php – JMS Serialize @VirtualProperty doesn't work

Posted by: admin July 12, 2020 Leave a comment


I’m trying to add a method to serialize, but JMS Serialize does not show the field.

use JMS\Serializer\Annotation\Groups;
use JMS\Serializer\Annotation\VirtualProperty;
use JMS\Serializer\Annotation\SerializedName;

class Ads
     * @VirtualProperty
     * @Type("string")
     * @SerializedName("Foo")
     * @Groups({"manage"})
    public function foo(){
        $foo = 'foo';
        return $foo;

And then:

use JMS\Serializer\SerializationContext;
use JMS\Serializer\SerializerBuilder;


$context = new SerializationContext();

$serializer = JMS\Serializer\SerializerBuilder::create()->build();
$jsonContent = $serializer->serialize($ad, 'json', $context);

I have not seen any examples of how to use VirtualProperty.

Is the syntax correct? What is wrong?

Thank you.

I’ve noticed the problem. There was created before the object “$ ad”. My fault. Virtual property functioning properly.
