我尝试上传4个或更少的图片,ajax验证不会返回任何错误,但在提交时我得到以下内容:
"错误":{ " imageFiles":[ "请上传文件。" ] }
ATTR:
/**
* @var UploadedFile[]
*/
public $imageFiles;
规则:
return [
[['imageFiles'], 'required', 'on' => self::REPORT_STEP1],
[['imageFiles'], 'file', 'skipOnEmpty' => false, 'maxFiles' => 4],
];
BeforeSave:
public function beforeSave($insert)
{
$files_urls = [];
$this->imageFiles = UploadedFile::getInstances($this, 'imageFiles');
foreach ($this->imageFiles as $file) {
$path = Url::to(['/uploads/reports/'], true) . Yii::$app->security->generateRandomString() . '.' . $file->extension;
$file->saveAs($path);
$files_urls[] = $file->name;
}
$this->img_url = json_encode($files_urls);
return parent::beforeSave($insert); // TODO: Change the autogenerated stub
}
形式:
<?php $form = ActiveForm::begin([
'enableAjaxValidation' => true,
'options' => [
'enctype' => 'multipart/form-data'
]
]) ?>
<?= $form->field($model, 'imageFiles[]')->fileInput(['multiple' => true, 'accept' => 'image/*']) ?>
<div class="form-group">
<?= Html::submitButton('Siguiente', ['class' => 'btn btn-standard']) ?>
</div>
<?php ActiveForm::end() ?>
