Branching out from the thread at https://toolset.com/forums/topic/creating-functions-for-inventory-management/page/2/#post-578835 to create the process below...
Creating a View of Users filtered by role, and using that View to populate the options for a generic field in your CRED form. Then you can capture the generic field values selected by the Owner and use those values to set the value of your actual custom field in the backend.
Dear Jon,
It requires custom codes, for example, you can try these:
1) Create a view "my-user-view" to list users, output the results as JSON format:
...
<wpv-loop>
[wpv-item index=1]{"value":"[wpv-user field="ID"]","label":"[wpv-user field="display_name"]"}
[wpv-item index=other],{"value":"[wpv-user field="ID"]","label":"[wpv-user field="display_name"]"}
</wpv-loop>
...
2) Create a CRED form with a generic field, use above view as the options of this generic field, like this:
[cred_generic_field field='my-generic-field' type='select' class='' urlparam='']
{
"required":0,
"validate_format":0,
"persist":1,
"default":[],
"options":[ [wpv-view name="my-user-view"] ]
}
[/cred_generic_field]
3) when user submit the CRED form, use action hook "cred_save_data" to save the value into database:

See similar thread:
https://toolset.com/forums/topic/allow-editor-to-select-appropriate-author-on-cred-edit-content-form/
Okay, I have Managed to get the values generated in the CRED form, though I'm struggling to get them saved to the database.
The following is the code I'm using...
[cred_generic_field field='vessel-authorised-reseller' type='checkboxes' class='' urlparam='']
{
"required":0,
"validate_format":0,
"default":[],
"options":[ [wpv-view name="authorised-resellers-dynamically-generated-for-cred"] ]
}
[/cred_generic_field]
add_action('cred_save_data', 'save_vessel_authorised_resellers',10,2);
function save_vessel_authorised_resellers($post_id, $form_data)
{
// if a specific form
if ($form_data['id']==193)
{
if (isset($_POST['vessel-authorised-reseller']))
{
// add it to saved post meta
add_post_meta($post_id, '__vessel-authorised-reseller', $_POST['vessel-authorised-reseller'], true);
}
}
}
The slug on the custom field (Single Line) created on the Vessel CPT is vessel-authorised-reseller
Can you advise on what may be the issue?
Also, if I'm to filter views conditionally based on these user IDs, is Single Line format best?
Ok, I have now got this to save through the forms, though existing values do not pre-populate in the Edit form.
Can you advise on how to show existing selections in the edit post CRED form?
The code I am using is as below...
add_action('cred_save_data', 'edit_vessel_save_authorised_reseller',10,2);
function edit_vessel_save_authorised_reseller($post_id, $form_data)
{
// if a specific form
if ($form_data['id']==208)
{
$vals= isset( $_POST["vessel-authorised-reseller"] ) ? $_POST["vessel-authorised-reseller"] : array();
foreach($vals as $val) {
add_post_meta($post_id, 'wpcf-vessel-authorised-reseller', $val, false);
}
}
}
You can setup the default value of as attribute "default", for example:
[cred_generic_field field='vessel-authorised-reseller' type='checkboxes' class='' urlparam='']
{
"required":0,
"validate_format":0,
"default":["a","c"],
"options":[
{"value":"a","label":"a"},
{"value":"b","label":"b"},
{"value":"c","label":"c"}
]
}
[/cred_generic_field]
Above generic field will be able to output a checkboxes fields with options "a", "b", "c", and setup option "a" and "c" as checked.
In your case, you will need to create another shortcode to get the field "__vessel-authorised-reseller" value from database
https://developer.wordpress.org/reference/functions/get_post_meta/
and output them into attribute "default"
https://developer.wordpress.org/reference/functions/add_shortcode/
Unfortunately this code is a little beyond me at the moment, is it possible you could provide an example for accessing and outputting the checkbox field values to the CRED form?
Here is a workaround,
1) Create a content template "test", with below codes:
[wpv-post-field name="wpcf-vessel-authorised-reseller" separator='", "']
2) Modify the CRED form, edit the codes from:
[cred_generic_field field='vessel-authorised-reseller' type='checkboxes' class='' urlparam='']
{
...
To:
[cred_generic_field field='vessel-authorised-reseller' type='checkboxes' class='' urlparam='']
{
"default":["[wpv-post-body view_template="test"]"],
...
And test again.
Looks like it's working, thanks!
