#XMLMIND NEXT PREVIOUS LINKS ARCHIVE#

One approach might be to calculate next/previous from each archive page and pass that in as a query string. Wanting that to change based on archive is tricky though since the archives are all about showing lists and link to the same document regardless of where the link originated. IDocument newer = (older != null || newer != (newer != null) For example, the following adds next and previous buttons to every post from inside the _post-footer.cshtml file (just for illustration though since the order isn't well sorted here, though I guess you could sort Inputs before getting older = (Document) The trick is to call the IEnumerable.GetNext(currentDocument) from the right collection. To address this, I created extensions on IEnumerable to get things like next/previous. That creates a ton of confusion because you end up with next/previous values that seem like they're correct but the document they point to is missing some metadata you think it should have, or doesn't have rendered content, etc. So at whatever stage you 'lock in' the next/previous metadata, if the set of documents are cloned after that, the Next metadata would still reference the original pre-cloned document. The challenge with next/previous traversal is that the documents can be cloned along the way (and often are). There might already be some support here to help you. The archive document has to provide some property that will give the next and previous docs.Īll said, my preference is to use what's there already.īeta Was this translation helpful? Give feedback. If not from an archive, I can default to the main Index or not display any links at all. The post must 'know' what archive it was linked from. If I need to solve it myself, it seems to me that I need to deal with two distinct problems:

But before digging into it I'd like to make sure there isn't something existing I can hook into. Thinking about this, I've come to the conclusion that I need to have some sort of properties set on the originating list itself. So, if we came from the main Index page, we'd get the next pst on that list, if we came from a tag we'd get the next item from that archive. Further, the ideal solution would give a different value for next and previous according to the particular archive from which we arrived at the post. (This article first appeared with an issue of the Possibilities newsletter.I'd like to modify _posts.cshtml so that each post (IsPost: true) displays links for the next and previous post.Įxisting Next and Previous properties of the document relate to pagination, so they are no help and are null anyway. Then, when the example has been modified to your satisfaction, publish the result on each web page that is to sport the 'next' and 'previous' links.

#XMLMIND NEXT PREVIOUS LINKS CODE#

The above four sections were extracted from the complete example code at the beginning of The Web Pages section. If you wish to publish the '▶' symbol, like at the live example, then specify ▶ for the link. Next > may be replaced with any combination of other text, image, and/or symbols for the link the site user is to tap for reading the next page. The location is specified relative to document root, not by URL. Replace /php/PreviousNext.php with the location of PreviousNext.php that you installed on your server. Here is the first section, the one line at the top of the complete example code, above. Following this complete example code, each of the four sections will be addressed separately. This complete example code is provided for an overall view. The code to do it is inserted into the web page where the links are to show up.īelow is complete example code.

#XMLMIND NEXT PREVIOUS LINKS HOW TO#

This section describes how to publish the 'next' and 'previous' links. Make a note of it's location because the PHP script's location will need to be specified on the web pages. When customization is finished, upload PreviousNext.php to your domain's server. If you want both (1) the 'next' link to disappear when the page being viewed is at the end of the list and (2) the 'previous' link to disappear when the page being viewed is at the beginning of the list, then replace false with one of the following:

The line tells the PHP script what to do when it is at the end or the beginning of the list.

Note that all URLs must be for the same domain as the web page with the 'next' / 'previous' links. Specify either the URL (begins with protocol or or the URI (protocol and domain name removed), one web page per line. The first is the list of web page URLs that the 'next' and 'previous' links will link to. Save it as PreviousNext.php or other *.php file name.

Then, update the pages that will have the 'next' and 'previous' links.
