Php 会话不在多维数组上工作
我目前很难通过使用会话升级我的代码。这个案子是关于网络艺术的。我现在处于“添加到购物车”过程中。我想使用会话来保留用户选择的项目。但似乎每次我使用此会话时，都没有发生此操作。请帮我解决这个问题。顺便说一句，这是代码Php 会话不在多维数组上工作,php,arrays,session,multidimensional-array,associative-array,Php,Arrays,Session,Multidimensional Array,Associative Array,我目前很难通过使用会话升级我的代码。这个案子是关于网络艺术的。我现在处于“添加到购物车”过程中。我想使用会话来保留用户选择的项目。但似乎每次我使用此会话时，都没有发生此操作。请帮我解决这个问题。顺便说一句，这是代码 <?php session_start(); $q1=isset($_REQUEST['attack']) ? $_REQUEST['attack'] : 'no_value'; if(is_numeric($q1)){ $q1=number_

可能有以下原因
1） 无法在同一页面的同一请求上获取会话值
2） 如果您的服务器连接到路由器，那么您需要使用基于db的会话。您应该减少一些不相关的代码。Mattia Digora----比如？我对此做了研究，但它似乎不起作用。请帮助我有太多的代码，你应该减少它们。我们不想阅读每一行。好的。。我会减少这个。。
