The rule is the following, and you cannot get around it I'm afraid: you have to apply for Schengen visa in the country of your first arrival into the Schengen zone (unless this is only for a connecting flight). Then, once you have it, it is valid for all Schengen signatory states. For example, if you are flying from Manila, via FRA, to Paris, and then you plan on going to Belgium, Holland, even back into Germany itself, then you have to apply for a Schengen visa with France.
