更改个人资料图片上传名称？
Changing Profile Picture upload name?
我需要一些帮助，我正在尝试在有人上传图片后将其更改为他们的用户名。这是我拥有的一些 PHP 脚本，它通过文件原来的名称上传图像。
所以一旦他们登录，它会自动显示他们的用户名，我用过
$_SESSION['username'] 我该如何使用它，一旦他们选择了一张照片，它就会将其保存为他们的用户名。示例：我正在上传一个名为 logo.png 的文件，我的用户名是 admin。我该怎么做才能将文件名更改为 admin.png 而不是 logo.png？
<pre>//if not logged in redirect to login page
if(!$user->is_logged_in()){ header('Location: login.php'); }
?>
<?php
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
$check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
if($check !== false) {
echo "File is an image - " . $check["mime"] . ".";
$uploadOk = 1;
} else {
echo "File is not an image.";
$uploadOk = 0;
}
}
// Check if file already exists
if (file_exists($target_file)) {
echo "Sorry, file already exists.";
$uploadOk = 0;
}
// Check file size
if ($_FILES["fileToUpload"]["size"] > 500000) {
echo "Sorry, your file is too large.";
$uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
$uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
} else {
echo "Sorry, there was an error uploading your file.";
}
}
?>

嘿，我想你只需要改变你的 $target_file 变量...试试这样：
.....
$target_file = basename($_FILES["fileToUpload"]["name"]);
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION); //IMAGE FILE TYPE
$fileName = $_SESSION['username'].'.'. $imageFileType; //GENERATE FILE NAME
....//then when you move the file
move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_dir.$fileName)
如您所见，我将 $target_file 更改为 $fileName 并添加了 $target_dir
比应该还可以！
