Typecho回复可见教程

步骤一

<?php
$db = Typecho_Db::get();
$user = Typecho_Widget::widget('Widget_User');
/*判断用户登录*/
if($user->uid > 0){
/*查询用户的id是否在评论表中*/
$sql = $db->select()->from('table.comments')
    ->where('cid = ?',$this->cid)
    ->where('authorId = ?', $user->uid)
    ->where('status = ?', 'approved')
    ->limit(1);
}else{
/*查询游客的邮箱是否在评论表中*/
$sql = $db->select()->from('table.comments')
    ->where('cid = ?',$this->cid)
    ->where('mail = ?', $this->remember('mail',true))
    ->where('status = ?', 'approved')
    ->limit(1);
}
$result = $db->fetchAll($sql);
/*文章作者和评论过的用户或者游客可以看见回复可见内容*/
if($user->uid==$this->authorId || $result) {
    $content = preg_replace("/\[hide\](.*?)\[\/hide\]/sm",'<div class="reply2view">$1</div>',$this->content);
}
else{
    $content = preg_replace("/\[hide\](.*?)\[\/hide\]/sm",'<div class="reply2view">此处内容需要评论回复后方可阅读。</div>',$this->content);
}
echo $content 
?>

步骤二

解决缩略内容和feed暴露问题。

在functions.php中加入如下代码即可

Typecho_Plugin::factory('Widget_Abstract_Contents')->excerptEx = array('myyodux','one');
Typecho_Plugin::factory('Widget_Abstract_Contents')->contentEx = array('myyodux','one');
Typecho_Plugin::factory('admin/write-post.php')->bottom = array('myyodux', 'san');
Typecho_Plugin::factory('admin/write-page.php')->bottom = array('myyodux', 'san');
class myyodux {
    public static function one($con,$obj,$text)
    {
      $text = empty($text)?$con:$text;
      /*非文章页面，其他显示缩略内容的地方均隐藏内容，并输出‘需回复可见’*/
      if(!$obj->is('single')){
      $text = preg_replace("/\[hide\](.*?)\[\/hide\]/sm",'需回复可见',$text);
      }

               return $text;
}
/*向后台编辑器插入回复可见按钮*/
public static function san()
    {
    ?>
<style>.wmd-button-row {height: auto;}</style>
<script>
$(document).ready(function(){
$('#wmd-button-row').append('<li class="wmd-button" id="wmd-jrotty-button" title="回复可见"><span style="background: none;font-size: 16px;border: 1px solid #dedede;padding: 2px;color: #467B96;width: auto;height: auto;">回复可见</span></li>');
if($('#wmd-button-row').length !== 0){
$('#wmd-jrotty-button').click(function(){
var rs = "[@hide]回复可见内容{/hide}"; //去掉@
var myField = $('#text')[0];
insertAtCursor(myField,rs);
})
}
function insertAtCursor(myField, myValue) {
            //IE 浏览器  
            if (document.selection) {  
                myField.focus();  
                sel = document.selection.createRange();
                sel.text = myValue;  
                sel.select();  
            }
             //FireFox、Chrome等  
            else if (myField.selectionStart || myField.selectionStart == '0') {  
                var startPos = myField.selectionStart;  
                var endPos = myField.selectionEnd; 
                // 保存滚动条  
              var restoreTop = myField.scrollTop;  
                myField.value = myField.value.substring(0, startPos) + myValue + myField.value.substring(endPos, myField.value.length);  
                if (restoreTop > 0) {myField.scrollTop = restoreTop;}  
                myField.focus();  
                myField.selectionStart = startPos + myValue.length;  
                myField.selectionEnd = startPos + myValue.length;
            } else {  
                myField.value += myValue;
                myField.focus();
            }  
        }
});
</script>
<?php
    }
}

就是用插件接口，在缩略内容输出之前，隐藏掉或者替换掉回复可见内容，同时使用if判断，来针对非single页面进行隐藏。

步骤三

使用方法

在写文章需要隐藏部分内容时用以下写法(去掉@)

[@hide]要隐藏的内容{/hide}

css参考样式

.reply2view {
    background:#f8f8f8;
    padding:10px 10px 10px 40px;
    position:relative
}
