form validation is_unique using array

I don't think it can be used with an array, but maybe you can use a for loop with the check() function (https://codeigniter.com/user_guide/libra...te-1-value)

Something like this:

PHP Code:

foreach ($barcodes as $barcode)
{
    if ( ! $validation->check($barcode, 'is_unique[...todo add your table and field name...]'))
    {
        // Not unique
    }
}
