Question

我需要一些帮助，我试图在有人上传图片后将其更改为用户名。这是我的一些PHP脚本，它按照文件原来的名称上传图像。

因此，一旦他们登录，它会自动显示他们使用的用户名 $ _SESSION ['username']我如何使用它，所以一旦他们选择了照片，它会将其保存为用户名。示例：我正在上传名为logo.png的文件，我的用户名是admin。如何将文件名更改为admin.png而不是logo.png？

//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

比应该没问题！
