ftp upload

[Jocke]

I´m trying to create a way for a user to upload a file (remote) to my server. This should be a case for the ftp functions included in php, or so I thought anyway.
The user will be prompted with a form where he/she may browse their local system for a file, select it, hit the upload button and the script will take care of the rest. However, my script only works when I try it out locally. If anyone atempts the same thing remote, it produces an error. I think it has something to do with file access permissions or something. The script assumes that the file, that is to be uploaded, is on the servers harddrive, not the clients. Naturally, the server therefore can´t find the file!
Is there a way around this problem?

I´m using Apache 1.3.26, PHP 4.2.3 and WinXP.

if(!empty($_GET['upload']))
{
$ftp_server = "xxx.xxx.xxx.xxx";
$name = "aaaaa";
$pass = "bbbb";
$ftp_port = 21;

$src_file = $_GET['file'];
$dest_file = end(Explode("\",$src_file));
$conn_id =& connect($ftp_server,$ftp_port,$name,$pass);

$upload = ftp_put($conn_id, $dest_file, $src_file, FTP_BINARY);

}else{
file_form();
}

function file_form()
{
echo "
<form action='test_ftp.php' method='GET'>
<center>
<table width=400 border=1><tr><td align=center>
<h3>File:

	<input type='file' name='file'>
</td></tr>
<tr><td>
<center><br><input class='button' type='submit' name='upload' value='Upload' style='width=75px' width='75px'>
</td></tr></table>
</form>
</center>";

}

Havnt tried to use the ftp fucntions to accomplish this before,
however you might try changing your form into the right mime type for a file.

enctype=mutlipart/form-data
<input type=file name=userfile value="Browse">

Simply giving the user an option to place the name of the file thye wish to transfer is not good enough. All you are passing is the value of the variable. (ie. the name of the file not the file itself.)

Good Luck,

John

I see your point. I changed the code to the following, but the changes had no effect.

<form action='test_ftp.php' method='GET' enctype='multipart/form-data'>
<input class='text' type='file' allow='text/*' name='file'>

Just like you said, I´m just passing on the filename and not the actual file. The script is still trying to upload a file on the server, not the client. Is there another approach that doesnt include ftp?

We do this with our clients. We let them upload their own products complete with images so that they can add new products to their web sites without our involvement. The two main commands to do this are listed below. In our script, we force the image name to change to another name. Otherwise, you just use the name from the form field (in this case, $imagefile) in the script before. You have to use the complete pathway on their computer though like C:\MyImages\computers\myfavoritecomputer.jpg. Make sure your browse button is returning the whole pathway into your text box.

$dirlocation= "/home/techthreat/www/computer/images/".$image_name;

copy($imagefile, $dirlocation)

No passwords, names, ip addresses, or ftp commands should be needed if the client is running the php script from his www folder. At least we do not need any one ours.

I tried the copy approach and I get the same result as before. Instead of uploading/copying a file from the local computer, the script tries to copy a file from the server (where the script is installed) wich result in an error, since the script is searching on the servers HD for the file.

I guess I could just leave a few files on the server for the users to use on the site. But this is of little help since I want to allow the users to upload/copy their own files (wich is on their computer) to the server.

I have checked, and yes, I do get the full path from the form. I´m beginning to believe it´s a php (or perhaps apache) configuration problem.

Seems rather strange that I can´t get this to work since I know there are a few ftp-scripts written in php. I have tried som of them and I can´t get them to work either! I've also read an article (here at phpbuilder) about the copy function, so this should work. Or is it just a major misunderstanding on my part?

Any configuration ideas, or ideas at all? I´m kinda puzzled over here =)

Each time I tried to upload a file, php created a temporary file and stored it in c:\php\temp. All I had to do was to copy that temporary file to my desired location. It took quite some time before I understood that 🙂

To get the filename of the temporary file, I used
$_FILES['file']['tmp_name']
