网站后台用户权限设计问题
如下图所示
左边是后台的导航,右边是用户的状态(只读,可写)
现在的需求是给用户分配权限,问题出来了
添加用户的时候,如何把复选框的值跟前面的导航的id 一起传过去呢?
就像这样 导航id,read,edit 对应数据库是"0,0,1" ,"1,0,1","2,0,1"...
如果复选框之选一个 ,对应数据库就只有一个导航id号+复选框选中的value 如(0,0)or (0,1)...
如果 一个都不选 ,数据库就只有一个导航id
该如何设计插入呢?
------解决方案--------------------
你这个要先在js进行处理。发一个字符串(0100)到php那边 再到php那进行处理,打包成你想要的格式
我以四个复选框为例 html+js部分的
<script><br /> function mySubmit(){<br /> checkboxes = document.getElementsByName("a");<br /> var str="";<br /> for(i=0;i<checkboxes.length;i++){<br /> if(checkboxes[i].checked==true){<br /> str +="1";<br /> }else{<br /> str +="0";<br /> }<br /> }<br /> <span style="max-width:90%">//比如选了2 3 那么就是 0110<br /> addFrom.action +="?str="+str;<br /> addFrom.submit();<br /> } <br /></script>

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.

Sending mail using PHP and SMTP can be achieved through the PHPMailer library. 1) Install and configure PHPMailer, 2) Set SMTP server details, 3) Define the email content, 4) Send emails and handle errors. Use this method to ensure the reliability and security of emails.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
