Help! Loop doesn't work for uploading big files

[bbeban]

I am trying to do a loop on an upload form that looks to see if the file has landed in the destination directory yet and sleeps for 5 seconds each time the file is not found, until after 10 times it forwards to a timeout page. The part of this code intended to loop and go to a timeout page is not working, though it uploads fine and goes to the thanks page if the file is a reasonable size:

if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "form1") &&
    (isset($_POST['submitted']) && $_POST['submitted'] == "yes" )) {
  $filecheck = 1;
  while(!file_exists($loaddir."/".$newName) && $filecheck < 10) {
    sleep(5);
    $filecheck = $filecheck + 1;
    clearstatcache();
	}
  clearstatcache();
  if (file_exists($loaddir."/".$newName)) {
    $insertSQL = sprintf("INSERT INTO $tablename (name, filename, link, location_d, location_p) VALUES '$username', '$newName', '$loaddir/', '$origin_link', '$location_p')"); 


$Result1 = mysql_query($insertSQL, $dbset) or die(mysql_error());

if ($_POST['research'] == 'Y' OR $_POST['proj_on'] == 'Y' OR $_POST['dept_on'] == 'Y' OR 
    $_POST['notification'] == 'Y') {
  $insertSQL = sprintf("INSERT INTO table (logon, name, research, proj_on, project, dept_on, department, 
text, notification, emails, dirpath, filename) 
VALUES ('$logon', '$username', %s, %s, %s, %s, %s, %s, %s, %s, '$loaddir/', '$newName')",
		       GetSQLValueString($_POST['research'], "text"),
		       GetSQLValueString($_POST['proj_on'], "text"),
		       GetSQLValueString($_POST['project'], "text"),
		       GetSQLValueString($_POST['dept_on'], "text"),
		       GetSQLValueString($_POST['dept'], "text"),
		       GetSQLValueString($_POST['text'], "text"),
		       GetSQLValueString($_POST['notification'], "text"),
               GetSQLValueString(implode("<\/option><option>",$_POST['emails']), "text"));
      $Result1 = mysql_query($insertSQL, $dbset) or die(mysql_error()); }

$insertGoTo = "thx_page.php";
if (isset($_SERVER['QUERY_STRING'])) {
  $insertGoTo = $insertGoTo."?origin_link=".$origin_link."?".$newName;
  }
header(sprintf("Location: %s", $insertGoTo));
die();
} /* end if file exists */
  else {
    $insertGoTo = "timeout.php?origin_link=$origin_link&location_p=$location_p&filename=$newName
&loaddir=$loaddir&pathdir=$pathdir&research=$research
&proj_on=$proj_on&project=$project&dept_on=$dept_on&dept=$dept
&textsent=$textsent&notification=$notification&emails=$emails";
    if (isset($_SERVER['QUERY_STRING'])) {
      $insertGoTo .= (strpos($insertGoTo, '?')) ? "&" : "?";
      $insertGoTo .= $_SERVER['QUERY_STRING'];
      }
    header(sprintf("Location: %s", $insertGoTo));
    die();
    } /* end else */
  } /* end if posted */

Can anyone out there help me get this loop to a working state? Thanks many times over --

P.S. I inserted line breaks in the fields list and broke up the long list of URL args to make this post more readable, so that's not the problem.

well, without looking at your code, is it just timing out before the 50 seconds is up?

By the way, what is the error message? Does anything come up?

It's also possible your file is so large that the upload portion of your code takes so long it's not getting to your while loop.

P.S. If your goal is to avoid uploading file sizes that are too large, there are ways to reject it before your browser will upload it.

information is here

No, it's not timing out before then, nor via the code in the page -- I have adjusted the settings in php.ini to accommodate large files (our max size is 10M😎 so the server is timing out after, like, 2-3 minutes or something as far as I can tell.

No error message is coming up.

I will have another look at php.ini and see what effect I can have there.

In the meantime, can you or anyone else look at the code I posted and tell me if there's any way to improve it?

Thanks --
