[opencms-dev] Antwort: Re: How to write into Frontend User-Forms?

[Mathias Lin]

Hi Frank,

the html form is probably a jsp template and it does not contain any 
data of your phone book entry (maybe your phonebook entry elements are 
just making use of this template to display the data together with the 
input form to allow the user to change the data, but I don't know how 
you configured your xsd/content type here).
Your phonebook entry elements are files that contain the actual data, 
and it's xml structure is defined by your phoneBookEntry.xsd.


Below is a code snippet:


Locale locale = Locale.GERMAN;
String dataDir = "path/to/phonebook/_data/";
String filename = "/" + dataDir + "entry." + 
Calendar.getInstance().getTimeInMillis() + ".html"; // or use any other 
logic to create the file name

CmsObject cmsObject = 
OpenCms.initCmsObject(OpenCms.getDefaultUsers().getUserGuest());
cmsObject.loginUser("AdminOrOtherUserWithWorkplacePermission", 
"HisPassword");
cmsObject.getRequestContext().setSiteRoot(OpenCms.getSiteManager().getDefaultSite().getSiteRoot());
cmsObject.getRequestContext().setCurrentProject(cmsObject.readProject("942c4f84-e610-11dd-8e8a-85b622eae7ae") 
);  // <-- needs to be UUID of the offline project

CmsResource document = cmsObject.createResource(filename , 1011);   // 
<--- 1011 just an example, this id the ID of your phonebook-entry.xsd 
(as of opencms-modules.xml)
CmsXmlContent xmlContent = CmsXmlContentFactory.unmarshal(cmsObject, 
document, request);      
xmlContent.getValue("Title", locale,0).setStringValue(cmsObject, 
request.getParameter("title")) ;     // depending on your form 
validation, you might need to check for NULL values here
xmlContent.getValue("FirstName", locale,0).setStringValue(cmsObject, 
request.getParameter("firstName"));
xmlContent.getValue("LastName", locale,0).setStringValue(cmsObject, 
request.getParameter("lastName"));
// ...

xmlContent.getFile().setContents(xmlContent.marshal());
cmsObject.writeFile(xmlContent.getFile());
cmsObject.unlockResource("/" + dataDir + document.getName());


Regards,
Mathias
