[Solved] Occurrences in a "yield" tag

Pat64 · 2026-02-26 06:41:08

Is it possible (and how) to verify different occurrences into a single conditional yield tag?

For compatibility with a previous short code, I need verify two occurrences into the new one.

The pipe sign seems not working:

<txp:if_yield name"old|new">
...do something wired...
</txp:if_yield>

🤔 💭

Do you need both occurrences to be true? If so try

<txp:if_yield name="old">
<txp:if_yield name="new">
...do something wired...
</txp:if_yield>
</txp:if_yield>

if only one occurrence is enough, you may need to call the yield twice.

<txp:if_yield name="old">
...do something wired...
</txp:if_yield>
<txp:if_yield name="new">
...do something wired...
</txp:if_yield>

Edited to add that there appears to be a typo in your snippet. If the pipe works, it should be

<txp:if_yield name="old|new">
...do something wired...
</txp:if_yield>

Thanks, Yiannis.

I’m familiar with using the conditional structure with the yield tag. I thought there was another way… something more magical. 🪄

I thought as much. Admittedly I was slightly surprised by the question:)

Feature request?

Hmm, the code does seem to suggest that the match and separator attributes are supported (though it’s not in the docs), but your situation seems to be different: it’s not the value you’re checking but the existence of either your old or your new yield attribute.

But maybe you can use a detour via a variable. Something like:

<!-- use a variable as a detection trigger -->
<txp:variable name="do_wired" trim>
    <txp:if_yield name="old">yes</txp:if_yield>
    <txp:if_yield name="new">yes</txp:if_yield>
</txp:variable>

<!-- check if the variable is set (= not empty) -->
<txp:if_variable name="do_wired" value="" not>
    we're wired …
</txp:if_variable>

Does that work for you?

Julian, I’m loving it!

That’s a typical Stef and Oleg’s style. A kind of magical, structural flavor! 🪄
