Hi,
in Visforms a detail view is the view of the details of exactly one record set (form submission). As far as I understand your description, actually each introduction would be a separate form submission so there is no detail view of all introductions but only a detail view for each introduction. Please correct me, if I misunderstood your description.
Nevertheless, I think there is a solution to your problem, if the users, who makes the introductions are logged in, when they make the submission.
There is the Content Plugin Data View, that comes with the Visforms Subscription. The major aim of this plugin is, to allow you more specificly to select which record sets are displayed. For example you can set it up in a way, that it will only display the record sets that where submitted by the currently logged in user. Further on this plugin comes with two different layouts and the layout which is called "list" there, could be used to display the details of all introductions of the logged in user in one (vertical) list. (The data of each record set are displayed as label/value pairs wis one label/value pair per row and the record sets are displayed one beneath another).
As it is a content plugin, you would create an article and display the selected introductions inside that article, using the plugin. Depending on who views the article, different record sets are displayed. And in the form configuration on the "Result" tab, you just set that article as redirect url.
As the plugin can only select logged in user by there name, username or email (from the Joomla! user data) you will maybe need one addtional field in the form with one of the three informations (if you do not already have an email field). You can set the field default value from the Joomla! user information by automatic action, in order to make sure, that it has the correct value and you can make it readonly, so that the user cannot change the value.
Please check out the Plugin Documentation for all the details.
Regards,
Aicha
