Disable external links?

[brettuk]

Hi,

Is there any way I am able to make it so NO-ONE, besides Admins, can post external links?

Even by BBC code and writing the code manually, etc.

I'd only like external links to be shared via PM's, not posts or threads.

Thanks!

[Illori]

not possible by default.

There probably is a way but it may take a lot coding.

The edit is actually fairly simple.

File: ../Sources/Post.php

find (near top of Post2() function):

Code Select Expand


// Previewing? Go back to start.


insert BEFORE the above comment line:

Code Select Expand


$replacement = '';
$search = array('/\[url\](.*?)\[\/url\]/is'  . ($context['utf8'] ? 'u' : ''), '/\[url\=(.*?)\](.*?)\[\/url\]/is'  . ($context['utf8'] ? 'u' : ''), '/\<a(.*)\>(.*)\<\/a\>/iU'  . ($context['utf8'] ? 'u' : ''), "/(?i)\b((?:(http|https)?:\/\/|www\d{0,3}[.]|[a-z0-9.\-]+[.][a-z]{2,4}\/)(?:[^\s()<>]+|\(([^\s()<>]+|(\([^\s()<>]+\)))*\))+(?:\(([^\s()<>]+|(\([^\s()<>]+\)))*\)|[^\s`!()\[\]{};:'\".,<>?]))/"  . ($context['utf8'] ? 'u' : ''));
if (isset($_POST['message']) && empty($user_info['is_admin']))
$_POST['message'] = preg_replace($search, $replacement, $_POST['message']);
elseif (isset($_REQUEST['message']) && empty($user_info['is_admin']))
$_REQUEST['message'] = preg_replace($search, $replacement, $_REQUEST['message']);


.. just change the value of $replacement to what you want links replaced with (within its quotes).

Hey, it was easier than I thought, thanks man.

Actually 2 edits if you want it to also effect previewing.
You can forget about the previous edit (it should be shorter..) & do these 2 instead

file: ../Post.php

for "preview" find:

Code Select Expand


// Previewing, modifying, or posting?


add BEFORE that comment:

Code Select Expand


$replacement = '[LINK OMITTED]';
$search = array('/\[url\](.*?)\[\/url\]/is'  . ($context['utf8'] ? 'u' : ''), '/\[url\=(.*?)\](.*?)\[\/url\]/is'  . ($context['utf8'] ? 'u' : ''), '/\<a(.*)\>(.*)\<\/a\>/iU'  . ($context['utf8'] ? 'u' : ''), "/(?i)\b((?:(http|https)?:\/\/|www\d{0,3}[.]|[a-z0-9.\-]+[.][a-z]{2,4}\/)(?:[^\s()<>]+|\(([^\s()<>]+|(\([^\s()<>]+\)))*\))+(?:\(([^\s()<>]+|(\([^\s()<>]+\)))*\)|[^\s`!()\[\]{};:'\".,<>?]))/"  . ($context['utf8'] ? 'u' : ''));
if (isset($_REQUEST['message'])  && empty($user_info['is_admin']))
$_REQUEST['message'] = preg_replace($search, ($replacement), $_REQUEST['message']);

if (isset($_POST['message']) && empty($user_info['is_admin']))
$_POST['message'] = preg_replace($search, $replacement, $_POST['message']);


Again.. change [LINK OMITTED] in either/both to what you want as replacements.

That will, however, affect ALL links, not just external links

If you haven't yet, think you should consider disabling:
- Automatically link posted URLs
- Url BBC
- Enable basic Html

These are all on the Features and Options | Bulletin Board Code page in the Admin Control Panel.

These are all on the Features and Options | Bulletin Board Code page in the Admin Control Panel.

As a bonus, admins would be able to post working links using the [html] tags.

This will allow $boardurl but I wrote it so you can add allowed site links in the $allowed array.

file: ../Post.php

$length = strlen($allow);
if (substr($m[0], 0, $length) == $allow)
return $m[0];
}

return $replacement;
}, $_REQUEST['message']);

$_REQUEST['message'] = rtrim($new);
