本文实例讲述了yii2.0框架实现上传excel文件后导入到数据库的方法。分享给大家供大家参考，具体如下：

Model模型

<?php/** * 描述... * @author zcy * @date 2019/8/13 */namespace app\models;use yii\base\Model;use yii\db\ActiveRecord;use yii\web\UploadedFile;class uploadForm extends ActiveRecord{ public $file; public function rules() { return [ [['file'],'file', 'skipOnEmpty' => false,'extensions' => 'xls,xlsx'], ]; } public function attributeLabels() { return [ 'file'=> '上传文件' ]; } public function upload() { $file = UploadedFile::getInstance($this, 'file'); if ($this->rules()) { $tmp_file = $file->baseName . '.' . $file->extension; $path = 'upload/' . 'Files/'; if (is_dir($path)) { $file->saveAs($path . $tmp_file); } else { mkdir($path, 0777, true); } $file->saveAs($path . $tmp_file); return true; } else { return '验证失败'; } }}

Views视图

<?phpuse yii\widgets\ActiveForm;$model = new app\models\uploadForm();$form = ActiveForm::begin([ 'id' => 'upload', 'options' => ['enctype' => 'multipart/form-data'],])?><?= $form->field($model,'file')->fileInput(['multiple'=>'multiple']) ?> <button>上传</button><?php ActiveForm::end() ?>

Controller控制器

<?php/** * 描述... * @author zcy * @date 2019/8/16 */namespace app\controllers;use app\models\uploadForm;use Yii;use yii\web\Controller;use yii\web\UploadedFile;class UploadController extends Controller{ /** * 导入 * @author zcy * @date 2019/8/16 */ public function actionImport() { $model = new uploadForm(); if (Yii::$app->request->isPost) { $model->file = UploadedFile::getInstance($model,'file');// if ($model->upload()) {// print <<<EOT// <script>alert('上传成功')</script>//EOT;// } else {// print <<<EOT// <script>alert('上传失败')</script>//EOT;// } if (!$model->upload()) { print <<<EOT <script>alert('上传失败')</script>EOT; } } $ok = 0; if ($model->load(Yii::$app->request->post())) { $file = UploadedFile::getInstance($model,'file'); if ($file) { $filename = 'upload/Files/' . $file->name; $file->saveAs($filename); if (in_array($file->extension,array('xls','xlsx'))) { $fileType = \PHPExcel_IOFactory::identify($filename);//文件名自动判断类型 $excelReader = \PHPExcel_IOFactory::createReader($fileType); $phpexcel = $excelReader->load($filename)->getSheet(0);//载入文件并获取第一个sheet $total_line = $phpexcel->getHighestRow();//总行数 $total_column = $phpexcel->getHighestColumn();//总列数 if (1 < $total_line) { for ($row = 2;$row <= $total_line;$row++) { $data = []; for ($column = 'A';$column <= $total_column;$column++) { $data[] = trim($phpexcel->getCell($column.$row)); } $info = Yii::$app->db->createCommand()->insert('{{%shop_info}}',['shop_name' => $data[0],'shop_type' => $data[1]])->execute(); if ($info) { $ok = 1; } } } if ($ok == 1) { echo "<script>alert('导入成功');window.history.back();</script>"; } else { echo "<script>alert('操作失败');window.history.back();</script>"; } } } } else { return $this->render('import',['model' => $model]); } }}
