It is called Joomla Article field and is not included in the core since Seblod 3.8., you need to install it separately (it is free)

In select dynamic query you can use syntax:

• $user->property (replace property with desired property name, id in your case) and
• $uri->getValue('some_variable'), in your case this would be something like$uri->getValue('catid') if category id is present in the url as catid value.

Thank you!

It works almost like I would. In the dynamic select there are displaying all the user's article and I would just the user's article of a specific categorie (catid = 10).

In the option value I tried to put id and catid but it didn't work there were all the user's articles.

You need to actually have category id in the url to be able to use it dynamically . If this is a fixed id just add it the query where statement e.g. WHERE catid=10

Hi,

Thank you for your answer. I wrote this query and it work well :

SELECT title FROM #__content WHERE catid=10 AND created_by=$user->id

I use the AND to complete the WHERE on the catid.

I hope it will help somebody in hurt like I was.
