How to set a variable for a cached template in a custom page?

[bzcomputers]

I'm trying to use data from MYSQL to cache a template.

I know everything with the MYSQL database connection works fine, but I can't seem to get the syntax right for placing the variable within the globaltemplates array.


What I'm working with:

// pre-cache templates used by all actions
$globaltemplates = array('cruisecams_ports', 'cruisecams_ports_menu', 'adblock_cruisecams_sidebar', 'sociallinks');

I'm trying to replace 'cruisecams_ports' with the data from MYSQL stored in $portcamtemplate.


Currently I'm just getting this error "Fatal error: Call to undefined method dbPDO::query_first_slave()" anytime I try and place the variable in the array.

All other MYSQL data works fine in the rendered page it's just when I try to set a variable in the template array that the issue occurs.
