Hello,
I have set this script up to add paging to a search results page. Which on
the first page works fine. I calculates how many pages there should be
depending on the number of results returned from my search and how many
records I have set it to display per page. All great so far, HOWEVER.....
When you click the next link to see the next 10 results on the next page, it
just dumps the search details and pulls up all the records in the table! So
it finds 320 matching results, and then happily pages through them 10
records at a time, with both the next and prev links working!
I need to find a way of using this paging system in conjunction with the
search results, so if for example I search for "yellow" and I get 18
matching results with the first 10 being displayed on the first page, & I
then click next, I would like to see the last 8 results on the next page,
with the option to click 'prev' and see the previous 10 again. What actually
happens is that it shows me the first 10 matching results and says
displaying page 1 of 2, I click the 'next' link and it suddenly says showing
page 2 of 32 and starts listing all the records from the database starting
at record number 11 !
Please can anyone help me fix this?
Here is my current code:

================================================== =
It is basicly losing the search recordset details when I click 'next' or
