I´m passing get values (comma delimited) to an iframe to process customer selection... At the iframe an array of this values is created (split) for inside calculations and reports.
I´m actually using these array values to perform mysql queries on child that was already done by parent page... Is there a easy way to optimize it saving the extra query on child maybe passing the subvalues from parent using other inside-comma delimiter to be constructed as another array on child? Is explode and substring explode the best option? I´d like to keep passing single var to iframe.
