Thank you for waiting and I apologize for the delay in getting back on this.
During testing and research, I couldn't find any built-in function or option to change the behaviour of the post-relationship selection field.
To have a regular select field, which shows all parent "EHRs" posts, you can follow these steps, as a workaround:
1. You'll need to register a custom shortcode, which can get the list of all available parent "EHRs" posts and create a custom regular select field, which includes only those posts as options, which are not already connected:
add_shortcode('create_shadow_parent_field', 'create_shadow_parent_field_func');
function create_shadow_parent_field_func() {
$parent_post_slug = 'ehr';
$relationship_slug = 'ehr-relationship';
$current_post = do_shortcode('[wpv-post-id]');
// get parent posts which are already connected
$get_results = toolset_get_related_posts($current_post, $relationship_slug, 'child', 9999, 0, array(), 'post_id', 'parent');
// get all the parent posts
$args = array(
'post_type' => $parent_post_slug,
'posts_per_page' => -1,
'post_status' => 'publish',
);
$posts_array = get_posts( $args );
// create a custom select field from the available parent posts, which are not already connected
ob_start();
if(!empty($posts_array)) {
echo '<select id="shadow_parent_selector" name="shadow_parent_selector"><option value="">-select-</option>';
foreach ($posts_array as $result) {
if(!in_array($result->ID, $get_results)) {
echo '<option value="'.$result->ID.'">'.$result->post_title.'</option>';
}
};
echo '</select>';
}
return ob_get_clean();
}
The above code snippet can be included through either Toolset's custom code feature ( ref: https://toolset.com/documentation/adding-custom-code/using-toolset-to-add-custom-code/ ) or through the active theme's "functions.php" file.
2. Next, in your relationship form, you can hide ( but not remove ) the actual parent post field added through the "cred-relationship-role" shortcode and include this custom select field, by adding this new shortcode [create_shadow_parent_field].
3. And in the form's JS editor, you'll include this script that will detect selection changes in this custom select field and update them in the hidden parent selection field:
jQuery( document ).ready(function() {
jQuery('select#shadow_parent_selector').on('change', function() {
var selectVal = this.value;
var selectText = jQuery(this).find("option:selected").text();
if( selectVal > 0) {
jQuery('#cred_association_ehr-relationship_parent').find('option').remove();
jQuery('#cred_association_ehr-relationship_parent').append(jQuery('<option>', { value: selectVal, text: selectText }));
}
else
{
jQuery('#cred_association_ehr-relationship_parent').find('option').remove();
}
});
});
As a result, the user will see the regular select field which shows all options at once, but, the selection will be updated in the actual autocomplete field too.
I hope this helps and please let me know if you need any further assistance around this.
