linked custom_fields list

zoltandragon · 2008-02-24 12:35:14

This might sound crazy at first, but I am wondering whether it is possible to output a list based on a custom field in a way that you can click on the list items. E.g. I have a custom fields for “Producers,” and I have 10 different producers. What should I do to call the info stored in the custom fields in a way that users can click on the producer of their choice and that takes them to a list of articles related to that particular producer? (I hope I am making sense…)

Thanks for any hint in advance!

Sounds like a problem for a plugin, and I don’t know of any that would do this. How about making a “Producers” category, then assigning each producer a category that is a child of the “Producers” category? Then you could get the list by using <txp:category_list parent="Producers" />.

The problem is that the organization of the page has already used sections and categories for various (completely) different roles, and the producers cluster would only be a small part of information – excellent for custom fields that gathers a lot of tiny data alongside with it. It would also be great to have all the other custom field contents listed (names, etc.), so that it becomes a very useful and easy presentation for users who search for something (without actually filling in a search field – which is a problem when they don’t know the exact phrase…).

Anyway, I’ll give it a go and try to play arund with the idea, thank you!

It would be simple to make a plugin that returns a list of all distinct values in a custom field. The trick would be making each list item a link to an article list based on that custom field — maybe create a new section for this, that doesn’t contain any articles in itself, but has <txp:article_custom /> tags in the template to output lists based on custom fields. Sounds clunky, but might be possible.

i’ve achieved something similiar in the past by using the custom field value as url variable.
in the article form:

<a href="/whatever/?producer=<txp:custom_field name="producer" />">See all productions by <txp:custom_field name="producer" /></a>

and then, in the page template you can use

<txp:chs_urlvar_default var="producer">
<txp:article /> <!-- here you put the default rendering -->
</txp:chs_urlvar_default>
<txp:chs_urlvar_exists var="producer">
<h2>All productionsy by <txp:chs_urlvar_exists var="producer" /></h2>
<txp:asy_wondertag><txp:chh_article_custom producer="<txp:chs_urlvar_exists var="producer" />" /></txp:asy_wondertag>
</txp:chs_urlvar_exists>

you’d need chs_ifurlvar and chh_article_custom

EDIT: oh you want a list of producers as well. guess that could be achieved by using in a page template

<txp:article limit="999" form="producerList" />

and in producerList:

<txp:if_different>
<a href="/whatever/?producer=<txp:custom_field name="producer" />"><txp:custom_field name="producer" /></a>
</txp:if_different>

Wow! I’ll try this immediately :) Thanks ever so much!

zoltandragon · 2008-02-24 15:30:25

The link outputs this html:

<p><a href="/?producer=Ursa“>All products by Ursa</a></p>

Textile doesn’t like

<a href="/?producer=<txp:custom_field name="producer" />">All products by <txp:custom_field name="producer" /></a>

Is there a way to make it love it? :)

sthmtc · 2008-02-24 15:43:06

uhm, where did you put the link? in an article form or in the actual article itself?

zoltandragon · 2008-02-24 15:58:01

of course into the article itself… sorry… dohhh….

zoltandragon · 2008-02-24 16:21:59

Okay, remedied… :) But now the problem is that I’m using another word for “producer,” which has special characters… (i.e.: “Gyártó” – in Hungarian). Might that be a problem? Right now I’m getting errors like this:

The following tag caused an error: <txp:chh_article_custom Gyártó="<txp:chs_urlvar_exists var="Gyártó" /> -> Textpattern Notice: Unknown ...: id on line 605

zoltandragon · 2008-02-24 16:23:17

Oh, and for the producersList solution it doesn’t render anything… weird…

sthmtc · 2008-02-24 16:43:58

yeah i guess these special characters in the custom field name are problematic. can’t you rename it?

edit: same goes for the url variable. i bet you can’t use special characters there without running into problems. i’d strongly suggest renaming it, as it doesn’t appear anywhere except for the backend i think it shouldnt matter if you’d leave out the special chars.
