如何限制 redactor limiter 插件的最大字符数？

Question

我有这段代码

<div class="col-xs-6">
        <?php echo $form->field($model, 'deskripsi_produk')->widget(Redactor::className(),['clientOptions'=>['autoresize'=>'true', 'limiter' => 20, 'plugins' => ['limiter'], 'buttons'=> ['html', 'formatting', 'bold', 'italic','underline','lists','horizontalrule'],]]);?>
        </div>

它可以限制 20 个字符，但我如何将文本区域限制为模型上定义的最大字符串而不是限制特定数字？

这是我的模型

class TbProduk extends \yii\db\ActiveRecord
{
    /**
     * @inheritdoc
     */
    public  $image;
    public static function tableName()
    {
        return 'tb_produk';
    }

public function rules()
{
    return [
        ...
        [['deskripsi_produk'], 'string', 'max' => 2000],
        [['deskripsi_produk'], 'checkDesc'],
        ...
    ];
}
}

试图通过 rules 获取值是个糟糕的主意。相反，您应该在 TbProduk 中创建一个常量来保存长度：

class TbProduk extends \yii\db\ActiveRecord
{
    const DESKRIPSI_PRODUK_LENGTH = 2000;
    ...
    public function rules()
    {
        return [
            ...
            [['deskripsi_produk'], 'string', 'max' => static::DESKRIPSI_PRODUK_LENGTH],
            ...
        ];
    }
}

在您看来：

<div class="col-xs-6">
    <?php echo $form->field($model, 'deskripsi_produk')->widget(Redactor::className(),['clientOptions'=>['autoresize'=>'true', 'limiter' => TbProduk::DESKRIPSI_PRODUK_LENGTH, 'plugins' => ['limiter'], 'buttons'=> ['html', 'formatting', 'bold', 'italic','underline','lists','horizontalrule'],]]);?>
</div>
