Custom Next/Previous links

I have a nice Textpattern site that I made recently for my personal Portfolio.
http://shrimpdesign.com

I made custom fields for 4 images URLs for each portfolio item, so that there are 4 different views of that portfolio piece.

I want to make a Previous/Next links that grabs a custom field from the previous and next portfolio items when viewing a single item. Because I want to have a graphical representation of the next and previous item, I’d rather have a little preview than just the title.

I tried using an <txp:older> tag with an <txp:article> inside of it, but I think it doesn’t work on the invididual page, and <txp:link_to_prev> only works with <txp:prev_title />.

Are there any workarounds?

Re: Custom Next/Previous links

You’ll need to make two more custom tags. The globals you are interested in are $prev_id and $next_id.

Re: Custom Next/Previous links

Sorry, I meant custom fields. I made custom fields for the images.

But it looks like I have to make my own plug-in, is that right? Using $prev_id and $next_id?
I guess I’ll look at textbook for info about making plug-ins.

Re: Custom Next/Previous links

Or wait, maybe I could do it with the handy tip at focusontheclouds ?

Just use <txp:php> and access the globals to get the next_id’s custom_field? Is that possible?

Yes, it’s possible. Either way does mean creafting a little more PHP than that, though.

Re: Custom Next/Previous links

I figured it out.

<ul>
<txp:php>
global $pretext, $next_id;
$next_custom_1 = safe_field('custom_1', 'textpattern', "ID='".$GLOBALS['next_id']."' limit 1");

echo "<li class=\"thumb-next\"><span style=\"background: url(" . $next_custom_1 . ") center center no-repeat\"><txp:link_to_next>next</txp:link_to_next></span></li>";

</txp:php>

<txp:php>
global $pretext, $prev_id;
$prev_custom_1 = safe_field('custom_1', 'textpattern', "ID='".$GLOBALS['prev_id']."' limit 1");

echo "<li class=\"thumb-prev\"><span style=\"background: url(" . $prev_custom_1 . ") center center no-repeat\"><txp:link_to_prev>previous</txp:link_to_prev></span></li>";

</txp:php>
</ul>
