关于文章发布和编辑的时候预览功能，群里早已经有大神整了出来，这里做了一下整理，并且给列表页也增加了预览功能

（1）在phpcms/modules/content/content.php中增加public_preview2预览方法

//文章发布前预览

    public function public_preview2() {

        $catid = (int)$_GET['catid'];

        $id = intval($_GET['id']);

        !$catid && showmessage('分类不存在','blank');

        if(empty($id)){//未发布文章预览

             extract($_POST['info']);

        }else{//已发布文章预览

            $CATEGORYS = getcache('category_content_'.$this->get_siteid(),'commons');



            if(!isset($CATEGORYS[$catid]) || $CATEGORYS[$catid]['type']!=0) showmessage(L('missing_part_parameters'),'blank');

            define('HTML', true);

            $CAT = $CATEGORYS[$catid];



            $siteid = $CAT['siteid'];

            $MODEL = getcache('model','commons');

            $modelid = $CAT['modelid'];



            $this->db->table_name = $this->db->db_tablepre.$MODEL[$modelid]['tablename'];

            $r = $this->db->get_one(array('id'=>$id));

            if(!$r) showmessage(L('information_does_not_exist'));

            $this->db->table_name = $this->db->table_name.'_data';

            $r2 = $this->db->get_one(array('id'=>$id));

            $rs = $r2 ? array_merge($r,$r2) : $r;



            //再次重新赋值，以数据库为准

            $catid = $CATEGORYS[$r['catid']]['catid'];

            $modelid = $CATEGORYS[$catid]['modelid'];



            require_once CACHE_MODEL_PATH.'content_output.class.php';

            $content_output = new content_output($modelid,$catid,$CATEGORYS);

            $data = $content_output->get($rs);

            extract($data);

        }



        $content = stripcslashes($content);

        $content = '<p style="text-align:center; background:#A63434; line-height:32px; border: solid 1px #CCC; margin-bottom:10px; color:#FFF; font-size:14px;">请注意，以下为文章预览效果，此文章尚未保存，请预览后保存文章。</p>'.$content;

        include template('content','show');

        echo "

        <link href=\"".CSS_PATH."dialog_simp.css\" rel=\"stylesheet\" type=\"text/css\" />

        <script language=\"javascript\" type=\"text/javascript\" src=\"".JS_PATH."dialog.js\"></script>

        <script type=\"text/javascript\">art.dialog({lock:false,title:'预览文章',mouse:true, id:'content_m', content:'<span style=\"color:#FF0000;\">注意：此文章尚未保存，请在预览之后保存文章</span>',left:'100%',top:'100%',width:200,height:50,drag:true, fixed:true});

        function set_time() {

            $('#secondid').html(1);

        }

        </script>";

        exit;

    }

（2）phpcms/modules/content/templates/content_add.tpl.php增加预览按钮
找到

<div class="fixed-but text-c">

添加代码：

<div class="button"><input type="button" value="文章预览" onClick='preview_content2();'></div>

    <script>

        function preview_content2() {

            myform.action = "?m=content&c=content&a=public_preview2&catid=<?php echo $catid;?>&pc_hash=<?php echo $_SESSION['pc_hash'];?>";

            myform.target = "_blank";

            myform.submit();

            myform.action = "?m=content&c=content&a=add";

            myform.target="_self";

        }

</script>

（3）phpcms/modules/content/templates/content_edit.tpl.php增加预览按钮
同样找到

<div class="fixed-but text-c">

之后添加代码：

<div class="button"><input type="button" value="文章预览" onClick='preview_content2();'></div>

    <script>

        function preview_content2() {

            //将 from 提交到预览页

            myform.action = "?m=content&c=content&a=public_preview2&catid=<?php echo $catid;?>&pc_hash=<?php echo $_SESSION['pc_hash'];?>";

            myform.target = "_blank";

            myform.submit();

            //恢复 form 的默认 Action & target

            myform.action = "?m=content&c=content&a=edit";

            myform.target="_self";

        }

    </script>

（4）phpcms/modules/content/templates/content_list.tpl.php增加预览超链接
在116行左右

<a href="javascript：;" onclick="javascript：openwinx('?m=content&c=content&a=edit&catid=<?php echo $catid;?>&id=<?php echo $r['id']?>','')"><?php echo L('edit');?></a> | <a href="javascript：view_comment('<?php echo id_encode('content_'.$catid,$r['id'],$this->siteid);?>','<?php echo safe_replace($r['title']);?>')"><?php echo L('comment');?></a>

修改成：

<a href="javascript：;" onclick="javascript：openwinx('?m=content&c=content&a=edit&catid=<?php echo $catid;?>&id=<?php echo $r['id']?>','')"><?php echo L('edit');?></a> | <a href="javascript：;" onclick="javascript：openwinx('?m=content&c=content&a=public_preview2&catid=<?php echo $catid;?>&id=<?php echo $r['id']?>','')">预览</a> | <a href="javascript：view_comment('<?php echo id_encode('content_'.$catid,$r['id'],$this->siteid);?>','<?php echo safe_replace($r['title']);?>')"><?php echo L('comment');?></a>
