    echo "Field ".htmlspecialchars($key)." is ".htmlspecialchars($value)."<br>"
}

推荐答案

仅提交"成功"控件.未选中的复选框或单选按钮不是"成功".

Only "successful" controls are submitted. An unchecked checkbox or radio button is not "successful".

您需要使用隐藏输入声明默认值.确保隐藏的输入位于复选框之前，因此如果选中此复选框，则由于名称相同，它将覆盖默认的隐藏输入:

You need to declare a default value with a hidden input. Make sure the hidden input comes before the checkbox so if the checkbox is checked it will override the default hidden input since the names are the same:

<input name="p-sis-0110-1" type="hidden" value="0">
<input name="p-sis-0110-1" type="checkbox" value="1">

要使用数组，您需要显式定义索引，以使它们相同:

To use an array you need to explicitly define the indexes so they are the same:

<input name="input[0]" type="hidden" value="0">
<input name="input[0]" type="checkbox" value="1">
