Yii2 如何限制redactor限制器插件的最大字符数？

我有这个代码在我看来

<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>

试图通过

规则

获取值是一个糟糕的想法。相反，您应该在

TbProduk

中创建一个常量，用于保存长度：

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

在你看来：

<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>

模型中定义的最大长度在哪里？@topher问题已更新

<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>
