[wp-hackers] Uploading image attachments from the front-end

Hello all,
I'm working on a collaborative editing system for WP and I'm trying to
figure out how to access WP's media features from the frontend.
wp_insert_attachment works just fine, but if I try to generate a
thumbnail or the image metadata, WP shuts down and stops loading the
page. I think this is because these functions are only supposed to run
from the admin area but I'm not sure. This is what my code looks like:
function sw_photo_upload() {
if ($_FILES != null) {
$upath = wp_upload_dir();
$target_path = $upath['path'].'/';
$target_path = $target_path . basename( $_FILES['uploadedfile']
['name']);
$target_uri = $upath['url'].'/'.basename( $_FILES['uploadedfile']
['name']);
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'],
$target_path)) {
echo "The file ". basename( $_FILES['uploadedfile']['name'])."
has been uploaded";
echo $target_path;
$attach = array();
$attach['guid'] = $target_uri;
$attach['post_title'] = basename( $_FILES['uploadedfile']['name']);
$attach_id = wp_insert_attachment($attach, $target_uri,
$_POST['parent']);
wp_create_thumbnail($attach_id, '90');
//wp_generate_attachment_metadata( $attach_id, $target_path );
} else {
echo "There was an error uploading ".$_FILES['uploadedfile']
['name']." to ".$target_path.". PHP returned the following error: ".
$_FILES['uploadedfile']['error'];
}
}
}
There's lots of debugging stuff in there and I'm sure it's very
sloppy, but I don't understand why wp_create_thumbnail causes
everything to crash. It executes just fine if I comment that line out,
but I want to use WP's built in thumbnail generation. Is there a good
way to do this?
(And yes, I know this needs security improvements, that's my next step
once it's working).
