## Code

```php
$wpide_cf7_once_forms   = array(); // Form IDs, e.g. array( 123 ).
$wpide_cf7_once_message = 'You have already submitted this form. Thank you!';

add_action( 'wpcf7_mail_sent', function ( $contact_form ) use ( $wpide_cf7_once_forms ) {
    if ( is_user_logged_in() && in_array( (int) $contact_form->id(), array_map( 'intval', $wpide_cf7_once_forms ), true ) ) {
        update_user_meta( get_current_user_id(), '_wpide_cf7_done_' . (int) $contact_form->id(), time() );
    }
} );

add_filter( 'wpcf7_spam', function ( $spam ) use ( $wpide_cf7_once_forms ) {
    $form = function_exists( 'wpcf7_get_current_contact_form' ) ? wpcf7_get_current_contact_form() : null;

    if ( $form && is_user_logged_in() && in_array( (int) $form->id(), array_map( 'intval', $wpide_cf7_once_forms ), true ) && get_user_meta( get_current_user_id(), '_wpide_cf7_done_' . (int) $form->id(), true ) ) {
        return true;
    }

    return $spam;
}, 40 );

add_filter( 'do_shortcode_tag', function ( $output, $tag, $attr ) use ( $wpide_cf7_once_forms, $wpide_cf7_once_message ) {
    if ( 'contact-form-7' !== $tag || empty( $attr['id'] ) || ! is_user_logged_in() || ! function_exists( 'wpcf7_contact_form' ) ) {
        return $output;
    }

    $form = wpcf7_contact_form( $attr['id'] );
    $id   = $form ? (int) $form->id() : 0;

    if ( in_array( $id, array_map( 'intval', $wpide_cf7_once_forms ), true ) && get_user_meta( get_current_user_id(), '_wpide_cf7_done_' . $id, true ) ) {
        return '<p class="wpide-form-closed" role="status">' . esc_html( $wpide_cf7_once_message ) . '</p>';
    }

    return $output;
}, 10, 3 );
```

## Notes

List the form IDs at the top and combine with CF7's "subscribers_only: true" additional setting so only logged-in users can use the form.
