#2692 – move articles to a other category

Hi

Actually, I would suggest the following instead:

After moving the article to a new category, find that Article URL record in sh404SEF manager, take a note of the SEF URL, and then delete the record - with all duplicates.

Then go to the new record and add the old SEF URL as an alias.

This will prevent some old URLs staying in the database.

Hi

Just when I do that, the modified article goes to the home page...

It does not go to the home page. It displays using the home page template because... the Iitemid in the non-sef URL is not the right one. Same as previous ticket.

Hi

There is no false link, at least none created by sh404SEF. As explained last time:

NON-SEF URLs are created by Joomla and extensions on your site.

SO:

1 - search for les-fonds-d-ecran/le-fond-d-ecran-d-aout in the URL manager
2 - Look at the corresponding non-sef URL. What is its Itemid? is it the correct one, for this menu item you are using?
Probably not. Then select the right one in the list of duplicates. If there is not duplicate, delete that URL, then maybe next time your site will not use the wrong Itemid.

Hi

but here the catid is not correct, must be 105

Which is why I told you above to "...delete the record - with all duplicates. "

If you indeed delete all those links in the URL manager, then it means you still have on your site non-sef links with the wrong category. Now if you added links to that article with the category mentioned in the non-sef URL, you will have to fix them as well (and after fixing them, delete all those bad URLs from the URL manager).

Hi

There is no procedure I can think of. What's happening is not happening in sh404SEF, and there is nothing I can outline to do to prevent it.

Fixing things is a matter of selecting the correct non-sef URL, but preventing it requires that we know where those URLs with wrong Itemid are created, and that's not something I can do.

Here is how Joomla and sh404SEF work:

- when there is a link somewhere on a page, a non-sef link, created either by Joomla, by an extension or by you in an article, Joomla finds it and passes it to sh404SEF to be recorded and transformed into a SEF URL.

For instance, if you have a link:

index.php?option=com_content&Itemid=529&catid=105&id=522&lang=fr&view=article

on the home page, Joomla passes it to sh404SEF. sh404SEF searches in the database to know if we have seen this URL before.
If found, it returns the current associated SEF URL. If not already seen, it builds the SEF (for instance /example-page) and stores both URLs in the database.

Now if later on, another non-sef is found by Joomla:

index.php?option=com_content&Itemid=529&catid=96&id=522&lang=fr&view=article

sh404SEF does not find it in the database. So it builds the SEF, and the SEF is also /example-page. It means this is a duplicate, and it's also stored in the databases, but marked as #2 duplicate.

So in this case you can see the non-sef URL, with catid=105, was left over in the database from the time the articles where in that category.

Another consequence is that whatever non-sef URL is the first one takes the main spot. All others are considered duplicates.

And here, I don't have the right one URL.

blog/graphisme/un-projet-bd



index.php?option=com_content&Itemid=529&catid=97&id=529&lang=fr&view=article

index.php?option=com_content&id=529&lang=fr&view=article

You mean you don't have a link with the right category, the new one? was this an article that was changed category?

If so, it means until now Joomla never saw the correct link on any page that was displayed to a user. So just displaying a page with a link to that blog is enough for a URL to be created.
Again, I am not saying that you should try to display /blog/graphisme/un-projet-bd. You should (or a user should request) a page with a link to /blog/graphisme/un-projet-bd

Hi

But how many times this error'll be appears ?

There is no error from sh404SEF side. The errors, if any, are caused by creating incorrect non-sef URL being created.

For me now, I think it is simple to change URL,... but impossible to explain that to a customer, ins't it ?

Certainly hard to do. The fix is in only creating correct non-sef URLs, which might be tricky, because it depends on the extensions and modules you use, and even Joomla is not doing it correctly all the time.
In last version, we introduced a new feature under the "By component" tab of sh404SEF, that may help. Two columns were added:


On the first, one you can select to force an Itemid. On the next column, you can select which menu item to use.

I would suggest you set com_content to "Override if missing", and select your blog menu item in the next dropdown. That should fix at least some, if not all of the issues you mention here.
Be sure to test when changing that setting, in case of side effects on other pages.
