【问题描述】:
我希望文件名是用户的用户名,而不是用户想要命名的文件名。正如您在下面的代码中看到的,我从会话中获取了用户的用户名。现在,我只想将它应用到 $_FILES,但是用 $username 替换 $_FILES["fileToUpload"]["name"] 并没有发生。我不确定我做错了什么,所以我把它改回来了。请看一下。
上传.php
<?php
include("functions.php");
session_start();
$username = $_SESSION['username'];
$target_dir = "uploads/";
$target_file = $target_dir . $_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.";
goTo("home.php");
} else {
echo "Sorry, there was an error uploading your file.";
}
}
?>
【问题讨论】:
-
你应该可以设置
$target_file = $target_dir . $username;。除了文件名之外,代码是否按您的预期工作?如果没有,可能还有其他问题。 -
从你的代码中获取这个:$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);在末尾添加一个扩展
