Search Page

Anon

I have a form with about 50 different elements to it, which ends up querying a database for search results. Right now, I have it so that if more than X number of results is displayed, an error is outputted. What I really want, however, is for say 50 results to be displayed, then have a link at the bottom that says "Next 50" results.

I have a lot of experience with doing things such as this with my database system, so that's not the problem. The problem is I need to link to the same page I'm at (with all the variables), and pass off 2 more variables to keep track of which results to display.

The question is, is there any way to compile a link to link to the page you're at, passing all variables on, without having to manually do it? Otherwise, the link for "Next 50" results would have to be like:
$PHP_SELF?a1=$a1&a2=$a2....&a50=$a50&index=50

Any thoughts?

I wrote a function a couple years ago to "page" through large results. Check it out at :

My problem isn't looping through results...what I need is some way to pass all variables from one page on to the other without explicity doing so in the link.

You might be able to get away with this using cookies. Reset the cookies at the top of every page. You would also then need to make sure that the cookies are deleted from each and every other page in your site.

Probably a more elegant way of doing this would be instead of a link, a button. Create a form with a bunch of hidden fields
<input type=hidden name=a1 value=$a1+50>... and a button for "next 50". Use a POST method, and you won't have a nasty URL.

Yeah I had thought of that, but the issue is the time involved to manually pass sooo many variables from page to page. Plus, if I ever modified the search page to include more fields, I'd have to modify the hidden fields as well. I thought perhaps there was a simple function (?) that would pass all variables on. Or, perhaps, do something with:

while (list ($key, $value) = each ($HTTP_POST_VARS)) {
// something here
}
