Smarty: How to reference to the associative array index
提问by Edoardo Vacchi
Array $imagelist:
Array (
[additional] => Array (
[count] => 2
[image] => Array (
[nokia_e61_1.jpg] => Array (
[name_body] => nokia_e61_1
[name_ext] => jpg
)
[nokia_e61_2.jpg] => Array (
[name_body] => nokia_e61_2
[name_ext] => jpg
)
[nokia_e61_3.jpg] => Array (
[name_body] => nokia_e61_3
[name_ext] => jpg
)
[nokia_e61_4.jpg] => Array (
[name_body] => nokia_e61_4
[name_ext] => jpg
)
)
)
[main] => nokia_e61
)
The value nokia_e61_1.jpgis kept in {$getvars.imagename}.
该值nokia_e61_1.jpg保留在{$getvars.imagename}.
I wrote {$imagelist.additional.image.`$getvars.imagename`.name_body}but it doesn't work.
我写了{$imagelist.additional.image.`$getvars.imagename`.name_body}但它不起作用。
Please help.
请帮忙。
回答by Edoardo Vacchi
see if {$imagelist.additional.image[$getvars.imagename].name_body}works
看看是否{$imagelist.additional.image[$getvars.imagename].name_body}有效

I don't like smarty for this, nevertheless I use it. Here's extract form documentation
我不喜欢 smarty，但我使用它。这是提取表格文档
{$foo.$bar} <-- display variable key value of an array, similar to PHP $foo[$bar]
To be able to do it, you have to
为了能够做到这一点，你必须
{assign var='key' value=$getvars.imagename}
{$imagelist.additional.image.$key.name_body}
Hope it helps
希望能帮助到你

Restructure the array, the keys for the inner 'images' offset are redundant anyway:
重组数组，内部“图像”偏移的键无论如何都是多余的：
$imagelist = array('additional' => array('count' => 2,
'image' => array(
array('name_body' => 'nokia_e61_1',
'name_ext' => 'jpg'),
array('name_body' => 'nokia_e61_2',
'name_ext' => 'jpg'),
array('name_body' => 'nokia_e61_3',
'name_ext' => 'jpg'),
array('name_body' => 'nokia_e61_4',
'name_ext' => 'jpg')
)
),
'main' => 'nokia_e61'
);
Gives you numerically indexed images:
为您提供数字索引图像：
array(2) {
["additional"]=>
array(2) {
["count"]=>
int(2)
["image"]=>
array(4) {
[0]=>
array(2) {
["name_body"]=>
string(11) "nokia_e61_1"
["name_ext"]=>
string(3) "jpg"
}
[1]=>
array(2) {
["name_body"]=>
string(11) "nokia_e61_2"
["name_ext"]=>
string(3) "jpg"
}
[2]=>
array(2) {
["name_body"]=>
string(11) "nokia_e61_3"
["name_ext"]=>
string(3) "jpg"
}
[3]=>
array(2) {
["name_body"]=>
string(11) "nokia_e61_4"
["name_ext"]=>
string(3) "jpg"
}
}
}
["main"]=>
string(9) "nokia_e61"
}
//and then the smarty bit
{$imagelist.additional.image[0].name_body}
{$imagelist.additional.image[1].name_body}
{$imagelist.additional.image[2].name_body}
{$imagelist.additional.image[3].name_body}

{php}echo $imagelist['additional']['image'][$getvars['imagename']]['name_body'];{/php}
