I have in my patient space, a list of doctors with whom he has made an appointment.And next to each doctor, I want to add a button I like so that the patient can tell if he liked or not the consultation with the doctor.
And I would like to know the number of patients who have liked a given doctor. For this number to be displayed in the doctor's details.

Here is my controller where I have my list of doctors

Controller

 public function patientBookingListAction(Request $request)

{



    $em  = $this->getDoctrine()->getManager();



    $medecin = $em->getRepository("DoctixMedecinBundle:Medecin")->findOneBy(array(

        'user' => $this->getUser(),

    ));



    $patient = $em->getRepository("DoctixPatientBundle:Patient")->findOneBy(array(

        'user' => $this->getUser(),

    ));



    $bookings = $em->getRepository("DoctixFrontBundle:Booking")->findBy(array(

        "patient" => $patient

    ));



    $bookings = $this->get('knp_paginator')->paginate($bookings, $request->query->get('page', 1), 3);





    return $this->render('DoctixPatientBundle:Patient:bookings.html.twig', array(

        'bookings' => $bookings

    ));

}

I had already create my table favorite_doctor :

Entity favorite_doctor

  class MedecinFavoris

 {

/**

 * @var int

 *

 * @ORMColumn(name="id", type="integer")

 * @ORMId

 * @ORMGeneratedValue(strategy="AUTO")

 */

private $id;





/**

 * @ORMManyToOne(targetEntity="DoctixPatientBundleEntityPatient", inversedBy="medecin_favoris")

 * @ORMJoinColumn(name="patient_id", referencedColumnName="id")

 */

private $patient;



   /**

 * @ORMManyToOne(targetEntity="DoctixMedecinBundleEntityMedecin", inversedBy="medecin_favoris")

 * @ORMJoinColumn(name="medecin_id", referencedColumnName="id")

 */

private $medecin;







/**

 * Get id

 *

 * @return integer

 */

public function getId()

{

    return $this->id;

}



/**

 * Set patient

 *

 * @param DoctixPatientBundleEntityPatient $patient

 *

 * @return MedecinFavoris

 */

public function setPatient(DoctixPatientBundleEntityPatient $patient = null)

{

    $this->patient = $patient;



    return $this;

}



/**

 * Get patient

 *

 * @return DoctixPatientBundleEntityPatient

 */

public function getPatient()

{

    return $this->patient;

}



/**

 * Set medecin

 *

 * @param DoctixMedecinBundleEntityMedecin $medecin

 *

 * @return MedecinFavoris

 */

public function setMedecin(DoctixMedecinBundleEntityMedecin $medecin = null)

{

    $this->medecin = $medecin;



    return $this;

}



/**

 * Get medecin

 *

 * @return DoctixMedecinBundleEntityMedecin

 */

public function getMedecin()

{

    return $this->medecin;

}

 }

I would like that when I click on the button like that my data is saved in this table.

Twig

  {% for booking in bookings %}

        <div class="list_general" id="liste">

            <a href="#0" class="wish_bt"></a>

            <ul>

                <li>

                    <figure><img src="{{ vich_uploader_asset(booking.medecin.media, 'imageFile') }}"

                                                         alt="{{ booking.medecin.media.imagename }}"></figure>

                    <h4>Dr. {{ booking.medecin.user.prenom|capitalize }} {{ booking.medecin.user.nom|upper }} <i class="pending">Pending</i></h4>

                     <ul class="booking_details">

                        <li><strong>Date et heure</strong>{{ booking.dateHeureRdv|date('d/m/Y') }}</li>

                        <li><strong>Heure</strong>{{ booking.dateHeureRdv|date('H:i') }}</li>

                        <li><strong>Motif</strong>Consultation</li>

                        <li><strong>Téléphone</strong>{{ booking.medecin.user.numTel }}</li>

                        <li><strong>Email</strong>{{ booking.medecin.user.username }}</li>

                    </ul>

                    <ul class="buttons">

                        <li><a href="{{ path('patient_booking_deplacer', {'id': booking.id}) }}?medecin={{ booking.medecin.id }}" class="btn_1 gray approve"><i class="fa fa-fw fa-check-circle-o"></i> Déplacer Rdv</a></li>

                        <li><a href="{{ path('patient_booking_annuler', {'id': booking.id}) }}" class="btn_1 gray delete"><i class="fa fa-fw fa-times-circle-o"></i> Annuler</a></li>

                    </ul>

                </li>

                <div class="like">

                <a href="#" class="fa fa fa-thumbs-up">Like</a>

                </div>  

                </ul>



        </div>

    {% endfor %}    

Now i do not know exactly what to do when i click the like button. Knowing that when a patient like, the data must register in the database and the like button must also disappear to no longer allow him to vote two or more times.

Thanks a lot
