Hey Nigel,

Did you find a suitable solution to this?

Hi Michael

No sorry - I have identified an alternative solution.

Regards

Nigel

As it happens, I have blogged about this a couple of weeks ago...

http://refactored.com.au/blog/2010/10/19/blog-categories-in-blog4umbraco-take-two

There's a code download packaged up for umbraco 4.5 listed on the page.  Took me a couple of tries to get this working the way I wanted, but now I have multiple blogs each with their own set of tags. I also had to modify the Blog document type a little to work this out.  No modifications were needed to the base blog4umbraco package though.

Hope this helps...

Hi Owen,

Take a look at the followup Blog entry here:

http://our.umbraco.org/projects/collaboration/blog-4-umbraco/using-blog-4-umbraco/13884-Multiple-Blogs-and-Tag-Clouds?p=0#comment56638

It deals specfically with this issue...

Rob.

Big Whoops.

Hi Robert,

Thank you that is exactly what I am looking for.

I'm still having some problems getting it going, I have added your XSLT modifications and I am currently getting 0 tags.

I took a peek in the cmsTags table in the DB and I have 7 tags. They have an "id" "tag" values but "parentId" is null for all, and "group" is blank for all.

I started to use your implementation from Part 2 (skipping the Categories bit).

Here are my XSLT's:

Any help would be great!

Hi Owen,

Have you taken a look at the preceding article about adding a Category to the blog?

http://refactored.com.au/blog/2010/10/18/adding-a-blog-category-to-blog4umbraco

It provides a little more background on the whole Blog category issue, but importantly provides a necessary step for getting BlogTags to work properly.  Only the first half of the article is relevant (adding the Category attribute to the Blog document type).

I'm going to have to formalise the documentation before I release the project to the Our.Umbraco project repository I think...

Resolved

Woo!

Had some more problems as your XSLT were designed for 4.5 and since im running 4.0.3 I had to make some changes.

Thanks,

Owen

Hi Owen,

Great work getting the 4.0.3 version of the XSLT files working... try looking in the cmsTags database table... it's possible you have the same tag in the table twice, one will have a null group field.  If you had posts tagged with the same tag before the changes, they most likely are referencing the default tags.  You may have to update those posts by removing all tags, then re-adding them.  If the tags aren't visible, you'll need to either mess around with the database, or change the property's datatype back to the default Tags datatype temporarily.

Hope this helps, my head is stuffy with a cold at the moment, so probably not explaining myself clearly...

Rob.

Hi Robert,

Thanks again! I figured out my problem as it was a conflict with passing params to the XSLT.

For anyone who's interested here are the 4.0.3 XSLT files for Roberts implementation.

Last couple days have been consumed with trying to separate two Blogs in one Umbraco installation. Finally have a working version. Lots of toying with Tags, Comments, and Templates! Hopefully one day this will be supported with the original Blog4Umbraco package!

Thanks again,

Owen

Hi Robert,

One more questions. I have now moved this over onto my live server and it is working great! However with old "Tags" I can't get those to display. I added the Category to the exisiting Blog Root node, went into the database and changed the "group" to match that of Blog Root Node but the old tags won't display, if i create a new post with tags then those will appear properly. Is there another setting in the DB that I need to change?

Thanks,

Owen

Hi Owen,

The query that getAllTagsInGroup uses is as follows:

SELECT cmsTags.id, cmsTags.tag, cmsTags.[group], count(cmsTagRelationShip.tagid) AS nodeCount FROM cmsTags
                            INNER JOIN cmsTagRelationShip ON cmsTagRelationShip.tagid = cmsTags.id
                            INNER JOIN cmsContentXml ON cmsContentXml.nodeid = cmsTagRelationShip.nodeId
                            WHERE cmsTags.[group] = @group
                            GROUP BY cmsTags.id, cmsTags.tag, cmsTags.[group]

However, depending on how many old posts you have, the simplest solution may be to remove and re-apply the tags to them?

Hope this helps,

Rob.

I'm currently trying to use this setup......we're having one major problem though.

We've followed all the steps, created the categories for each blog, put in the 'blog tags' extension, and changed the BlogCategories.XSLT file to the new one (will do the tag cloud one later)......it works, however... if you try and add tags to your blog post before it has been published, it sets the tags to the group 'default' rather than the specific category group it should belong to.

Adding it after it has been published results in it being in the right group, but this is not practical from a user perspective as it means locating your blog post node in the tree and adding your tags in that way.

Does anybody have any ideas as to why this maybe happening?

We're using Umbraco Version 4.6.1

Thanks

Sam

I'm also having problems with this. I've posted on the Refactored website and on the package forum but no reply as yet.

My problem with tagging is basically the tags cannot be retrieved.

I do the following:

• Create blog and add a category
• Create a post and add a tag (everything works up to this point, post gets tag in correct group, all works on front end and everything looks good in DB)
• When I go back into the post in Umbraco the tags cannot be retrieved (none are displayed) although they still appear in the DB
• If I republish, the filter by functionality on the front end stops work (everything still in place in DB)
• If I try and add the same tag again its add it but I can see in the DB it creates a new tag with the group 'default'

I've been banging my head against a wall for a couple of days with this now and the deadline for completing the site is looming.

Has anybody had similar problems? Had this working successfully or have any advice?

Thanks in advance

Ben

Hi Ben,

I'm currently looking into the issue that you reported.  How long ago did you download the extensions package?

Thanks for the reply Rob, much appreciated.

Downloaded it either yesterday or the day before. Its looks to me like the save is working correctly because the tags get inserted into the cmsTags table with the correct group. I've used Reflector to look through the code and think it could be a problem within the OnInit method in umbraco.editorControls.tags. I'm not sure if or where the group is set here to retrieve the tags for this group.

Thanks for the reply Rob, much appreciated.

Hi Ben,

I've resolved the issue and uploaded a new version of the package for you to try out.  Please let me know if you find any other issues and I'll look into it.

Rob.

Hi Rob

That seems to have worked.

Thank you very much, much appreciated.

Ben

Hi all,

Can any one help me out what are the steps i need to follow to make this issue resolve in umbraco 4.5 version.I am stuck with this issue since 4 days. i am unable to figure out the coorect way to make it work.

Can any one please guide me in resolving the tags issue.

Thanks
