How do I sort posts with multiple pages

Question

I am using a drop-down to sort posts by title, meta_value, etc. However, the sorting feature only works on the first page. The second page displays the default order rather than continuing the order from page 1. I am using wp-pagenavi for pagination. Any ideas what would be causing this error?

Here's a link to the code:

Thanks so much.

Answer 1

You're initially submitting a POST request via a form with the sort parameters. When you click links to additional pages, you're just sending a GET request for the next page without those original POST vars, so they don't carry over to the additional pages and aren't picked up by your if(isset($_REQUEST['sort'])). Probably the simpler way to handle it is to pass the sort parameter as a query string appended to the URL, then check for that query string and append it to the URLs of the additional pages.

Answer 2

You are setting $paged after the if conditionals that use it.

// more uses of $paged that way ^^^^
else
        $order = array(
        'cat' => 30,
        'orderby' => 'title',
        'order' => 'ASC',
        'paged' => $paged
);

$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;

Put that $paged = line before those conditionals and I bet it makes a difference.
