Hello, I'm having a hard time displaying different text in a view
depending on if a user who is logged in has marked the post as a
favorite or not.
Users can have many posts, posts belong to users.
Users can have many favorites, favorites belong to users and posts.
In my index view I loop through all posts and display the post.
Inside that I loop, I then loop through all the favorites of that
post. Remember sometimes a post may not have any favorites so the
$post['Favorite] array might be empty. I want to display different
text if the post is a favorite of the logged in user. I do this by
comparing the current favorite's user_id to the logged in user's id.
Where I run into problems is when a post is marked as a favorite by 2
or more users. When this happens the Favorite array for the post
associations contains multiple users and thus I end up with both of my
different texts being displayed instead of just one or the other.
So if the post is a favorite I want to tell the user its already their
favorite.
If the post is not a favorite, I want to display a button so they can
add it as a favorite.
And if they are not logged in, they get a link describing to them what
favorites are.
Here's my view code:
*******************************
<?php foreach ($posts as $post): ?>
<?php
// Check for logged in user
if ($logged_in): ?>
// Loop through the posts favorites
<?php foreach($post['Favorite'] as $favorite): ?>
<?php
// If favorite matches user id tell them its a
favorite
if ($favorite['user_id'] == $current_user['id']): ?>
***** ITS YOUR FAVORITE!!!! *****
<?php
else: ?>
*** BUTTON TO ADD TO FAVORITES ***
<?php endif; ?>
<?php endforeach; ?>
<?php
// Favorites array might be empty
if (empty($post['Favorite'])): ?>
*** BUTTON TO ADD TO FAVORITES ***
<?php endif; ?>
<?php else: ?>
// No logged in user. Display link to describe what favorites are
*** LINK Favorites Description ***
<?php endif; ?>
