基本上，当用户在我的表单上上传文件时，我不会在docs文件夹内创建一个新文件夹，然后在该文件夹内放置他们上传的文档。
例如：
主文件夹= docs /
如果用户上传文档，我希望它看起来像这样：
docs / 1 / document.jpg
因此，它在docs文件夹中创建了文件夹1并将其放入。但是到目前为止，我的代码正确地在docs文件夹中创建了文件夹1。但是实际文档并没有进入1文件夹，而是进入了根目录。
我的代码的结果
文件/ 1
document.jpg
它不在docs文件中，而是在实际的根目录中。
代码：
<?php
$number = 1;
$target_dir = "docs/";
$target_file = mkdir($target_dir . $number . "/") . basename($_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.";
$uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
$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.";
}
}
?>
更改此：
$target_dir = "docs/";
$target_file = mkdir($target_dir . $number . "/") . basename($_FILES["fileToUpload"]["name"]);
对此
$target_dir = "docs/";
mkdir($target_dir . $number . "/");
$target_file = $target_dir . $number . "/" . basename($_FILES["fileToUpload"]["name"]);
mkdir 返回值是一个布尔值。
