Hey all,
i am using move_upload function to upload files to the server, but i
want to add a feature that will allow files to be archived that have
been uploaded already.
so, the problem is:
i upload a file that i want to upgrade and move the old file to an
archive directory but I want to verify the NEW file is upload BEFORE
moving the old file (the file being uploaded might not have the same
filename as the old file currently on the server)..
i want to move the old file only when the new file was successfully
uploaded. something like:
if(move_uploaded_file())
{
rename(...);
}
only one problem.. then if both files have the same name it will be
overwritten before it moves the old one i want to save. if i move the
old one first, there still the possibility of the new upload failing so
i am back to square one..
i guess i can move_upload to a different directory, verify it's been
uploaded, move the old to the archive file, then move the new file back
to where it should be (where the archive file was)..
is that my only option? any suggestions?
I'd suggest you *copy* the old file (if it exists) to archive anyway, and then
*move* it back if the new version doesn't verify. That seems pretty safe to
me...

[PHP] Re: File Upload Question
As far as I know, this is not possible. You can however generate more file-upload boxes dynamicly. In this way, users can click an 'Upload another file'-button to display an extra upload form-element. Check the 'variable variables'-part in the PHP reference (user notes) for an example of this construction. Hope this is good solution for your application. greetz, Arnout Boks Warren Vail [EMAIL PROTECTED] schreef in bericht news:[EMAIL PROTECTED] Perhaps this is more about HTML than PHP, but the PHP $_FILES var seems to be set up to allow a list of files to be uploaded. How does one get the pop-up window to allow a user to select (ctrl-click or whatever) multiple files in the same pop-up window? Everything I have tried has left the user restricted to selecting one file only. thanks in advance.

[PHP] Re: File Upload Question...
Your first question. To see that the file uploaded successfully using the
web browser, one would have to have access to your computer's file system.
In her book, she used this merely as an example to show that the file had,
indeed, been uploaded. This should not be used as something that you allow
your web users to do to confirm the receipt of the file. Instead, send them
an email, show them a directory listing, etc.
Your second question, the name given to the image should be whatever the
*value* of the variable used to copy() it. You should, however, come up
with a naming scheme that allows you to ensure that you do not overwrite any
uploaded files--especially if you expect a lot of traffic and/or users using
this feature.
Your third question, the mime-type pjpg is functionally the same as the
mime-type jpeg. There's nothing you need to worry about there.

Merry Christmas everybody.
I am using MS Windows 98 with Apache and following an example in Julie
Meloni's PHP - Fast and Easy (Chapter 10) in which she describes file
uploading using PHP on page 168-174.
She has two files:
1) an html form to receive the input from the user for the file to be
uploaded
2) a .php script to accept the variable and use the copy() function.
.
The scripts are as follows:
(html form)
HTML
HEAD
TITLEUpload a File/TITLE
/HEAD
BODY
H1Upload a File/H1
FORM METHOD=post ACTION=do_upload.php ENCTYPE=multipart/form-data
pstrongFile to Upload:/strongbr
INPUT TYPE=file NAME=img1 SIZE=30/p
PINPUT TYPE=submit NAME=submit VALUE=Upload File/p
/FORM
/BODY
/HTML
(.php script)
?
if ($img1_name != ) {
@copy($img1, c:/Program Files/Apache Group/Apache/htdocs/$img1_name)
or die(Couldn't copy the file.);
} else {
die(No input file specified);
}
?
HTML
HEAD
TITLESuccessful File Upload/TITLE
/HEAD
BODY
H1Success!/H1
PYou sent: ? echo $img1_name; ?, a ? echo $img1_size; ?
byte file with a mime type of ? echo $img1_type; ?./P
/BODY
/HTML
..
My questions:
I am able to upload a file from My Documents to the Apache server however
in her book, she describes that the user can verify that the file was
uploaded to the server by going to:
File/ Open Page / in ones web browser to navigate through their filesystem
to
find the file that was uploaded. There is a screenshot in the book that
shows the .jpeg file on the screen with the browser at:
file:///C/Apache/htdocs/blahblah.jpg
I can't seem to verify that the file exists using this method.
The only way I can verify that the file was indeed uploaded is to go into
the folder within Apache that was specified in the path and check there.
*How can I check by going through the browser window?*
Next question:
When I check that the file was uploaded, the file is saved in:
C:/Program Files/Apache Group/Apache/htdocs/$img1_name
as the *regular *.jpeg name I originally gave it - not the variable -
$img1.
Is this correct? Or, should the file be saved as:
img1?
And the last question:
This is the line I received upon sending the file:
You sent: KewpieSmall.jpeg, a 3127 byte file with a mime type of
image/pjpeg.
In her book, it says:
image/jpeg.
What is:
image/pjpeg.?
Many thanks and best wishes to all for a happy and healthy new year.

[PHP] Re: File Upload Question...
Hi,
Remember 2nd Q: The file is Upload to a temporaly direcory, later you copy from
temporaly (temporaly name) to a final (rename the file) destination.
Under *NIX, I don't if Windows's PHP when upload tthe file, the file is copied to a
temporaly directory.
Bye,
I've still My Question about PHP_AUTH_USER and Browsers :-)
