需要slug字段值作为JDoe（对于John Doe）的学说

Question

如何将slug字段设置为JDoe（名字的J-First字符，Doe - 完整的姓氏）;

/**
 * @var string
 *
 * @Gedmo\Slug(fields={"firstName", "lastName"}, separator="??")
 * @ORM\Column(name="slug", type="string", length=20, unique=true)
 */

谢谢！

Answer 1

方法1

我没有尝试过以下内容，但它可能是您正在寻找的代码段。试一试，让我知道它是否有效：

class SomeEntity
{
    /**
     * @var string
     *
     * @Gedmo\Slug(fields={"getFirstNameSlugged", "lastName"}, separator="??")
     * @ORM\Column(name="slug", type="string", length=20, unique=true)
     */
    private $slug;

    private function getFirstNameFirstLetter()
    {
        return substr ($this->firstName, 0 , 1);
    }

    private function getFirstNameSlugged()
    {
        return ucfirst (getFirstNameFirstLetter());
    }

}

方法2

实体中的

使用setSlug()方法：

class SomeEntity
{
    const SEPERATOR = '??';

    /**
     * @var string
     *
     * @Gedmo\Slug(fields={"firstName", "lastName"}, separator="??")
     * @ORM\Column(name="slug", type="string", length=20, unique=true)
     */
    private $slug;

    private function getFirstNameFirstLetter()
    {
        return substr ($this->firstName, 0 , 1);
    }

    private function getFirstNameSlugged()
    {
        return ucfirst (getFirstNameFirstLetter());
    }

    private function getLastNameSlugged()
    {
        return ucfirst ($this->getLastName());
    }

    public function setSlug()
    {
        $this->slug = $this->getFirstNameSlugged() . self::SEPERATOR . $this->getLastNameSlugged();

        return $this->slug;
    }
}

并在控制器：

中

$entity = new SomeEntity;
$entity->setSlug();

$em->persist($entity);
$em->flush();

方法3

在实体中，创建一个方法并将其设置在控制器中：

class SomeEntity
{
    /**
     * @var string
     *
     * @Gedmo\Slug(fields={"firstName", "lastName"}, separator="??")
     * @ORM\Column(name="slug", type="string", length=20, unique=true)
     */
    private $slug;

    private function getFirstNameFirstLetter()
    {
        return substr ($this->firstName, 0 , 1);
    }

    private function getFirstNameSlugged()
    {
        return ucfirst (getFirstNameFirstLetter());
    }

    private function getLastNameSlugged()
    {
        return ucfirst ($this->getLastName());
    }

    public generateSlug()
    {
        $slug = $this->getFirstNameSlugged() . self::SEPERATOR . $this->getLastNameSlugged();

        return $slug;
    } 
}

并在控制器：

中

$entity = new SomeEntity;

$callable = array('AppBundle\Entity\SomeEntity', 'generateSlug');
$sluggableListener = new \Gedmo\Sluggable\SluggableListener();
$sluggableListener->setTransliterator($callable);

$em->persist($entity);
$em->flush();
