im trying to implement uploading via a meta box without using the media manager, but i want it to add as a post attachment.
im currently doing it just uploading and saving to the server.
<?php
define("THUMB_DIR", WP_CONTENT_DIR . '/plugins/meta-upload/thumbs/');
define("THUMB_URL", WP_CONTENT_URL . '/plugins/meta-upload/thumbs/');
// this needs to be implemented
function fileupload( $label ) { ?>
<tr>
<td class="left_label"> <?php
echo $label; ?>
</td>
<td>
<form name="uploadfile" id="uploadfile_form" method="POST" enctype="multipart/form-data" action="<?php echo $this->filepath.'#uploadfile'; ?>" accept-charset="utf-8" >
<input type="file" name="uploadfiles[]" id="uploadfiles" size="35" class="uploadfiles" />
<input class="button-primary" type="submit" name="uploadfile" id="uploadfile_btn" value="Upload" />
</form>
</td>
</tr>
