Answer 1

我假设您的数据库中已经有学生并更改了他们的个人资料图片

用户必须登录才能上传图片，因此您将使用类似 $_SESSION['studentid'] 的内容

<?php
$path = "upload/" . $_FILES["file"]["name"];
move_uploaded_file($_FILES["file"]["tmp_name"],$path);

$sql = "UPDATE students SET image = '".$path."' WHERE id = ".$_SESSION['studentid'];
mysql_query($sql) OR die(mysql_error());

?>

稍后，如果您想显示用户图像，请使用此查询

<?php

$sql = "SELECT image FROM students WHERE id = ".$_SESSION['studentid'];
$result = mysql_query($sql) OR die(mysql_error());
$row = mysql_fetch_assoc($result);

echo $row['image'];
?>
