php判断:在指定日期之后触发事件(完美使用新@功能)
首先给个例子,我今天找到一个让回复中加@功能的新方法,利用add_filter而非js,这个方法好处多多,避免了js冲突(如分页功能下)@失效的BUG. add_filter('comment_text','comment_add_at_parent');function comment_add_at_parent($comment_text){$comment_ID = g
首先给个例子,我今天找到一个让回复中加@功能的新方法,利用add_filter而非js,这个方法好处多多,避免了js冲突(如分页功能下)@失效的BUG.
add_filter('comment_text','comment_add_at_parent'); function comment_add_at_parent($comment_text){ $comment_ID = get_comment_ID(); $comment = get_comment($comment_ID); if ($comment->comment_parent ) { $parent_comment = get_comment($comment->comment_parent); $comment_text = '<a href="#comment-'%20.%20%24comment->comment_parent%20.%20'">@'.$parent_comment->comment_author.'</a> ' . $comment_text; } return $comment_text; }
但这个方法有个小弊端,就是它会给所有子评论加上@,而以前用js时访客在评论内容中输入的@还存在于评论内容中, 这就导致旧评论中会出现双@.
解决这个问题的办法就是让指定日期之前的评论不受此函数影响,也就是我们今天要讨论的话题:利用php判断来使事件在指定日期之后触发.
比如今天是2013年3月17日,我今天给主题加上了上述函数,所以我希望这个函数不对2013年3月17日之前的评论起作用,所以我们可以将其改成如下代码:
add_filter('comment_text','comment_add_at_parent'); function comment_add_at_parent($comment_text){ $comment_ID = get_comment_ID(); $comment = get_comment($comment_ID); $date = mysql2date( 'Ymd',$comment->comment_date) ;//通过mysql2date函数将评论时间日期化,即转为无时间的日期格式,这里的Ymd表示日期格式为"年月日",中间没有分隔符,这很重要,下一行会提到 if( $date > 20130317) {//判断: 如果评论日期大于指定日期,也就是在指定日期之后,则输出下面的函数 (这里就是为什么要用Ymd的格式,因为没有分隔符,可以将其当作纯数字来运算),20130317可以改成你需要的指定日期 if ($comment->comment_parent ) { $parent_comment = get_comment($comment->comment_parent); $comment_text = '<a rel="nofollow" href="#comment-'%20.%20%24comment->comment_parent%20.%20'">@'.$parent_comment->comment_author.'</a> ' . $comment_text; } } return $comment_text; }
最后说一句,有东西折腾真好啊,好久没有文荒的感觉了,好开森.
