HTML表单、JSON和PHP
我有一个HTML表单，它使用stringify解析为JSON，然后与mysqli数据库通信 我遇到的问题是，表单包含了很多复选框，当相关时会选中这些复选框，只有选中的复选框才能在表单提交操作中得到输出。这意味着，当我在后面阅读JSON时，我永远无法确定它的结构，这使得访问解码JSON数组的特定元素变得不可能 表单复选框部分如下所示：HTML表单、JSON和PHP,php,json,Php,Json,我有一个HTML表单，它使用stringify解析为JSON，然后与mysqli数据库通信 我遇到的问题是，表单包含了很多复选框，当相关时会选中这些复选框，只有选中的复选框才能在表单提交操作中得到输出。这意味着，当我在后面阅读JSON时，我永远无法确定它的结构，这使得访问解码JSON数组的特定元素变得不可能 表单复选框部分如下所示： <!-- Couriers section --> <div clas

有人能回顾一下，让我知道正确的方法来获得我正在努力争取的结果和可用性吗？尝试在名称中添加括号，这会使您的复选框变成一个值数组
name="courierCheck[]"
如果我正确理解了您的问题，您可以使用resultype“MYSQLI_ASSOC”：“返回一个字符串的关联数组，该数组表示结果集中提取的行，其中数组中的每个键表示结果集中一个列的名称，如果结果集中没有更多行，则为NULL。”或者使用MYSQLI_fetch_ASSOC（）：这将使您的键成为您的列名，您可以直接访问它们的值，而不必担心索引的移动。谢谢@Rami，我想我可能需要从数据库中更好地控制这一点。目前，数据库只有3列—ID、quoteNumber、JSON—编码的JSON字符串被转储到最后一列，然后在以后检索。这很有趣，我从未使用关系数据库将原始JSON存储到列中，以便以后从所述列提取和解析数据。我相信，如果有特定的列并存储它们各自的值，您会得到更好的服务。我相信这会简化你的工作。或者，我会想象像mongo这样的文档库更适合JSON的存储/处理。我本想提高效率，但却给自己造成了限制。谢谢你的建议嗨，我试过了，JSON返回为{“名称”：“courierCheck[]，“值”：“interlink”}，{“名称”：“courierCheck[]，“值”：“intersoft”}，{“名称”：“courierCheck[]，“值”：“夜间货运”
