This thread is resolved. Here is a description of the problem and solution.
Problem: I have a Form that allows Users to select a parent post, and I would like to filter the list of parent post options. Then I would like to associate the two posts using custom code.
Solution: You can do this with a generic field, the cred_save_data API, and the toolset_connect_posts API. You must be sure to set the generic field to use the option "persist":1, like this:
[cred_generic_field field='custom-parent-field' type='select' class='' urlparam='']
{
"required":0,
"validate_format":0,
"default":[],
"persist":1,
"options":[ ...your explicit options here... ]
}
[/cred_generic_field]
You can access a generic field value in the $_POST superglobal during the cred_save_data callback. You won't have access to the new post's ID in the cred_before_save_data callback. The new post hasn't been created yet, so no id yet. You'll need both post IDs to connect them in a relationship, so you will use cred_save_data instead. If your field has the name "custom-parent-field" then your callback would look like this:
add_action('cred_save_data', 'cred_custom_callback_fn',10,2);
function cred_custom_callback_fn($post_id, $form_data)
{
$forms = array( 1234 );
// if a specific form
if (in_array($form_data['id'], $forms))
{
if (isset($_POST['custom-parent-field']))
{
$parent_id = $_POST['custom-parent-field'];
$parent = toolset_connect_posts( 'relationship_slug', $parent_id, $post_id );
// your other callback code continues here
}
}
}
Replace custom-parent-field with the name of your generic field. Replace 1234 with the ID of the Form, or a comma-separated list of Form IDs if you want to apply this same logic to more than one Form. Replace relationship_slug with the actual slug of this relationship.
