Hook for when viewing single entry

Question

I'm in the process of building my 1st extension (oi!) and I need to find a hook that allows me to fire off a routine when a member visits a single entry page.

I have listing pages and single view pages - I only need the routine to fire when viewing single entry pages NOT listing pages.

The list of hooks is extensive but I cannot seem to find one that fits.

The broad picture is:

I have an extension that relies on hooks to update the DB when ever a member adds a reply or adds a new entry. It gets a list of active users in the last 2 weeks, adds their member_id to Solspace 'Favorites' table in the DB in a separate collection.

This is working as expected as I can call the 'fav' module to mark entries on a list view page as 'unread'.

What I now need to do is when a user visits an entry, remove their member_id from the 'fav' table/collection. Someone adds a new comment/entry, it re-adds their member_id and marks the entry as 'unread' once again.

I believe the best approach is to make a module that I can call in the template code within the entry template to remove the user from the 'fav' DB table.

Answer 1

Crelate a plugin containing single function, say, function_name. The plugin will accept member_id of logged in visitor

ee()->session->userdata('member_id') 

and ID of entry being viewed, passed as parameter

ee()->TMPL->fetch_param('entry_id)

In this function, if member_id is not 0 (i.e. member is logged in), perform a check against your database table and if necessary, perform an update.

(Since there is DB interaction, someone might say you should create module, but since this is your first EE add-on and it has no settings, keep the things simple).

Then, in your single entry template, inside channel entries tag, call the plugin like this:

{exp:plugin_name:function_name entry_id="{entry_id}"}
