Handling sanitization of arrays submitted as params

[mwender]

When submitting a <select multple name="select_multiple_example[]"></select> with multiple values selected, running that value through sanitize_text_value() in HXWP_Render::sanitize_params() returns an empty value.

To get things working, I was able to write my own filter to handle arrays:

/**
 * Handles sanitizing arrays of params.
 *
 * @param      string $sanitized   The parameter after it has been run through sanitize_text_field().
 * @param      mixed  $unsanitized  The unsanitized value.
 *
 * @return     mixed  The sanitized paramter.
 */
function sanitize_array_params( $sanitized, $unsanitized ){
  if( is_array( $unsanitized ) ){
    foreach( $unsanitized as $key => $value ){
      $values[$key] = sanitize_text_field( $value );
    }
    $sanitized = $values;
  }

  return $sanitized;
}
add_filter( 'hxwp/sanitize_param_value', 'sanitize_array_params', 10, 2 );

However, I'm wondering if HXWP_Render::sanitize_params() should handle this natively since <select multiple> is pretty standard HTML?

Hi @mwender

Can you try v0.1.15, please?

v0.1.15 properly handles the scenario I outline above. Thanks @TCattd!
