我想将文件上传到指定的文件夹。
<?php
$folder = "upload/";
if (is_uploaded_file($HTTP_POST_FILES['filename']['tmp_name'])) {
if (move_uploaded_file($HTTP_POST_FILES['filename']['tmp_name'], $folder.$HTTP_POST_FILES['filename']['name'])) {
echo "File uploaded";
} else {
echo "File not moved to destination folder. Check permissions";
};
} else {s
echo "File is not uploaded";
};
?>
错误是：
注意：未定义的变量：第3行的C：\ wamp \ www \ sdg \ import \ ips.php中的HTTP_POST_FILES

以下是上传文件的一种方法，还有很多方法。
正如@nordenheim所说，自PHP 4.1.0以来，$HTTP_POST_FILES已被弃用，因此不建议使用它。
PHP代码（upload.php）
<?php
$target_dir = "upload/";
$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($_POST["submit"])) {
if ($target_file == "upload/") {
$msg = "cannot be empty";
$uploadOk = 0;
} // Check if file already exists
else if (file_exists($target_file)) {
$msg = "Sorry, file already exists.";
$uploadOk = 0;
} // Check file size
else if ($_FILES["fileToUpload"]["size"] > 5000000) {
$msg = "Sorry, your file is too large.";
$uploadOk = 0;
} // Check if $uploadOk is set to 0 by an error
else if ($uploadOk == 0) {
$msg = "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
$msg = "The file " . basename($_FILES["fileToUpload"]["name"]) . " has been uploaded.";
}
}
}
?>
启动功能的HTML代码
<form action="upload.php" method="post" id="myForm" enctype="multipart/form-data">
Select file to upload:
<input type="file" name="fileToUpload" id="fileToUpload">
<button name="submit" class="btn btn-primary" type="submit" value="submit">Upload File</button>
</form>
希望这有帮助。

PHP 4.1引入了superglobals。它们替换了包含从请求中提取的数据的旧的，长命名的数组。已将$_FILES[]替换为$HTTP_POST_FILES[]，将$_GET[]替换为$HTTP_GET_VARS[]，依此类推
对于后续的PHP 4版本，旧的和新的阵列可以并排使用。默认情况下，PHP 5禁用了旧数组的生成，并引入了可用于重新启用旧数组创建的php.ini directive register_long_arrays。
自PHP 5.4起，旧的长名称数组被完全删除，register_long_arrays与它们一起被移除。
结论：您正在从一个非常古老或非常糟糕的教程中学习。找一个更好的。

首先，编写这样的html代码，不要忘记添加enctype="multipart/form-data"
<form action="upload.php" method="post" enctype="multipart/form-data">
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload Image" name="submit">
</form>
然后创建一个名为upload.php的文件名
<?php
$path = "form/";
$target_file = $path.basename($_FILES["fileToUpload"]["name"]);
$file=$_FILES['fileToUpload']['name'];
$result = move_uploaded_file($_FILES['fileToUpload']['tmp_name'],$target_file.$file);
if ($result) {
echo "file successfully uploaded";
}
else {
echo "please select your file";
}

您应该尝试
$fileType = $_FILES['profileimage']['type'];
$fileName = $_FILES['profileimage']['name'];
$array = explode(".", $fileName);
$ext = $array[count($array)-1];
$imageAutoName = "profileimagehr".$rsinssupp.".".$ext;
if(!move_uploaded_file($_FILES['profileimage']['tmp_name'],'img/user/'.$imageAutoName))
{
$msg = "";
}
else
{
$iquery = "UPDATE tblname SET filane = '".$imageAutoName."' WHERE id = ".$rsinssupp."";
$obj->edit($iquery);
}
