Question

我是Drupal的新手，但已经完成了创建小部件的任务。

模块加载，显示字段，但是当我创建一些内容时，在保存内容时不会存储表单值。

.install文件：

function cloudinary_field_schema($field) {    

  $columns = array(
    'publicID' => array('type' => 'varchar', 'length' => 255, 'not null' => FALSE),
    'url' => array('type' => 'varchar', 'length' => 255, 'not null' => FALSE),
    'caption' => array('type' => 'varchar', 'length' => 255, 'not null' => FALSE),
    'alt' => array('type' => 'varchar', 'length' => 255, 'not null' => FALSE),
    'credit' => array('type' => 'varchar', 'length' => 255, 'not null' => FALSE)
  );    

  return array(
    'columns' => $columns,
    'indexes' => array(),
  );    

}

.module文件：

/**
 * Implements hook_field_info().
 * define the field type
 */
function cloudinary_field_info() {
    return array(
        'cloudinary' => array(
            'label' => t('Cloudinary image selector'),

Answer 1

您需要在.install文件中实现hook_field_schema。

// Something like this 

function cloudinary_field_schema($field) {
 // $field['type']
 return array(
  'columns' => array(
   'column_name' => array(
    'type' => 'float',
    'size' => 'big',
    'not null' => TRUE,
    'default' => 0,
   ),
  )
 );
}

Answer 2

这是cloudinary_field_is_empty（）中的逻辑问题。它总是回归虚假。一切正常！谢谢你的帮助Zolyboy！
