[RFC] attached_file hook

[AgustinL]

Name: hook_attached_file
Rationale: If we need to parse some extra-information of a file uploaded using the attachment system, for example: count of files included in a .zip file, author information of a .docx file, ID3 tags of and mp3 file, we need to do a parse of the file.
Placement:

includes/message_parser.php

Before:

Code: Select all

$this->attachment_data = array_merge(array(0 => $new_entry), $this->attachment_data);

(around line 1414)

and again before the same code around line 1523
-------------------------------

includes/functions_content.php (for display parsed information in post body)

Code: Select all

$block_array += array(
						'S_FILE'		=> true,
					);
					break;

Input arguments: $filedata array
Output format: An array[key,value] of the parsed information

I second the need for this hook.

[AgustinL]

I wish to add another placement for this hook.

When performing the removal of an attachment, we need to remove (if exist) the stored parsed data of the file.

The hook point should be in the file includes/functions_admin.php, at function delete_attachments(). And will need the attach_id as input.
