Question

我创建了一个HTML表单，允许我将图像上传到唯一命名的目录（即日期/时间/ IP地址的组合）。现在我试图上传两张图片（最终是多张）。我已经复制了我的文件1＆＃34;内容并将其唯一地命名为＆＃34;文件2＆＃34;。我很快就附上了一个＆＃34; 2＆＃34;到每个变量和后期字段。这是我的上传表单HTML：

<!DOCTYPE html>
<html>
<body>

<form action="icanhazuploads.php" method="post" enctype="multipart/form-data">
Select image(s) to upload: <br /><br />
<input type="file" name="fileToUpload" class="fileToUpload"><br /><br />
<input type="file" name="fileToUpload2" class="fileToUpload2"><br /><br />
<input type="submit" name="submit">
</form>

</body>
</html>

非常直接。两个上传字段和一个提交按钮。这是我的PHP处理器文件：

<?php
// Display Errors
ini_set('display_errors', 'On');
ini_set('html_errors', 0);

$ip = ip2long($_SERVER['REMOTE_ADDR']);
$datetime = date('YmdHis');  
$target_dir = "uploads/" . $datetime . $ip . "/";

// Create the unique diretory
if (!file_exists($target_dir)) {
    mkdir($target_dir, 0777, true);
}

// Start processing files

// File 1
echo "<br />1st file being added...<br />";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
echo "<br />Target File: " . $target_file. "<br />";
$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"] . ".<br />";
        $uploadOk = 1;
    } else {
        echo "File is not an image.<br />";
        $uploadOk = 0;
    }
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
    echo "Your file was not uploaded.<br />";
// 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.<br />";
    } else {
        echo "There was an error uploading your file.<br />";
    }
}



// File 2
if(isset($_POST["fileToUpload2"])) {
echo "<br />2nd file being added...<br />";
$target_file2 = $target_dir . basename($_FILES["fileToUpload2"]["name"]);
echo "<br />Target File: " . $target_file2. "<br />";
$uploadOk = 1;
$imageFileType = pathinfo($target_file2,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["fileToUpload2"]["tmp_name"]);
    if($check !== false) {
        echo "File is an image - " . $check["mime"] . ".<br />";
        $uploadOk = 1;
    } else {
        echo "File is not an image.<br />";
        $uploadOk = 0;
    }
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
    echo "Your file was not uploaded.<br />";
// if everything is ok, try to upload file
} else {
    if (move_uploaded_file($_FILES["fileToUpload2"]["tmp_name"], $target_file2)) {
        echo "The file ". basename( $_FILES["fileToUpload2"]["name"]). " has been uploaded.<br />";
    } else {
        echo "There was an error uploading your file.<br />";
    }
}

真的很神奇。我在浏览器中提取我的HTML表单，选择两个图像并点击提交。我可以使用Firebug或Chrome的检查员观看，并通过POST填充两个图像字段来查看它。但是，我的PHP文件将始终只能看到一个。如果我只将我的图像放在表单的第二个字段中，它仍然就像我将它放在第一个字段中一样。错误日志中没有错误。知道为什么它拒绝看到多个文件吗？

我的php.ini设置：

; Maximum allowed size for uploaded files.
; http://php.net/upload-max-filesize
upload_max_filesize = 64M

; Maximum number of files that can be uploaded via a single request
max_file_uploads = 20

Answer 1

if(isset($_POST["fileToUpload2"])) {

这是错的，它永远不会被设置。

尝试

if(isset($_FILES["fileToUpload2"])) {

为了将来的调试，请使用var_dump($_POST);和var_dump($_FILES);，您将立即看到正在发生的事情

PHP：同时上传多个图像
