我正在尝试使用php将动态生成的复选框、标签和选择标签的值保存到mysql数据库中，在这个标签中我正在从不同的数据库检索值，并且我正在尝试保存带有标签值和选定的选中字段的数据选项值，但我无法做到这一点，请建议我哪里做错了。

最佳答案
如果我理解正确，您将使用 $a 增量变量动态生成输入的名称。但由于某种原因，您在发布时无法重新计算这些名称，因此您无法获取发布的值。您可以通过多种方式解决此问题，其中一种是通过这种方式生成输入名称:
<input type="checkbox" name="blah[$a]"/>
<select name="bleh[$a]">...</select>
这将产生一个带有如下数组的帖子:
array(
"blah" => array($a => valueofcheckbox),
"bleh" => array($a => valueofselect)
)
您可以使用简单的 foreach 进行解析
foreach ($_POST["blah"] as $a => $value) {
...
}
foreach ($_POST["bleh"] as $a => $value) {
...
}
我不太理解启用/禁用逻辑，正如我之前所说，那是一些困惑的代码，但您应该知道禁用的字段不会被发布。
PS:我发布的代码是伪代码。
