Question

织梦判断字段是否为空

{dede:field name='down_pic1' runphp='yes'}
if(@me=='') {
@me = '' ;
}
else {
@me = "<div class='pic'><img src='{dede:field.down_pic5/}' id='showImg6'></div>";
}
{/dede:field}

@me = "<div class='pic'><img src='{dede:field.down_pic5/}' id='showImg6'></div>"; 这个输出来是输不出{dede:field.down_pic5/}
我想知道怎么输出来？

Answer 1

{dede:field name='down_pic1' runphp='yes'}
if(@me=='') {
@me = '' ;
}
else {
@me = "<div class='pic'><img src='.@me.' id='showImg6'></div>";
}
{/dede:field}

dede大多数标签是不嵌套的，仅channelartlist
