我正在尝试将图像上传到服务器，代码工作正常，提交按钮文件正确上传并提供正确的输出。 如下
腓
<?php
//header('Content-type: application/json');
// Upload and Rename File
include 'reqFunctions.php';
$timestamp1=time();
$uploadDir="C:/test/";
$userId=20;
$userFolder=null;
$userId=$_POST["userId"];
echo "user id is " .$userId;
$userFolder=md5($userId);
$newUploadDir=$uploadDir."/".$userFolder."/profile/";
//if(isLogin()==false){
foreach($_FILES as $value){
$filename = $value["name"];
echo "file name ".$filename;
$file_basename = substr($filename, 0, strripos($filename, '.')); // get file extention
$file_ext = substr($filename, strripos($filename, '.')); // get file name
$filesize = $_FILES["file"]["size"];
echo "file detail is ".$filename."<br>";
echo "file extension is ".$file_ext."<br>";
echo "file size is ".$filesize."<br>";
$allowed_file_types = array('.jpg','.gif','.mpeg');
if (in_array($file_ext,$allowed_file_types) && ($filesize < 20000000)){
if (!file_exists($uploadDir."/".$userFolder)) {
mkdir($uploadDir."/".$userFolder, 0777, true);
}
if (!file_exists($uploadDir."/".$userFolder."/profile")) {
mkdir($uploadDir."/".$userFolder."/profile", 0777, true);
}
$newfilename=generateRandomString(10)."_".$timestamp1."_".generateRandomString(10).$file_ext;
//echo "new file name is ".$newfilename."<br>";
if (file_exists($newUploadDir. $newfilename))
{
// file already exists error
//echo "You have already uploaded this file.<br>";
}
else
{
move_uploaded_file($_FILES["file"]["tmp_name"], $newUploadDir. $newfilename);
//echo "File uploaded successfully. <br>";
}
}
elseif (empty($file_basename))
{
// file selection error
//echo "Please select a file to upload.<br>";
}
elseif ($filesize > 20000000)
{
// file size error
//echo "The file you are trying to upload is too large.";
}
else
{
// file type error
//echo "Only these file typs are allowed for upload: " . implode(', ',$allowed_file_types);
unlink($_FILES["file"]["tmp_name"]);
}
$path= $newUploadDir. $newfilename;
}
echo ($path);
//echo(json_encode($path));
/*}else{
echo(json_encode("Please login"));
}*/
?>
html文件
<form action="fileUpload2.php" enctype="multipart/form-data" method="post">
<input id="file" name="file" type="file" />
<input id="file" name="userId" type="text" value="2"/>
<input id="Submit" name="submit" type="submit" value="Submit" />
</form>
以上代码正常运作
现在我用
更改了html代码<form action="#" class="dropzone" method="post"></form>
<script>
$(".dropzone").dropzone({
paramName: "file",
maxFilesize: 20,
url: 'fileUpload2.php',
uploadMultiple: true,
parallelUploads: 5,
dataType: 'json',
maxFiles: 10,
acceptedFiles: "image/*,audio/*,video/*",
init: function () {
this.on('sending', function(file, xhr, formData){
formData.append('userId', 155);
});
this.on("success", function (file, responseText) {
console.log("l path " + responseText);
console.log(file);
console.log("---------------------------------");
});
}
});
</script>
不在服务器上传图像 在控制台上显示
l path user id is 155

答案 0 :(得分：0)
那是因为文件名现在是：
$filename = $value["name"][0];
