Using and/or with if statements (conditionals) in the Liquid templating language

Just a quick thing here but a lot of times when I’m working on a Shopify theme and coding in the Liquid template language I forget the syntax to combine 2 if statements.

First, here is how you would write an if statement in Liquid.

{% template == 'index' %}
do something here...
{% endif %}

Now, if instead you want to check on whether 2 conditions are true, you could use the following syntax:

{% if template == 'index' and settings.show_image == 'yes' %}
do something here
{% endif %}

If you want to check whether just one of the conditions is true, then of course just change the and to or:

{% if template == 'index' or settings.show_image == 'yes' %}
do something here
{% endif %}

This syntax plus a whole lot of other Liquid syntax is documented on the Liquid page of the Shopify Wiki. I just wrote it down here to help myself remember it and maybe to save somebody else some time remembering or learning it later.
