You should structure your comment so it would use the "comment_text" build in function or even easier should use a fallback function that would structure your comment...

例如，在《2010》中，它是这样的：

function twentyten_comment( $comment, $args, $depth ) {
$GLOBALS[\'comment\'] = $comment;
switch ( $comment->comment_type ) :
    case \'\' :
?>
<li <?php comment_class(); ?> id="li-comment-<?php comment_ID(); ?>">
    <div id="comment-<?php comment_ID(); ?>">
    <div class="comment-author vcard">
        <?php echo get_avatar( $comment, 40 ); ?>
        <?php printf( __( \'%s <span class="says">says:</span>\', \'twentyten\' ), sprintf( \'<cite class="fn">%s</cite>\', get_comment_author_link() ) ); ?>
    </div><!-- .comment-author .vcard -->
    <?php if ( $comment->comment_approved == \'0\' ) : ?>
        <em><?php _e( \'Your comment is awaiting moderation.\', \'twentyten\' ); ?></em>
        <br />
    <?php endif; ?>

    <div class="comment-meta commentmetadata"><a href="<?php echo esc_url( get_comment_link( $comment->comment_ID ) ); ?>">
        <?php
            /* translators: 1: date, 2: time */
            printf( __( \'%1$s at %2$s\', \'twentyten\' ), get_comment_date(),  get_comment_time() ); ?></a><?php edit_comment_link( __( \'(Edit)\', \'twentyten\' ), \' \' );
        ?>
    </div><!-- .comment-meta .commentmetadata -->

    <div class="comment-body"><?php comment_text(); ?></div>

    <div class="reply">
        <?php comment_reply_link( array_merge( $args, array( \'depth\' => $depth, \'max_depth\' => $args[\'max_depth\'] ) ) ); ?>
    </div><!-- .reply -->
</div><!-- #comment-##  -->

<?php
        break;
    case \'pingback\'  :
    case \'trackback\' :
?>
<li class="post pingback">
    <p><?php _e( \'Pingback:\', \'twentyten\' ); ?> <?php comment_author_link(); ?><?php edit_comment_link( __(\'(Edit)\', \'twentyten\'), \' \' ); ?></p>
<?php
        break;
endswitch;
}
endif;

wp_list_comments( array( \'callback\' => \'twentyten_comment\' ) );

comment_text()

.
希望这有帮助；）<祝你好运，萨吉夫。
