Node “interest” notification in drupal

Question

My question is quite simple (i think) but cannot find the right module for that.

I'm working on a small classified website in which i have a bunch of nodes. I display them using views.

I'd like for any (authenticated with role) user of the website to be able to click on a kind of button like "I'm interested" which will trigger an event doing various actions like 'changing one cck field' on that content-type and also send an e-mail to the author of the classified.

Pretty straight forward but no clue on where to start, which module should i use ?

Answer 1

For this, you can use the Flag Module and Rules Module

In your view, you can create a relationship to flags to allow the use of other 'fields'.

Using Rules, create a new rule that is triggered when a node is flagged (or unflagged). Rules allows you to do both: changing a CCK field and sending out emails when an event occurs.

Walk-through:

1. Install and enable the Flag Module and Rules Module
2. Create a new flag at "admin/build/flags"
3. Edit/Create you classified view, add a relationship to Flags: Node Flag and choose > the name of the flag you just created.
4. Under "fields" add Flags: Flag link and configure as you like
5. Add a new rule at "admin/rules/trigger/add" for the event A node has been flagged,
under "FLAG NAME" A node has been flagged,
under "FLAG NAME"
6. Add action to perform of Populate a field under the heading CCK
7. Add action to perform of Send a mail to a user under the heading System and configure your desired settings.

Then when a user clicks the "interested" flag a field will be populated and email sent.
