[SOLVED] CB Auto Action ?

Hi, I would like to expose a my necessity and to understand if can do it with Community Builder and some of its components, I thought CB Auto Action. I have two types of users (eg student and professor). These, after the login on the site, through a list have the chance to see all registered users and their profiles (that is, students can see only the profile of professors and vice versa, but they can not see their own profiles (that is the student does not see the profiles of the other students, the same the professor). Newly registered users can view their profiles, but it contain only limited information (for example, the matter of the teacher and school). Would that, after the student has contacted the professor, for example with the exchange of a message (eg Uddeim) they can see their profiles in the full version (with more information, such as the school, matter, teacher's name, phone, e-mail, etc.). I thought to create two profiles (one with little information and one complete) and two groups for the same type of user, and manage them with access levels, meaning: if the contact between the parties has not happened, always displays the profile 1 (with limited information), if the contact has occurred, displays the profile 2 (full information).
But at login in the list should be displayed for all users, both, contact and non contact and of course the users not contacted can not see the complete profiles.
Thanks for any suggestions and help.

You could use CB Privacy then set your tabs/fields to be moderator privacy controlled for Connections only. Then for the student to see the teachers profile the teacher would need to accept a connection request from the student as the various tabs and fields are only accessible to connections. To prevent students from seeing other students you could use a CB Auto Actions redirect action on the profile display trigger to try and send them away if the user is a student usergroup and the viewing user isn't the displayed profiles owner.

Is it possible with CB Auto Action during the registration process check if a textbox contains a word contained in a text area? Example: if the text field contains "Rome" and the textarea field contains "City of Rome", a warning message appears.
Thank you.

Warning message to appear where? Like dynamically as they type? Yes, that's doable if my assumption is correct. You'd need to use the before registration form trigger in a Code action with Method set to jQuery then write some jQuery to do what you're wanting.

During the registration in the textbox city I enter "Rome", after in the description field that is a text area, insert "Rome is the capital of Italy", now I would like to receive an alert Example: "In the description it is not possible to insert the name of the city"(it's good also using onBeforeRegisterForm), because Rome has been included in the description. I also found this post:
www.joomlapolis.com/forum/153-professional-member-support/191087-verify-email-with-cb-auto-action-on-registration?start=6
here check that the contents of the two fields is the same e-mail, is it possible adapt it using "Does Contain" instead of "Not Equal To"?
Thank you.

No, that's a jQuery Validate rule. It has no support for "Does Contain". You'll need to write custom jQuery for what you're wanting then append it to the registration page using CB Auto Actions.
