Hi, Anca,
Thanks very much for your response, I understand how data are saved to
database now, but I got another question:
In the following code from BlogPostSheet
<dl>
<dt>$msg.get('xe.blog.sheet.title')</dt>
<dd>$doc.display('title', 'edit', $entryObj)</dd>
<dt>$msg.get('xe.blog.sheet.content')</dt>
<dd>$doc.display('content', 'edit', $entryObj)</dd>
<dt>Feature ID:</dt>
<dd>$doc.display('FID', 'view', $entryObj)</dd>
<dt>Package ID:</dt>
<dd>$doc.display('PID', 'view', $entryObj)</dd>
<div class="clearfloats"></div>
</dd>
</dl>
If I change the 'view' to 'edit' for both FID and PID, then both of FID and
PID will be saved to database, and I can query retrieve them, but I have
use view, then they are not saved to database. the problem is I donot want
these two fields editable, so I have to use view, any workaround for this?
so the bottom line is I want them to be saved to database and not editable
from the inline form.
'view' display only prints those values as text, not as form elements,
so it's normal that the values don't get back to the database. You
should display them again with 'hidden' as the display mode, which will
create hidden input elements with their current value.
Still, I hope you're not using those parameters as something secure,
since any attacker could just send any value he wants to the server;
always make sure security is thoroughly implemented on the server, never
trust data from the client.
Thanks again for your help.

Hi Dave,
You should read http://platform.xwiki.org/**xwiki/bin/view/DevGuide/**
Architecture<http://platform.xwiki.org/xwiki/bin/view/DevGuide/Architecture>,
but I understand that it might be cryptic for a first time usage so here
we go:
must know that xwiki is a java engine, so there is some java code that
does things, it's not all done in velocity.
Basically, there is a java "platform" that can handle documents, objects
in documents, classes, etc (load, save) and then there is the velocity
scripting that you can do in wiki pages which **uses** this core (injected
variables like $xwiki, $doc). See here about how this scripting in pages
works:
http://platform.xwiki.org/**xwiki/bin/view/DevGuide/**Scripting<http://platform.xwiki.org/xwiki/bin/view/DevGuide/Scripting>.
Also, there are some interesting information about the data model here
http://platform.xwiki.org/**xwiki/bin/view/DevGuide/**DataModel<http://platform.xwiki.org/xwiki/bin/view/DevGuide/DataModel>.
The 'platform' project on git contains all this 'platform' code: java
sources, default templates, default js, css, etc, which you can enhance in
wiki pages (but we don't do everything in wiki pages, so you should not
look for it only in wiki pages).
Also, there are a bunch of "default" velocity templates that handle the
default layout and actions for the wiki (in the webapps/xwiki/templates
folder of the installation). For example, the save and view button is
generated by these templates, along with the url to which the data in the
form is posted.
I recommend firebug and LiveHttpheaders extensions of firefox to study
what data is posted to which URL, etc what data is received. from then on,
with the help of http://platform.xwiki.org/**xwiki/bin/view/DevGuide/**
Architecture#**HUnderstandinghowHTTPrequestsa**rehandled<http://platform.xwiki.org/xwiki/bin/view/DevGuide/Architecture#HUnderstandinghowHTTPrequestsarehandled>,
you should be able to find the code that actually does the save.
Have fun,
Anca

Hi, all
I am studying the BlogClass, BlogPostClass, I checked the Blog.BlogCode,
there are alot of velocity scripts, I can see the search documents from
db,
but could not find any code related to insert document records into
database, so how is the document created from blog saved into database?
please point me to the script code in the Blog.BlogCode.
Thanks
Dave
