Re: etc_query: all things Textpattern

Version 8: now can also query databases, JSON objects and (even if it does not make much sense) serialized arrays.

Re: etc_query: all things Textpattern

Is there a way to do both numbered links and prev/next links in article_custom pagination? I’d like to use it for that, but thought I’d ask first.

You mean prev/next page? With one query it is tricky (in the current version), since we have to display some nodes twice, with different attributes. But with two queries it is possible (takes less than 0.005 extra seconds).

Suppose the navigation is driven by some url variable, say pgc. We firstly create the pagination list and store it in some variable:

<txp:variable name="pgc_list">
<txp:etc_query
  data='<txp:article_custom limit="999"><a href=''<txp:permlink />''><txp:title /></a></txp:article_custom>'
  query="a[position() mod 10 = 1]"
>
<a href="?pgc={#row}">{#row}</a>
</txp:etc_query>
</txp:variable>

Then in the article form put

<txp:if_individual_article>
<txp:variable name="pgc_list" />
<txp:else />
<txp:etc_query
  data='<txp:variable name="pgc_list" />'
  query="a[{?pgc|1|intval}]"
  globals="_GET"
  replace="preceding-sibling::a[position()=1]=Previous;following-sibling::a[position()=1]=Next"
>
{preceding-sibling::a[position()=1]}
<txp:variable name="custom_list" />
{following-sibling::a[position()=1]}
</txp:etc_query>
</txp:if_individual_article>

The article form can be completed with current page articles, enhanced with first/last links, restricted to showing at most n page links, and so on Please feel free to experiment, I will be glad to help .

Re: etc_query: all things Textpattern

Thank you, I’m trying that code out now. I’m going to try to troubleshoot, but I’m getting this error. Any advice is appreciated.

Re: etc_query: all things Textpattern

Oh my, I have a typo in the example, sorry, this should be <txp:variable name="pgc_list" />, and not <txp:variable name="custom_list" />. But this alone would not cause the problem.

Re: etc_query: all things Textpattern

Thanks for checking. I thought I was running PHP 5.3.8 but it was 5.2.17. So I’ve sent support a request, because I know it’s available. For the pagination, what I’m looking for is:

[Prev] 1 2 _3_ 4 5 6 7 [Next] [View All]

So “Next” would take you to page 4 if you were on page 3…etc. But the number links still work.

Re: etc_query: all things Textpattern

Yes, that’s what this part

<txp:etc_query
  data='<txp:variable name="pgc_list" />'
  query="a[{?pgc|1|intval}]"
  globals="_GET"
  replace="preceding-sibling::a[position()=1]=[Prev];following-sibling::a[position()=1]=[Next];@@class=current"
>
{preceding-sibling::a[position()=1]}
<txp:variable name="pgc_list" />
{following-sibling::a[position()=1]}
<a href="???">[View All]</a>
</txp:etc_query>

will do, additionally setting the class of the current page to “current”. But that’s all it will do, you will still have to display the articles of the current page using the pgc value in some way (offset?), which depends on your context.
