[英]Creating new node type with custom field makes page for adding the node without any fields in Drupal 7
我正在尝试为新节点类型“ synopsis_book”创建一个简单的自定义字段“ field_book_year”。 我在.install文件中写过:
function synopsis_install() {
node_types_rebuild();
$types = node_type_get_types();
// In Drupal 7 you must explicitly add a "body" field when you create a custom content type,
// thus the call to node_add_body_field($types['newsletter']);.
node_add_body_field($types['synopsis_book']);
$body_instance = field_info_instance('node', 'body', 'synopsis_book');
$body_instance['type'] = 'text';
field_update_instance($body_instance);
field_create_field(array(
'field_name' => 'field_book_year',
'label' => t('Company posting the job listing'),
'type' => 'text',
'translatable' => TRUE,
)
);
field_create_instance(array(
'field_name' => 'field_book_year',
'label' => t('Company posting the job listing'),
'entity_type' => 'node',
'bundle' => 'synopsis_book',
'type' => 'text',
'widget' => array(
'type' => 'text_textfield',
),
'display' => array(
'example_node_list' => array(
'label' => t('Company posting the job listing'),
'type' => 'text',
),
),
'description' => 'Begin Date',
)
);
}
然后,我在.module中具有以下功能:
function synopsis_node_info()
{$types = node_type_get_types();print_r($types);
return array(
'synopsis_author' => array('name' => t('Author'), 'base' => 'synopsis_author', 'description' => t('Author description, biography etc.'),
'has_body' => true, 'has_title' => true, /*'min_word_count' => 11,*/ 'help' => t('Enter blah-blah-blah'),
'title_label' => t('Author full name')
),
'synopsis_book' => array('name' => t('Book'), 'base' => 'synopsis_book', 'description' => t('Book description, synopsis etc.'),
'has_body' => true, 'has_title' => true, /*'min_word_count' => 11,*/ 'help' => t('Enter blah-blah-blah'),
'title_label' => t('Book title')
),
);
}
/**
* Implement hook_form() with the standard default form.
*/
function synopsis_book_form($node, $form_state) {
return node_content_form($node, $form_state);
}
/**
* Implements hook_validate().
*/
function synopsis_book_validate($node)
{
// Enforce a minimum character count of 2 on company names.
if (isset($node->field_book_year) &&
strlen($node->field_book_year['und'][0]['value']) < 2
) {
form_set_error('job_post_company',
t('The company name is too short. It must be atleast 2 characters.'),
$limit_validation_errors = NULL);
}
}
不管我写了什么,添加书的页面看起来都是这样! 没有“ field_book_year”字段。 甚至没有身体
我究竟做错了什么? 谢谢。
我认为您遇到的问题是在创建节点类型之前 , 在安装模块时运行hook_install
。 因此,从本质上讲,您正在尝试将字段附加到不存在的节点类型上。
我一直这样做的方式是在尝试附加字段之前在hook_install
创建节点类型(这是提供testimonial
内容类型的模块的示例):
// Make sure a testimonial content type doesn't already exist
if (!in_array('testimonial', node_type_get_names())) {
$type = array(
'type' => 'testimonial',
'name' => st('Testimonial'),
'base' => 'node_content',
'description' => st("Use <em>basic pages</em> for your static content, such as an 'About us' page."),
'custom' => 1,
'modified' => 1,
'locked' => 0,
'title_label' => 'Customer / Client Name'
);
$type = node_type_set_defaults($type);
node_type_save($type);
node_add_body_field($type);
}
// See if the testimonial date field exists
if (!field_info_field('field_testimonial_date')) {
field_create_field(array(
// Field info here
));
}
// If the date field is not attached, attach it
if (!field_info_instance('node', 'field_testimonial_date', 'testimonial')) {
field_create_instance(array(
// Field instance info here
));
}
如果您查看标准安装配置文件的安装文件,您将看到这实际上是Drupal核心执行此任务的方式,因此我希望这是“正确”的方式。
