[RESOLVED] Check the filesize using php?

[7724]

Hello,

Wondering if anyone can help.

I have a browse facility on a form.

<input name="ufile[]" type="file" id="ufile[]"  />

And when I hit submit, I save the file to a folder on the server and the path in the database which works great, but I also want to check the image uploaded is less than 2mb? Can anyone see where i'm going wrong as it just uploads the file nomatter the size:

<?
if (isset($_POST['Submit'])) {

  $picunique = md5(uniqid()); // Unique filename for picture
  $picture = "/home/**************/httpdocs/$picunique".$_FILES['ufile']['name'][0];  


// Copy file to where I want to store file
move_uploaded_file ($_FILES['ufile']['tmp_name'][0], $picture);

//Set themax file size as 2mb
$byte="2097152";

// Check for Required Fields with IF statements
       if($_FILES> $byte){
        echo 'Your file is too big';
    }
?>

Thanks

if($_FILES['ufile']['size'][0] > $byte) {

Thanks, but it's still not working. Here's my whole code rather than a snippett:

<?php

if (isset($_POST['Submit'])) {

  $your_name = $_POST['your_name'];
  $picunique = md5(uniqid()); // Unique filename for picture
  $picture = "/home/******************/httpdocs/files/$picunique".$_FILES['ufile']['name'][0];

//Copy file to where I want to store file
move_uploaded_file ($_FILES['ufile']['tmp_name'][0], $picture);

//Set the size of the maximum file
$byte="2097152";

//define a flag variable initially set to 0 for error checking
$flag="0";

// ** Check for Required Fields with IF statements **
    if($_FILES['ufile']['size'][0] > $byte) {
        $error = "<span style='color: #CC0000;'>** Your file is too big **</span>";
        $flag=1; 
    }
       if (empty($your_name)){
        $error = "<span style='color: #CC0000;'>** You forgot to specify your name **</span>";
	$flag=1; 
	}

if($flag != 1)
{  

  $result = mysql_query("Insert into tbl (your_name,picture) values('$your_name','". basename($picture) ."')"); 
  $error = "Thanks the file is uploaded";
}

} //End of POST submit

?>

Now what it's doing is if the picture is less than 2mb everything works fine, but if it's OVER 2mb the picture is NOT uploaded to the folder, but the system still inserts the data in the database and shows the message 'The File has been uploaded'?

Thanks

On reading the code I would have expected the opposite; but I'd suggest doing all error-checking first before doing anything with the file or DB, such as:

<?php
if (isset($_POST['Submit']))
{
   $errors = array();
   $byte = "2097152";
   $your_name = trim($_POST['your_name']);
   if ($your_name === '')
   {
      $errors[] = "You forgot to enter your name.";
   }
   if(empty($_FILES['ufile']))
   {
      $errors[] = "No file was uploaded.";
   }
   elseif($_FILES['ufile']['size'][0] > $byte)
   {
      $errors[] = "Your file is too big.";
   }
   if(count($errors) == 0)
   {
      // do your move file and database insert stuff here
   }
   else
   {
      $error = "<span style='color:#c00'>" . implode(' ', $errors) . "</span>";
   }
}
?>

Thanks, that's magic!
