我的節點類型不會顯示它的字段

Question

我想創建我的第一個創建簡單節點類型wcNames的drupal模塊。此節點類型有兩個字段，名字爲&姓氏。 我可以讓我的模塊創建節點類型的數據庫表，並將其添加到node_type表中，但是當我打開node/add/wc-name字段時，名字和姓氏不會出現。 以下是我的代碼。請建議。

<?php 
// wc_name.install file 
/* 
* hook_schema Implementation: Creates the DB and it's fields 
*/ 
function wc_name_schema(){ 
    $schema['wc_name_names'] = array(
    'fields' => array(
     'nmid'    => array('type' => 'serial', 'unsigned' => TRUE, 'not null' => TRUE), 
     'firstname'  => array('type' => 'varchar', 'length' => 50, 'not null' => FALSE), 
     'lastname'   => array('type' => 'varchar', 'length' => 50, 'not null' => FALSE), 
    ), 
    'primary key'  => array('nmid'), 
    'unique keys'  => array(), 
    'indexes' => array(
     'nmid'  => array('nmid'), 
    ), 
); 
    return $schema; 
} 

//function wc_name_install(){ } // Use this function to set variables for the module. 

function wc_name_uninstall(){ 
    //unset variables if any set 

    // Delete all wc_name nodes 
    db_delete('node')->condition('type', 'wc_name')->execute(); 

    // Delete all wc_name tables 
    db_drop_table('wc_name_names'); 
} 
?> 

<?php 
// wc_name.module 
/* 
* Implementation of _node_info(): define node 
*/ 
function wc_name_node_info(){ 
    return array(
    'wc_name' => array(
     'name' => t('wcName'), 
     'base' => 'wc_name', 
     'base' => 'page', 
     'description' => t("A smaple module to save names."), 
     'has_title' => TRUE, 
     'title_label' => t('Title'), 
     'has_body' => FALSE, 
    ) 
); 

} 

function wc_name_menu() { 
    $items = array(); 
    $items['wc_name'] = array(
    'title' => 'wcNames', 
    'page callback' => 'wc_name', 
// 'access arguments' => array('access wcNames'), 
); 
} 
?> 

<?php 
// wc_name_form.inc 
function wc_name_form($node, &$form_state){ 

    // Add fields 
    $form['first_name'] = array(
    '#type' => 'textfield', 
    '#title' => t('First name'), 
    '#required' => FALSE, 
    '#default_value' => $node->wc_name['firstname'], 
); 

    $form['last_name'] = array(
    '#type' => 'textfield', 
    '#title' => t('Last name'), 
    '#required' => FALSE, 
    '#default_value' => $node->wc_name['lastname'], 
); 
    return $form; 
} 
?> 

我錯過了什麼？

試試這個：

function createTextFieldByName($type, $fieldname, $fieldlabel) 
{ 
    $field = field_info_field($fieldname); 
    if (empty($field)) { 
     $field = array(
      'field_name' => $fieldname, 
      'type' => 'text', 
      'entity_types' => array('node'), 
      'translatable' => TRUE, 
     ); 
     $field = field_create_field($field); 
    } 

    $instance = field_info_instance('node', $fieldname, $type); 
    if (empty($instance)) { 
     $instance = array(
     'field_name' => $fieldname, 
     'entity_type' => 'node', 
     'bundle' => $type, 
     'label' => $fieldlabel, 
     ); 
     $instance = field_create_instance($instance); 
     return $instance; 
    } 

    return null; 
} 

$type = 
array(
     'type' => 'MY_TYPE', 
     'name' => t('NAME'), 
     'base' => 'node_content', 
     'description' => t("DESCRIPTION"), 
     'custom' => 1, 
     'modified' => 1, 
     'locked' => 0, 
); 

$type = node_type_set_defaults($type); 
node_type_save($type); 

createTextFieldByName($type,'firstname','First name'); 
createTextFieldByName($type,'lastname','Last name');
