Adding a LEFT to ApexPages.currentPage().getParameters().get('oppId');

I have a visualforce page and controller, part us which grabs "oppid" from the url and inserts it as part of the record.

a.Opportunity__c = ApexPages.currentPage().getParameters().get('oppId');
This works fine, if I have a URL such as:

But sometimes, I get a URL such as:

I would like to strip off everything after oppid=(first 15 chars). I was thinking about using something like LEFT,15 to do it. I have yet to get the formating right. Any suggestions?

Not sure how this is happening by normal salesforce generated urls, you could try substring in apex i.e. 
if (oppId != null && oppId.length() > 15) {
            oppId = oppId.substring(0, 15);
