Adding <link rel="prev" etc

Has anyone been successful in adding <link rel="prev and "next" tags in their threads? I see most current software is doing this regardless of physical pagination.

I try it with the

Code:

<if condition="$show['next']"><link rel="next" href="$address$address2&amp;page=$nextpage</if>

<if condition="$show['prev']"><link rel="prev" href="$address$address2<if condition="$prevpage != 1">&amp;page=$prevpage</if></if>

but the hook is not active in the headinclude

Yeah, the problem is that the headinclude template is rendered before any of the page values are calculated. What you might be able to do is a str_replace on the $header variable at some later time. I'd have to know your exact version (and have that source available) to know what's around line 2405 of function.php. But maybe you can use a plugin at hook locaton pagenav_complete to add them, with code something like:

PHP Code:


		
			
global $headinclude;
if ($show['next'])
{
   $headinclude .= "<link rel=\"next\" href=\"{$address}{$address2}&amp;page={$nextpage}\"/>\n";
}
if ($show['prev'])
{
   $headinclude .= "<link rel=\"prev\" href=\"{$address}{$address2}&amp;page={$prevpage}\"/>\n";
}

Edit: (I replaced the above code - I copied the wrong version).

Works fine with this code:

Code:

 if ($pagenumber > 1)

        {

        global $headinclude;

                $prevpage = $pagenumber - 1;

                $prevnumbers = fetch_start_end_total_array($prevpage, $perpage, $results);

                $show['prev'] = true;

                $headinclude .= "<link rel=\"prev\" href=\"{$address}&amp;page={$prevpage}\">\n";

        }

        if ($pagenumber < $totalpages)

        {

        global $headinclude;

                $nextpage = $pagenumber + 1;

                $nextnumbers = fetch_start_end_total_array($nextpage, $perpage, $results);

                $show['next'] = true;

                $headinclude .= "<link rel=\"next\" href=\"{$address}&amp;page={$nextpage}\">\n";

        }

How would you do this without making changes to functions.php?

Is there a way to get the variables you need by using a plugin?

Been stumped on this one for a while.

Cheers,

So, is there a solution for adding prev / next in head?

PP - Sorry, the code above works fine - thank you

                $headinclude .= "<link rel=\"next\" href=\"{$address}&amp;page={$nextpage}\">\n";

        }

Have added this as a plugin - and pushing the links to page so that's bloody awesome.

Have been looking for a solution to this issue for a while now - and this is perfect. Had to tweak a few things to allow for my URL structure - but it's working perfectly now.

Also added in an if statement to cater for being on page 2 and not including a 'page=1' to the previous page.

THANK YOU VERY MUCH!!
