Is there a way I can do this with txp?

colak · 2008-01-31 09:26:32

Is there a way of comparing the content of custom fields and according to that, to output a list of ‘related articles’?

To be more precise: Currently we use the search function to list the articles by author¹ using "author name":http://neme.org/main/?q=by+author+name

I find this to be semantically wrong and what I am trying to achieve is the following 2 listings.

An automatically generated “related articles” listing on a per article page linking to the other texts we have by the same author
A listing² of all the authors, currently manually created and found on the about page.

¹ Note that by author I mean the article author and not the person with privileges in the db. The site only has 3 registered authors and the material is gathered through an online submission form.

² Not a site-map but more of an ‘author-map’ which when an author’s name is clicked a list of articles by that author is returned. That is, all articles which have the same name typed in a particular custom field.

I think this would go along the lines of the example for if_different from Textbook by using the custom field instead of the current article’s section.

Hi Wet,
thanks for your answer. That’s what i thought and started to do some work on it but I’m yet to produce any results.

This is where I’m at

I have a custom field called “sortauthor” and a form called “authorsmap” with this inside:

<dt><txp:if_different><txp:custom_field name="sortauthor"></txp:if_different></dt>
<dd><txp:if_custom_field name="sortauthor"><txp:custom_field name="sortauthor" /></txp:if_custom_field></dd>

I am calling the form in a page template using <txp:article_custom sort="sortauthor" form="authorsmap" />… I am yet to put the site in debug mode but currently I get nothing returned.

At first glance, this looks usable. A tag trace would definitely help.

Ok this kind of works but not the way I intend it

page template: <ul><txp:article_custom sort="custom_6" form="authorsmap" limit="999" /></ul>

form: authorsmap

<txp:if_custom_field name="sortauthor">
<txp:if_different>
<txp:custom_field name="sortauthor">
</txp:if_different>
<li><txp:permlink>
<txp:custom_field name="sortauthor"></txp:permlink></li>
</txp:if_custom_field>

current problems

<txp:custom_field name="sortauthor"> is not parsed so what i am getting is something like <li><a rel="bookmark" href="http://neme.org/main/57/millenium-museum-journal"> <txp:custom_field name="sortauthor"></a></li>
As per the behaviour, it outputs all articles which use that custom field whereas what I am looking for is a linked name pointing towards a list of articles by that name

I’m thinking of chs_if_urlvar and asy_wondertag here. I sort of tested it and it seems to work.

Form ‘authorsmap’:

<txp:if_custom_field name="sortauthor">
	<txp:if_different>
		<li><a href="/?a=<txp:custom_field name="sortauthor" />"><txp:custom_field name="sortauthor" /></a></li>
	</txp:if_different>
</txp:if_custom_field>

On the page:

<txp:chs_urlvar_default var="a">
	<ul><txp:article_custom limit="9999" form="authorsmap" sort="custom_6" /></ul>
</txp:chs_urlvar_default>

<txp:chs_urlvar_exists var="a">
	<txp:asy_wondertag><txp:chs_if_urlvar var="a" value="<txp:chs_urlvar_echo var="a" />"></txp:asy_wondertag>
   		<txp:asy_wondertag><txp:article_custom sortauthor="<txp:chs_urlvar_echo var="a" />" form="authorlist" /></txp:asy_wondertag>
	</txp:chs_if_urlvar>
</txp:chs_urlvar_exists>

A downside could be that you can’t set the limit exactly. It has to be a high number because it counts and searches all articles, not only the ones that match. I also don’t know what that means for performance.

colak,

your example includes unclosed <txp:custom_field name="sortauthor">, when it should be closed <txp:custom_field name="sortauthor" /> :)

Gocom… good catch. I always forget those:)

Els… I think that your suggestion might work. Will make time over the weekend to test it and i’ll be posting the results here.

thanks for all the help.
