php里面 button 怎么传值?

Jun 23, 2016 pm 02:17 PM

<input type="button" name="button" value="审核" style="width:80px; height:25px; cursor:pointer;" onMouseMove= "this.style.background= '#e1d4c7'" onMouseOut= "this.style.background= ''" onclick="window.location.href='gzd_manage_select_list.php?Gid=<?=$Gid;?>'" />
Copy after login

这个怎么传值onclick="window.location.href='gzd_manage_select_list.php?Gid='",onclick里面怎么把Gid=的只传到gzd_manage_select_list.php页面去啊,谢谢!

这不是已经传了吗?url带参数

echo $_GET['Gid'];

这不是已经传了吗?url带参数
没有啊,在gzd_manage_select_list.php页面没有得到值?

echo $_GET['Gid'];
这个是在gzd_manage_select_list.php页面写就会有值啦嘛,可是我这边却没有值啊?

当前页面 echo $Gid; 有值吗

<input type="button" name="button" value="审核" style="width:80px; height:25px; cursor:pointer;" onMouseMove= "this.style.background= '#e1d4c7'" onMouseOut= "this.style.background= ''" onclick="window.location.href='gzd_manage_select_list.php?Gid=<?echo $Gid;?>'" />
Copy after login



就是把'='改成'echo'

还是需要标签,用get或者post就可以了

gzd_manage_select_list.php 页面里写

if (!empty($_GET['Gid'])){     //如果 Gid 不为空  $Gid = $_GET['Gid'];         //设置变量$Gid 的值为传过来的Gid值  echo $Gid;                   //如果赋值成功,会有值输出}
Copy after login

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
