Yii 未验证文件类型

我正在尝试在将文件类型保存到数据库之前验证它。这是我的规矩

array('picture', 'file', 'types'=>'jpg, gif, png, jpeg', 'allowEmpty'=>true, 'maxSize'=>1024*1024/*1mb*/, 'tooLarge'=>Yii::t('default', 'File is too large'), 'on'=>'create'),

我正在尝试上载多个图像

foreach($_FILES["picture"]["name"] as $key=>$value)
{
    $images->picture='file';
    $images->IDbuyitnow=1;
    if($images->validate())
        echo $value." ";
    else
        echo "doesnt work";
}

HTML代码

<?php echo CHtml::fileField('picture[]','',array('class'=>'form-control' ,'multiple'=>true, 'accept'=>'image/*')); ?>

---

我知道我应该使用CMultiUpload，但我想这样做。但即使$images->picture=file或25.docx，它也总是验证它。var_dump$images->validate返回true

[SOLVED]有史以来最奇怪的事情，属性不应该称为picture，而应该称为image

模型

<?php echo CHtml::fileField('image_file[]','',array('class'=>'form-control' ,'multiple'=>true, 'accept'=>'image/*')); ?>

$images=new BuyItNowImage;
$file=CUploadedFile::getInstancesByName('image_file');
foreach($fileas $key=>$value)
{
    $images->image_file=$value;
    $images->IDbuyitnow=1;

    if($images->validate())
        echo "ok";
    else
        echo "not ok";

}

array('image_file', 'file', 'types'=>'jpg, gif, png, jpeg', 'allowEmpty'=>true, 'maxSize'=>1024*1024/*1mb*/, 'tooLarge'=>Yii::t('default', 'File is too large')),
