|---|
| 1750 | |
|---|
| 1751 | MT::App::Comments |
|---|
| 1752 | |
|---|
| 1753 | =head1 SYNOPSIS |
|---|
| 1754 | |
|---|
| 1755 | The application-level callbacks of the C<MT::App::Comments> application |
|---|
| 1756 | are documented here. |
|---|
| 1757 | |
|---|
| 1758 | =head1 METHODS |
|---|
| 1759 | |
|---|
| 1760 | =head2 $app->init |
|---|
| 1761 | |
|---|
| 1762 | Initializes the application and defines the serviceable modes. |
|---|
| 1763 | |
|---|
| 1764 | =head2 $app->init_request |
|---|
| 1765 | |
|---|
| 1766 | Initializes the application to service the request. |
|---|
| 1767 | |
|---|
| 1768 | =head2 $app->do_preview($cgi[, $err]) |
|---|
| 1769 | |
|---|
| 1770 | Handles the comment preview request and displays the preview using |
|---|
| 1771 | the Comment Preview blog template. If C<$err> is specified, the |
|---|
| 1772 | error message is relayed to the user using the Comment Error blog |
|---|
| 1773 | template. |
|---|
| 1774 | |
|---|
| 1775 | =head2 $app->blog |
|---|
| 1776 | |
|---|
| 1777 | Returns the L<MT::Blog> object related to the entry being commented on. |
|---|
| 1778 | |
|---|
| 1779 | =head2 $app->eval_comment |
|---|
| 1780 | |
|---|
| 1781 | Evaluates the comment being posted in a variety of ways and an L<MT::Comment> |
|---|
| 1782 | object is returned. If the comment request is rejected due to throttling, |
|---|
| 1783 | no object is returned and the Comment Pending blog template is displayed. |
|---|
| 1784 | |
|---|
| 1785 | =head2 $app->handle_error |
|---|
| 1786 | |
|---|
| 1787 | Returns an error message to the user using the Comment Error blog template. |
|---|
| 1788 | |
|---|
| 1789 | =head1 APPLICATION MODES |
|---|
| 1790 | |
|---|
| 1791 | =head2 $app->commenter_name_js |
|---|
| 1792 | |
|---|
| 1793 | Returns some JavaScript code that sets the 'commenter_name' variable |
|---|
| 1794 | based on the 'tk_commenter' cookie that is accessible to the comments |
|---|
| 1795 | CGI script. |
|---|
| 1796 | |
|---|
| 1797 | =head2 $app->do_red |
|---|
| 1798 | |
|---|
| 1799 | Handles a commenter URL redirect, where the comment_id points to a |
|---|
| 1800 | L<MT::Comment> object with a URL. The response redirects the user to |
|---|
| 1801 | that URL. The comment must be approved and published. |
|---|
| 1802 | |
|---|
| 1803 | Note: This behavior has been deprecated in favor of using the 'nofollow' |
|---|
| 1804 | plugin. |
|---|
| 1805 | |
|---|
| 1806 | =head2 $app->handle_sign_in |
|---|
| 1807 | |
|---|
| 1808 | Handles the sign-in process for a sign-in request handled by external |
|---|
| 1809 | such authentication APIs as TypeKey and OpenID. |
|---|
| 1810 | |
|---|
| 1811 | =head2 $app->post |
|---|
| 1812 | |
|---|
| 1813 | Mode that handles posting of a new comment. |
|---|
| 1814 | |
|---|
| 1815 | =head2 $app->preview |
|---|
| 1816 | |
|---|
| 1817 | Mode for previewing a comment before posting. |
|---|
| 1818 | |
|---|
| 1819 | =head1 CALLBACKS |
|---|
| 1820 | |
|---|
| 1821 | =over 4 |
|---|
| 1822 | |
|---|
| 1823 | =item CommentThrottleFilter |
|---|
| 1824 | |
|---|
| 1825 | Called as soon as a new comment has been received. The callback must |
|---|
| 1826 | return a boolean value. If the return value is false, the incoming |
|---|
| 1827 | comment data will be discarded and the app will output an error page |
|---|
| 1828 | about throttling. A CommentThrottleFilter callback has the following |
|---|
| 1829 | signature: |
|---|
| 1830 | |
|---|
| 1831 | sub comment_throttle_filter($cb, $app, $entry) |
|---|
| 1832 | { |
|---|
| 1833 | ... |
|---|
| 1834 | } |
|---|
| 1835 | |
|---|
| 1836 | I<$app> is the C<MT::App::Comments> object, whose interface is documented |
|---|
| 1837 | in L<MT::App::Comments>, and I<$entry> is the entry on which the |
|---|
| 1838 | comment is to be placed. |
|---|
| 1839 | |
|---|
| 1840 | Note that no comment object is passed, because it has not yet been |
|---|
| 1841 | built. As such, this callback can be used to tell the application to |
|---|
| 1842 | exit early from a comment attempt, before much processing takes place. |
|---|
| 1843 | |
|---|
| 1844 | When more than one CommentThrottleFilter is installed, the data is |
|---|
| 1845 | discarded unless all callbacks return true. |
|---|
| 1846 | |
|---|
| 1847 | =item CommentFilter |
|---|
| 1848 | |
|---|
| 1849 | Called once the comment object has been constructed, but before saving |
|---|
| 1850 | it. If any CommentFilter callback returns false, the comment will not |
|---|
| 1851 | be saved. The callback has the following signature: |
|---|
| 1852 | |
|---|
| 1853 | sub comment_filter($cb, $app, $comment) |
|---|
| 1854 | { |
|---|
| 1855 | ... |
|---|
| 1856 | } |
|---|
| 1857 | |
|---|
| 1858 | =head1 SPAM PROTECTION |
|---|
| 1859 | |
|---|
| 1860 | Spam filtering (or "Junk" filtering in MT terminology) is handled using |
|---|
| 1861 | the L<MT::JunkFilter> package and plugins that implement them. Please |
|---|
| 1862 | refer to that module for further documentation. |
|---|
| 1863 | |
