我知道之前在stackoverflow上曾问过这个问题，但我仍然遇到困难。
我想知道如何从多维数组中获取选定的值。 插件的简化代码和原始数组：
$options_label =
Array (
[0] => Array (
[0] => Array (
[0] => 17
[1] => [{"id":"1","label":"350 cm x 250 cm"},{"id":"2","label":"400 cm x 250 cm"},{"id":"3","label":"450 cm x 250 cm"}]
[2] => Array (
...
)
)
[1] => Array (
[0] => 5
[1] => [{"id":"3","label":"Rechts"},{"id":"4","label":"Links"}]
[2] => Array (
...
)
)
)
[1] => Array
(
[0] => Array (
[0] => 11
[1] => [{"id":"1","label":"300 cm x 250 cm"},{"id":"2","label":"350 cm x 250 cm"}]
[2] => Array (
...
)
)
)
)
我想创建一个使用[1]（与json相关的代码）中的值的新数组，因此新数组应如下所示：
$new_array(
Array (
[0] => array (
[0] => array (
[0] => array (
[id] => 1
[label] => 350 cm x 250 cm
)
[1] => array (
[id] => 2
[label] => 400 cm x 250 cm
)
[2] => array (
[id] => 3
[label] => 450 cm x 250 cm
)
)
[1] => array (
[0] => Array (
[id] => 3
[label] => Rechts
)
[1] => Array (
[id] => 4
[label] => Links
)
)
)
[1] => array (
[0] => array (
[0] => array (
[id] => 1
[label] => 300 cm x 250 cm
)
[1] => array (
[id] => 2
[label] => 350 cm x 250 cm
)
)
)
)
非常感谢任何指导。

我猜测这里似乎有JSON字符串，我们希望将其替换为一个数组，我们可能想要类似以下内容：
$options_label = array(
"0" => array(
"0" => array(
"0" => 17,
"1" => '[{"id":"1","label":"350 cm x 250 cm"},{"id":"2","label":"400 cm x 250 cm"},{"id":"3","label":"450 cm x 250 cm"}]',
"2" => array(),
),
"1" => array(
"0" => 5,
"1" => '[{"id":"3","label":"Rechts"},{"id":"4","label":"Links"}]',
"2" => array(),
),
),
"1" => array
(
"0" => array(
"0" => 11,
"1" => '[{"id":"1","label":"300 cm x 250 cm"},{"id":"2","label":"350 cm x 250 cm"}]',
"2" => array(),
),
),
);
$new_options_label = array();
foreach ($options_label as $key1 => $value1) {
foreach ($value1 as $key2 => $value2) {
foreach ($value2 as $key3 => $value3) {
if (json_decode($value3, true)) {
$options_label[$key1][$key2][$key3] = json_decode($value3, true);
}
}
}
}
var_dump($options_label);
array(2) {
[0]=>
array(2) {
[0]=>
array(3) {
[0]=>
int(17)
[1]=>
array(3) {
[0]=>
array(2) {
["id"]=>
string(1) "1"
["label"]=>
string(15) "350 cm x 250 cm"
}
[1]=>
array(2) {
["id"]=>
string(1) "2"
["label"]=>
string(15) "400 cm x 250 cm"
}
[2]=>
array(2) {
["id"]=>
string(1) "3"
["label"]=>
string(15) "450 cm x 250 cm"
}
}
[2]=>
array(0) {
}
}
[1]=>
array(3) {
[0]=>
int(5)
[1]=>
array(2) {
[0]=>
array(2) {
["id"]=>
string(1) "3"
["label"]=>
string(6) "Rechts"
}
[1]=>
array(2) {
["id"]=>
string(1) "4"
["label"]=>
string(5) "Links"
}
}
[2]=>
array(0) {
}
}
}
[1]=>
array(1) {
[0]=>
array(3) {
[0]=>
int(11)
[1]=>
array(2) {
[0]=>
array(2) {
["id"]=>
string(1) "1"
["label"]=>
string(15) "300 cm x 250 cm"
}
[1]=>
array(2) {
["id"]=>
string(1) "2"
["label"]=>
string(15) "350 cm x 250 cm"
}
}
[2]=>
array(0) {
}
}
}
}

代码有点复杂，但是我还是要发布它。
global $wpdb;
$table = $wpdb->base_prefix . 'woopricesim_simulations';
