3 个解决方案

#1

POST will send all values if you mark them as selected using javascript right before submitting. $_POST["check"] is an array. use a foreach and get all values from that array.

如果您在提交前使用javascript将其标记为已选中，POST将发送所有值。 $ _POST [“check”]是一个数组。使用foreach并从该数组中获取所有值。

As you're loop through post data which is going to be an array I believe that is why only one of their elements are being returned.

当你循环遍历将成为数组的post数据时，我相信这就是为什么只返回其中一个元素的原因。

You might want to try something like this:

您可能想尝试这样的事情：

foreach ($_POST as $key => $val) {
    if ($key == "check" || $key == "gen") { // If this is an array post field
        foreach ($val as $val2) { // We need to loop through again since they're array post fields
            $actVal .= "'" . strtolower($val2) . "'";
        }   
    } else {
        $actVal .= "'".strtolower($key)."|".strtolower($val)."',";
    }
    //$sqlin .= " ".strtolower($key)." VARCHAR(255) , "; // Worry about this separately, should be the same process
}

I can't figure out a way around that one. But there is an alternative:

我无法找到解决这个问题的方法。但还有另一种选择：

<input type="checkbox" name="check" value="php" />PHP
<input type="hidden" name="checklist" value="php" />

<input type="checkbox" name="check" value="MySQL" />MySQL
<input type="hidden" name="checklist" value="MySQL" />

The idea is to store the list of all the values of a checkbox/radio button, in a hidden input so that you get the list of those values server-side, when the form is submitted.

我们的想法是在隐藏的输入中存储复选框/单选按钮的所有值的列表，以便在提交表单时获取服务器端的值列表。

BTW, why do you need it anyway?

顺便说一句，你为什么还需要呢？
