Import CSV Data through a Controller

You can have more customized logic and interface feedback through a custom controller. Let's create a simple upload form (which is used for MyDataObject instances). You can access it through http://yoursite.com/MyController/?flush=all.

:::php
<?php

class MyController extends Controller {

	private static $allowed_actions = array(
		'Form'
	);

	protected $template = "BlankPage";

	public function Link($action = null) {
		return Controller::join_links('MyController', $action);
	}

	public function Form() {
		$form = new Form(
			$this,
			'Form',
			new FieldList(
				new FileField('CsvFile', false)
			),
			new FieldList(
				new FormAction('doUpload', 'Upload')
			),
			new RequiredFields()
		);
		return $form;
	}

	public function doUpload($data, $form) {
		$loader = new CsvBulkLoader('MyDataObject');
		$results = $loader->load($_FILES['CsvFile']['tmp_name']);
		$messages = array();

		if($results->CreatedCount()) {
			$messages[] = sprintf('Imported %d items', $results->CreatedCount());
		}

		if($results->UpdatedCount()) {
			$messages[] = sprintf('Updated %d items', $results->UpdatedCount());
		}

		if($results->DeletedCount()) {
			$messages[] = sprintf('Deleted %d items', $results->DeletedCount());
		}

		if(!$messages) {
			$messages[] = 'No changes';
		}

		$form->sessionMessage(implode(', ', $messages), 'good');

		return $this->redirectBack();
	}
}

This interface is not secured, consider using [api:Permission::check()] to limit the controller to users with certain access rights.
