Select from table where row equal to option symfony2 - php

Question

I have a table generated by a crud in symfony2. The entity is called "Voorraad"(=Stock) and is a table of 3 items: "aantal"(=number), "locatie_id"(location_id) and "product_id". Both the location id and product id are associations with another enitty (locatie entity and product entity). I try to order my stock by location but I cant get it right in symfony. I would like to have a option to select a location (id 1, id 2, id 3) and If a have selected a option it outputs the data of that location.
In mysql its the following query
SELECT * FROM `voorraad` WHERE `locatie_id` = 1
How can I achieve something like this in Symfony2/doctrine/twig?
My code:
View
{% extends '::base.html.twig' %}
{% block body -%}
<h1 class="hoofdtitel">Voorraad lijst</h1>
<table class="records_list">
<thead>
<tr>
<!-- <th>Id</th> -->
<th>Product</th>
<th>Type</th>
<th>Fabriek</th>
<th>Aantal</th>
<th>Inkoopprijs</th>
<th>Verkoopprijs
<th>Locatie</th>
<th>Actions</th>
</tr>
</thead>
<tbody>
{% for entity in entities %}
<tr>
<!-- <td>{{ entity.id }}</td> -->
<td>{{ entity.getProduct().getNaam() }}</td>
<td>{{ entity.getProduct().getType() }}</td>
<td>{{ entity.getProduct().getFabric().getFabrieknaam() }}</td>
<td>{{ entity.aantal }}</td>
<td>{{ entity.getProduct().getInkoopprijs() }}</td>
<td>{{ entity.getProduct().getVerkoopprijs() }}</td>
<td>{{ entity.getLocatie().getLocatienaam() }}</td>
<td>
Voorraad aanpassen
</td>
</tr>
{% if
entity.aantal == 1 %}
<div class="alert alert-info" role="alert"> <p>Let op, voorraad van {{ entity.getProduct().getNaam() }} is 1 of minder </p></div>
{% endif %}
{% if
entity.aantal <= 0 %}
<div class="alert alert-danger" role="alert"> <p>Let op, voorraad van {{ entity.getProduct().getNaam() }} is op </p></div>
{% endif %}
{% endfor %}
</tbody>
</table>
<br>
<a href="{{ path('voorraad_new') }}">
Nieuwe voorraad toevoegen
</a>
{% endblock %}

Answer 1

You can use doctrine's findBy method :
$entities = $em->getRepository('ToolsForEverVoorraadBundle:Voorraad')
->findBy(['locatie'=>$locatieId]);

Answer 2

You can create a method in your controller for this goal.An approximate code is as follows (but it all depends on your mapping info and attributes names).
public function getVoorraadByLocatieId($locatieId)
{
$em = $this->getDoctrine()->getManager();
$query = $em->createQuery(
'SELECT v
FROM ToolsForEverVoorraadBundle:Voorraad v
WHERE v.locatie = :l_id'
)->setParameter('l_id', $locatieId);
$result = $query->getResult();
return $result;
}
And in your action, do:
$this->getVoorraadByLocatieId($locatieId);
There are different ways of achieving the same result, like creating a service and calling it from inside controller (fat services with thin controllers is a god practice), or creating a custom Repository Class, but the idea is the same (the use of entity manager and doctrine fetching ). The advantage of latter ways is code organization/readability.
