Problem: I have two custom fields in a Form, and I would like to only allow one of the fields to be filled in. I would like to set up some form validation that prevents form submission if a User fills in values for both fields.

Solution: There are two options in our system:
- Conditional Form Groups: You can use Conditional Form Groups to show or hide the "Submit" button based on the value of these fields. If both fields are not empty, then you can hide the submit button. This is "front-end" validation, meaning that the validation occurs before the form is submitted.
- Custom validation API: You can use custom code to validate form fields on the "back-end". If errors are detected, the form will reload and display your custom error messages. This requires PHP code.

Beyond that you may be able to use custom JavaScript to handle this type of DOM manipulation.

How to add hook for multiple CRED form IDs.

you should try to use following code where you can check multiple form IDs using in_array() function.

You can find proposed solution, in this case, with the following reply:

Problem: I would like to automatically assign a specific taxonomy term to posts created by a CRED Form.

Solution: Add the following code to your child theme's functions.php file:

add_action('cred_save_data', 'auto_cred_term_action',10,2);
function auto_cred_term_action($post_id, $form_data)
{
    // news posts
    if ($form_data['id']==123)
    {
   
            $tag = array( 149 ); // Taxonomy term ID
            $taxonomy="category"; // Taxonomy name
            wp_set_post_terms( $post_id, $tag, $taxonomy );
   
    }
}

Replace 123 with the numeric ID of the CRED form, then remove the taxonomy cred_field shortcode from the CRED form builder.
