Fancy Loops

Ordinary loops simply repeat their body once for each article that matches the condition. For special effects, you can create loops with special behavior:

• Alternate styles for odd and even items, using {$ odd $} and {$ even $}. See Alternating Styles.
• Display alternative text when there are no items in the loop, using {$ else $}. See Alternate Text for Empty Loops.
• Display text between each item in a loop, using {$ between $}. See Text Between Items in Loops.
• Display text before and after the loop, but only if there are matching items, using {$ before $} and {$ after $}. SeeBefore and After in Loops.

The complete syntax is:

{$ forEach n var in (condition) sort-order $}
.... text which appears for each item ....
{$ between $}
.... text which appears between each two items ....
{$ odd $}
.... text which appears for every other item, including the first ....
{$ even $}
.... text which appears for every other item, starting with the second ....
{$ else $}
.... text which appears if there are no items matching condition ....
{$ before $}
.... text which appears before the loop, only if there are items matching condition ....
{$ after $}
.... text which appears after the loop, only if there are items matching condition ....
{$ next $}

Each of these sections is optional.
