這篇文章主要介紹了yii2.0框架實現(xiàn)上傳excel文件后導入到數(shù)據(jù)庫的方法,結(jié)合實例形式詳細分析了yii2.0上傳excel文件后導入到數(shù)據(jù)庫的相關(guān)模型、視圖、控制器實現(xiàn)技巧,需要的朋友可以參考下

本文實例講述了yii2.0框架實現(xiàn)上傳excel文件后導入到數(shù)據(jù)庫的方法。分享給大家供大家參考，具體如下：

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'=> '上傳文件'
    ];
  }

  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 '驗證失敗';
    }
  }

}

Views視圖

<?php

use 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>上傳</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
{
  /**
   * 導入
   * @author zcy
   * @date 2019/8/16
   */
  public function actionImport()
  {
    $model = new uploadForm();

    if (Yii::$app->request->isPost) {
      $model->file = UploadedFile::getInstance($model,'file');
//      if ($model->upload()) {
//        print <<<EOT
// <script>alert('上傳成功')</script>
//EOT;
//      } else {
//        print <<<EOT
// <script>alert('上傳失敗')</script>
//EOT;
//      }
      if (!$model->upload()) {
        print <<<EOT
 <script>alert('上傳失敗')</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);//文件名自動判斷類型
          $excelReader = \PHPExcel_IOFactory::createReader($fileType);

          $phpexcel = $excelReader->load($filename)->getSheet(0);//載入文件并獲取第一個sheet
          $total_line = $phpexcel->getHighestRow();//總行數(shù)
          $total_column = $phpexcel->getHighestColumn();//總列數(shù)

          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('導入成功');window.history.back();</script>";
          } else {
            echo "<script>alert('操作失敗');window.history.back();</script>";
          }
        }
      }
    } else {
      return $this->render('import',['model' => $model]);
    }
  }
}
