如何在phpcms主页上只显示指定的列？

以下代码控制按列id显示哪些列。id根据实际情况在后台查询，subcat函数查看最终的附件说明。按如下方式修改代码:

{ loop subcat（0，0，$ siteid）$ r } { if $ r【& amp；#39;catid & amp#39;】= = 1 | | $ r【& amp；#39;catid & amp#39;】==2} //显示哪些列{ PHP $ num++ }《div class = & quot；箱猫区& quot{if $num%2！= 0 } style = & quot右边距:10px & quot{/if } & gt；& lth5 class = & quot标题1 & quot& gt{ $ r } & lta href = & quot{ $ r } & quotclass = & quot更多&quot& gt更多》》；& lt/a & gt；& lt/H5 & gt；& ltdiv class = & quot内容& quot& gt{ PC:content action = & quot；列表& quotcatid = & quot$ r & quotorder = & quot更新时间desc & quot；拇指= & quot1 & quotnum = & quot1 & quotreturn = & quot信息& quot} { loop $ info $ v } & ltp & gt& ltimg src = & quot{ thumb $ v，90，0 } & quot；宽度= & quot90 & quotstyle = & quot最大宽度:90%&quot/& gt；& ltstrong & gt& lt目标= & quot_ blank & quottitle = & quot{ $ v【& amp；#39;标题和标题。#39;】} & quot{ title _ style（v）} & gt；{ str _ cut（v【& amp；#39;标题和标题。#39;】，28）} & lt；/a & gt；& lt/strong & gt；& ltbr/>；{ str _ cut（v【& amp；#39;描述&amp。#39;】，100）} & lt；/p & gt；{/loop } {/PC } & lt；div class = & quotbk15 hr & quot& gt& lt/div & gt；{ PC:content action = & quot；列表& quotcatid = & quot$ r & quotnum = & quot5 & quotorder = & quotid DESCreturn = & quot信息& quot} & ltul class = & quot列出lh24 f14 & quot& gt{ loop $ info $ v } & lt李& gt& lta href = & quot{ $ v【& amp；#39;url & amp#39;】} & quottarget = & quot_ blank & quottitle = & quot{ $ v【& amp；#39;标题和标题。#39;】} & quot{ title _ style（v）} & gt；{ str _ cut（v【& amp；#39;标题和标题。#39;】，40）} & lt；/a & gt；& lt/李& gt{/loop } & lt；/ul & gt；{/PC } & lt；/div & gt；& lt/div & gt；{ if $ num % 2 = = 0 } & ltdiv class = & quotbk10 & quot& gt& lt/div & gt；{/if} {/if} {/loop}除了指定特定的列之外，我们还可以通过排除特定的列来显示它们。

排除列的方法
