php怎么实现用户登陆以后让用户id供所有导航栏中跳转页面
问题大概是这样的:当用户A登陆以后,会先跳转到首页,
首页传参数是这样的,可是如果要连接到导航栏里的其他版块怎么办?怎么就只传一次,满足所有的跳转

不是很明白需求,暂且理解为,参数怎么在不同链接和页面直接传递。
方法
- 在php输出的时候把参数写到各个导航栏链接里。
- 存在session或cookie里,在导航栏里的模块要用的时候去读取。
- 通过js的方式,动态给指定的链接添加参数
建议
- 保持良好的URL结构很重要,要是我宁愿在后端通过session去查询用户需要的相关参数。
- 不要滥用cookie,项目大了,一看到这些乱七八糟的key,头会很大的。
- 最终建议,如果用户相关系比较强,放session,反之通过代码封装来查询。
装在session里,然后再在前端读。
