接口致命错误

Question

So this is my code on my newly created page inside the Entity folder...

use Doctrine\ORM\Mapping as ORM;
use Application\Entity\Categories;
use PerfectWeb\Core\Interfaces\Routable;
use Application\Mapper\Injector;
use PerfectWeb\Core\Traits;
use PerfectWeb\Core\View\Helper\Object;
use PerfectWeb\Core\Utils\Slug;

/**
 * @ORM\Entity
 */
class VodCategory extends Categories implements 
Entity\Interfaces\Categories, Routable
{

    function getRoute($type = Object::ROUTE_TYPE_VIEW)
    {
        return 'category/categories';
    }

    function getRouteParams()
    {
        return
            [
            Injector::CATEGORY => $this->getID(),
            'slug' => Slug::getSlug($this->getSlug()),
            ];
    }
}

And this is my category.php file:

<?php

namespace Application\Entity;

use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Mapping as ORM;
use PerfectWeb\Core\Traits;

/**
 * Categories
 * @ORM\Table(name="categories")
 * @ORM\Entity
 */
class Categories
{

    use Traits\Entity;
    use Traits\User;
    use Traits\Name;

    /**
     * @var integer
     *
     * @ORM\Column(name="id", type="integer", nullable=false)
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

    /**
     * @var string
     *
     * @ORM\Column(name="name", type="string", nullable=false, unique=false)
     */
    protected $name;

    /**
     * @ORM\ManyToOne(targetEntity="Categories", cascade={"persist"})
     * @ORM\JoinColumn(name="parent_id", referencedColumnName="id", nullable=true, onDelete="SET NULL")
     * @var integer
     */
    protected $parent = null;

    /**
     * @var \Application\Entity\User
     *
     * @ORM\ManyToOne(targetEntity="User", inversedBy="categories")
     * @ORM\JoinColumn(name="user", referencedColumnName="id", onDelete="CASCADE")
     */
    protected $user;

    /**
     *
     * @ORM\OneToMany(targetEntity="Videos\Entity\Video", mappedBy="category", fetch="EXTRA_LAZY"))
     *
     */
    protected $videos;

    /**
     * @var string
     *
     * @ORM\Column(name="entity", type="string", nullable=true, unique=false)
     */
    protected $entity;

    /**
     *
     * construct function for array collection
     */
    public function __construct()
    {
        $this->videos = new ArrayCollection();
    }

    /**
     * @return mixed
     */
    public function getVideos()
    {
        return $this->videos;
    }

    /**
     * @param mixed $videos
     */
    public function setVideos($videos)
    {
        $this->videos = $videos;
    }

    /**
     * @return int
     */
    public function getId()
    {
        return $this->id;
    }

    /**
     * Get parent
     *
     * @return integer
     */
    public function getParent()
    {
        return $this->parent;
    }

    /**
     * Set parent
     *
     * @param integer $parent
     * @return Categories
     */
    public function setParent($parent)
    {
        $this->parent = $parent;
        return $this;
    }

    public function __toString()
    {
        return $this->getName();
    }
}

the first bit of code gives me an error:

Fatal Error Interface 'Categories\Entity\Interfaces\Categories' not found in /var/www/html/camclients/module/Videos/src/Videos/Entity/VodCategory.php

What am I doing wrong?

Answer 1

You implement the interface Entity\Interfaces\Categories inside your category class but this interface cannot be found. You should have an interface in that namespace (and folder) or you should point to the correct location (the folder/namespace where your interface is located).

If your interface exists then it is probably a namespace issue like @doydoy44 suggested in the comment. Then make sure that the namespace declaration and file location of your interface are correct.
