How to correct this error Input Validation Not Performed

[Rno]

Hello,
How can I solve this issue: (not harming at least)
14/05/2020 12:48:49 - CMDPHP Input Validation Not Performed for 'page' Backtrace: (/plugins/ciscotools/ciscotools_tab.php[63]:ciscotools_displaybackup(), /plugins/ciscotools/display_backup.php[30]:get_request_var(), /lib/html_utility.php[369]:html_log_input_error(), /lib/html_validate.php[44]:cacti_debug_backtrace())

it's when I do a call to this:
input_validate_input_number(get_request_var("page"));

When I display a page of value!

If the value is numeric, then simply get the variable using this function

$page = get_filter_request_var('page');

There are several 'FILTERS' that you can pass as secondary and tertiary options to the function, but the default is VALIDATE_INT. Once you have called that once, the remainder of the calls on that page can be made using 'get_request_var() function since the variable has already been validated and set in the $CACTI super global for tracking request variables.

Thanks for the answer, I did find those options, so I was able to solve this warning message,
