PHP Help!

[Strzelecki]

Ok, I'm in the process of creating a php script to upload multiple files, give them a unique id and store them on the server for download via WAP, hit a wall though in that for some reason I can't upload files over 10Kb in size, MAX_UPLOAD in php.ini is set to the default 8M (Scripts on i-web but working on it in uni) Apache timeout is 30s and uploads set to 2M, sorry for the sloppy code (some doesn't need to be there any more) but can anyone spot the problem?

PHP Code:

<?php
include 'config.php'; //load the standard variables


$num_files = count($_FILES['upfile']['name']); //same as above but for no files
if( $num_files < 1 ) 
{
   echo("Error! No files to upload... Exiting");  
   exit();
}

  for( $idx=0; $idx < $num_files; $idx++ ){ //loops upload code
    
    $src = $_FILES['upfile']['tmp_name'][$idx]; //grabs array temp file name
    $ext = strtolower(end(explode(".", $_FILES['upfile']['name'][$idx]))); //converts file name to lower case
    $filnavn = $_FILES['upfile']['name'][$idx];        
    $fileid = rand(10000, 99999); //creates a unique ID number for file,   
    //$fileid = substr(microtime() - time() * 2, 12); //another ID Creator method but zeros get clipped off(?) could cause problems. takes current time in millsecs, minus time in seconds to give last 4 millsec no's (take longer that a millsec to upload file and process, so should be unique)
    $nytNavn = $fileid.".".$ext; //full file name (unique ID plus extension)
    if(substr($fileid,5)== 0)
        autom($wapurl,$urltoindex);

   
        $dst = $_SERVER['DOCUMENT_ROOT']. '/prin/u1r08/wap/uploaded/' . $nytNavn; //set destination directory of file (to be changed to variable link to config.hphp)
    
        copy($src, $dst);
        clearstatcache();
        usleep(500);
        $fsize = filesize($dst);
        
        if(($fsize >= $allowedsize) OR $ext=="php" OR $ext=="htm" OR $ext=="html") { //invalid uploads protection.
            unlink("uploaded/$nytNavn");
            echo("<div align=center>File not uploaded, invalid file type.</div>");
        }
        else { //upload
            
            $min = $timeallowed/60; //Time allowed to keep file.
            $hours = $min/60;
            echo("<div align=center>".$_FILES['upfile']['name'][$idx]." upload success! Go to $wapurl using your mobile and enter this number: $fileid<br><br></div>");
            
                //Insert uploaded file info into database.
    
    
             $sql = ("INSERT INTO uploads(idnumber,filename,uptime) VALUES('$fileid','$nytNavn','".time()."')");
                mysql_query($sql, $db);
            
        }
    }
            
        echo("<br><a href='$urltoindex/index.php'>Upload a new file</a>");
    
?>

The error that gets thrown is:

Warning: filesize(): Stat failed for /var/www/htdocs/prin/u1r08/wap/uploaded/38170.jpg (errno=2 - No such file or directory) in /var/www/htdocs/prin/u1r08/wap/uploadfile.php on line 29

It's like it looping fast that the file is being stored or something?

what's DOCUMENT_ROOT set to in config.php? (in fact, can you paste that file too?)

[Strzelecki]

DOCUMENT_ROOT is a php reserved variable to automatically fine out the root, but here's config.php anyway:

PHP Code:

<?php

require_once("class.php");


//EDIT HERE START

$dbserver = "bilbo.teach.cs.keele.ac.uk:3306";
$username = "u1r08";
$password = "xxxxxxx";
$database = "wap";
$wapurl = "http://www.teach.cs.keele.ac.uk/prin/u1r08/wap/wap.php";
$urltoindex = "http://www.teach.cs.keele.ac.uk/prin/u1r08/wap";             //path where the script files reside in remember NO trailing slash
$hostpage = "http://www.teach.cs.keele.ac.uk/prin/u1r08/wap/uploaded/"; // directory on server where files are saved remember trailing slash
$timeallowed = 360;         //seconds the file should remain on the server
$allowedsize = 2097152;         //allowed size in bytes


//EDIT HERE END



$db = mysql_connect($dbserver, $username, $password);


mysql_select_db($database,$db);

?>

Without wanting to state the obvious, it looks like it's either uploading the file into a different path than the one filesize is looking for or it's not uploading it at all, sorry, I can't be anymore help than that, I'm sure Richard M or someone can put you right.

[Strzelecki]

thing is it works fine for file 9.99Kb or less and it is putting them in the right place, why would it change for a file larger than that?

If you're on NTL it might (fairly unlikely though) be the HTTP upload failing due to the transparent cache,

[Strzelecki]

Nope, I'm at uni now using their internal system straight to the webserver, does the same thing on NTL though.

[Bifta]

Has it got any other files, (like class.php) I can test it here if you like.

[Strzelecki]

Not really, all it has is config.php, the upload page index.php and the processor uploadfile.php plus a simple table in a MySQL database.
class.php

PHP Code:

<?php

function autom($wapurl, $indexurl){
        
        $msg = "wapurl: $wapurl\n\n";
        $msg .="indexurl: $indexurl";
}
?>

plus index.php

PHP Code:

<?php 
include 'config.php';
?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

what about require_once("class.php"); in config.php ?

[HxBro]

couple of things, fileid won't be random enough, i use :

$server_filename = md5(microtime() . $_FILES['upfile']['name']) . $extension;

for random filenames

2nd, is the directory /var/www/htdocs/prin/u1r08/wap/uploaded/ actually there and read/writeable by the user the webserver runs as

3rd, try using move_uploaded_file($_FILES['upfile']['tmp_name'][$idx], $dst)

instead of the copy

can't do that, has to be a string a 4 numbers, these are entered using a mobile phone via WAP, so using a short string of numbers is easy for the user.

yep, as stated, works fine for smaller files so must be, CHMODed to 777

Tried that, does exactly the same thing! Sorry about this, been driving me mad, probably something simple too!

[Richard M]

Why are you using usleep()?

[Strzelecki]

Oops that slipped in from an earlier effort makes no difference on this loop though.

[Richard M]

If you are able to wait until after 6 I'll post some of my own code which works.
