Favorites 2.1 Saved
When placed within the {exp:weblog:entries} tag, this tag lets you use a conditional to determine whether a given entry has been saved by the currently logged in user.
Parameters
{exp:favorites:saved entry_id="{entry_id}"}
{if saved}
<p>You have already saved this link.</p>
{/if}
{if not_saved}
<p>Do you want to save this link?</p>
{/if}
{/exp:favorites:saved}
entry_id
entry_id = "some_entry_id"
The 'entry_id' parameter allows you to override the entry id or url title pulled from the url of the page. In those cases where your page shows a number of weblog entries, for each of which you want to display a favorites count, you should supply this parameter by feeding into it the entry_id variable from your weblog:entries tag. Like this entry_id="{entry_id}".
Conditionals
saved or not_saved
{if saved}
<p>You have already saved this link.</p>
{/if}
{if not_saved}
<p>Do you want to save this link?</p>
{/if}
{/exp:favorites:saved}
Any standard EE conditional format can be used with these two variables. These variables are only available for use in conditionals -- they are not available as stand-alone variables.
