同一个地方绊倒两次，记录一下哈
1）前台表单，看 name
<div class="tab-pane row " id="tab-1" >
<input type="hidden" name="data[1][Type]" value='' class="form-control" id="data[1][Type]">
<input class="form-control" type="text" id="data[1][UnitPrice]" name="data[1][UnitPrice]" value="" placeholder="请输入单价" >
<input class="form-control" type="text" id="data[1][Quantity]" name="data[1][Quantity]" value="" placeholder="请输入数量" >
<input class="form-control" type="text" id="data[1][Name]" name="data[1][Name]" value="" placeholder="请输入费用名称" >
<input class="form-control" type="text" id="data[1][Description]" name="data[1][Description]" value="" placeholder="请输入费用描述" >
</div>
<div class="tab-pane row " id="tab-2" >
<input type="hidden" name="data[2][Type]" value='' class="form-control" id="data[2][Type]">
<input class="form-control" type="text" id="data[2][UnitPrice]" name="data[2][UnitPrice]" value="" placeholder="请输入单价" >
<input class="form-control" type="text" id="data[2][Quantity]" name="data[2][Quantity]" value="" placeholder="请输入数量" >
<input class="form-control" type="text" id="data[2][Name]" name="data[2][Name]" value="" placeholder="请输入费用名称" >
<input class="form-control" type="text" id="data[2][Description]" name="data[2][Description]" value="" placeholder="请输入费用描述" >
</div>
2）后台打印数据
Array
(
[1] => Array
(
[Type] =>
[UnitPrice] =>
[Quantity] =>
[Name] =>
[Description] =>
)
[2] => Array
(
[Type] =>
[UnitPrice] =>
[Quantity] =>
[Name] =>
[Description] =>
)
)
