首先，设置排序算法的方法取决于这些街道名称和地址号码存储的位置/方式。a中的单线meta_key, 两个独立的meta_key 由于某种原因等输入内容
OP正在处理存储为的地址post_title 价值观因此，以下假设为字符串：
主街1234号
其余部分，匹配和更新页面menu_order 关键相当简单。
也许是这样一个过程：
来自init 挂钩：
[order_pages_by_values()]
获取页面对象数组：
[$pages = get_pages_wrapper();]
对于每个页面对象，将ID传递给获取数字/街道值的函数：
（1）[$addresses = extract_and_conflate_address( $pages );]
（2）[$number = get_address_number( $page->ID );]
（3）[$street = get_address_street( $page->ID );]
4） [
$split = explode( \' \', $address, 2 );
if ( $value === \'number\' ) {
$return = $split[0];
}
elseif ( $value === \'street\' ) {
$return = $split[1];
}]
将数字和街道值添加到数组中key => value, i、 e。numeric => street:
[$address_k_v[$number] = $street;]
对该数组的值和键进行排序，然后创建多维数组street => array ( numeric, )
（1）[$flatten_array = sort_values_and_keys_and_flatten( $addresses )]
（2）[
foreach( $array as $n => $s ) {
if ( array_key_exists( $s, $multi_array ) ) {
$multi_array[$s][] = $n;
}
else {
$multi_array[$s] = array( $n );
}
}
]
对street 外部数组的键，然后针对每个street, 对内部数值数组排序
（1）[ksort($multi_array);]
（2）[foreach ($multi_array as $street => $numbers_array ) {
asort($numbers_array);]
（现在已排序）number => street 输入，使其成为字符串number-street, 并将其添加到新阵列中每个（现在已排序）street => array ( numeric ) （内部数组），添加字符串number-street 到新阵列：
[foreach( $numbers_array as $na ) {
$flatten_array[] = $na .\'-\'. $street;]
对于每个页面对象，再次获取数字和街道，这次使用它们创建字符串numberic-street:
$number = get_address_number( $page->ID );
$street = get_address_street( $page->ID );
$match_string = $number . \'-\' . $street;`
搜索排序的数组numberic-street 此的字符串numberic-street 字符串，返回要设置的索引号$menu_order:[$menu_order = array_search( $match_string, $flatten_array );]
使用创建post的参数数组ID => page->ID 和menu_order => index number:
$update_post_args = array( \'ID\' => $page->ID,
\'menu_order\' => $menu_order
);
用这些参数更新帖子：[wp_update_post( $update_post_args )]
如果没有这些地址字段的存储位置，就无法猜测解决方案，但我已经介绍了一种可能的方法，使用explode 在…上post_title 以防这是你当前噩梦的一部分
下面只是一个可能的过程的示例，当然，在全面测试之前先对其进行测试。我可能会将其全部封装在一个插件类中。
add_action( \'init\', \'order_pages_by_values\' );

$args = array( \'post_type\' => \'page\',
\'post_status\' => \'publish\'

foreach ( $pages as $page ) {
$number = get_address_number( $page->ID ); //depends on where value is stored
$street = get_address_street( $page->ID ); //depends on where value is store
$address_k_v[$number] = $street;
}
return $address_k_v;
}
//old version, several issues with this.
// First, it is more of a re-sort, ignoring previously sorted items.
/// Second, it cannot preserve instances where same post box address (1234) for different street would overwrite previous entry.

更新我更新了上面的代码块，但下面是排序函数的快速测试示例。我说不出它有多经济，但它在我这边起作用了。因为它正在返回$flatten_array 在上一个版本中，请注意，我已经从order_pages_by_value()Here is the testable code sample for the sort:
//array as would be returned by extract_and_conflate_addresses()
$the_array = array(
\'1234\' => \'Main Street\',
\'100\' => \'Avenue Road\',
\'105\' => \'Avenue Road\',
\'106\' => \'Avenue Road\',
\'106a\' => \'Avenue Road\',
\'107\' => \'Avenue Road\',
\'103\' => \'Front Street\',
\'42\' => \'5 Lane\',
\'42000\' => \'B Street\',
);
function sort_values_and_keys_and_flatten( $array ) {
//need array declared already for conditional inside foreach
$multi_array = array();
foreach( $array as $n => $s ) {
//makes sure Street doesn\'t exist yet. If it does, append, if not add.
if ( array_key_exists( $s, $multi_array ) ) {
$multi_array[$s][] = $n;
}
else {
$multi_array[$s] = array( $n );
}
}
//sort the street names
ksort($multi_array);
foreach ($multi_array as $street => $numbers_array ) {
//sort the numerical addresses
asort($numbers_array);
//build $flatten_array
foreach( $numbers_array as $na ) {
$flatten_array[] = $na .\'-\'. $street;
}
}
return $flatten_array;
}
$test = sort_values_and_keys_and_flatten( $the_array );
print_r($test);
That should yield:
Array
(
[0] => 42-5 Lane
[1] => 100-Avenue Road
[2] => 105-Avenue Road
[3] => 106-Avenue Road
[4] => 106a-Avenue Road
[5] => 107-Avenue Road
[6] => 42000-B Street
[7] => 103-Front Street
[8] => 1234-Main Street
)
