I noticed that someone asked for a mod that allows specific group IDs to be excluded from post captcha

This is something I implemented on one of my forums a few years ago because some members take out a Paid Subscription as soon as they join and I figured these members shouldn't have to complete captcha for posts (or PMs).  Also, and because I'd actually migrated this particular forum from a vBulletin forum that had been in existence for a few years, I added an option to exclude members who had joined more than a specific time ago from having to complete captcha (some long term but not very active members who were still 'Newbies').


In ./Sources/Display.php

Find:
Code: [Select]
// Do we need to show the visual verification image?
$context['require_verification'] = !$user_info['is_mod'] && !$user_info['is_admin'] && !empty($modSettings['posts_require_captcha']) && ($user_info['posts'] < $modSettings['posts_require_captcha'] || ($user_info['is_guest'] && $modSettings['posts_require_captcha'] == -1));

Replace with:
Code: [Select]
// Do we need to show the visual verification image?
// Code to exclude post verification for specific group IDs and members who joined more than a specific time ago.
$context['require_verification'] = !$user_info['is_mod'] && !$user_info['is_admin'] && !empty($modSettings['posts_require_captcha']) && ($user_info['posts'] < $modSettings['posts_require_captcha'] || ($user_info['is_guest'] && $modSettings['posts_require_captcha'] == -1)) && !$user_info['no_post_captcha'] && !$user_info['bypass_captcha'];



In ./Sources/Load.php

Find:
Code: [Select]
// This is a logged in user, so definitely not a spider.
$user_info['possibly_robot'] = false;

Add After:
Code: [Select]

// Added code to exclude post and PM verification for specific group IDs and members who joined more than a specific time ago.
$groups_no_post_captcha = (!empty($modSettings['groups_no_post_captcha']) ? explode(',', $modSettings['groups_no_post_captcha'], 20) : array(-1));
$no_post_captcha = (in_array($user_settings['id_group'], $groups_no_post_captcha));
$groups_no_pm_captcha = (!empty($modSettings['groups_no_pm_captcha']) ? explode(',', $modSettings['groups_no_pm_captcha'], 20) : array(-1));
$no_pm_captcha = (in_array($user_settings['id_group'], $groups_no_pm_captcha));
$bypass_captcha = (!empty($modSettings['joined_days_no_captcha']) && $modSettings['joined_days_no_captcha'] > 0 && ($user_settings['date_registered'] < strtotime($modSettings['joined_days_no_captcha'] . ' days')));


Find:
Code: [Select]
if (isset($_COOKIE[$cookiename]))
$_COOKIE[$cookiename] = '';

If the Anti-Spam-Links mod is installed the captcha exclusions can also be applied to links as follows:

In ./Sources/Post.php

Find:
Code: [Select]
// Ugly but necessary.
// Takes into account moderation when deciding whether to show the post error.
if((($own_post && $user_info['is_guest']) || (!$own_post && empty($poster_id)) && $modSettings['anti_spam_links_guests'] == 1) || ((($own_post && !$user_info['is_guest']) || !$own_post && !empty($poster_id)) && !empty($modSettings['anti_spam_links_nolinks']) && $posts < $modSettings['anti_spam_links_nolinks']))

Replace With:
Code: [Select]
// Ugly but necessary.
// Takes into account moderation when deciding whether to show the post error.
// Don't include member if they belong to a group ID for whom post captcha doesn't apply or if they are allowed to bypass captcha because of their length of membership.
if ((($own_post && $user_info['is_guest']) || (!$own_post && empty($poster_id)) && $modSettings['anti_spam_links_guests'] == 1) || ((($own_post && !$user_info['is_guest']) || !$own_post && !empty($poster_id)) && !empty($modSettings['anti_spam_links_nolinks']) && $posts < $modSettings['anti_spam_links_nolinks']) && !$user_info['no_post_captcha'] && !$user_info['bypass_captcha'])


Find:

if((($own_post && $user_info['is_guest']) || (!$own_post && empty($poster_id)) && $modSettings['anti_spam_links_guests'] == 1) || ((($own_post && !$user_info['is_guest']) || !$own_post && !empty($poster_id)) && !empty($modSettings['anti_spam_links_nolinks']) && $posts < $modSettings['anti_spam_links_nolinks']))

I developed this tip/trick after I migrated a forum that had +2500 members from vBulletin to SMF - the forum had been in existence for several years and about 450 of the members had paid subscriptions. 

I guess I could have written some SQL to manually increase the post counts of long-term/financial members but this method allows the member's true post count to be shown and is not affected if the "Recount all member post counts" maintenance task is run.
