PHP 7 compatibility

[fredbliss]

Are there plans in the works to ensure that isotope (isotope_rules, in this case) is php 7 compatible?

As an example of where this becomes a problem, please refer to https://github.com/isotope/core/blob/master/system/modules/isotope_rules/library/Isotope/Model/Rule.php#L283

mysql_real_escape_string() is used, but is deprecated in php 7. Is it even necessary to use that since the final mysql statement goes through Database->prepare() function?

It's supposed to be compatible, but that sure is a bug I need to fix.
