I’d like some help with Tera language if and elseif statements

I’m not good at all with writing out Tera. What I’m trying to do is say:

If term.name = widgets

output this description

So far I have got this:

  {% if term.name | widgets %}
    <h2>Description</h2>
  {% endif %}
```

This doesn’t work, as in the description isn’t output for that particular term.

It would also be useful to know how to use an`elseif`.Any advice appreciated.

{% if price < 10 or always_show %}
   Price is {{ price }}.
{% elif price > 1000 and not rich %}
   That's expensive!
{% else %}
    N/A
{% endif %}

Thanks for this, but I am looking for something to do with the taxonomy and terms. Probably didn’t explain myself very well because I don’t know what I’m trying to explain. If a term name on a given page is ‘Widgets’ I need it to return a widgets’ description. If the term name happens to be ‘Wantons’ I need it to return a wantons’ description.

Does that make sense?

Maybe you want:

{% if page.taxonomies.categories %}
  {% if "Widgets" in page.taxonomies.categories %}
    <p>Description for Widgets goes here...</p>
  {% elif "Wantons" in page.taxonomies.categories %}
    <p>Description for Wantons goes here...</p>
  {% endif %}
{% endif %}

If you end up having many terms, writing dozens of elif statements in your template can get messy. You can instead store your term descriptions in config.toml under [extra.term_descriptions]:

[extra.term_descriptions]
widgets = "This is the description for widgets."
wantons = "This is the description for wantons."

Then in your template, retrieve it dynamically without needing any if / elif blocks:

{% if config.extra.term_descriptions[term.slug] %}
  <p>{{ config.extra.term_descriptions[term.slug] }}</p>
{% endif %}

Thanks, Colas. The dynamic method worked for me. The first method didn’t, despite me changing categories to tags.

Being a complete numpty when it comes to this type of thing, I really appreciate the effort it takes for someone in the know trying to explain things.

Thanks.

Ah Yes, it was “tags”, and it worked for me… but anyways the dynamic version is nicer :slight_smile:

% if page.taxonomies.tags %}
  {% if "Widgets" in page.taxonomies.tags %}
    <p>Description for Widgets goes here...</p>
  {% elif "Wantons" in page.taxonomies.tags %}
    <p>Description for Wantons goes here...</p>
  {% endif %}
{% endif %}

I would advise you to use AI, it is an invaluable tool to learn (or just cope with) new systems. Especially for these “How to?” questions.
