iteration
iteration is used to display the current loop iteration.
iteration 用于显示循环的次数.
NOTE: This is not affected by the section properties start, step and max, unlike the index property. Iteration also starts with 1 instead of 0 like index. rownum is an alias to iteration, they work identical.
注意：iteration 不像index属性受start、step和max属性的影响，该值总是从1开始(index是从0开始的).rownum 是iteration的别名，两者等同.
Example 7-24. section property iteration
例 7-24. section 的 iteration 属性演示
{section name=customer loop=$custid start=5 step=2} current loop iteration: {$smarty.section.customer.iteration}
{$smarty.section.customer.index} id: {$custid[customer]}
{* FYI, $custid[customer.index] and $custid[customer] are identical in meaning *} {if $custid[customer.index_next] ne $custid[customer.index]} The customer id will change
{/if} {/section} OUTPUT: current loop iteration: 1 5 id: 1000
The customer id will change
current loop iteration: 2 7 id: 1001
The customer id will change
current loop iteration: 3 9 id: 1002
The customer id will change
