【问题描述】：
我有 JSON 对象数组。我正在尝试使用 usort 对数组进行排序。我想使用来自field_listing_order 的value 字段。它使用值排序。我错过了一些东西，但无法弄清楚。请查看代码。谢谢！
stdClass Object
(
[node_title] => abc
[nid] => 2281
[field_api_order_value] => 201
[field_node_entity_type] => node
[_data] => Array
(
[nid] => Array
(
[entity_type] => node
[entity] => stdClass Object
(
[title] => abc
[field_listing_order] => Array
(
[und] => Array
(
[0] => Array
(
[value] => 8
[format] =>
[safe_value] => 8
)
)
)
)
)
)
)
stdClass Object
(
[node_title] => abc
[nid] => 2243
[field_api_order_value] => 204
[field_node_entity_type] => node
[_data] => Array
(
[nid] => Array
(
[entity_type] => node
[entity] => stdClass Object
(
[title] => abc
[field_listing_order] => Array
(
[und] => Array
(
[0] => Array
(
[value] => 3
[format] =>
[safe_value] => 3
)
)
)
)
)
)
) stdClass Object
(
[node_title] => abc
[nid] => 2431
[field_api_order_value] => 242
[field_node_entity_type] => node
[_data] => Array
(
[nid] => Array
(
[entity_type] => node
[entity] => stdClass Object
(
[title] => abc
[field_listing_order] => Array
(
[und] => Array
(
[0] => Array
(
[value] => 1
[format] =>
[safe_value] => 1
)
)
)
)
)
)
)
等等……
foreach ($view->result as $result) {
$node = $result->_data['nid']['entity'];
$listing_order = $node->field_listing_order[LANGUAGE_NONE][0];
.....
// code goes here and it works well. sorting issue
}
usort ($node->field_listing_order[LANGUAGE_NONE][0], function($a, $b){
return strcmp($a->value, $b->value);
}); ?>
【问题讨论】：
-
您想对
field_listing_order或“全局”对象中的元素进行排序？ -
这是关于使用不在内部的值对全局对象进行排序。 $a 和 $b 用于比较值。
