php - Problems encountered when using the reader (getAttribute) in laravel

Question

The scene is:

When displaying the tel field in a Users table in the foreground, the last 4 digits of the phone number are replaced with *.

The method I use is:

class User extends Model
{
    public function getTelAttribute () {
        return substr($this->attributes['tel'], 0, 7) . '****';
    }
}

If you write it like this, it will generally be fine.

However, when the user modifies personal information through the form, the phone number displayed in the input is

Example: 1391234**

What I want to solve is:

In the case of using the reader (getAttribute), how to
temporarily cancel the action to the reader (getAttribute) under certain conditions, so as to display the complete phone number?

Answer 1

1. Make two

ExportArray时隐藏一个，这样做有弊病，导出的JSON接口中，telare all**

protected $hidden = [
    'tel_original'
];

function getTelAttribute() {
    return substr($this->attributes['tel'], 0, 7) . '****');
}

function getTelOriginalAttribute() {
    return $this->attributes['tel'];
}

2. Runtime replacement

No changetel，但是在模板中显示时，用函数替换一下
这样对导出JSONhas no effect, it just needs to be replaced with a function every time it is displayed
