使用Smarty计算子数组中的总出现次数

Question

我有这个数组：

[attributes] => Array
(
[1] => Array
(
[id_attribute] => 1
[id_attribute_group] => 1
[name] => Rosso
[group] => Colore
[reference] => WD1012
[ean13] => 
[isbn] => 
[upc] => 
)
[9] => Array
(
[id_attribute] => 24236
[id_attribute_group] => 9
[name] => 31 x 86.5 cm.
[group] => Dimensioni Fiore 1
[reference] => WD1012
[ean13] => 
[isbn] => 
[upc] => 
)
[10] => Array
(
[id_attribute] => 24237
[id_attribute_group] => 10
[name] => 31 x 71.5 cm.
[group] => Dimensioni Fiore 2
[reference] => WD1012
[ean13] => 
[isbn] => 
[upc] => 
)
[11] => Array
(
[id_attribute] => 24238
[id_attribute_group] => 11
[name] => 32.5 x 88 cm.
[group] => Dimensioni Fiore 3
[reference] => WD1012
[ean13] => 
[isbn] => 
[upc] => 
)
)

我想计算[组]的值，同时搜索它的值一个词：

{foreach from=$variants item=variant}
{if $variant.group|stristr:'Dimensioni'}
{$variant.group} 
{/if}
{/foreach}

输出：

Dimensioni Fiore 1
Dimensioni Fiore 2
Dimensioni Fiore 3

现在我想计算数组中的总出现次数(应该是3(：

{$variant.group|count}

输出：

1
1
1

我必须计算出现次数，就好像它们是2次或更多次一样，它必须做一些事情，但每个数组的输出只计算1次，而不是总数。实现这一目标的方法是什么？

谢谢。

您可以使用counter来执行此操作：

{counter print=false start=0 name=Dimensioni assign=dimensioniCount}
{foreach from=$variants item=variant}
{if $variant.group|stristr:'Dimensioni'}
{$variant.group}
{counter name=Dimensioni}
{/if}
{/foreach}
{if $dimensioniCount>=2}
<h1>Do something here</h1>
{/if}
