file handling

gthri

hi,
i need to upload and download files(pdf or doc file) in my page using php.
once the user enters the login page it shd display his own company information and he can either upload or download files and shd be able to view the archived ones
can somebody suggest me how to do this?

home_spun

there are 2 files attched
one is for upload and other is for display

home_spun meant actual code you have? At the moment it all sounds theoretical with no practical implementation.

oh sorry the file didnt attach properly.
here is the code

<?php
function display_form($errMsg){
global $dir_path;
?>

<html>
<head><title>File Manager</title></head>
<body bgcolor="#E5E5E5">
<div align="center">
<h4>File Manager</h4>

<?php
if($errMsg){
?>

<?php
}
?>

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" enctype="multipart/form-data" method="POST">
<table border="1">
<tr>
<th>File Location:</th>
<th><input type="file" name="up_file" /></th>
</tr>
<tr>
<th colspan="2"><br><input type="checkbox" name="replace" value="1">
Replace Existing File*</th>
</tr>
<tr>
<th colspan="2"><br><input type="submit" name="upload" value="Upload File !" /></th>
</tr>
</table>

<br><font face="verdana, helvetica" size="1" color="#808080">* - Clicking this option will replace the existing file</font>
<br><font face="verdana, helvetica" size="1" color="#808080"><a href="file_display_manager.php">File Manager</a></font>

<p><br><font face="verdana, helvetica" size="2" color="#808080"><b>Folder Location:</b><? echo $dir_path ?></font>
<br><font face="verdana, helvetica" size="1" color="#808080">You can change this location by editing the file</font>

</form>
</div>
</body>
</html>
<?php
}

?>

for the upload part i have

<?
$dir_path="C:\Program Files\Apache Group\Apache\htdocs\filemanager";
?>
<?php
function Get_New_File_Name($file_name)
{

    $sqlQuery="SELECT  file_image_name 
           FROM file_manager 
           WHERE  file_name LIKE '$file_name%'
         AND  file_parent_id=1";

    $fResult=mysql_query($sqlQuery);
    $Last_Version=0;
    $ver=0;

    if(mysql_num_rows($fResult)){
        while($fRow=mysql_fetch_array($fResult)){
        list($junk,$ver)=explode("_VERSION",$fRow['file_image_name']);
        list($ver,$extn)=explode(".",$ver);
        $Last_Version = $Last_Version > $ver ? $Last_Version : $ver;
    }
}else{
    $new_file_name =$file_name."_VERSION".++$Last_Version;
    return $new_file_name;
    }

if($Last_Version !=0){
    $new_file_name=$file_name."_VERSION".++$Last_Version;
    return $new_file_name;
    }
}

?>
<?php
function File_Size($size)
{
if($size > 104876){
return $return_size=sprintf("%01.2f",$size / 104876)." Mb";
} elseif($size > 1024){
return $return_size=sprintf("%01.2f",$size / 1024)." Kb";
} else {
return $return_size=$size." Bytes";
}

this doesnt seem to work ?where does the problem lie?
