That's a good idea. Meantime, I tried opening a new session and creating the variable $_session['offset'], which seems to work.
 
Thanks for your help.

One possibility: you could set the offset as an invisible field in your form.  Then after them form submission, when PHP gets the POST data, you can set the new offset field as the previously submitted offset plus one.  Know what I mean?


Best,

JS

I use a form page, with <form method= GET and an <input type = submit to activate the query, sending the first 10 hits to a table on a separate results page. However, on the results page I would like to add a button (type=submit or type=button) that would retrieve the next set of 10 records. On the results page, I set the $limit variable to 10 and this remains fixed, because I only want 10 records at a time.  I set the $offset variable to 0 for the first set of results and try to increment it  by 10 for the next set ($offset +=10;). However, as I understand html, once the results page is rendered, the $offset variable dies, so it cannot be incremented.
