Laravel全球突变体 [英] Global Mutator for Laravel

问题描述

我有许多不同的位置来插入和更新数据库，并且我希望能够 trim()用户输入的内容在插入数据库之前.我知道在模型中我可以执行以下操作，但是我不想在每个领域都执行此操作.有没有一种方法可以设置适用于所有字段的通用设置器?

I have many different locations ways of inserting and updating my database and I would like to be able to trim() the users input before inserting into the database. I know in the model I can do something like below, but I do not want to do this for every field. Is there a way to set a generic setter that works on all fields?

示例:

public function setSomFieldAttribute($value) {
     return $this->attributes['some_field'] = trim($value);
}

推荐答案

您可能将能够覆盖这些方法:

You probably will be able to override those methods:

<?php

class Post extends Eloquent {

    protected function getAttributeValue($key)
    {
        $value = parent::getAttributeValue($key);

        return is_string($value) ? trim($value) : $value;
    }

    public function setAttribute($key, $value)
    {
       parent::setAttribute($key, $value);

        if (is_string($value))
        {
            $this->attributes[$key] = trim($value);
        }
    }
}

而且您永远都不会再获得未修剪的值.

And you should never get an untrimmed value again.

在这里对此进行了测试，但我没有空格:

Tested this here and I got no spaces:

Route::any('test', ['as' => 'test', function()
{
    $d = Post::find(2);

    $d->title_en = "  Markdown Example  ";

    dd($d);
}]);
