[英]Consuming complex array with keys in php mustache
I have following structure of array arr
我有数组arr
以下结构
Array
(
[1] => Array
(
[width] => 600
[pages] => Array
(
[0] => Array
(
[bgColor] => 'red'
)
)
)
[3] => Array
(
[width] => 400
[pages] => Array
(
[0] => Array
(
[bgColor] => 'blue'
)
)
)
)
Currently I am passing data as, 目前,我正在传递数据,
$tpl->render(array(
'arr' => new ArrayIterator($arr)
));
In in mustache template, I am consuming it like, 在小胡子模板中,我正在消费它,
{{#arr}}
{{width}}
{{/arr}}
It gives me width
correctly. 它给我正确的width
。 But now I want the keys
of that array ( 1
for first and 3
for second one) and also the total no of elements in pages
key. 但现在我想的keys
该数组的( 1
为第一和3
为第二个),并且还在总没有元素的pages
键。
How can I do this mustache ? 我该怎么留胡子?
Okay, I understand that mustache cannot keep track of index
of array and it needs everything in hash
. 好的,我知道小胡子不能跟踪数组的index
,它需要hash
所有内容。
So, I am using following technique, it works but little bit ugly. 因此,我正在使用以下技术,但效果有点差。
function prepareForMustache ($arr) {
foreach($arr as $k => &$v) {
$v['key'] = $k;
$v['pagesCount'] = count($v['pages']);
}
}
$arr = prepareForMustache($arr);
$tpl->render(array(
'arr' => new ArrayIterator($arr)
));
And consuming in mustache template as, 并在胡子模板中消费为
{{#arr}}
{{width}}
{{key}}
{{pagesCount}}
{{/arr}}
