如何在 2amigos/yii2-taggable-behavior 中设置默认值

Question

我想为我的更新页面设置可标记的默认值，但我做不到！

这是我在_form.php 中的代码。

https://github.com/2amigos/yii2-taggable-behavior

 <?=
    $form->field($model, 'tags')->widget(SelectizeTextInput::className(), [
        // calls an action that returns a JSON object with matched
        // tags

        'loadUrl' => ['tags/list'],
        'options' => ['class' => 'form-control'],
        'clientOptions' => [
            'plugins' => ['remove_button'],
            'valueField' => 'name',
            'labelField' => 'name',
            'searchField' => ['name'],
            'create' => true,
        ],
    ])->hint('Use commas to separate tags')
    ?>

这是我的模型：

class Post extends \yii\db\ActiveRecord
{

    public $category;
    public $prime;
    public $metaNames;
    public $metaDec;
    public $tags;

    /**
     * @inheritdoc
     */
    public static function tableName()
    {
        return 'post';
    }

    /**
     * @inheritdoc
     */
    public function rules()
    {
        return [
                [['menu', 'prime', 'slideshow', 'special', 'visit', 'deleted', 'active'], 'integer'],
                [['name', 'summary', 'text', 'sutitr', 'reference', 'slug', 'menu', 'slideshow', 'special', 'visit', 'created', 'modified', 'deleted', 'active'], 'required'],
                [['summary', 'tagDec', 'metaDec', 'tags', 'text', 'sutitr'], 'string'],
                [['created', 'modified'], 'safe'],
                ['category', 'each', 'rule' => ['integer']],
                [['tagNames'], 'safe'],
                [['headline'], 'string', 'max' => 255],
                [['name', 'reference'], 'string', 'max' => 100],
                [['slug'], 'string', 'max' => 200],
                [['user_id'], 'exist', 'skipOnError' => true, 'targetClass' => User::className(), 'targetAttribute' => ['user_id' => 'id']],
        ];
    }

我想在更新页面设置默认标签。

在SelectizeTextInput 中真正使用属性value 设置选定值：

SelectizeTextInput::widget([
    'name' => 'tags',
    'value' => 'love, this, game',
    'clientOptions' => [
        // ...
    ],
]);

您需要像example 那样设置与表格帖子的关系，以获取您之前设置的值。

public function getTags(){
    return $this->hasMany(Tag::className(), ['id' => 'tag_id'])->viaTable('post_tag_assn', ['post_id' => 'id']);
}
