Link to A List of Articles Based on Custom Field

progre55 · 2011-08-16 03:56:31

This one is so simple, I cannot believe I am asking, but how can I create a link so that it will pull up a list of all articles with the same custom field —- I am not asking how you display a list which I know —-

Install adi_gps, make a link like this in your template or form:

<a href="<txp:site_url />?foo=bar">All articles with custom field Foo set to "Bar"</a>

Then wherever you want the articles to appear:

<txp:adi_gps name="foo" quiet="1" />
<txp:if_variable name="foo">
  <txp:article_custom foo='<txp:adi_gps name="foo" />' status="live">
    <h3><txp:permlink><txp:title /></txp:permlink></h3>
  </txp:article_custom>
</txp:if_variable>

That should do it…

Thank, maruchan. I will test out and let you know.

maruchan:

The first part is self explanatory — a little confused on the second part “wherever you want the articles to appear: <place this code>” — how does it know which template to use or where to go when the link is selected?

I tried placing it sin several locations with no success —-

So if your link url is example.com?foo=bar then you want that code in your default template. If your url is example.com/section-one?foo=bar then you want to put that code in the template that section-one uses (as long as you are using Textpattern’s clean URLs).

Or to put it another way, if this code needs to go in a certain section’s page template, make sure that you are adding ?foo=bar to a URL that contains that section’s name.

Here’s the code above but with a bit more error checking:

<txp:adi_gps name="foo" />
<txp:if_variable name="foo">
  <txp:article_custom foo='<txp:adi_gps name="foo" />' status="live">
    <h3><txp:permlink><txp:title /></txp:permlink></h3>
  </txp:article_custom>
<txp:else />
  <p>The variable has not been set. Please check your URL.</p>
</txp:if_variable>

BTW remember: No spaces or dashes (-) in custom field names or values. letters, numbers, underscores only.

Success … but …

I used this:

<a href="<txp:site_url />?Country=USA">All articles with custom field Country set to "USA"</a>

<txp:adi_gps name="Country" />
<txp:if_variable name="Country">
  <txp:article_custom Country='<txp:adi_gps name="Country" />' status="live" limit=50>
    <h3><txp:permlink><txp:title /></txp:permlink></h3>
  </txp:article_custom>
<txp:else />
  <p>The variable has not been set. Please check your URL.</p>
</txp:if_variable>

The above returned the articles as expected — which is a good thing …

Now, what I am trying to figure out is how I can get it to return information for custom fields that have spaces and data that has spaces.

I am using glz_custom_fields This allows me to create names that have spaces. It would be very difficult because of the state of project to go back and have to change all the custom fields.

Also, as an example,I have a field like Author — in this field it has first & last name (with space) — I was unable to get a return using that field —-

Any suggestions./guidance would be appreciated —-

No idea. You might want to start a new topic on using spaces in custom fields, and explain your authors example.

You can use bot_cf_titles to rename CF titles. But for values…no idea.

The space, when put in a url variable, may be encoded or dropped. I’d bet a tag trace from the results page would help solve the problem.

I never used adi_gps so I cannot comment but from the code above, i cannot see where the variable has been declared.

what about

<txp:variable name="hascountry" value='<txp:custom_field name="Country" />' />
<txp:if_variable name="hascountry" value="">
  <p>The variable has not been set. Please check your URL.</p>
<txp:else />
  <txp:article_custom Country='<txp:custom_field name="country" />' status="live" limit=50>
    <h3><txp:permlink><txp:title /></txp:permlink></h3>
  </txp:article_custom>
</txp:if_variable>

Yiannis, the nice thing about adi_gps is that it stores the requested url value in a txp:variable for you, which is why it is not declared.

Like Marc already mentioned, I see no way around custom_field names with spaces, or those that collide with other attributes used with txp:article_custom. txp:article_custom will regard the individual worlds of the custom field name as separate attributes, and probably also complain that they do not exist or are missing a value.

I’ve not tested it but I imagine that txp:article could accept values encoded as “Dominican%20Republic” (or that one could search and replace these easily before inserting them as an attribute-value in txp:article_custom).
