isloop Element
Create loops for flow control.
- (items = item_object ) | (iterator = iter_object)
Allowed data type: expression.
You must include one of the following but not both:
-
items = item_object
item_object
is an expression that returns an object to iterate over. Attributes iterator and items can be used interchangeably. -
iterator = iter_object
iter_object
is an expression that returns an object to iterate over. Attributes iterator and items can be used interchangeably.
items
is preferred.-
items = item_object
- (alias = alias_name) | (var = var_name)
Name of the variable referencing the object in the iterable collection referenced in the current iteration.
You must include one of the following but not both:
-
alias = alias_name :
alias_name
is the name of a variable referencing the object in the iterable collection referenced in the current iteration. -
var = var_name :
var_name
is the name of a variable referencing the object in the iterable collection referenced in the current iteration.
var
is preferred.-
alias = alias_name :
- status = status_name
status_name
is the variable name referencing the loop status object. The loop status is used to query information such as the counter or whether it's the first item.If status is specified, a loop status object is assigned to the given variable name. Below are the properties of the loop status object:
Attribute Description count The number of iterations, starting with 1. index The current index into the set of items, while iterating. first True, if this is the first item while iterating (count == 1). last True, if this is the last item while iterating. odd True, if count is an odd value. even True, if count is an even value. - begin = start_index
Allowed data type: expression.
start_index
is an expression specifying a begin index for the loop. If the begin is greater than 0, the <isloop> skips the first x items and starts looping at the begin index. If begin is smaller than 0, 0 is used as the begin value.- end = stop_index
Allowed data type: expression.
stop_index
is an expression specifying an end index (inclusive). If end is smaller than begin, the<isloop>
is skipped.- step = increment_index
Allowed data type: expression.
increment_index
is an expression specifying the step used to increase the index. If step is smaller than one, one is used as the step value.
With <isloop>
you can loop through the elements of a specified iterator. As an example, you can list data like categories, products, shipping, and payment methods. <isloop>
statements can be nested in one another.
- Use
<isbreak>
to unconditionally terminate a loop. - Use
<isnext>
to jump forward in a loop
See isbreak and <isnext for more information.
