add an input mask to an input in a Gravity Forms list field column

ListFieldMaskedInput

// enable input mask for form #95 list field #3 columns 1 and 3
add_filter('gform_register_init_scripts_95', 'enable_list_input_mask');
function enable_list_input_mask($form) {
    $field_id = "3"; //set field id here
    $col_id = array('1','3'); //set column id here
    $mask = "9999"; //define mask here, examples at http://www.gravityhelp.com/documentation/page/Input_Mask
    //that's it nothing more to configure 

    $c_sel = array();
    foreach($col_id as $c) {
        $c_sel[] = ".gfield_list_{$field_id}_cell{$c} input";
    }
    $c_sels = json_encode($c_sel);
    $im_script = "jQuery(sel.join()).mask('{$mask}');";
    $script = "var sel = {$c_sels}; {$im_script} jQuery('#field_{$form["id"]}_{$field_id}').on('click', '.add_list_item', function(){{$im_script}});";
    GFFormDisplay::add_init_script($form['id'], 'list_input_mask', GFFormDisplay::ON_PAGE_RENDER, $script);
    return $form;
}
add_action( 'gform_enqueue_scripts_95', 'list_masked_input_script', 10, 2 );
function list_masked_input_script( $form ) {
    wp_enqueue_script( 'gform_masked_input', array( 'jquery' ), false, true );
}

Thanks for this!

Hi,

I was wondering if you could post the code to add input mask to a particular field.

I am using the address field and want to add a mask to the zip/postal code field but there is no option there.

I have used this but doesn't seem to work. From the GF website

add_filter( 'gform_input_masks', 'add_mask' );
function add_mask( $masks ) {
$masks['Address Postal Code'] = 'A9A 9A9';
return $masks;
}

Any help would be appreciated.
Thanks.

Hello, I'm in the same boat as @ByteOutfitters. I have two list item fields and tried the same solution he did by separating out the two filters, but the input mask only applies to the first filter. Was there ever a solution for this?

Thanks!
