很蛋疼的三个问题。
最近在通达oa上做二次开发。遇到了三点很蛋疼的问题。希望各位大神能给提提宝贵的意见

1:同样的代码。我在wamp环境里 用管理员创建成功了普通用户后,右上角的登陆用户依然是管理员。但是放到oa里右上角就是刚刚添加成功的这个用户。并且其他功能点击的时候会显示我做好了的非法访问页面,但是继续添加用户,居然可以(我也是做了同样的非法访问,并没有去执行)

2:用户  管理员  供货商三个页面。都有刷新订单功能。  同样的写法。  管理员和用户的刷新 不管刷新几次。 都没有问题。 但是供货商的  期初刷新一次,能显示正常订单数,但是刷新第二次,数据库直接没有了。

3:用ajax做 一个快速搜索客户的联动功能。编码全部一致,并且 echo了一下sql语句 也没有乱码。但是右边的下拉表明显动了一下,但是不跟随sql语句得到的答案进行选中。

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.
