[mgn]

My code, is to get data from a CSV file and place it in MYSQL DB.
This works perfectly in local server.

When iam  trying  to setup my webpage, which  i tried to perform same task is to load
that csv file's data into mysql table,but it won't work!! don't know why!!

The error  says "No such file or directory"
[code]
if ( $_REQUEST['readhid'] != "")
{

$path = htmlentities($_POST['file']);
$date = htmlentities($_POST['date']);
   
  $filename = basename($path);     
  $fd = fopen ($filename, "r");
$contents = fread ($fd,filesize ($filename));
fclose ($fd);

..........................
...............
...........//and code is going on
                  //Error "No such file  or directory".
                //But it perfectly works when tested with localserver.
}

<form  name = "frm" action = "readchk01.php" method ="post">
<table border="0" width="100%" id="table1">
<tr><td>
Enter filename:  <input type = "file" name = "file" /> </td></tr>
