            " />启用
            " />停用

控制层那边传到页面是status 里面 1是启用 2是停用,如果控制层传过来是1 那么就选中启用相反,控制层传过来是2 那么就是停用。


 我上面写的没有效果,求大虾指点

<input type="radio" name="status" <?php if($status==1){ ?> checked="checked" <?php } ?> id="status" value="<?php if(isset($status)){ echo($status);} ?>" />启用<input type="radio" name="status" id="status"  <?php if($status==2){?> checked="checked" <?php } ?> value="<?php if(isset($status)){ echo($status);} ?>" />停用
Copy after login
Copy after login

选不选中,应该设置checked 属性的值。

<input type="radio" name="status" <?php if($status==1){ ?> checked="checked" <?php } ?> id="status" value="<?php if(isset($status)){ echo($status);} ?>" />启用<input type="radio" name="status" id="status"  <?php if($status==2){?> checked="checked" <?php } ?> value="<?php if(isset($status)){ echo($status);} ?>" />停用
Copy after login

A PHP Error was encountered

Severity: Notice

Message: Undefined variable: status

Filename: test/testadd.php

Line Number: 62

如果$status为空的时候 怎么会报错,怎么判断一下为空就谁都不选择

我在做一个增加 修改 都同一个页面

<input type="radio" name="status" id="status" value="1" <?php if(isset($status) && $status==1){ echo "checked='checked'";} ?> />启用            <input type="radio" name="status" id="status" value="2" <?php if(isset($status) && $status==2){ echo "checked='checked'";} ?> />停用
Copy after login

在模板里写php可以这样写

if (true) /**这里写代码*/endif;
Copy after login
Copy after login


要不看到都是大括号,很不好看。。。

写错了,应该这样:
if (true): /**这里写代码*/endif;
Copy after login

选不选中,应该设置checked 属性的值。





不好意思  分给错人了,下次多给你一点,大虾

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,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

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.
