group-item list-group-item-action active">
<i class="fas fa-ticket-alt"></i>
{{ ticket.getNomProduit }}
</div>
</a> {# NOTE: there is an html error in your code, </div> and </a> are inverted #}
{% endfor %}
The only difference here is that the loop index will not be the same as the original code you gave, because it takes only into account the filtered list.
In a general way, it is a good idea to put as few as possible complex computations in the twig templates. Controllers and services are a better place for it.
EDIT
To answer to your comment, if there are several statuses, you can create a variable which groups tickets by their status:
// In your controller:
// Mock data:
$tickets = [
[ 'id' => 1, 'statut' => 'Fermé' ],
[ 'id' => 2, 'statut' => 'En attente' ],
[ 'id' => 3, 'statut' => 'Ouvert' ],
[ 'id' => 4, 'statut' => 'En attente' ],
];
// Group tickets by status:
$ticketsByStatus = [];
foreach ($tickets as $ticket) {
$ticketsByStatus[$ticket['statut']][] = $ticket;
}
// This is equivalent to writing this by hand:
$ticketsByStatus = [
'Fermé' => [
[ 'id' => 1, 'statut' => 'Fermé' ],
],
'En attente' => [
[ 'id' => 2, 'statut' => 'En attente' ],
[ 'id' => 4, 'statut' => 'En attente' ],
],
'Ouvert' => [
[ 'id' => 3, 'statut' => 'Ouvert' ],
],
];
return $this->render('default/index.html.twig', [
'tickets_by_status' => $ticketsByStatus,
]);
Then you can iterate over each status in the template (or access them manually if you prefer), something like this:
{% for status in tickets_by_status|keys %}
<h4>{{ status }}:</h4>
<ul>
{% for ticket in tickets_by_status[status] %}
<li>
{{ ticket.id }}
{# {{ ticket.getNomProduit }} #}
</li>
{% endfor %}
</ul>
{% endfor %}
Up to you to make this fit to your own needs.

Answer 2

Try this:
<div class="list-group">
{% set count = 0 %}
{% for ticket in tickets %}
{% if ticket.statut == 'En attente' %}
{{ loop.index }}
{{ ticket.statut }}
<div class="d-flex justify-content-start"><i class="fas fa-ticket-alt"></i> {{ ticket.getNomProduit }}</div>
{% set count = count + 1 %}
{% endif %}
{% endfor %}
{{ count }} Total File En attente
</div>
