如何在Laravel中使用Getter Setter方法？如何使用雄辩模型添加字段？

这是我的User.php模型

<?php

namespace App;

use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
{
    use Notifiable;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'firstname','lastname', 'email','image', 'password',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];
}

我只想使用getter setter方法和雄辩的模型获得url的完整路径

<?php

namespace App;

use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
{
    use Notifiable;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'firstname','lastname', 'email','image', 'password',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];
}

像这样

Array
(
    [0] => Array
        (
            [id] => 1
            [firstname] => admin
            [lastname] => Gomez
            [email] => admin@admin.com

            [image] => public/images/admin.png

            [created_at] => 2019-11-10 04:30:01
            [updated_at] => 2019-11-10 14:03:38
        )

)

我还想添加另一个字段，如fullname（如[fullname]=>AdminGomez）

我也想要这个

Array
(
    [0] => Array
        (
            [id] => 1
            [firstname] => admin
            [lastname] => Gomez
            [email] => admin@admin.com
            [image] => admin.png
            [created_at] => 2019-11-10 04:30:01
            [updated_at] => 2019-11-10 14:03:38

            [fullname] => admin gomez
        )

)

谢谢

请在您的模型中定义这两种方法：

protected $append = ['full_name'];

/**
 * Get the user's full name.
 *
 * @return string
 */
public function getFullNameAttribute()
{
    return "{$this->first_name} {$this->last_name}";
}

/**
 * Get full image path
 *
 * @return string
 */
public function getImageAttribute()
{
    if ($this->image) {
        return public_path($this->image);
    }

    return '';
}

---

用户模型上图像的getter如下所示：

public function getImageAttribute()
{
    return public_path('images') . $this->image;
}

全名应该是文档中的内容，减去您案例中的下划线：

public function getFullNameAttribute()
{
    return "{$this->first_name} {$this->last_name}";
}

如果你想弄清楚它是如何工作的或者为什么工作的，那是因为Laravel使用了PHP的神奇方法。在这种情况下uuu得到。因此，模型基本上会查找任何get，如果存在，则使用“getFieldNameAttribute”方法
