Hello @tgilber007 !
I hope you’re doing great today!
Forminator doesn’t have an option for this built in yet, but if you’re using a form, you can use this snippet to limit the submissions to once per user:
<?php
add_filter(
'forminator_render_form_markup',
function( $html, $form_fields, $form_type, $form_settings, $form_design, $render_id ) {
if ( is_user_logged_in() ) {
global $wpdb;
$user_id_field_name = 'hidden-1';
$user_id = get_current_user_id();
$message = __( 'You can submit this form only once' );
$user_entries = $wpdb->get_var(
$wpdb->prepare(
"SELECT COUNT(e.entry_id) FROM {$wpdb->prefix}frmt_form_entry as e
INNER JOIN {$wpdb->prefix}frmt_form_entry_meta as m ON e.entry_id=m.entry_id
WHERE m.meta_key=%s AND m.meta_value=%d
LIMIT 1",
$user_id_field_name,
$user_id
)
);
if ( ! empty( $user_entries ) || 0 < $user_entries ) {
return $message;
}
}
return $html;
},
10,
6
);
To install the script, please copy the code to a .php file and place it in wp-content/mu-plugins directory after adjusting.
To adjust:
Your form will need to have a Hidden field added with default value set to “User ID”. If the field is named hidden-1, no adjustments are needed.
If the field has a different name, you’ll need to change the line:
$user_id_field_name = 'hidden-1';
To match the identifier of the field.
Then the form will be checking if there’s already a submission for the same form from the current user and will prevent the form from being sent.
Regarding the part about the myCred plugin – this will require custom coding depending on how that plugin accepts points. From the Forminator side you can use the Forminator API which has documentation available here: https://wpmudev.com/docs/api-plugin-development/forminator-api-docs/
This will certainly require custom coding to connect the two plugins together – very likely hiring a developer will be necessary in this case to review the myCred documentation as well.
Best regards,
Pawel
