yii2-importexport

Extension for the Yii2 framework for importing and exporting data with PHPExcel.

php composer.phar require --prefer-dist boundstate/yii2-importexport "*"

or add

"boundstate/yii2-importexport": "*"

to the require section of your composer.json file.

Usage

Implement the ImportInterface and/or ExportInterface:

class Contact extends \yii\db\ActiveRecord implements ImportInterface, ExportInterface
{
    ...

    public function import($reader, $row, $data)
    {
        if ($row == 0) {
            if ($data != ['First Name', 'Last Name', 'Email']) {
                $reader->addError($row, 'Invalid headers.');
                return false;
            }
            // Skip header row
            return true;
        }

        // Create contact from data
        $contact = new Contact;
        ...
    }

    public function export() {
        return self::find()->asArray()->all();
    }
}

Now you can import data using ExcelReader and your class as the destination:

public function actionImport()
{
    $form = new ImportForm();
    $form->file = UploadedFile::getInstanceByName('file');

    if ($form->validate()) {
        Contact::deleteAll();
        $reader = new ExcelReader(['destination' => Contact::className()]);
        $reader->import($form->file->tempName);
        if ($reader->getErrors()) {
            // Handle errors
            ...
        }
    }
    return $form;
}

Or export data using ExcelWriter and your class as the source:

public function actionExport()
{
    $writer = new ExcelWriter(['source' => Contact::className()]);
    $filename = $writer->write('Excel2007');
    Yii::$app->response->sendFile($filename, 'contacts.xlsx')->send();
}
