any help :( ?

Hi!

May I ask why you are writing in English on a French forum?

Could you please use the [ CODE ][ /CODE ] tag around your code to make it readable? And formatting your code may also help you understand your mistakes... Have a look at PSR2 coding standard, and tools to help you (php-cs-fixer from sensiolabs and squizlabs/php_codesniffer are what you should look for).

Back to your problem:

Code:

function listAction()
{
    $marques = array('BMW','Renault','Fiat');
    //list des voitures
    $voiture = array(
        array('Id' => 'C2345', 'serie' => '176', 'dateMiseCirculation' => '01/01/2014', 'Marque' => 'BMW'),
        array('Id' => 'A2345', 'serie' => '186', 'dateMiseCirculation' => '13/01/2015', 'marque' => 'Renault'),
        array('Id' => 'W0308', 'serie' => '196', 'dateMiseCirculation' => '02/11/2012', 'marque' => 'Fiat')
    );
    return $this->render(
        'MyAppEspritParcBundle:Voiture:list.html.twig',
        array('marques' => $marques, 'voiture' => $voiture)
    );
}

Here it is:

The first car as an index Marque, the others marque, so it's different indexes
$voiture should be $voitures (plural) as it is an array of objects

Therefore:

Code:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
 
function listAction()
{
    $marques = array('BMW', 'Renault', 'Fiat');
    //list des voitures
    $voitures = array(
        array('id' => 'C2345', 'serie' => '176', 'dateMiseCirculation' => '01/01/2014', 'marque' => 'BMW'),
        array('id' => 'A2345', 'serie' => '186', 'dateMiseCirculation' => '13/01/2015', 'marque' => 'Renault'),
        array('id' => 'W0308', 'serie' => '196', 'dateMiseCirculation' => '02/11/2012', 'marque' => 'Fiat')
    );
    return $this->render(
        'MyAppEspritParcBundle:Voiture:list.html.twig',
        array('marques' => $marques, 'voitures' => $voitures)
    );
}

Then you have to change the view accordingly:

Code:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15

    <h2>Liste des voitures</h2>
    <table border="1">
        <tr>
            <td>Id</td>
            <td>Série</td>
            <td>Date de Mise Circulation</td>
            <td>Marque</td>
        </tr>
        {%for voiture in voitures %}
        <tr>
            <td>{{ voiture.id }}</td>
            <td>{{ voiture.serie }}</td>
            <td>{{ voiture.dateMiseCirculation }}</td>
            <td>{{ voiture.marque }}</td>
        </tr>
        {% endfor %}
    </table>

That is why it is so important to be consistent (variable names in lowerCamelCase, plurals for your collections).
You should also use classes instead of arrays, so you can ensure id, serie, dateMiseCirculation and marque exist for each entity (here entity = subarray).
