Hi there,
On my Drupal site, members can post their own content.
How to prevent them from creating a page with a title or a content that already exist ?
How to display a list of topics that have already been posted ?
Example : if someone try to create a "Ferrari F430" page and that "F-430 - Best Ferrari Ever" already exists, I want Drupal to display in a box, when the member starts writing is title :
"Are you sure this article is different from :
- F-430 - Best Ferrari Ever (with a link to the node)
- etc..."
Hope you'll help me.
Many thanks
