uploading images in a plugin.

[wpeloquin]

I am trying to put in an upload picture function on a plugin i am working on, but i cannot get the plugin to work properly. I am obviously doing something wrong, and I am sure it is probably something simple that i am overlooking. The goal is to store the picture name (default.jpg, name.gif, etc) in the database field, and upload the file to $imagedir. The image could then be shown using something like <img src="{vb:raw imagedir}{vb:raw picture variable}" />

This is what i currently have:

<input type="hidden" name="set_user" value="{vb:raw bbuserinfo.userid}" />
<input type="text" name="set_name" id="set_name" class="primary textbox" />
<input type="file" name="set_pic" id="set_pic" class="primary textbox" />

$vbulletin->input->clean_array_gpc('p', array(
	'set_user' => TYPE_UINT,
	'set_id' => TYPE_UINT,
	'set_name' => TYPE_STR,
	'set_pic' => TYPE_FILE,
);

$imagedir = $vbulletin->options['pic_defaultlocation'];
$charpic_name = basename($_FILES['set_pic']['name']);

$path = $wp_imagedir . $charpic_name;

move_uploaded_file($_FILES['set_pic']['tmp_name'], $path);

$vbulletin->db->query_write("
	INSERT INTO `". TABLE_PREFIX ."table`
	(user_id, object_uniqueid, name, pic)
	VALUES (
	'" . $vbulletin->db->escape_string($vbulletin->GPC['set_user']) . "', 
	'" . $vbulletin->db->escape_string($vbulletin->GPC['set_id']) . "', 
	'" . $vbulletin->db->escape_string($vbulletin->GPC['set_name']) . "', 
	'" . $vbulletin->db->escape_string($vbulletin->GPC['set_pic']) . "'
	)
");
