Problem: I would like Users to be able to choose certain posts as favorites. They should also be able to remove them from favorites.
Solution:
Create a repeating numeric field on your post type called "favorites". This field will be updated to add the current User's ID when they select a favorite. When they unfavorite a post, this field will be updated to remove their ID.
Create a CRED form that allows you to modify the posts that can be favorited. Remove all the content from the CRED form and replace it with the following code:
[credform class='cred-form cred-keep-original']
[wpv-conditional if="( [toolset_is_favorite id='[wpv-post-id]'] eq '1' )"]
[cred_generic_field field='remove-favorite' type='hidden' class='']
{
"required":0,
"validate_format":0,
"default":"1"
}
[/cred_generic_field]
[/wpv-conditional]
[cred_field field='form_submit' value='Favorite' urlparam='' class='x-btn x-btn-global mam']
[/credform]
Add the following JavaScript to your CRED form's JS panel:
jQuery(window).bind("load", function() {
jQuery( "form[id^='cred_form_368']").find("input[type='submit']").val(jQuery( "input[name='remove-favorite']").length ? "Remove from Favorites" : "Add to Favorites");
}
)
This code will toggle between showing "Add to Favorites" and "Remove from Favorites" as the button name.
Add the following PHP to your child theme's functions.php file:
add_action('cred_save_data_368', 'sda_user_favorites',10,2);
function sda_user_favorites($post_id, $form_data) {
if( isset($_REQUEST['remove-favorite']) ) {
delete_post_meta($post_id, 'wpcf-favorites', get_current_user_id());
} else {
add_post_meta($post_id, 'wpcf-favorites', get_current_user_id(), false);
}
}
/* Favorites shotcode for use as a conditional */
add_shortcode( 'toolset_is_favorite', 'toolset_is_favorite_func');
function toolset_is_favorite_func($atts)
{
global $wpdb;
$post_id = $atts['id'];
$user_id = get_current_user_id();
$favorites = $wpdb->get_results( "SELECT * FROM wp_postmeta WHERE meta_key = 'wpcf-favorites' AND post_id = $post_id AND meta_value = $user_id LIMIT 1");
return sizeof($favorites) ? 1 : 0;
}
Be sure to add the toolset_is_favorite shortcode in Toolset > Settings > Frontend content > 3rd party shortcode arguments.
Place the CRED form in a View of posts, or in a Content Template for these posts.
