Question

我正在尝试验证一组节点，然后再将它们保存到数据库中：

foreach ($nodes_to_save as $node) {
    if (! (node_validate($node, $form))) {
        form_set_error('', t('Node %title did not validate. No nodes were saved.', array('%title' => $node->title)));
        $success = FALSE;
        break;
    }
}

node_validate的文档说它将调用form_set_error()来指示节点未验证的原因。但是，上述代码不会发生这种情况。我得到的只是我手动设置的错误。我做错了什么？

Answer 1

这不会更有用吗？

$success = true;
foreach ($nodes_to_save as $node){
    node_validate($node);
    //returns null or array
    $errors = form_get_errors();
    //if there was an error, send an extra message indicating the node that was not saved
    if($errors){
        form_set_error('', t('Node %title did not validate. It was not saved.', array('%title' => $node->title)));
        $success = false;
        break;
    }
}

而不是将$success作为FALSE返回给通过循环运行的每个节点？

试试这个 $form应该是一个数组！

foreach ($nodes_to_save as $node) 
{
    if (! (node_validate($node, $form))) 
    {
        form_set_error('', t('Node %title did not validate. No nodes were saved.', &drupal_static(__FUNCTION__));
        $success = FALSE;
        return $success;
    }
}

或者不要使用if beause node_validate doesnt return true或false;

foreach ($nodes_to_save as $node) 
{
       node_validate($node, $form);
        $success = FALSE;
        return $success;
    }
}

请注意，node_validate将第一个参数作为对象，第二个参数作为数组
