在打印$my_values['outer_group']['fieldset']之后，根据数据，我得到以下输出：
Array
(
[fieldset] => Array
(
[1] => Array
(
[title] => Dummy_Value1
[inner_group] => Array
(
[fieldset] => Array
(
[1] => Array
(
[id] => 11
[title] => Dummy_Value11
)
[2] => Array
(
[id] => 12
[title] => Dummy_Value12
)
[3] => Array
(
[id] => 13
[title] => Dummy_Value13
)
[actions] => Array
(
[add] => Add InnerGroup
[remove] => Remove InnerGroup
)
)
)
)
[2] => Array
(
[title] => Dummy_Value2
[inner_group] => Array
(
[fieldset] => Array
(
[1] => Array
(
[id] => 21
[title] => Dummy_Value21
)
[actions] => Array
(
[add] => Add InnerGroup
)
)
)
)
[actions] => Array
(
[add] => Add OuterGroup
[remove] => Remove OuterGroup
)
)
)
我的要求是重新索引输出数据，因此我执行了以下代码来重新索引相同的数据：
<?php
if (isset($my_values['outer_group']) && !empty($my_values['outer_group'])) {
$outer_types = $my_values['outer_group']['fieldset'];
$inner = [];
foreach ($outer_types as $outer_key => $outer_value) {
if (is_numeric($outer_key)) {
if (isset($outer_value['inner_group']['fieldset'])) {
foreach ($outer_value['inner_group']['fieldset'] as $k => $v) {
if (is_numeric($k)) {
$inner[] = [
'id' => $v['id'],
'title' => !empty($v['title']) ? $token->replace($v['title']) : NULL,
];
}
}
}
$my_values['outer'][$outer_key] = [
'title' => !empty($outer_value['title']) ? $token->replace($outer_value['title']) : NULL,
'inner' => $inner,
];
}
}
}
根据输出重新索引，但数据中有一些错误。填充[inner]数据时遇到麻烦，以下是相同数据的输出：
Array
(
[0] => Array
(
[title] => Dummy_Value1
[inner] => Array
(
[0] => Array
(
[id] => 11
[title] => Dummy_Value11
)
[1] => Array
(
[id] => 12
[title] => Dummy_Value12
)
[2] => Array
(
[id] => 13
[title] => Dummy_Value13
)
)
)
[1] => Array
(
[title] => Dummy_Value2
[inner] => Array
(
[0] => Array
(
[id] => 11
[title] => Dummy_Value11
)
[1] => Array
(
[id] => 12
[title] => Dummy_Value12
)
[2] => Array
(
[id] => 13
[title] => Dummy_Value13
)
[3] => Array
(
[id] => 21
[title] => Dummy_Value21
)
)
)
)
应该是：
Array
(
[0] => Array
(
[title] => Dummy_Value1
[inner] => Array
(
[0] => Array
(
[id] => 11
[title] => Dummy_Value11
)
[1] => Array
(
[id] => 12
[title] => Dummy_Value12
)
[2] => Array
(
[id] => 13
[title] => Dummy_Value13
)
)
)
[1] => Array
(
[title] => Dummy_Value2
[inner] => Array
(
[0] => Array
(
[id] => 21
[title] => Dummy_Value21
)
)
)
)