$existing = $wpdb->get_row( $wpdb->prepare( "SELECT * FROM " . $table . " WHERE order_id = %d", $order->get_order_number() ), ARRAY_A );
$simulation_data = json_decode($existing['simulation_data'], true);
$simulators = json_decode($existing['simulators'], true);
$fields = array();
foreach($simulation_data as $key => $value) {
$fields[] = $value['simulator_fields_data'];
}
此输出为
fields:Array
(
[0] => Array
(
[aws_price_calc_1] => 2
[aws_price_calc_2] => 1
[aws_price_calc_3] => 2
)
[1] => Array
(
[aws_price_calc_12] => 1
[aws_price_calc_2] => 3
[aws_price_calc_14] => 1
[aws_price_calc_13] => 1
[aws_price_calc_6] =>
[aws_price_calc_18] => 1
[aws_price_calc_17] => 1
[aws_price_calc_15] => 1
)
)
我需要将其转换为名称（标签）并选择所选内容。
$labels = array();
$data = array();
$new_options = array();
$final = array();
foreach( $fields as $field_key => $field_value ){
$new_labels = array();
$new_data = array();
foreach( $field_value as $key => $value ){
$field_id = str_replace("aws_price_calc_", "", $key);
$field_table = $wpdb->base_prefix . 'woopricesim_fields';
$field_data = $wpdb->get_row( $wpdb->prepare( "SELECT * FROM " . $field_table . " WHERE id = %d", $field_id ), ARRAY_A );
//$new_data[] = json_decode( $field_data['options'], true );
$new_data[] = $field_data['options'];
$new_labels[] = $field_data['label'];
}
$labels[] = $new_labels;
$data[] = $new_data;
}
标签工作正常。
labels:Array
(
[0] => Array
(
[0] => Size
[1] => Operation Side
[2] => Operation Type
)
[1] => Array
(
[0] => Size
[1] => Operation Side
[2] => Operation Type
[3] => Color
[4] => Fabric Color
[5] => Strips
[6] => Sensor
[7] => Delivery
)
)
数据现在看起来像这样。
data:Array
(
[0] => Array
(
[0] => {"items_list_id":"17","picklist_items":"[{\"id\":\"1\",\"label\":\"350 cm x 250 cm\",\"value\":\"0\",\"order_details\":\"\",\"tooltip_message\":\"\",\"tooltip_position\":\"none\",\"default_option\":\"1\"},{\"id\":\"2\",\"label\":\"400 cm x 250 cm\",\"value\":\"99\",\"order_details\":\"\",\"tooltip_message\":\"\",\"tooltip_position\":\"none\",\"default_option\":\"0\"}]
[2] => {"items_list_id":"7","picklist_items":"[{\"id\":\"4\",\"label\":\"Electric\",\"value\":\"0\",\"order_details\":\"\",\"tooltip_message\":\"\",\"tooltip_position\":\"none\",\"default_option\":\"0\"},{\"id\":\"5\",\"label\":\"Motor\",\"value\":\"95\",\"order_details\":\"\",\"tooltip_message\":\"\",\"tooltip_position\":\"none\",\"default_option\":\"0\"},{\"id\":\"6\",\"label\":\"RTS + sensor\",\"value\":\"210\",\"}]
)
[1] => Array
(
[0] => {...}
[1] => {...}
[2] => {...}
[3] => {...}
[4] => {...}
[5] => {...}
[6] => {...}
[7] => {...}
)
)
从现在开始，我需要创建一个新数组，其中仅包含来自picklist_items的值，也只有来自id和label的值。
我使用的简单的foreach，可以返回Undefined index: picklist或id/label。
我的最终目标是用标签名称和所选内容替换$fields。
例如。 [aws_price_calc_1] => 2将成为Size => 400 cm x 250 cm。
