PHP-Fusion Upload Script

[MTGap]

I'm attempting to get a file upload script to work within PHP-Fusion. Unfortunately I can't actually get the file uploaded:

 

} elseif ($_GET['stype'] == "d") {
if (isset($_POST['submit_download'])) {
	if ($_POST['download_name'] != "" && $_POST['imagefile'] != "") {
		copy ($_FILES['imagefile']['tmp_name'], "/downloads/".$_FILES['imagefile']['download_name']); 
		$download_cat = stripinput($_POST['download_category']);
		$download_title = stripinput($_POST['download_name']);
		$download_url = "/downloads/".$_FILES['imagefile']['download_name']."";
		$result = dbquery("INSERT INTO ".DB_DOWNLOADS." (download_title, download_url, download_cat, download_datestamp, download_count) VALUES ('$download_title', '$download_url', '$download_cat', '".time()."', '0')");
		add_to_title($locale['global_200'].$locale['700']);
		opentable($locale['700']);
		echo "<div style='text-align:center'><br />\n".$locale['705']."<br /><br />\n";
		echo "<a href='submit.php?stype=d'>".$locale['706']."</a><br /><br />\n";
		echo "<a href='index.php'>".$locale['412']."</a><br /><br />\n</div>\n";
		closetable();
	}
} else {
	$opts = "";
	add_to_title($locale['global_200'].$locale['700']);
	opentable($locale['700']);
	$result = dbquery("SELECT * FROM ".DB_DOWNLOAD_CATS." WHERE ".groupaccess("download_cat_access")." ORDER BY download_cat_name");
	if (dbrows($result)) {
		while ($data = dbarray($result)) {
			$opts .= "<option value='".$data['download_cat_id']."'>".$data['download_cat_name']."</option>\n";
		}
		echo $locale['420']."<br /><br />\n";
		echo "<form name='submit_form' method='post' action='".FUSION_SELF."?stype=d' onsubmit='return validateLink(this);'>\n";
		echo "<table cellpadding='0' cellspacing='0' class='center'>\n";
		echo "<tr>\n<td class='tbl'>".$locale['701']."</td>\n";
		echo "<td class='tbl'><select name='download_category' class='textbox'>\n$opts</select></td>\n";
		echo "</tr>\n<tr>\n";
		echo "<td class='tbl'>".$locale['702']."</td>\n";
		echo "<td class='tbl'><input type='text' name='download_name' maxlength='100' class='textbox' style='width:300px;' /></td>\n";
		echo "</tr>\n<tr>\n";
		echo "<td class='tbl'>".$locale['704']."</td>\n";
		echo "<td class='tbl'><input type='text' name='download_version' maxlength='100' class='textbox' style='width:300px;' /></td>\n";
		echo "</tr>\n<tr>\n";
		echo "<td class='tbl'>".$locale['703']."</td>\n";
		echo "<td class='tbl'><input type='file' name='imagefile' class='textbox' style='width:300px;'></td>\n";
		echo "</tr>\n<tr>\n";
		echo "<td align='center' colspan='2' class='tbl'><br />\n";
		echo "<input type='submit' name='submit_download' value='".$locale['700']."' class='button' />\n</td>\n";
		echo "</tr>\n</table>\n</form>\n";
	} else {
		echo "<div style='text-align:center'><br />\n".$locale['551']."<br /><br />\n</div>\n";
	}
	closetable();
}
}

 

I get the following error after I submit the form:

 

Notice: Undefined index: imagefile in /home/troop1/public_html/submit.php on line 139

 

Notice: Undefined index: imagefile in /home/troop1/public_html/submit.php on line 139

 

Warning: copy() [function.copy]: Filename cannot be empty in /home/troop1/public_html/submit.php on line 139

 

Notice: Undefined index: imagefile in /home/troop1/public_html/submit.php on line 142

 

Can anyone help me out with this?
