我需要在我的网站上创建一个上传页面，我正在使用 altervista 试用服务器。
我使用了教程http://www.w3schools.com/php/php_file_upload.asp http://www.w3schools.com/php/php_file_upload.asp但上传不起作用。也许，正如我读到的那样，这是一个权限问题，但我对如何更改文件夹的权限一无所知。
是否可以在可上传文件中添加 pdf？
thanks
上传页面.html
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Documento senza titolo</title>
<link href="valsilehome.css" rel="stylesheet" type="text/css">
</head>
<body>
<form action="/tmp/upload.php" method="post" enctype="multipart/form-data">
Select image to upload:
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload Image" name="submit">
</form>
</body>
</html>
上传.php
<?php
$target_dir = "/tmp/uploads";
$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"])) {
$check = getimagesize($_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;
}
// 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( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
} else {
echo "Sorry, there was an error uploading your file.";
}
}
?>
从w3学校来说，他们为例子创造了很多条件。但我们不需要严格遵守。我们只有在需要时才可以使用它。
这是您可以拥有的最少代码
<!DOCTYPE html>
<html>
<body>
<form action="" method="post" enctype="multipart/form-data">
Select image to upload:
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload Image" name="submit">
</form>
</body>
</html>
<?php
if (isset($_POST['submit']))
{
echo 'succesfully uploaded';
$structure = 'uploadedfiles/';
$target_file = $structure.basename($_FILES["fileToUpload"]["name"]);
move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file);
}
?>
如果您使用上面的代码，您应该创建一个名为的文件夹uploadedfiles在保存此文件的文件夹中。
否则，如果您需要为每个文件上传创建每个文件夹，那么您应该编码..它每次都会将文件的名称创建为文件夹。
<!DOCTYPE html>
<html>
<body>
<form action="" method="post" enctype="multipart/form-data">
Select image to upload:
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload Image" name="submit">
</form>
</body>
</html>
<?php
if (isset($_POST['submit']))
{
echo 'succesfully uploaded';
$structure = $_FILES["fileToUpload"]["name"];
if (!mkdir($structure, 777, true))
{}
$target_file = $structure.basename($_FILES["fileToUpload"]["name"]);
move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file);
}
?>
