Ditto blog - tags for posts - and how to have them on a web-entry page?

I have a Ditto call

[[Ditto? &id=`myDittoCall` &startID=`2` &summarize=`6` &removeChunk=`Comments` &tpl=`ditto_blog` &paginate=`1` &extenders=`summary,dateFilter` &paginateAlwaysShowLinks=`1` &dateFormat=`%a %d %B %Y` &tagData=`documentTags`]]

that works fine and dandy and gives me what I want.

The ’tags’ are entered via TV - but I would like to also be able to add them to the blog ’add an entry’ page.

I have an ’Input Form for creating new blog entries’ as a Chunk and can add a field - but can’t figure out what to put in as the values, so they enter the database - the below doesn’t work.

<label for="tags">Tags: <input name="tags" id="tags" type="text" value="[+tags+]" size="40" /></label>

Probably really straight forward but I can’t figure it out!

thanks

Also - how do you add a field, so as to put images into the blog entry?

How are you adding your blog entry ?
Are you using NewsPublisher snippet ?

Via a page created using NewsPublisher - here is the snippet;

[!NewsPublisher? &folder=`2` &canpost=`Site Admins` &formtpl=`FormBlog` &footertpl=`Comments` &makefolder=`1` &rtcontent=`tvblogContent`!]

NewsPublisher snippet can not handle TVs.
If you want to handle TVs from the frontend, I suggest you to use FDM.
