php 多选按钮取值或者去值
做一个php权限管理,要用多选按钮来做,比如:管理员要给一个普通的用户一个权限,就是给他可以看到什么或者可以在那个地方发表言论,这种应该怎么写代码?谢谢!
------解决方案--------------------
基础代码
$dict = array();<br /> if($_SERVER['REQUEST_METHOD'] == "POST") {<br /> echo array_sum($_POST['r']);<br /> $dict = $_POST['r'];<br /> }<br /> echo '<form method=post>';<br /> $right = array('读', '写', '修改', '删除');<br /> $a = 1;<br /> foreach($right as $k=>$v) {<br /> $t = $a << $k;<br /> $c = in_array($t, $dict) ? 'checked' : '';<br /> echo "<input type=checkbox name=r[] value=$t $c><br>";<br /> }<br /> echo '<input type=submit value=ok>';<br /> echo '</form>';<br />
------解决方案--------------------
基础代码已经给你了,
这时候你就要发挥你的思维,从理论到实际去实现
例如你每个管理权限给他
客户管理、合同管理、财务管理、工作单管理、基础管理
01110
0代表有权限控制
1代码无权限控制
写入数据库,然后读取的时候做比较。给出相应可执行权限。

你判断checkbox的 checked 属性不就行了
------解决方案--------------------
你输出checkbox的时候就可以判断了啊,参考版主的代码。

------解决方案--------------------
可以把权限列表和用来做判断的依据一一对应起来。
显示在页面的时候,根据值来做判断,来控制checkbox的checked属性就可以了。
------解决方案--------------------
#10写的很清楚了,你老强调自己是新手,如果你新到连html也不了解,那别人也无法帮你
自己在html里面写一下下面两句,看看区别就知道了

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.
