    我的为什么会提示

    QQ截图20161028181545.png

    请帮我看一下,我贴上代码

    <?php

        public static function find()

            $cates = ArrayHelper::toArray($cates);
            return $cates;
        }
    
        public function getCatTree($cats,$bclassid= 0, $nu = 0)
        {
            $bx = '---|';
            $nu++;
            foreach ($cats as $cat) {
                $catid = $cat['parentid'];
                $catname = $cat['catename'];
                $catbcid = $cat['bclassid'];
                if ($catbcid == $bclassid) {
                    $this->tree[$catid] = str_repeat($bx,$nu).'~'.$catename.PHP_EOL;
                    $this->getCatTree($cats,$catid,$nu);

        }

            return $this->tree ;
        }
    }
    
    

    这是model的代码,视图中是这样的

    <?= $form = ActiveForm::begin() ?>
    		<?= $form->field($model,'cateid')->dropDownList($model->tree(),['prompt'=> '请选择']) ?>
    	<?= $form->field($model,'catename')->textInput(['maxlength' => true]) ?>
    	<div class="form-group">
    		<?= Html::submitButton($model->isNewRecord ? 'Create' : 'Update', ['class' => $model->isNewRecord ? 'btn btn-success' : 'btn btn-primary']) ?>
    	</div>
    	<?= ActiveForm::end() ?>

    先看看这个吧!
    需要有个父ID,即 bclassid = 0

    另外建议先打印出结果
