If i understood correctly, you are generating the names of the inputs dinamically, using a $a increment variable. 如果我理解正确，则可以使用$ a增量变量来动态生成输入的名称。 But for some reason you cant recalculate those names when you post so you are not able to get the posted values. 但是由于某些原因，您在发布时无法重新计算这些名称，因此无法获取发布的值。 You can resolve this in many ways, one is to generate input names this way: 您可以通过多种方式解决此问题，一种方式是通过这种方式生成输入名称：

<input type="checkbox" name="blah[$a]"/>
<select name="bleh[$a]">...</select>

This will result in a post with an array like so: 这将导致发布带有如下数组的数组：

array( 
    "blah" => array($a => valueofcheckbox),
    "bleh" => array($a => valueofselect)
)

That you can parse with a simple foreach 可以用一个简单的foreach解析

foreach ($_POST["blah"] as $a => $value) {
    ...
}

foreach ($_POST["bleh"] as $a => $value) {
    ...
}

I dont quite understand the enable/disable logic, as i said before, thats some messy code, but you should know that disabled fields will not get posted. 正如我之前所说，我不太了解启用/禁用逻辑，多数民众赞成在一些凌乱的代码，但您应该知道禁用字段不会被张贴。

PS: The code i posted is pseudo-code. PS：我发布的代码是伪代码。
