[PHP] file upload

[anders thoresson]

Am I making any obvious mistakes here, in my upload script? I want to 
upload text-files only, they should end up in the directory from which the 
script is executed and be names __traningsmatcher.txt.

HTML-form:

<FORM ENCTYPE="multipart/form-data" METHOD=POST ACTION="store.php">
<TABLE>
<INPUT NAME="max_file_size" TYPE="hidden" VALUE="3000000">
<TR>
        <TD>Fil: </TD>
        <TD><INPUT NAME="userfile" TYPE="file"></TD>
</TR>
<TR>
        <TD></TD>
        <TD><INPUT TYPE=submit VALUE=" skicka "></TD>
</TR>
</TABLE>
</FORM>
And php, on the recieving end:
<?php
	// check and validate uploaded file

        if($_FILES['userfile'] == "none")     {
                die("Problem: Ingen fil uppladdad.");
        }
        
        
        if($_FILES['userfile']['size'] == 0)    {
                die("Problem: Filen är tom.");
        }
        
        if($_FILES['userfile']['type'] != "text/plain")       {
                die("Problem: Filen är inte en textfil.");
        }
        
        if(!is_uploaded_file($_FILES['userfile']['tmp_name']))  {
                die("Problem: Filen är inte uppladdad");
        }
	$upfile = "__traningsmatcher.txt";

        if(!copy($_FILES['userfile']['tmp_name'], $upfile))     {
                die("Kunde inte spara filen");
        }
	echo("Filen är sparad!");

?>
