Help restructure code run when set with cronjob

[popuskin2]

The file I wish to run resides on the server xxx.com/test.cvs

 

I want to set a cron job to run the script below every day.

 

<?php

 

 

 

 

include "connect.php";

if(isset($_POST['submit']))

  {

    $filename=$_POST['filename'];

    $handle = fopen("$filename", "r");

    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE)

    {

   

      $import="INSERT into prices values('$data[0]','$data[1]','$data[2]','$data[3]','$data[4]','$data[5]','$data[6]','$data[7]','$data[8]','$data[9]','$data[10]')";

      mysql_query($import) or die(mysql_error());

    }

    fclose($handle);

    print "Import done";

 

  }

  else

  {

 

      print "<form action='csv.php' method='post'>";

      print "Type file name to import:<br>";

      print "<input type='text' name='filename' size='20'><br>";

      print "<input type='submit' name='submit' value='submit'></form>";

  }

 

?>

 

 

Please someone help me restructure it cos cron job can not press the submit button.

 

Thx all
