调试将图片文件上传到文件夹
[英]Debugging uploading picture files into a folder
问题描述
I am following this tutorial: http://www.w3schools.com/php/php_file_upload.asp . 
我正在关注本教程： http : //www.w3schools.com/php/php_file_upload.asp 。 And I have copied and pasted the code for both the PHP and the HTML. 而且我已经复制并粘贴了PHP和HTML的代码。 And in a folder, I have upload.html , php.ini (with file_uploads = On ), upload.php and a folder called uploads where all the uploaded files are supposed to go in, I think. 我认为，在一个文件夹中，我有upload.html ， php.ini （带有file_uploads = On ）， upload.php和一个名为uploads的文件夹，应该将所有已上传的文件放入其中。
And when I press submit, everything seems to work, namely, the success message is echoed, "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded." 当我按Submit时，一切似乎都起作用，即成功消息回显为"The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded." "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded." . 。 However, no file seems to appear inside of the uploads folder. 但是， uploads文件夹内似乎没有文件。
Also, when I try to upload the same file, I get the error message, echo "Sorry, file already exists."; 另外，当我尝试上传相同的文件时，收到错误消息， echo "Sorry, file already exists."; , which is weird because I don't see the file in my uploads folder. ，这很奇怪，因为在我的uploads文件夹中看不到该文件。
I am currently using FireFTP to store all my code and the files that I am uploading. 我目前正在使用FireFTP存储我的所有代码和要上传的文件。
Here is my code for upload.html : 这是我的upload.html代码：
<!DOCTYPE html>
<html>
<body>
<form action="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>
And here is my upload.php : 这是我的upload.php ：
<?php
$target_dir = "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.";
$uploadOk = 0;
}
// Allow certain file formats
if($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.";
}
}
?>
Also, someone told me that PHP is a server side language. 另外，有人告诉我PHP是服务器端语言。 What does that actually mean? 这实际上是什么意思？ I tried to read some stuff online but its so full of so much jargon. 我试图在线阅读一些东西，但它充满了很多术语。 Does it mean that I have to use something like FireFTP to be able to use languages like PHP? 这是否意味着我必须使用FireFTP之类的东西才能使用PHP之类的语言？
And I can't just open up my textfile using chrome and be able to use PHP? 而且我不能只使用chrome打开文本文件并能够使用PHP？ Like, I right click my textfile containing my code and do "open with chrome"? 就像，我右键单击包含我的代码的文本文件，然后“用chrome打开”吗？ Does this also have to do with web-hosting? 这也与虚拟主机有关吗？

Try This Code 试试这个代码
$file_exts = array("jpg", "bmp", "jpeg", "gif", "png");
$file_exts = array("jpg", "bmp", "jpeg", "gif", "png");
$upload_exts = end(explode(".", $_FILES["fileToUpload"]["name"]));
if ((($_FILES["fileToUpload"]["type"] == "image/gif")
|| ($_FILES["fileToUpload"]["type"] == "image/jpeg")
|| ($_FILES["fileToUpload"]["type"] == "image/png")
|| ($_FILES["fileToUpload"]["type"] == "image/pjpeg"))
&& ($_FILES["fileToUpload"]["size"] < 2000000)
&& in_array($upload_exts, $file_exts))
{
if ($_FILES["fileToUpload"]["error"] > 0)
{
header("Location:dashboard.php?err=imgpro1");
//echo "Return Code: " . $_FILES["fileToUpload"]["error"] . "<br>";
}
else
{
$tempupname = time().$_FILES["fileToUpload"]["name"];
$imgpathtostore="uploads/".$tempupname;
$imgpathtostoreDB="uploads/".$tempupname;
// Enter your path to upload file here
move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $imgpathtostore);
}
}
else
{
header("Location: index.php?err=imgpro");
}
}

您需要将uploads文件夹权限设置为读取，写入和删除。
