Drupal 7 배치 페이지 예제

Question

처리를 위해 배치 페이지를 설정하려고하는데 예제가 필요합니다. 예제 모듈에있는 예제는 폼 내에 있으며 배치 요청을 처리 할 폼과 독립적으로 실행할 수있는 페이지가 필요합니다. 예를 들어

: 일괄 처리 기능은 $ 작업의 형태로 다른 함수를 호출 할

function mymodule_batch_2() { 
$operations[] = array('mymodule_onefunction','mymodule_anotherfunction') 
$batch = array(
    'operations' => $operations, 
    'finished' => 'mymodule_finished', 
    // We can define custom messages instead of the default ones. 
    'title' => t('Processing batch 2'), 
    'init_message' => t('Batch 2 is starting.'), 
    'progress_message' => t('Processed @current out of @total.'), 
    'error_message' => t('Batch 2 has encountered an error.'), 
); 
    batch_set($batch); 
    batch_process(''); 
} 

.

Answer 1

작업 할 ID를 배치 프로세스에 제공해야합니다. batch_process ('mybatch') 그렇지 않으면 yourmexample이 올바른 것입니다. 이 전략에 특별한 문제가 있습니까? 여기

당신은 일괄 호출 형태로 배치 relization의 내 샘플을 볼 수 있습니다
