HomeBackend DevelopmentPHP Tutorial怎么把cookie自动填进表单啊?

Cookie 登录

每次登陆的时候有cookie的话就把cookie自动填进表单,停在登录页面,怎么搞,我只能直接跳转

回复讨论(解决方案)

Cookie自动带过去的用不着手动写入表单,如果实在想写就用js搞下

<?php                if(empty($_COOKIE["username"]))        {           $_COOKIE["username"]="kobe_chen" ;        }                    if($_SERVER["REQUEST_METHOD"]=="GET")            {?>                <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST">                    <input type="text" name="username" id="username" value="<?php echo $_COOKIE["username"] ?>" />                    <input type="submit" name="btnSubmit" id="btnSubmit" value="提交" />                </form>            <?php            }?>

停在登录页面 ? 不让登陆吗

意思是,不要自动跳转,用户名和密码已经填好,让用户点登录键。。。

js和PHP都可以实现这个功能,Easy

若果用php的话都是像2楼一样么》?

这个功能用php也容易实现
我们现在登录页面设置一个勾选框,如果勾选,就说明保存用户名
首先我们在前台页面这样写


   
     
     
     
     
   
用户id "
密码
是否保存用户id



后台程序loginProcess.php

if(!empty($keep)){
setcookie('id',$id,time()+3600*24*30);


}else{
if(!empty($_COOKIE['id'])){
setcookie('id',$id,time()-100);
}
}
即可。具体可以看传智播客php视频教程第114讲cookie。就讲到了这个用法。

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
