問題描述

<select name="tra_num"><option value="" {$num_tra=="%"?'selected':''}>全部</option>{volist name="list_tra" id="arr_tra" empty="沒有文章"}<option value="{$arr_tra.id}" { {$num_tra} == {$arr_tra.id} ?'selected':''}>{$arr_tra.id}</option>{/volist} </select>

這樣寫雙花括號(hào)無效 從調(diào)試程序中看是以下狀況

<select name="tra_num"><option value="" >全部</option><option value="1" { (7 == 1 ?'selected':'')}>1</option><option value="2" { (7 == 2 ?'selected':'')}>2</option><option value="4" { (7 == 4 ?'selected':'')}>4</option><option value="5" { (7 == 5 ?'selected':'')}>5</option><option value="6" { (7 == 6 ?'selected':'')}>6</option><option value="7" { (7 == 7 ?'selected':'')}>7</option> </select> </div>

問題解答

中文的{吧，還是你改了模板標(biāo)簽了
