Logical and comparison operators
Liquid has access to many logical and comparison operators. You can use operators to create logic with control flow tags.
||does not equal|
||greater than or equal to|
||less than or equal to|
||condition A or condition B|
||condition A and condition B|
You can do multiple comparisons in a tag using the
contains checks for the presence of a substring in a string.
contains can also check for the presence of a string in an array of strings.
contains can only search strings. You cannot use it to check for an object in an array of objects.
Order of operations
In tags with more than one
or operator, operators are checked in order from right to left. You cannot change the order of operations using parentheses — parentheses are invalid characters in Liquid and will prevent your tags from working.
