我有一个人们可以上传单个图片的表单。大多数人都是从他们的移动设备上传图片。每个拥有iPhone的人都将其图片上传为“image.png”。我需要让我的表单不要拒绝它，并且只接受具有相同名称的文件而不删除旧文件，或者将它们重命名为“imageupload1.png”，“imageupload2.png”或甚至是image.png然后“image-Copy”。 png“then”image-Copy（2）.png“等等
我觉得这样的事情可能有用：
$filename = $_FILES['myfilename']['name'];
$filename = time().$filename;
或
function renameDuplicates($path, $file)
{
$fileName = pathinfo($path . $file, PATHINFO_FILENAME);
$fileExtension = "." . pathinfo($path . $file, PATHINFO_EXTENSION);
$returnValue = $fileName . $fileExtension;
$copy = 1;
while(file_exists($path . $returnValue))
{
$returnValue = $fileName . '-copy-'. $copy . $fileExtension;
$copy++;
}
return $returnValue;
}
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
$check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
if($check !== false) {
echo "Sucessfully Uploaded - " . $check["mime"] . ".";
$uploadOk = 1;
} else {
echo "File is not an image.";
$uploadOk = 0;
}
}
我只是不知道在哪里插上它。我是一个菜鸟所以请放轻松我，请具体。我认为可能有用的选项取自其他问题，但它们对我不起作用，很可能我做错了所以请不要将其标记为“已经问过”谢谢。很抱歉打扰了。

代替您的$target_file定义，插入重复数据删除功能：
$target_file = renameDuplicates($target_dir, basename($_FILES["fileToUpload"]["name"]));
（我没有检查功能是否正常，但乍一看它应该没问题。）
编辑：功能有点破碎。function renameDuplicates($path, $file) {
$fileName = pathinfo($path . $file, PATHINFO_FILENAME);
$fileExtension = "." . pathinfo($path . $file, PATHINFO_EXTENSION);
$returnValue = $path . $fileName . $fileExtension;
$copy = 1;
while(file_exists($returnValue))
{
$returnValue = $path . $fileName . '-copy-'. $copy . $fileExtension;
$copy++;
}
return $returnValue;
}
检查包含$returnValue的行是否有更改。

我来救你，并为你写了整篇文章：）
您需要具备以下结构：
upload.php
ImageUpload/uploadMe.php
：
<html>
<head>
<title>Upload Your image here | SiteName</title>
<!-- Latest compiled and minified Bootstrap CSS -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">
</head>
<body>
<div class="container">
<div class="row">
<?php
$FLAG = $_GET['e'];
if($FLAG == "UPLOAD_FAILED"){ ?>
<div class="col-md-12 alert alert-warning">
Ooops! It looks like an error occured when uploading your image.
</div>
<?php } else if($FLAG == "NOT_IMAGE"){ ?>
<div class="col-md-12 alert alert-warning">
Hey! Thats not an image?<br/>
<pre>We only allow: png, jpg, gif and jpeg images.</pre>
</div>
<?php } else{} ?>
<div class="well col-md-6">
<form action="ImageUpload/uploadMe.php" method="POST" enctype="multipart/form-data">
<legend>
Image Upload
</legend>
<input type="file" name="file" class="form-control btn btn-info"/>
<br/>
<input type="submit" value="Upload" class="btn btn-primary"/>
</form>
</div>
<div class="well col-md-6">
<p><h1>Step 1</h1><br>
Please submit a recent photograph to be featured on the homepage of this website.<br><br>

<br>This will allow our classmates to see how we look now and how we looked then.<br><br>

在ImageUpload / uploadMe.php中：
<?php
if(isset($_FILES['file'])){
$File = $_FILES['file'];
//File properties:
$FileName = $File['name'];
$TmpLocation = $File['tmp_name'];
$FileSize = $File['size'];
$FileError = $File['error'];
//Figure out what kind of file this is:
$FileExt = explode('.', $FileName);
$FileExt = strtolower(end($FileExt));
//Allowed files:
$Allowed = array('jpg', 'png', 'gif', 'jpeg');
//Check if file is allowed:
if(in_array($FileExt, $Allowed)){
//Does it return an error ?
//No:
if($FileError==0){
$ImageFolder = "uploads";
//Check if exist, otherwise create it!
if (!is_dir($ImageFolder)) {
mkdir($ImageFolder, 0777, true);
}
else{}
//Create new filename:
$NewName = uniqid('', true) . rand(123456789,987654321). '.' . $FileExt;
$UploadDestination = $ImageFolder ."/". $NewName;
//Move file to location:
if(move_uploaded_file($TmpLocation, $UploadDestination)){
//Yay! Image was uploaded!
//Do whatever you want here!
}
//File didnt upload:
else{
//Redirect:
header("Location: /upload.php?e=UPLOAD_FAILED");
}
}
//An error occured ?
else{
//Redirect:
header("Location: /upload.php?e=UPLOAD_FAILED");
}
}
//Filetype not allowed!
else{
//redirect:
header("Location: /upload.php?e=NOT_IMAGE");
}
}
else{
//No file was submitted :s send them back, eh ?
header("Location: /upload.php");
}
好的，我认为现在已经完成了！
如果您想使用自己的“外观”，只需复制并粘贴<form></form>内容，也许是简单的“错误”处理程序？
有一个好的：）

<input class="uploadGAConnection" #uploadFile type="file" (change)="uploadGAConnectionDetails($event)" placeholder="Upload file" accept=".csv,.json" (click)="uploadFile.value=null">
您只需提供参考并将每次点击的值设置为null。
