Question

我想将上传的文件（pdf）附加到普通的创建功能，但它确实不起作用。我有模型，控制器，表单修改，它说上传，模型验证，但仍然，在db中没有pdf。我将字段设置为blob。什么可能是错的？

模型：

use yii\web\UploadedFile;
class MyModel extends \yii\db\ActiveRecord {

public $file;
...

public function rules() {
    return [
        [['file'], 'file', 'skipOnEmpty' => true, 'extensions' => 'pdf'],
...

_form：

$form = ActiveForm::begin([
    'enableClientValidation' => false,
    'options' => ['enctype' => 'multipart/form-data'],
    ]
...
<?= $form->field($model, 'file')->fileInput() ?>

控制器：

use yii\web\UploadedFile;
public function actionCreate() {
    $model = new MyModel;

    try {
        if ($model->load($_POST)) {
            $model->file = UploadedFile::getInstance($model, 'file');

            if ($model->save()) {
...

这适用于文件上传

$model->file = UploadedFile::getInstance($model, 'file');//Get the uploaded file

$model->file->saveAs('uploads/' . $model->file->name);//Save uploaded file at your desired location

$user->image = $model->file->name;//image is my database field name,to only save the name of the uploaded file

我希望这能说清楚并解决你的问题
