|---|
| 1886 | MT::App::Comments |
|---|
| 1887 | |
|---|
| 1888 | =head1 SYNOPSIS |
|---|
| 1889 | |
|---|
| 1890 | The application-level callbacks of the C<MT::App::Comments> application |
|---|
| 1891 | are documented here. |
|---|
| 1892 | |
|---|
| 1893 | =head1 METHODS |
|---|
| 1894 | |
|---|
| 1895 | =head2 $app->init |
|---|
| 1896 | |
|---|
| 1897 | Initializes the application and defines the serviceable modes. |
|---|
| 1898 | |
|---|
| 1899 | =head2 $app->init_request |
|---|
| 1900 | |
|---|
| 1901 | Initializes the application to service the request. |
|---|
| 1902 | |
|---|
| 1903 | =head2 $app->do_preview($cgi[, $err]) |
|---|
| 1904 | |
|---|
| 1905 | Handles the comment preview request and displays the preview using |
|---|
| 1906 | the Comment Preview blog template. If C<$err> is specified, the |
|---|
| 1907 | error message is relayed to the user using the Comment Error blog |
|---|
| 1908 | template. |
|---|
| 1909 | |
|---|
| 1910 | =head2 $app->blog |
|---|
| 1911 | |
|---|
| 1912 | Returns the L<MT::Blog> object related to the entry being commented on. |
|---|
| 1913 | |
|---|
| 1914 | =head2 $app->eval_comment |
|---|
| 1915 | |
|---|
| 1916 | Evaluates the comment being posted in a variety of ways and an L<MT::Comment> |
|---|
| 1917 | object is returned. If the comment request is rejected due to throttling, |
|---|
| 1918 | no object is returned and the Comment Pending blog template is displayed. |
|---|
| 1919 | |
|---|
| 1920 | =head2 $app->handle_error |
|---|
| 1921 | |
|---|
| 1922 | Returns an error message to the user using the Comment Error blog template. |
|---|
| 1923 | |
|---|
| 1924 | =head1 APPLICATION MODES |
|---|
| 1925 | |
|---|
| 1926 | =head2 $app->commenter_name_js |
|---|
| 1927 | |
|---|
| 1928 | Returns some JavaScript code that sets the 'commenter_name' variable |
|---|
| 1929 | based on the 'tk_commenter' cookie that is accessible to the comments |
|---|
| 1930 | CGI script. |
|---|
| 1931 | |
|---|
| 1932 | =head2 $app->do_red |
|---|
| 1933 | |
|---|
| 1934 | Handles a commenter URL redirect, where the comment_id points to a |
|---|
| 1935 | L<MT::Comment> object with a URL. The response redirects the user to |
|---|
| 1936 | that URL. The comment must be approved and published. |
|---|
| 1937 | |
|---|
| 1938 | Note: This behavior has been deprecated in favor of using the 'nofollow' |
|---|
| 1939 | plugin. |
|---|
| 1940 | |
|---|
| 1941 | =head2 $app->handle_sign_in |
|---|
| 1942 | |
|---|
| 1943 | Handles the sign-in process for a sign-in request handled by external |
|---|
| 1944 | such authentication APIs as TypeKey and OpenID. |
|---|
| 1945 | |
|---|
| 1946 | =head2 $app->post |
|---|
| 1947 | |
|---|
| 1948 | Mode that handles posting of a new comment. |
|---|
| 1949 | |
|---|
| 1950 | =head2 $app->preview |
|---|
| 1951 | |
|---|
| 1952 | Mode for previewing a comment before posting. |
|---|
| 1953 | |
|---|
| 1954 | =head1 CALLBACKS |
|---|
| 1955 | |
|---|
| 1956 | =over 4 |
|---|
| 1957 | |
|---|
| 1958 | =item CommentThrottleFilter |
|---|
| 1959 | |
|---|
| 1960 | Called as soon as a new comment has been received. The callback must |
|---|
| 1961 | return a boolean value. If the return value is false, the incoming |
|---|
| 1962 | comment data will be discarded and the app will output an error page |
|---|
| 1963 | about throttling. A CommentThrottleFilter callback has the following |
|---|
| 1964 | signature: |
|---|
| 1965 | |
|---|
| 1966 | sub comment_throttle_filter($cb, $app, $entry) |
|---|
| 1967 | { |
|---|
| 1968 | ... |
|---|
| 1969 | } |
|---|
| 1970 | |
|---|
| 1971 | I<$app> is the C<MT::App::Comments> object, whose interface is documented |
|---|
| 1972 | in L<MT::App::Comments>, and I<$entry> is the entry on which the |
|---|
| 1973 | comment is to be placed. |
|---|
| 1974 | |
|---|
| 1975 | Note that no comment object is passed, because it has not yet been |
|---|
| 1976 | built. As such, this callback can be used to tell the application to |
|---|
| 1977 | exit early from a comment attempt, before much processing takes place. |
|---|
| 1978 | |
|---|
| 1979 | When more than one CommentThrottleFilter is installed, the data is |
|---|
| 1980 | discarded unless all callbacks return true. |
|---|
| 1981 | |
|---|
| 1982 | =item CommentFilter |
|---|
| 1983 | |
|---|
| 1984 | Called once the comment object has been constructed, but before saving |
|---|
| 1985 | it. If any CommentFilter callback returns false, the comment will not |
|---|
| 1986 | be saved. The callback has the following signature: |
|---|
| 1987 | |
|---|
| 1988 | sub comment_filter($cb, $app, $comment) |
|---|
| 1989 | { |
|---|
| 1990 | ... |
|---|
| 1991 | } |
|---|
| 1992 | |
|---|
| 1993 | =head1 SPAM PROTECTION |
|---|
| 1994 | |
|---|
| 1995 | Spam filtering (or "Junk" filtering in MT terminology) is handled using |
|---|
| 1996 | the L<MT::JunkFilter> package and plugins that implement them. Please |
|---|
| 1997 | refer to that module for further documentation. |
