Dieser Thread wurde gelöst. Hier ist eine Beschreibung des Problems und der Lösung.
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.

Hello Again Christian... I went back over everything again and perhaps I did not save after editing the wp-config file in my code editor. After saving I now see the "error_log.txt" file, apologies if this is a goof on my end. Below are the logs from the file after redoing all the steps in the previous thread post. Also it looked like everything was the same as I previously reported.
In addition to the contents of the Error Log file pasted below is a screenshot that represents the edited line of code in the functions.php file which is also the line 138 showing up as an error in the Error Log.
ERROR LOG

Hi Christian... I think I see what you are doing with this new code for the functions.php file but after inserting it along with the new conditional, things still are not working correctly. The toggle functionality is no longer working and even when I am just in User # 1, the button is adding instances to the Favorites field.
The field and form settings are as the have been and I entered the "toolset_is_favorite" into the Third-party shortcode area of Toolset Settings so I must have something misconfigured with the code somewhere. Below is all the code I am using in each of the areas, apologies if I am missing something obvious, appreciate all your help with this.

Hello Christian... Here are the logs and I hope we can work through this without the duplicator package. If we reach a dead end I will need to set up a special server environment for beta testing as I have to keep things separate for security reasons.
Did as you asked and I also created a new post. Further I have once again included all code so you have everything in front of you. There are a couple screenshots and you will see that there is also an error at the top of the post just below the title area.
