[ZPT] Batching SQL results

[Kim Kaim]

Hello,

I'm hoping I'm just overlooking something really simple and someone can  
set me straight.

I've just set up my first MySQL queries.  The query is fine, the search  
page is fine, the results page displays the first page fine.  However,  
the next/previous results links do not appear to work.  I believe I  
have narrowed it down to an incomplete URL, but I'm not sure how to fix  
it.

An example of what I have written is...

<a tal:condition="previous"
        tal:attributes="href  
string:${request/URL0}?start:int=${previous/first}"
        href="previous_url">previous <span  
tal:replace="previous/length">20</span> results</a>

The link that this creates is . . .

http://www.uqu.uq.edu.au/medicalbookshop/bookshop/search_Report?start: 
int=21

But what it NEEDS to say is . . .

http://www.uqu.uq.edu.au/medicalbookshop/bookshop/search_Report? 
ISBN=&TITLE=&AUTHOR=smith&CATAGORY=&SUBMIT=Submit+Query&start:int=21

How can I get the URL to expand so that is contains the query part as  
well?

Thank you,
Kim
