I recently worked on a project, which required me to use wordpress to create a blog. One of the objectives was to break the blogroll up into catagories using multiple templates and the custom query_posts() function. This in itself was fine, however I ran across a problem when I wanted to use Lester ‘GaMerZ’ Chan‘s wordpress WP-PageNavi plugin to paginate the posts over multiple pages. This post will talk you through how to resolve this issue and be able to use the WP-PageNavi plugin with any query_post() parameters and proper permalink structures.
Whats the problem!?
The problem comes when WP-PageNavi is used in conjunction with query_posts() and custom permalink structures. Bascially the plugin cannot determine which page the user is on, therefore it defaults to the first page every time the page loads.
Fixing without custom permalinks
If your blog is not using a custom permalink structure and you have opted for “ugly” URL’s you can quickly bypass this issue with the following code:
$page = $_GET['paged'];
query_posts('cat=1,2,3&paged='.$page);All we are doing here is assigning the page number that is passed as a GET parameter into a variable called $page. Then in the query_posts() function we use the assigned variable to dynamically draw out the correct page number and thus displaying the correct page.
Fixing it with a custom permalink structure
If your using a custom permalink structure you will inevitably run into the issue that there are no GET parameters being passed for the page number. Lets consider the following URL of a page on your blog:
In order to work out what page we are on we will need to strip off everything from this URL except for the page number, in this case 2. In order to achieve this I have modified a PHP funciton written by web master cheat sheet. Which looks like this:
function curPageURL() {
$pageURL = 'http';
//check what if its secure or not
if ($_SERVER["HTTPS"] == "on") {
$pageURL .= "s";
}
//add the protocol
$pageURL .= "://";
//check what port we are on
if ($_SERVER["SERVER_PORT"] != "80") {
$pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
} else {
$pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
}
//cut off everything on the URL except the last 3 characters
$urlEnd = substr($pageURL, -3);
//strip off the two forward shashes
$page = str_replace("/", "", $urlEnd);
//return just the number
return $page;
}The function curPageURL() basically gets the URL of the page you are on, then removes everything but the current page number and assigns it to a variable called $page ready for use in our query like so:
//add in the catagory and page number
query_posts('cat=7,8,12,13,15&paged='.curPageURL());As you can see the query is almost identical to beofore, only this time we call the function instead of the variable. Job done!

Thanks for offering this solution – it works great. I am using a custom permalink structure but rewrote your curPageURL using a regular expression match. It reduces the code to two lines. The regular expression is searching for any number of digits after “page/. This is what I came up with:
function curPageURL() {
preg_match(‘/page\/(?P\d+)/’, $_SERVER["REQUEST_URI"], $matches);
return $matches['page'];
}
Thanks again!

Looks like some of the code was stripped out. This part ‘/page\/(?P\d+)/’ should have a less than sign followed by “page” (no quotes) followed a greater than sign. This should come immediately after “?P”. So: (?P[less than sign]page[greater than sign]\d+) – of course you need to substitute [less than sign] and [greater than sign] with their appropriate character.

Instead of curPageURL() you can use get_query_var(‘paged’);

@merry, It depends on the construction of your theme, I would advise putting it in loop.php

You saved my life Philip Beel, thank yous so much.
Anyway, When I first put this code:
$page = $_GET['page'];
to my script, it didn’t work. Then I tried with this
$page = $_GET['paged'];
since the parameter passed is named that way, and it worked. Just in case someone having the some problem like I did.
Thanks again
