Thinking

For When different users upload avatars, we need to create a folder for each logged-in user. The name of the folder is based on the username of the current user.

After the user uploads successfully, jump to the page after the user successfully logs in, and refresh the user's avatar.

Login page

Verification page

Since the core of this experiment is to change the user’s avatar, we will not care about the user name for the time being, and the Root will prevail.

Verification logic

3秒后将自动跳转到个人主页！"; $_SESSION['username'] = $username; header("refresh:3;url=./personalpage.php"); }else{ echo "对不起，登陆失败了！"; header("refresh:3;url=./index.php"); //echo ""; }

Copy after login

##Page jump

In PHP, there are many ways to jump to the page first. This article uses the method of adding header information. Here are a few small examples of page jumps.

header function

< ?php //重定向浏览器 header("Location: http://blog.csdn.net/marksinoberg"); //确保重定向后，后续代码不会被执行 exit; ?>

Meta tag

Copy after login

Note: content can be controlled to complete the jump within a few seconds change.

JavaScript

< ?php $ url = "http://bbs.lampbrother.net" ; echo " < script language = 'javascript' type = 'text/javascript' > "; echo " window.location.href = '$url' "; echo " < /script > "; ?>

Copy after login

Note: Using JavaScript, the code can be placed anywhere you like , as long as it meets the grammatical requirements.

Upload page

Personal homepage

    <?php session_start(); echo $_SESSION['username']."的个人主页"; ?>

Upload core

The core of upload is still a form. We upload the image to be uploaded to the server, and then PHP uses move_uploaded_file to implement file migration. , to achieve uploading.

0) { die("出错了！".$_FILES['photo']['error']); } if(move_uploaded_file($_FILES['photo']['tmp_name'],$server_name)){ //echo "
"."Upload Success!"; echo "恭喜您，上传成功！"."
3秒后将自动跳转到个人主页！"; header("refresh:3;url=./personalpage.php"); }else{ //echo "
"."Upload Failed!".$_FILES['photo']['error']; echo "对不起，上传头像失败了！"; header("refresh:2;url=./index.php"); } ?>
