[phpBB2] help with code tag modifications

hi guys,

Can someone help me?
I like to make a url clickable inside of a

Code:

 tags. 

I am using a database from an old forum and would like to disable all [code] tags that appears in all posts. I only need this to make urls into links. So, If exists a easy way to make this, please let me know :)
 
Thank you

This is my includes/bbcode.php file:

Have you tried running it in SQL query?

Maybe something like this perhaps?

PHP:

update phpbb_posts set post_text = replace (post_text, '[CODE]', '[URL]')

Maybe there's an easier way. Wait for someone else to give their suggestions.

Divvy · Oct 28, 2009

Hi Danny,

Thank you for your reply and suggestion.
But I dont want to make that, because If someone create a new post with the code tags I will have the same problem.

Really need some modification in my bbcode.php file.

Divvy · Oct 28, 2009

Please, someone?
Need to make urls clickable inside the code tag...

Anyone please?

Divvy · Oct 28, 2009

I tried this:

Find:

PHP:

// [code] and [/code] for posting code (HTML, PHP, C etc etc) in your posts.
$text = bbencode_first_pass_pda($text, $uid, '[code]', '[/code]', '', true, '');

Replace:

PHP:

// [code] and [/code] for posting code (HTML, PHP, C etc etc) in your posts.
//$text = bbencode_first_pass_pda($text, $uid, '[code]', '[/code]', '', true, '');

But appears like that:
http://i38.tinypic.com/v33io8.jpg

Now only need to make the url clickable... If I put the url without the tags appears fine, but with tags and with the modification above, appears like I show in the link above.
Can you make only the url clickable inside the code tag? Please?

litewarez · Oct 28, 2009

Hmmmm try this...

FIND:

Code:

bbencode_second_pass_code

Then look about 20 lines down for:

Code:

$replacement .= $after_replace;

AND REPLACE WITH:

Code:

$replacement .= make_clickable($after_replace);

Shot in the dark tho

Divvy · Oct 29, 2009

hmmmm didn't work! but thanks for trying mate

SplitIce · Oct 29, 2009

If that doesnt work I have a method, use perl regular expressions

Something like this maybe

Code:

$replacement = preg_replace('@(https?://([-\w\.]+)+(:\d+)?(/([\w/_\.]*(\?\S+)?)?)?)@', '<a href="$1">$1</a>', $replacement);

Divvy · Oct 29, 2009

hi SplitIce,

Thank you for your reply.
That didnt work also... but thanks for trying mate

After I made that modification, the post appears like that:
http://i37.tinypic.com/334olfk.jpg

Anymore suggestions?

SplitIce · Oct 29, 2009

Try:

$replacement .= preg_replace('@(https?://([-\w\.]+)+(:\d+)?(/([\w/_\.]*(\?\S+)?)?)?)@', '<a href="$1">$1</a>', $after_replace);

Divvy · Oct 29, 2009

nop, nothing yet... appears like that:
http://i33.tinypic.com/oifwao.jpg

SplitIce · Oct 29, 2009

Try

FIND

Code:
$text = bbencode_first_pass_pda($text, $uid, '

Code:

'

Code:

[COLOR=#007700], [/COLOR][COLOR=#dd0000]'[/COLOR]

', '', true, '');

REPLACE

Code:
$text = bbencode_first_pass_pda($text, $uid, '

Code:

'

Code:

[COLOR=#007700], [/COLOR][COLOR=#dd0000]'[/COLOR]

', '', true, '');
$text.= preg_replace('@(https?://([-\w\.]+)+(:\d+)?(/([\w/_\.]*(\?\S+)?)?)?)@', '<a href="$1">$1</a>', $text);

Divvy · Oct 29, 2009

hmm post is mess... can you fix?

SplitIce · Oct 29, 2009

NO I cant its vb's stupid bbcode parserer lol

http://pastebin.ca/1647256

Divvy · Oct 29, 2009

Try the php tag next time hehe

You said:

FIND

PHP:

$text = bbencode_first_pass_pda($text, $uid, '[code]'[/code][code], '[/code]', '', true, '');

REPLACE

PHP:

$text = bbencode_first_pass_pda($text, $uid, '[code]'[/code][code], '[/code]', '', true, '');
$text.= preg_replace('@(https?://([-\w\.]+)+(:\d+)?(/([\w/_\.]*(\?\S+)?)?)?)@', '<a href="$1">$1</a>', $text);

But I cant find that line... is that correct?

SplitIce · Oct 29, 2009

surely you could figure out that the line was:

PHP:

$text = bbencode_first_pass_pda($text, $uid, '[code]', '[/code]', '', true, '');

Divvy · Oct 29, 2009

And the replace is right?

PHP:

$text = bbencode_first_pass_pda($text, $uid, '[code]'[/code][code], '[/code]', '', true, '');
