                                            <?php
                                            if("{king:up/}"=="1"){
                                                echo "<tr><th>活动价格:</th><td>{king:price/}</td></tr>";
                                                echo "<tr><th>参加人数:</th><td>";                                             
                                                echo "{king:dbquery query='SELECT COUNT(gb.userid)AS calnumber FROM king_groupbuy gb JOIN king__shop s ON gb.productID=s.kid WHERE gb.category=0 AND gb.ndate>UNIX_TIMESTAMP(s.k_nstart) AND s.kid=(king:kid/)'}{king:calnumber/}{/king:dbquery}";                                                
                                                echo "</td></tr><tr><th>活动开始:</th><td>{king:_nstart/}</td></tr>";
                                                echo "<tr><th>活动结束:</th><td>{king:_nfinish/}</td></tr>";
                                                echo "<tr><td colspan="2" id="limitad_{king:kid/}"></td></tr>";
                                                echo "<script type="text/javascript" src="{config:system.siteurl/}{config:system.inst/}images_new/1.js"></script>";                                               
                                            }else{
                                                echo "<tr><th>本店价格:</th><td>{king:price/}</td></tr>";
                                                echo "<tr><th>基本参数:</th><td>&nbsp;</td></tr>";
                                                echo "<tr><td colspan=2>{king:description/}</td></tr>";
                                            }
                                            ?>
