[attachment]id[/attachment] BBcode

What it does
This hack is a "clone" of the IPB [attachmentid=xxx] BBcode feature. It allows you to insert anywhere in your posts a link to an attachment, using its ID (therefore making it an inline attachment). It also detects the file type and shows either the thumbnail (with a link to the full image), the full image or a text link.
If the attachment doesn't exist or has been moderated, nothing will be shown.
By the way, maybe this should be a VB feature?


What is required
- 1 PHP file edit ("includes/functions_showthread.php")
- 1 CSS style edit
- 1 image upload ("images/misc/inlineattach.gif")


What can be done
- hide the [attachment] BBcode in the search results page
- handle (hide?) the [attachment] BBcode in the printable version
- handle (hide?) the [attachment] BBcode in the archive


Notes
- This hack will add 1 query per attachment BBcode, and the usual amount of queries for the "attachment.php" file call in case of a thumbnail or an inline image.
- The "howto.txt" is provided because it includes the indented code that VB loses with PHP and CODE tags.
- The PSD of the image is provided for personal editing.
- The french version of the image is provided (don't forget to rename it).
- This is my first released hack, so please be cool


Support
I may not be able to provide support for this hack.


Howto (also provided in "howto.txt")
1. Open "includes/functions_showthread.php".

2. Go to (around line 604):

PHP Code:

    $post['message'] = parse_bbcode($post['pagetext'], $forum['forumid'], $post['allowsmilie']);
} 


Add below:

PHP Code:

 //ATTACHMENT BBCODE HACK BEGIN
$post['message'] = preg_replace_callback('#\[attachment\]\s*(\d+)\s*\[/attachment\]#siU', 'attachment_bbcode_callback', $post['message']);
//ATTACHMENT BBCODE HACK END 


3. Go to (at the end of the file):

PHP Code:

 return "$prepend$text";
} 


Add below:

PHP Code:

//ATTACHMENT BBCODE HACK BEGIN
// ###################### Start attachment_bbcode_callback #######################
function attachment_bbcode_callback($matches)
{
global $DB_site, $vboptions, $bbuserinfo, $session, $stylevar;

4. Save and upload "includes/functions_showthread.php".

5. Upload "inlineattach.gif" in "images/misc/".

6. Edit your style(s) Main CSS, and add this to your additional CSS (bottom of the page):

img.inlineattach {
background-color: #336699;
background-image: url('images/misc/inlineattach.gif');
background-position: bottom right;
background-repeat: no-repeat;
margin: 0px 2px 0px 0px 0px;
padding: 2px 2px 14px 2px;
}

(NB: #336699 is the background color of "inlineattach.gif")


Usage
[attachment]id[/attachment]


Demo
Have a look at the attached screenshots.

The solution is to move line starting with
$post['message'] = preg_replace_callback(...
ABOVE the line starting with
$post['message'] = parse_bbcode($post...
in an original code.

The effect is that attachment bbcode will be parsed before all other bbcodes, and parsed post presentation will be stored correctly afterwards by parse_bbcode() function.

UPDATE: did some testing, the above won't work either. All parsing should be done in parse_bbcode2() from functions_bbcodeparse.php. I was able to fix this, if anyone interested, I can release the necessary updates here.

I would like to give this hack a whirl with your fix.

has anyone made any updates to this?
