Ok, now we see the Form produces an error (Form Type and post type do not match).
This is because if not passing a precise Post ID to edit the Form will try to edit the Current post and since it's a page, it throws the error.
Hence, in the Form ShortCode now you need to pass the Post to edit.
This is done with the GUI when inserting the ShortCode you choose "Another post" and in there simply select any of the posts offered, and then replace the Post ID it generates in the ShortCode with [wpv-search-term param="post_ids"].
This part ensures, that the Form Edits the one post passed in the URL parameters.
Note, I needed to edit the code a bit in the view - to make it work with the current setup.
Note also - yes, we pass MANY ID's to the post_ids parameter but the Form will accept only one, and since [wpv-search-term param="post_ids"] will return the last instance only, it will use that ID as the one to edit.
But it does not matter, because we will intercept this action and with Custom Code, propagate it to all Posts with ID's as set in the URL parameter.
The full shortcode is:
[cred_form form='update-selected-delegate' post='[wpv-search-term param="post_ids"]']
The View Code to generate the URL parameter was slightly edited:
<input type="checkbox" name="post_ids" value="[wpv-post-id]">
Now, when you head to hidden link, choose a few options, it will lead to something like hidden link
The Form will appear with the LAST of these Posts (RFG with ID 42813) prefilled in the form, ready to edit.
Now, we edit this and press submit, it will edit ONLY that one post, so we add a Custom Code, to propagate these changes to all the posts of all Post ID argument.
The code uses WordPress Logic (update_post_meta() in this example, on one single line field), and hooks to cred_save_data().

https://codex.wordpress.org/Function_Reference/update_post_meta
We also create a Custom ShortCode, which we put in the Form (in an HTML block), it is used to save keep the URL parameters we passed to the page with the form.
So step by step, to complete this you have to:
1. Register a Custom ShortCode that gets the Query params:
function url_query(){
$return = '<input id="post_ids" name="post_ids" value="'.$_SERVER['QUERY_STRING'].'">';
return $return;
//gives us something like post_ids=9&post_ids=11&post_ids=6
}
add_shortcode('url-query','url_query');
Please study the code and functions used, it's important to understand them
2. Now display the new ShortCode [url-query] in the Form, in an HTML block, anywhere you want - you can wrap it in a DIV that makes it invisible with CSS For example)
This makes sure, the post_ids we pass in the URL, are IN the Form, as we this later for updating the posts.
3. Now hook your code, whichh gets the URL parameter values from the new ShortCode above, and updates all posts with that ID, with the value passed in the Form (field or whatever it is that will be edited).
This is an example that needs to be adapted to your case:
add_action('cred_save_data', 'my_save_data_action',10,2);
function my_save_data_action($post_id, $form_data)
{
// if a specific form
if ($form_data['id']==7)//Change to the Form ID you use here (it's 42847)
{
//get data to update with - you will need to change this to your custom field or fields, if you have many.
$data_to_update_with = $_POST['wpcf-testing-single'];
//get data from post_ids parameters in URL - no change should ne needed here unless the attribute changes (it is post_ids here)
$url_params = $_POST['post_ids'];
//remove & - we need this to later easily create an array of all post_ids passed
//note, it would be wise to check here if you actually HAVE some post_ids or not, but this is a refinement to be done later
$url_params = str_replace('&', '',$url_params);
//split into array - the post_ids are many, so we need to ahve them each on it's own
$url_params = explode('post_ids=',$url_params);
//At this point we have an array of Post ID's we want to edit, as passed in post_ids url arguments, in an array
//now we can update all the posts in that array!
foreach ($url_params as $post => $id) {
//update only if Post ID is not 0
if ($id != 0){
//update the field you need to update, in this case a single line Types field, with the data you got from the Form, see first lines of the code above
update_post_meta($id, 'wpcf-testing-single', $data_to_update_with)
}
}
}
}
4. Now that you have the code in place, you can try to check a few Posts in your view, iht "edit" so it calls the bulk edit list, in where you should then see the Post Form and you can make an edit to the field passed in the code.
Then you submit the form and it should update all fields of all posts as passed in the View originally.
Note, the code above considers only ONE field. You would need to extend the code if it should address other fields too.
Please let me know if you need help at any point of this.
