PHP實例本人搜索了很多關于yii2利用自帶UploadedFile實現上傳圖片介紹,下面我來記錄一下.
PHP實例創建一個 models/UploadForm.php:
PHP實例
namespace app\models;
use yii\base\Model;
use yii\web\UploadedFile;
/**
* UploadForm is the model behind the upload form.
*/
class UploadForm extends Model
{
/**
* @var UploadedFile file attribute
*/
public $file;
/**
* @return array the validation rules.
*/
public function rules()
{
return [
[['file'], ‘file'],
];
}
}
PHP實例視圖文件
PHP實例
<?php
use yii\widgets\ActiveForm;
?>
<?php $form = ActiveForm::begin([‘options' => ['enctype' => 'multipart/form-data']]) ?>
<?= $form->field($model, ‘file')->fileInput() ?>
<button>Submit</button>
<?php ActiveForm::end() ?>
PHP實例控制器
PHP實例
use app\models\UploadForm;
use yii\web\UploadedFile;
public function actionUpload()
{
$model = new UploadForm();
if (Yii::$app->request->isPost) {
$model->file = UploadedFile::getInstance($model, ‘file');
if ($model->file && $model->validate()) {
$model->file->saveAs(‘uploads/' . $model->file->baseName . ‘.' . $model->file->extension);
}
}
return $this->render(‘upload', ['model' => $model]);
}
