Prevent Users With Low Post Counts Posting/PM'ing URLS

Title: Prevent members with low post count posting/pm'ing urls.
Author: NTLDR
Version: 1.0.1
vB Compatibility: vB3 Gamma, RC1, RC2

Description: I created this hack a while ago for use on my board to prevent people signing up and just posting a URL. This hack will prevent users with less than X posts from PM'ing or posting URLs.

File edits:

In includes/functions_newpost.php find:

PHP Code:

        eval('$errors[] = "' . fetch_phrase('toomanyimages', PHRASETYPEID_ERROR) . '";');
    } 

Add after:

PHP Code:

$errors = array_merge($errors, verify_message_urls($post['message'])); 

Find:

PHP Code:

    return sizeof($errors);
} 

Add after (making sure you change REPLACE_NUMBER_OF_POSTS_HERE to the number of posts a user must have before being able to post/pm URLS):

PHP Code:

function verify_message_urls($pagetext) {

    global $vboptions, $vbphrase, $bbuserinfo;

    $errors = array();

    if ($bbuserinfo['posts'] < REPLACE_NUMBER_OF_POSTS_HERE) {
        if (THIS_SCRIPT == 'newthread' || THIS_SCRIPT == 'newreply' || THIS_SCRIPT == 'editpost') {
            $typephrase = $vbphrase['post'];
        } elseif (THIS_SCRIPT == 'private') {
            $typephrase = $vbphrase['private_message'];
        } else {
            $typephrase = $vbphrase['message'];
        }

        if (preg_match('/\[url/i', $pagetext)) {
            eval('$errors[] = "' . fetch_phrase('x_contains_urls', PHRASETYPEID_ERROR) . '";');
            $errored = true;
        }

        $pagetext = strip_bbcode($pagetext);

        if (!$errored && preg_match('/h(\s*)t(\s*)t(\s*)p/i', $pagetext)) {
            eval('$errors[] = "' . fetch_phrase('x_contains_urls', PHRASETYPEID_ERROR) . '";');
            $errored = true;
        }

        if (!$errored && preg_match('/w(\s*)w(\s*)w/i', $pagetext)) {
            eval('$errors[] = "' . fetch_phrase('x_contains_urls', PHRASETYPEID_ERROR) . '";');
            $errored = true;
        }

        if (!$errored && preg_match('/(\w*)(\s*)(\.|dot)(\s*)(c(\s*)o(\s*)m|c(\s*)o(\s*)(\.|dot)(\s*)u(\s*)k|n(\s*)e(\s*)t|o(\s*)r(\s*)g)/i', $pagetext)) {
            eval('$errors[] = "' . fetch_phrase('x_contains_urls', PHRASETYPEID_ERROR) . '";');
            $errored = true;
        }
    }

    return $errors;
} 

If you want this to apply to posts only you don't need to do the following edit which is for PM's:

In private.php find:

PHP Code:

        // process errors if there are any
        if (!empty($errors)) 

Add BEFORE:

PHP Code:

$errors = array_merge($errors, verify_message_urls($pm['message'])); 

Phrases to add:

In Front-End Error Messages add:
Varname: x_contains_urls
Text:

Your $typephrase contains one or more URLs, please remove them before submitting your message again.

Can we get a text install file for this? And, good work there.

[FleaBag]

Another one let out of the bag. Good work. This will hopefully stop my rivals advertising their sites to my members lol.

[Koutaru]

Nice hack this one will really help prevent spamming no?

[Xenon]

instead of

PHP Code:

$url_errors = verify_message_urls($post['message']); 
    foreach($url_errors AS $url_error) { 
        $errors[] = $url_error; 
    } 

i'd use

PHP Code:

$errors = array_merge($errors, verify_message_urls($post['message'])); 

but rather than that, nice one Lee

I had that origionally but it didn't seem to work, although I think that was due to me using $post['pagetext'] which doesn't exisit :P

Thanks for the comments Stefan I've updated the first post with this change.

[Boofo]

What is a good recommended setting for this?

[Erwin]

I've had this running on my site for 2 years now. But I use a much shorter piece of code to achieve a similar result.

[bigdaddy04]

Great hack!
Is there a similar one to 2.3.x versions?

Erwin, wanna share with us?

[NTLDR]

Erwin released and alternative version for vB2.
