Mar*_*ark 6 drupal drupal-modules
作为对这个问题的更具体的看法:
如何在模块内检查节点是否是某种类型,以便能够对节点执行某些操作.
谢谢
上下文:
我正在尝试调整此代码,以便它不是在"my_page"上工作,而是在节点类型上工作.
function MYMODULE_preprocess_page(&$variables, $arg = 'my_page', $delta=0) {
// I needed a one hit wonder. Can be altered to use function arguments
// to increase it's flexibility.
if(arg($delta) == $arg) {
$scripts = drupal_add_js();
$css = drupal_add_css();
// Only do this for pages that have JavaScript on them.
if (!empty($variables['scripts'])) {
$path = drupal_get_path('module', 'admin_menu');
unset($scripts['module'][$path . '/admin_menu.js']);
$variables['scripts'] = drupal_get_js('header', $scripts);
}
// Similar process for CSS but there are 2 Css realted variables.
// $variables['css'] and $variables['styles'] are both used.
if (!empty($variables['css'])) {
$path = drupal_get_path('module', 'admin_menu');
unset($css['all']['module'][$path . '/admin_menu.css']);
unset($css['all']['module'][$path . '/admin_menu.color.css']);
$variables['styles'] = drupal_get_css($css);
}
}
}

谢谢.
在模块内部,您可以这样做:
if (arg(0) == 'node' && is_numeric(arg(1)) && arg(2) != 'edit') {
if (!($node)) {
$node = node_load(arg(1));
}
if ($node->type == 'page') {
// some code here
}
}

这将加载给定当前节点页面的节点对象(如果不可用).由于我不知道您正在使用的代码的上下文,这是一个粗略的示例,但您始终可以通过执行node_load(node_id)来查看节点的属性.但是,根据Drupal API函数,它可能已经为您加载.
例如,hook_nodeapi.
http://api.drupal.org/api/function/hook_nodeapi
你可以这样做:
function mymodule_nodeapi(&$node, $op, $a3 = NULL, $a4 = NULL) {
switch ($op) {
case 'view':
// some code here
}
}
