file size

[cab]

I am having difficulty checking the file size of a file before it is uploaded to the server.

What I want to do when the user clicks the 'UPLOAD' button is check the file size and then either continue and upload the file or display and error.

I cannot seem to get the file size until the file has been uploaded?

Any help much appreciated.

Code follows ...

print ("$File_size");

if ($File)
{
print ("<font face=\"MS Sans Serif\"><font color=\"#000000\"><b>File name:</b> $File_name</font><P>\n");
print ("<font face=\"MS Sans Serif\"><font color=\"#000000\"><b>File size:</b> $File_size</font><P>\n");

if (filesize($File) >25600)
		{
		print ("<font face=\"MS Sans Serif\"><font color=\"#000000\"><b>File Is Too Large To Be Uploaded.</b><P>\n");
		}
/*else
{

	if (copy ($File, "../images/$File_name")) 
	{
	print ("<font face=\"MS Sans Serif\"><font color=\"#000000\"><b>File Was Successfully Uploaded.</b><P>\n");
	}
	else 
	{
	print ("<font face=\"MS Sans Serif\"><font color=\"#000000\"><b>An Error Occurred - File Could NOT Be Uploaded.</b><P>\n");
	}
}*/
unlink ($File);

}

print ("<FORM ACTION=\"FileUpload.php\" METHOD=POST ENCTYPE=\"multipart/form-data\">");
print ("<font face=\"MS Sans Serif\"><font color=\"#03CD00\"><b>File Name: </b></font>");
//print ("<INPUT TYPE=HIDDEN NAME=\"MAX_FILE_SIZE\" VALUE=\"25600\">");

print ("</font><INPUT TYPE=FILE NAME=\"File\" SIZE=60>\n<p>");
print ("<font face=\"MS Sans Serif\"><input type=\"submit\" value=\"Upload Now\" style=\"color: #03CD00; font-weight: bold\" >");

print ("<INPUT TYPE=\"button\" value=\"CLOSE THIS WINDOW\" onClick=\"window.close();return false\" style=\"color:#FF0000; font-weight: bold\"></font></FORM>\n");
?>😕

First, you should recode that entire thing.

Second, the file has to be uploaded before the file size can be read. PHP cant read the local machine, it stores the file in a temp directory until your done with it.

Here is a little upload script. Just a snippet and not the best, but it works...

if (isset($_POST['submit']))
{
  	if(is_uploaded_file($_FILES['user_file']['tmp_name'])){
		$allowed = array("image/jpeg", "image/pjpeg", "image/jpg");
		$max_size = "50000"; // about 50kb
		if($_FILES['user_file']['size'] > $max_size){ echo "Error: File is too large."; exit; }
		if(in_array($_FILES['user_file']['type'], $allowed)){
			if(move_uploaded_file($_FILES['user_file']['tmp_name'], $site_dir."/images/".$_FILES['user_file']['name'])){
				$message = $la_updated;
			} else {
				$message = "Error: Could not move uploaded file.";
			}
		} else {
			$message = "Error: Wrong file type.";
		}
	} else {
		$message = "Error: File not uploaded to be moved!";
	}
	unset($_POST['submit']);
}// end if ($submit)  

echo "<h2>Logo Changer</h2>";
echo"<div align='center'>$message</div>";
echo"<form method=\"post\" action=\"logo_change.php\" enctype=\"multipart/form-data\">
<table border=\"0\" width=\"95%\"><tr><td><b>$la_curr_logo</b></td></tr><tr><td><img src=\"".$site_url."/images/store_logo.jpg\"></td></tr></table><br>
<table border=\"0\" width=\"95%\"><tr>
<td><b>$la_select_logo</b></td></tr><tr>
<td><input type=\"file\" name=\"user_file\" class=\"submit\"></td></tr><tr>
<td>$la_store_logo_info</td>
</tr>
<tr>
<td><input type=\"submit\" class=\"submit\" name=\"submit\" value=\"$la_go\"></td>
</tr>
</table>
 </form>";

There are some variables in there from includes and such, but you should get the idea.

How would I tell it I only want PDF files to be allowed? The only error catching I have now is if there is no file at all selected.

if (!is_uploaded_file($HTTP_POST_FILES['userfile']['tmp_name'])) {
echo 'You did not upload a file! Click the back button and click "Browse" to select a file.';

Try a bit of client-side programming to check file size and extention before starting the upload. Hint: javascript again.
