Re: how to make two condation for if statement (if or)

<txp:if_article_list>
<txp:if_category name="news" limit="10">
<article>
<h2><txp:permlink><txp:title /></txp:permlink></h2>
<txp:excerpt />
</article>
<txp:else />
<txp:hide> this is still an article list but not in the news category - other tags</txp:hide>
</txp:if_category>
<txp:else /> <txp:hide>you are now on individual article</txp:hide>
<txp:if_article_category name="news">
<h1><txp:title /></h1>
<txp:body />
<txp:else /><txp:hide>you are on an individual article which is not in the news category</txp:hide>
</txp:if_article_category name="news">
</txp:if_article_list>

the above is untested but you may make your life easier if you use sections

<txp:if_article_list>
<txp:hide>you can have a specific template for the news section</txp:hide>
<txp:else />
<txp:hide>you are on an individual article page</txp:hide>
</txp:article_list>

there is no <txp:or /> tag. In order not to have to repeat code you could use a form

<txp:if_article_category name="news">
<txp:hide>you are in an individual article which is in the news category</txp:hide>
<txp:else />
<txp:if_category name="news">
<txp:hide>you are in the news article list category</txp:hide>
<txp:output_form form="newslist" />
</txp:if_category>
</txp:if_article_category>

Re: how to make two condation for if statement (if or)

If you’re testing OR cases for similar/the same tag, there’s smd_if and smd_multi_choice but in your case for two different cases, I’d probably do it this way without plugins:

<!-- set a variable default state -->
<txp:variable name="show_news_widget">no</txp:variable>

<!-- test condition one and change state if met -->
<txp:if_article_category name="news">
  <txp:variable name="show_news_widget">yes</txp:variable>
</txp:if_article_category>

<!-- test condition two and change state if met -->
<txp:if_category name="news">
  <txp:variable name="show_news_widget">yes</txp:variable>
</txp:if_category>

<!-- and then where you want your output -->
<txp:if_variable name="show_news_widget" value="yes">
  <txp:output_form name="news_widget" />
</txp:if_variable>

Interleave the conditions differently to achieve AND states. If you have a large site with modular components, you might want to put the if_variable statement directly in your output_form (although it may cost you extra db queries).

EDIT: In your particular case, as if_category and if_article_category cannot occur together (mutually exclusive contexts), you could also simply use the output_form directly in the if_category / if_article_category statements and do without the variable. Only one will ever apply depending on whether you’re on an article list or individual article page.
