我在构建drupal自定义节点类型时遇到了一些麻烦。我创建了一个模块sj_highcharts，最终将使用highcharts api来提供数据图表。这个模块的目的是创建一个节点类型，它将显示一个表单，供人们与图表api连接，将数据存储在某些数据库表中，然后最终输出图表。
问题是我的hook_insert函数甚至hook_validate函数在表单提交后没有被调用，也没有任何东西被存储到数据库中。我已经说出了陈述，以确保它们不会发射。
代码：
/*
* Implementation of hook_node_info().
*/
function sj_highcharts_node_info() {
//defining one node type: 'sj highchart'.
return array(
'sj_highcharts_element' => array(
'name' => t('Highchart Element'),
'module' => 'sj_highcharts',
'description' => t("An element that creates a dynamic chart from specified data."),
'has_title' => FALSE,
'has_body' => FALSE,
'locked' => TRUE,
)
);
//In order to make this an element type, we will have to check the "is element" field in the content type administration page.
}
/**
* Implementation of hook_form().
*/
function sj_highcharts_form($node) {
$type = node_get_types('type', $node);
$form['delimiter'] = array(
'#type' => 'radios',
'#title' => t('Data Delimiter'),
'#description' => t('The character in which the data is delimited.'),
'#options' => array(t('Tab'), t('Space'), t('Comma')),
'#default_value' => '',
);
$form['x_label'] = array(
'#type' => 'textfield',
'#title' => t('x-axis label'),
'#description' => t('The label to be set and displayed for the x axis.'),

我一直在盯着这个工作日，但找不到问题。对此的任何指导都会很棒。谢谢布兰登
答案 0 :(得分：0)
查看examples模块中的node_example子模块。它应该有助于指明你正确的方向。
你的帖子不清楚你正在使用哪种版本的drupal。在Drupal 6中，您可以直接向表单或表单项添加其他验证和提交函数。
例如：
$form['delimiter'] = array(
'#type' => 'radios',
'#title' => t('Data Delimiter'),
'#description' => t('The character in which the data is delimited.'),
'#options' => array(t('Tab'), t('Space'), t('Comma')),
'#default_value' => '',
'#validate' => array('_name_of_custom_validation_function'),
'#submit' => array('_name_of_custom_submit_function'),
);
