提前感谢。这里有一个函数，可以按您希望的方式对列表进行排序。它首先在数组的
标题可排序行function sort_list($list, $field, $ascending = true) {
$headers = array_values($list['header'])[0];
if (($key = array_search($field, array_column($headers, 'content'))) === false || $headers[$key]['sortable'] == 0) {
// can't find field or field is not sortable, do nothing
return $list;
}
usort($list['row'], function ($a, $b) use ($key, $ascending) {
return $ascending ? $a[$key]['sort_value'] <=> $b[$key]['sort_value'] : $b[$key]['sort_value'] <=> $a[$key]['sort_value'];
});
return $list;
}
您忘记发布代码了
function sort_list($list, $field, $ascending = true) {
$headers = array_values($list['header'])[0];
if (($key = array_search($field, array_column($headers, 'content'))) === false || $headers[$key]['sortable'] == 0) {
// can't find field or field is not sortable, do nothing
return $list;
}
usort($list['row'], function ($a, $b) use ($key, $ascending) {
return $ascending ? $a[$key]['sort_value'] <=> $b[$key]['sort_value'] : $b[$key]['sort_value'] <=> $a[$key]['sort_value'];
});
return $list;
}
sort_list($data, 'Price');
