Drupal8下面,第一次写批处理,写好以后,运行,报了这样的错误信息:

ErrorUsing $this when not in object context 在函数 Drupal\qipu\Form\QipuConvertForm::processConvert()(文件 /../modules/qipu/src/Form/QipuConvertForm.php 87 行)#0 /../core/includes/batch.inc(252): Drupal\qipu\Form\QipuConvertForm::processConvert(Array) #1 /../core/includes/batch.inc(95): _batch_process() #2 /../core/includes/batch.inc(77): _batch_do() #3 /../core/modules/system/src/Controller/BatchController.php(55): _batch_page(Object(Symfony\Component\HttpFoundation\Request)) #4 [internal function]: Drupal\system\Controller\BatchController->batchPage(Object(Symfony\Component\HttpFoundation\Request)) #5

   通过搜索,发现,原来的代码写的有问题:

    $batch = array(

      'operations' => array(

        array(array('\Drupal\qipu\Form\QipuConvertForm', 'processConvert'), array())

      ),

      'finished' => array('\Drupal\qipu\Form\QipuConvertForm', 'finishConvert'),

      'title' => t('转换中'),

      'error_message' => t('转换中遇到错误.'),

    );

batch_set($batch);

 

批处理是在\Drupal\qipu\Form\QipuConvertForm这个类中调用的,这里正确的写法是:

    $batch = array(

      'operations' => array(

        array(array($this, 'processConvert'), array())

      ),

  //'\Drupal\qipu\Form\QipuConvertForm'

      'finished' => array($this, 'finishConvert'),

      'title' => t('转换中'),

 

      'error_message' => t('转换中遇到错误.'),

 

    );

    batch_set($batch);


需要将当前类名的全称,改为 $this即可。
