Attachments in extensions

[Kailey]

Was wondering if someone could post a guide on how to add the attachments feature to an extension. So far all I've done is make an attachment table in a migration.

Code: Select all

$this->table_prefix . 'trackers_attachments'		=> [
	'COLUMNS'		=> [
		'attach_id'				=> ['UINT', null, 'auto_increment'],
		'post_msg_id'			=> ['UINT', 0],
		'ticket_id'				=> ['UINT', 0],
		'in_message'			=> ['BOOL', 0],
		'poster_id'				=> ['UINT', 0],
		'is_orphan'				=> ['BOOL', 1],
		'physical_filename'		=> ['VCHAR:255', ''],
		'real_filename'			=> ['VCHAR:255', ''],
		'download_count'		=> ['UINT', 0],
		'attach_comment'		=> ['TEXT_UNI', ''],
		'extension'				=> ['VCHAR:100', ''],
		'mimetype'				=> ['VCHAR:100', ''],
		'filesize'				=> ['UINT', 0],
		'filetime'				=> ['TIMESTAMP', 0],
		'thumbnail'				=> ['BOOL', 0],
	],
	'PRIMARY_KEY'	=> 'attach_id',
	'KEYS'			=> [
		'filetime'				=> ['INDEX', 'filetime'],
		'post_msg_id'			=> ['INDEX', 'post_msg_id'],
		'ticket_id'				=> ['INDEX', 'ticket_id'],
		'poster_id'				=> ['INDEX', 'poster_id'],
		'is_orphan'				=> ['INDEX', 'is_orphan'],
	],
],

After this, I'm lost as to what service(s) to include and how the code for the form should look so that the file gets added to the DB and to the /files/ directory in my extension.

Looks like that's done around here in the parse_attachments function of the message parser using attachment manager:
https://github.com/phpbb/phpbb/blob/2af ... .php#L1514
https://github.com/phpbb/phpbb/blob/2af ... .php#L1659

Which is used around here in posting.php:
https://github.com/phpbb/phpbb/blob/2af ... .php#L1716

But according to how attachments are dealt with in posting.php there is probably a lot more to it, but maybe this will give you a start (or someone who knows more will come along with a better answer )

Its marked as abandoned, but Image Upload by DMZX might be useful reading. Also available on DMZX's own website

Thanks for the responses all!

There's a lot more, but it's above my head.

Image Upload

That helps for images, but doesn't handle all attachments. I was hoping for a more comprehensive guide using phpBB's own functions as opposed to re-writing the classes.

but doesn't handle all attachments.

*slaps forehead* of course it doesn't. Just ignore me
