Control flow tags
Control flow tags create conditions that decide whether blocks of Liquid code get executed.
Executes a block of code only if a certain condition is met (that is, if the result is true
).
Like if
, but executes a block of code only if a certain condition is not met (that is, if the result is false
).
The above example is the same as:
else / elsif
Anchor link to section titled "else / elsif"Adds more conditions to an if
or unless
block.
case / when
Anchor link to section titled "case / when"Creates a switch statement to execute a particular block of code when a variable has a specified value. case
initializes the switch statement, and when
statements define the various conditions.
You can optionally add an else
statement at the end of the case to provide code to execute if none of the conditions are met.
Multiple conditions (and / or)
Anchor link to section titled "Multiple conditions (and / or)"You can use the and
and or
operators to include more than one condition in a control flow tag. and
and or
can be chained together to create complex conditionals. To learn about the order in which these operators are checked, refer to the Operators reference.
The and
operator lets you add additional conditions to a tag. A condition with an and
will only be true if both the left and the right side of the condition are true.
The or
operator lets you add additional conditions to a tag. A condition with an or
will be true if either the left or the right side of the condition is true.
