Usage

Once installed, settings are available by product class at the url: admin/store/products/power-tools

As of version 1.10 the default product node type is supported.

Power tools settings are configured for each class by clicking the edit action next to the associated product class, and can be enabled or disabled for each class as well.

how to make a textfield un editable?

Store Administration >> Configuration >> Cart Settings

and set:

1)hook_validate
2)hook_nodeapi时验证
2)下面的方法是比较好的

function mymodule_form_alter(&$form, &$form_state, $form_id) {
	switch($form_id) {
		case 'artist_node_form':
			$form['#after_build'][] = 'mymodule_custom_after_build';
			break;
	}
}

function mymodule_custom_after_build($form, &$form_state) {
	$form['#validate'][] = 'mymodule_custom_validation';					
	
	return($form);
}

function mymodule_custom_validation($form, &$form_state) {
	//My custom validations went here.
}

　　在普通情况下，当用户提交节点表单后会被重定向到对应的节点页面，如果在 URL 中传入了 ?destination=path/xxx 这样的参数，提交表单后用户就会被重定向到 destination 设置的页面。

　　除此之外，开发人员还可以通过为节点表单设置重定向属性，来控制表单提交后的重定向路径。

　　下面的代码通过应用 hook_form_alter()，判断当表单ID为"story_node_form"时，设置表单的重定向属性（#redirect）
