Php 根据查询结果隐藏DIV或按钮
我试图根据会话中存储的值隐藏一个DIV或相关按钮（该会话在登录时收集用户数据）。例如，如果有人使用20的访问代码登录，我希望某些按钮被禁用、隐藏等。这是一个内部门户，初学者可以使用它，所以我觉得很简单。任何其他想法都是非常受欢迎的。我该怎么做 这是我目前的代码。我已经删除了帖子的样式属性。谢谢大家Php 根据查询结果隐藏DIV或按钮,php,sql,Php,Sql,我试图根据会话中存储的值隐藏一个DIV或相关按钮（该会话在登录时收集用户数据）。例如，如果有人使用20的访问代码登录，我希望某些按钮被禁用、隐藏等。这是一个内部门户，初学者可以使用它，所以我觉得很简单。任何其他想法都是非常受欢迎的。我该怎么做 这是我目前的代码。我已经删除了帖子的样式属性。谢谢大家 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/x

MK钻石-主菜单
仅仅因为人们年纪大了，并不意味着他们不知道如何进入开发工具和取消隐藏/取消禁用按钮。。。如果（$row[acctype]==20）{echo”“；}开头。看看语法，它会使您的代码更整洁。无论这是做什么包括（“session.php”）
在将任何内容输出到呈现文档之前（即，如果它包含会话\u start（）
），它应该放在脚本的最顶端。
