我想从下面的html表单构建一个php数组结构。
我有下面的HTML表单
<!-- ROOM 1-->
<div class="row">
<div class="col-xs-4">
<label>ADULTS</label>
<div class="selector">
<select id='adults-1' name="rooms[0][adult]" class="full-width">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
</select>
</div>
</div>
<div class="col-xs-4">
<label>Copii</label>
<div class="selector">
<select id='kids-1' name="rooms[0][child]" class="full-width">
<option value="0">0</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
</div>
</div>
</div>
<div class="age-of-children no-display">
<div class="row">
<div class="col-xs-4 child-age-field">
<label>Copil 1</label>
<div class="selector validation-field">
<select class="full-width" name="rooms[0][age]" id='age-1'>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
<option value="6">6</option>
<option value="7">7</option>
<option value="8">8</option>
<option value="9">9</option>
<option value="10">10</option>
<option value="11">11</option>
</select>
</div>
</div>
</div>
</div>
<!-- ROOM 2-->
<div class="row">
<div class="col-xs-4">
<label>ADULTS</label>
<div class="selector">
<select id='adults-1' name="rooms[1][adult]" class="full-width">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
</select>
</div>
</div>
<div class="col-xs-4">
<label>Copii</label>
<div class="selector">
<select id='kids-1' name="rooms[1][child]" class="full-width">
<option value="0">0</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
</div>
</div>
</div>
<div class="age-of-children no-display">
<div class="row">
<div class="col-xs-4 child-age-field">
<label>Copil 1</label>
<div class="selector validation-field">
<select class="full-width" name="rooms[1][age]" id='age-1'>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
<option value="6">6</option>
<option value="7">7</option>
<option value="8">8</option>
<option value="9">9</option>
<option value="10">10</option>
<option value="11">11</option>
</select>
</div>
</div>
</div>
</div>
到目前为止，我的PHP代码是
$result = array();
if(!empty($_POST['rooms'])) {
foreach($_POST['rooms'] as $k => $info) {
for($y = 0; $y < $info['adult']; $y++) {
$result[$k][]['paxType'] = 'Adult';
}
for($y = 0; $y < $info['child']; $y++) {
$result[$k][]['paxType'] = 'Child';
}
}
}
这在一定程度上起作用，但并没有像预期的那样起作用（不包括儿童年龄）。例如，预期输出：1号房间=1名成年人选择2号房间=2名成年人选择1名儿童选择8岁
Array
(
[0] => Array
(
[0] => Array
(
[paxType] => Adult
)
)
[1] => Array
(
[0] => Array
(
[paxType] => Adult
)
[1] => Array
(
[paxType] => Adult
)
[2] => Array
(
[paxType] => Child
[age] => 8
)
)
)
如果你需要更多信息，请告诉我。
我认为变量$y是错误的。请尝试以下代码：
$result = array();
if(!empty($_POST['rooms'])) {
foreach($_POST['rooms'] as $k => $info) {
for($y = 0; $y < $info['adult']; $y++) {
$result[$k][]['paxType'] = 'Adult';
}
for($z = 0; $z < $info['child']; $z++) {
$result[$k][]['paxType'] = 'Child';
}
}
}
更新：
/**
* @param array $array
* @param int|string $position
* @param mixed $insert
*/
function array_insert(&$array, $position, $insert)
{
if (is_int($position)) {
array_splice($array, $position, 0, $insert);
} else {
$pos = array_search($position, array_keys($array));
$array = array_merge(
array_slice($array, 0, $pos),
$insert,
array_slice($array, $pos)
);
}
}
整数用法：
$arr = ["one", "two", "three"];
array_insert(
$arr,
1,
"on-half"
);
// ->
array (
0 => 'one',
1 => 'on-half',
2 => 'two',
3 => 'three',
)
字符串用法：
$arr = [
"name" => [
"type" => "string",
"maxlength" => "30",
],
"email" => [
"type" => "email",
"maxlength" => "150",
],
];
array_insert(
$arr,
"email",
[
"phone" => [
"type" => "string",
"format" => "phone",
],
]
);
// ->
array (
'name' =>
array (
'type' => 'string',
'maxlength' => '30',
),
'phone' =>
array (
'type' => 'string',
'format' => 'phone',
),
'email' =>
array (
'type' => 'email',
'maxlength' => '150',
),
)
您还可以查看php.net手册：http://php.net/manual/en/function.array-push.php
尝试更改
for($y = 0; $y < $info['child']; $y++) {
$result[$k][]['paxType'] = 'Child';
}
至
for($y = 0; $y < $info['child']; $y++) {
$result[$k][] = array('paxType' => 'Child', 'age' => $info['age']);
}
你想让所有的"孩子"都有相同的年龄吗？与中一样，如果用户选择房间[1][child]=3和房间[1][age]=5，是否希望所有3个"child"数组的"age"都设置为5？
