Uploading files

Daggeth

I was reading the PHP.net documentation and it usually makes sense to me but File Uploading is another story...

I cant make any sense of Chapter 18. Handling file uploads.

If someone has better tutorial they know of, please point me to it.
Sample code will also do.. Basically my needs are as follows:
I need the file to be uploaded to a certain directory
I need the file's exact destination (http://www.yourserver.com/file.jpg)

If anyone knows of a tutorial that can help me, by all means point me to it.

well, when you upload a file via the post method, it's saved in a temp location.

To access it, use $HTTP_POST_FILES['getFileName']['tmp_name']

'getFileName' is the name of the field you gave which people use to browse for the files.

i.e. <input type="file" name="upFile">

thus $HTTP_POST_FILES['upFile']['tmp_name']

as you may notice, this is in the form of a multi-dimensional array, the second-level element in the array is 'tmp_name', there are other second-level elements :
'tmp_name' is the temporary name given to the file by PHP
'name' is the real name of the file... and so forth and so forth. you can find out more by searching the www.php.net site
search criteria HTTP_POST_FILES

then to save the file use this :

$fh = ''; // File handle set by fopen
$fh2 = ''; // File handle 2 set by second fopen
$fileBuffer = ''; // File buffer, the file info
$newFile = 'website/images/blah.jpg'; //new file

if ($fh = fopen( $HTTP_POST_FILES['upFile']['tmp_name'], 'r') ) {
$fileBuffer = fread( $fh, filesize( $HTTP_POST_FILES['upFile']['tmp_name'] ) );
fclose( $fh );
if ( $fh2 = fopen( $newFile, 'wb' ) ) {
fwrite( $fh2, $fileBuffer );
fclose( $fh2 );
} else {
echo 'could not create new file';
}
} else {
echo 'could not open uploaded file';
}

Just a couple things to add. In PHP 4.1.0 or later, $_FILES should be used instead of $HTTP_POST_FILES. http://www.php.net/manual/en/features.file-upload.php

Here's some sample code:

--form.php --

<form method="post" action="process.php" ENCTYPE="multipart/form-data">

File: <input type="file" name="upfile"><input type="submit" value="Upload">

</form>

-- end of form.php --

-- process.php --

<?

$upfile_name = $_FILES['upfile']['name'];

// set directory where you will be uploading (Make sure to 
// CHMOD to 777 
$dir = "../images";

// if no file was uploaded
if (($_FILES['upfile']['name'] == "")) {
   echo "No file Uploaded. Please go back and try again";
   exit;
}

// if a file with that name already exists on server
if (file_exists("$dir/$upfile_name")) {
   echo "A file with that name already exists on server. Please go back and try again";
} else {

// upload file
   if (is_uploaded_file($upfile)) {
      copy($_FILES['upfile']['tmp_name'], "$dir/$upfile_name");
      echo "File Uploaded Successfully";
   }

}

?>

You can use copy() or move_uploaded_file().

Don't forget to use enctype="multipart/form-data" in your form tag. If you don't, you won't have access to
$FILES['upfile']['name']
$FILES['upfile']['type'] etc.

I tried both of the codes you guys showed, plus another one I got off another site + one that was formulated by me, and the result for all was.. nothing.. The file still wont upload.. ive checked and double checked everything..

cgraz

Post your code. Things to check:

$dir = "../images";

Did you modify that to suit your needs. Do this. Where ever you have the upload scripts now, create a folder called uloads. CHMOD it to 777. Change $dir to

$dir = "uloads";

What version of PHP are you using? Does that version require you to use $_FILES['upfile'] or $HTTP_POST_FILES['upfile']. If you have register globals on, you could just use $upfile

Also after you upload, when you go to check if it uploaded (I suggest using an ftp program just cause it's visual), make sure to refresh the particular folder or the file won't appear in most ftp programs.

Also, my code outputs messages for different circumstances. The file won't upload doesn't tell us much. What did the script print?

I know your script tells what is happening but the problem is, its not saying anything at all. I changed what you asked me to change but nothing works.. Then I stripped the code down to the uploading part..

$upfile_name = $_FILES['upfile']['name'];
$dir = "Files";
      copy($_FILES['upfile']['tmp_name'], "$dir/$upfile_name");

The result I got:
Warning: Unable to open 'none' for reading: No such file or directory in /path/from/root/here/process.php on line 21

cgraz

Are you using the form i gave you? IT seems as if the file is set to none. My only guess would be to try changing $_FILES to HTTP_POST_VARS everywhere it occurs. For example:

$_FILES['upfile']['name'];
to

$HTTP_POST_VARS['upfile']['name']

Do you knwo what version of PHP you're using?

PHP Info Speaketh: 4.1.2

And changing to HTTP_POST_VARS is now giving the error: Unable to open '' for reading:

So your directory is named Files (capital F)? Have you CHMOD'd that directory to 777?? That's very important. Try this

<?

echo "UPFILE Name " . $_FILES['upfile']['name'] . "<br>";
echo "UPFILE " . $_FILES['upfile'] . "<br>\n";

$upfile_name = $_FILES['upfile']['name'];

// set directory where you will be uploading (Make sure to 
// CHMOD to 777 
$dir = "Files";

// if no file was uploaded
if (($_FILES['upfile']['name'] == "")) {
   echo "No file Uploaded. Please go back and try again";
   exit;
}

// if a file with that name already exists on server
if (file_exists("$dir/$upfile_name")) {
   echo "A file with that name already exists on server. Please go back and try again";
} else {

// upload file
   if (is_uploaded_file($upfile)) {
      copy($_FILES['upfile']['tmp_name'], "$dir/$upfile_name");
      echo "File Uploaded Successfully";
   }

}

?>

What does that print on the page?

Daggeth

Sorry for all the trouble. I tried on another host and it worked. Seems like my host disabbled uploads.. Why in the world would they do that... Idiots. And to think.. I pay them

cgraz

Try replacing the copy function with move_uploaded_file

I think I've had that problem before, where one or the other function didn't upload on a particular host. Just something to try.

No it doesnt work, but it doesnt matter either. Im leaving this host anyways.
