Symfony Increment value in Database - database

Question

I'm working on a website where people can download wallpapers.
I have a table 'Images' with a 'Download' column.
I would like to increment the value on this field for each time people click on the 'download button'
I'm usingg Symphony 6 with EasyAdmin-bundle & Twig
Can someone help me to make a query to increment this value ?
Thank you
enter image description here
<?php
namespace App\Entity;
use App\Repository\ImagesRepository;
use Doctrine\ORM\Mapping as ORM;
#[ORM\Entity(repositoryClass: ImagesRepository::class)]
class Images
{
#[ORM\Id]
#[ORM\GeneratedValue]
#[ORM\Column]
private ?int $id = null;
#[ORM\Column(length: 255)]
private ?string $name = null;
#[ORM\Column(length: 255)]
private ?string $image = null;
#[ORM\Column(nullable: true)]
private ?int $downloads = null;
#[ORM\ManyToOne(inversedBy: 'images')]
private ?Wallpapers $wallpaper = null;
#[ORM\ManyToOne(inversedBy: 'device')]
private ?Devices $devices = null;
public function getId(): ?int
{
return $this->id;
}
public function getName(): ?string
{
return $this->name;
}
public function setName(string $name): self
{
$this->name = $name;
return $this;
}
public function getImage(): ?string
{
return $this->image;
}
public function setImage(string $image): self
{
$this->image = $image;
return $this;
}
public function getDownloads(): ?int
{
return $this->downloads;
}
public function setDownloads(?int $downloads): self
{
$this->downloads = $downloads;
return $this;
}
public function getWallpaper(): ?Wallpapers
{
return $this->wallpaper;
}
public function setWallpaper(?Wallpapers $wallpaper): self
{
$this->wallpaper = $wallpaper;
return $this;
}
public function getDevices(): ?Devices
{
return $this->devices;
}
public function setDevices(?Devices $devices): self
{
$this->devices = $devices;
return $this;
}
public function __toString(): string
{
return $this->image;
}
}
<div class="row">
{% for item in wallpapers.getImages() %}
<div class="col">
<img src="/uploads/wps/{{ item.image }}" class="card"/>
<button>Download</button>
</div>
{% endfor %}
</div>
I tried many example but as it's my first experience with Symphony is a bit complicated to understand all the concept of Query Builder

You must create a new controller with route like this:
#[Route('/downloads/{entity}', name:'downloads')
public function downloads(
Entity $entity,
EntityManagerInterface $em
){
$entity->setDownload($entity->getDownload() + 1);
$em->persist($entity);
$em->flush();
return $this->file($entity->getImage(), 'name_file.ext');
}
in your twig file you can redirect to this func with entity id param.
Function is an example you must use your entity class and get file content to download something.
