Please help: Cannot view uploaded file

sjagan · #1 Jun 25th, 2006, 03:10

I really appreciate & thank you very much for reading my question,here it comes.

Iam new to php & working with xampp on windows since i don have a linux system at the moment & have to get this assignment done asap.I have a problem viewing

the uploaded files in (html/htm & ppt ) format

Iam trying to upload files to a folder i created in Document root.Iam able to upload all the files into the folder,but cannot view them all.

Note: I used a software convertor to convert the excel file to htm format & then uploaded it.

#for the htm file i uploaded its stored as a firefox file into the uploaded folder. When i open the this file from the uploads folder i get a error "This

page uses

frames, but your browser doesn't support them"

I also tried to open the file with IE ,same result.

Is there a way to preserve the format as it was originally.

Now for the PPt File
=========================
# When i open the ppt file i uploaded it says "Powerpoint cannot open the type of file represented by c:\xampp\htdocs\uploads\test.ppt"

# After i upload an image i get " no preview available" when i try to open the image i uploaded.

*****but , i was able to upload & view a text file successfully from the uploads

folder **********

================================================== =

HTML CODE I USED TO BROWSE FILES & send it to storefile.php

html>

<body>
<h1>Upload filest</h1>
<form enctype="multipart/form-data" action="storefile.php" method="post">
<input type="hidden" name="MAX_FILE_SIZE" value="1000000">
Upload this file: <input name="userfile" type="file">
<input type="submit" value="Send File">

</form>
</body>
</html>

================================================== =====

Here is the action code "storefile.php' i use to store the file in uploads folder

in document root

<html>
<head>
<title>Uploading File</title>
</head>

<body>

<?php

// $userfile is where file went on webserver
$userfile = $HTTP_POST_FILES['userfile']['tmp_name'];

// $userfile_name is original file names
$userfile_name = $HTTP_POST_FILES['userfile']['name'];

// $userfile_size is size in bytes
$userfile_size = $HTTP_POST_FILES['userfile']['size'];

// $userfile_type is mime type e.g. image/gif
$userfile_type = $HTTP_POST_FILES['userfile']['type'];

// $userfile_error is any error encountered
$userfile_error = $HTTP_POST_FILES['userfile']['error'];

// one more check: does the file have the right MIME type?

$userfile_type = 'ppt/html';

// put the file where we'd like it
$upfile = 'c:/xampp/htdocs/uploads/'.$userfile_name;

// is_uploaded_file and move_uploaded_file added at version 4.0.3
if (is_uploaded_file($userfile))
{
if (!move_uploaded_file($userfile, $upfile))
{
echo 'Problem: Could not move file to destination directory';
exit;
}
}
else
{
echo 'Problem: Possible file upload attack. Filename: '.$userfile_name;
exit;
}

echo 'File uploaded successfully!!<br /><br />';

// reformat the file contents
$fp = fopen($upfile, 'r');
$contents = fread ($fp, filesize ($upfile));
fclose ($fp);

$contents = strip_tags($contents);
$fp = fopen($upfile, 'w');
fwrite($fp, $contents);
fclose($fp);

?>
</body>

</html>

This may be just a shot in the dark...

Code: Select all

  $upfile = 'c:/xampp/htdocs/uploads/'.$userfile_name;

Are you doing this on your local comp or a server?

Thanks for the reply craig,

Iam testing the upload on my local computer.

so hence i made a folder in document root called uploads & uploaded the files.

The problem is iam able to upload the files to the local folder ,but cannot open the files from that folder.

***Text file can be uploaded& retrieved without any problems ***

I do not know what is the problem .I have also specified mime type of html/plain in the code

Any thoughts what can be wrong ????

Appreciate ur help

PHP: Select all


 // reformat the file contents
   $fp = fopen($upfile, 'r');
   $contents = fread ($fp, filesize ($upfile));
   fclose ($fp);
 
   $contents = strip_tags($contents);
   $fp = fopen($upfile, 'w');
   fwrite($fp, $contents);
   fclose($fp);

I think the reason you can't view your uploaded files is because they are getting corrupted by the above section of code.

Try placing a die(); after your successfull echo message, then upload a file you know you can currently open, make sure you have cleared out any previous uploads first just in case. Once the file has been uploaded test that you can open, I'm sure its the above block that is messing it up for you. Have you checked the permissions on the folder and the uploaded files?
