图片以路径方式存入数据库 数据库设计 以及在页面中显示 急急急 !


if (is_uploaded_file($_FILES['upfile']['tmp_name'])){

$upfile=$_FILES["upfile"];

$name = $upfile["name"];
$type = $upfile["type"];
$size = $upfile["size"];
$tmp_name = $upfile["tmp_name"];
$error = $upfile["error"];


switch ($type) {
case 'image/pjpeg' : $ok=1;
break;
case 'image/jpeg' : $ok=1;
break;
case 'image/gif' : $ok=1;
break;
case 'image/png' : $ok=1;
break;
}

if($ok && $error=='0'){
 move_uploaded_file($tmp_name,'up/'.$name);
 echo "上传成功";
 echo "$name.
";
 echo "$type.
";
 echo "$size.
";
 echo "$tmp_name.
";
 
}
}

非常急 帮忙直接给改写代码吧!
这是一个头像上传 数据库为 zuoye 表 user 表中字段 id username name age email  
这个图片该怎么存到数据库 怎样设计数据库 求解释

------解决方案--------------------
'up/'.$name是你的文件地址。
没必要保存,因为文件地址= 'up/'.$name
------解决方案--------------------
看了一下,像上面说的 不需要保存路径到数据库吧?你的路径就是 up 文件夹而已.所以可以保存文件名到数据库.

数据库增加一个img 的字符型字段,长度为 50.

代码大约如此

PHP code

// 需要传递用户名,或者上传者的用户ID,可以用session来控制,看你的登录代码怎么写
// 假设为session 如果是GET id 请自行修改其他页面传递id  并且做赋值
session_start ();
// 赋值变量
$Uid = $_SESSION ['UserId'];
if (is_uploaded_file ( $_FILES ['upfile'] ['tmp_name'] )) {
    
    $upfile = $_FILES ["upfile"];
    
    $name = $upfile ["name"];
    $type = $upfile ["type"];
    $size = $upfile ["size"];
    $tmp_name = $upfile ["tmp_name"];
    $error = $upfile ["error"];
    
    switch ($type) {
        case 'image/pjpeg' :
            $ok = 1;
            break;
        case 'image/jpeg' :
            $ok = 1;
            break;
        case 'image/gif' :
            $ok = 1;
            break;
        case 'image/png' :
            $ok = 1;
            break;
    }
    
    if ($ok && $error == '0') {
        move_uploaded_file ( $tmp_name, 'up/' . $name );
        // 将文件名保存到数据库
        // 数据库链接部分,自行修正完整
        mysql_connect ();
        //更新数据库字段img 查询条件 用户id
        $SQL = "UPDATE  zuoye SET `img`='{$name}' WHERE `id`='{$Uid}'";
        mysql_query ( $SQL );
        if (mysql_affected_rows () > 0) {
            echo "上传头像数据更新成功";
            echo "$name.<br>";
            echo "$type.<br>";
            echo "$size.<br>";
            echo "$tmp_name.<br>";
        } else {
            echo '数据更新失败';
        }
    
    }
} <div class="clear">

Session regeneration refers to generating a new session ID and invalidating the old ID when the user performs sensitive operations in case of session fixed attacks. The implementation steps include: 1. Detect sensitive operations, 2. Generate new session ID, 3. Destroy old session ID, 4. Update user-side session information.

PHP sessions have a significant impact on application performance. Optimization methods include: 1. Use a database to store session data to improve response speed; 2. Reduce the use of session data and only store necessary information; 3. Use a non-blocking session processor to improve concurrency capabilities; 4. Adjust the session expiration time to balance user experience and server burden; 5. Use persistent sessions to reduce the number of data read and write times.

What are some best practices for securing PHP sessions?What are some best practices for securing PHP sessions?May 01, 2025 am 12:22 AM

The security of PHP sessions can be achieved through the following measures: 1. Use session_regenerate_id() to regenerate the session ID when the user logs in or is an important operation. 2. Encrypt the transmission session ID through the HTTPS protocol. 3. Use session_save_path() to specify the secure directory to store session data and set permissions correctly.
