Smarty - 手册 - 第8章 自定义函数 - {cycle}循环

{cycle}

{cycle} is used to alternate a set of values. This makes it easy to for example, alternate between two or more colors in a table, or cycle through an array of values.

{cycle} 用于在值集合中轮换。便于实现下述情况，在一个表格中交替输出两种或多种颜色，在值数组中循环。

Attribute Name	Type	Required	Default	Description
name	string	No	default	The name of the cycle
values	mixed	Yes	N/A	The values to cycle through, either a comma delimited list (see delimiter attribute), or an array of values
print	boolean	No	TRUE	Whether to print the value or not
advance	boolean	No	TRUE	Whether or not to advance to the next value
delimiter	string	No	,	The delimiter to use in the values attribute
assign	string	No	n/a	The template variable the output will be assigned to
reset	boolean	No	FALSE	The cycle will be set to the first value and not advanced

• You can {cycle} through more than one set of values in a template by supplying a name attribute. Give each {cycle} an unique name.

• You can force the current value not to print with the print attribute set to FALSE. This would be useful for silently skipping a value.

• The advance attribute is used to repeat a value. When set to FALSE, the next call to {cycle} will print the same value.

• If you supply the assign attribute, the output of the {cycle} function will be assigned to a template variable instead of being output to the template.

Example 8-5. {cycle} {/section} {section name=rows loop=$data} {$data[rows]} The above template would output: 1 2 3
