这是我的状态。php文件的代码，但在张贴状态它只显示一件事，即type_unknown，但我不知道为什么它不能正常工作。type_unknown也是这个代码中的一个命令，请通读这个命令，然后提出您想要的任何更改。

如果问题出现在这一行:
if($_POST['type'] != "a" || $_POST['type'] != "c"){
那么，这意味着您没有包含名称为type的输入表单，或者帖子数据可能根本没有传输。检查一下你的HTML表单是否有type
问题似乎是条件中的逻辑。如果将其更改为:
if($_POST['type'] != "a" && $_POST['type'] != "c")
则条件语句应按预期工作。请注意，编辑将'||'更改为'&&'。
为什么要编辑这个?假设:$_POST['type'] == "a"。如果是，则:
$_POST['type'] != "a" // false
$_POST['type'] != "c" // true
因此，条件的计算结果为:if(false || true)，而后者的计算结果为if(true)。只有当$_POST['type'] != "a"和$_POST['type'] != "c"时，原始逻辑才会起作用(这种情况永远不会发生，因为它要求同一变量同时具有两个值)。
