Phpcms V9 Add level two navigation ideas

Today read Phpcms write to level two navigation when found point problem, query navigation bar information returned when the $r[arrchildid] and their imagination, the document is returned sub-column ID but a little different.

The beginning of the idea:

Home

{pc:content action= "category" catid= "0" num= "siteid=" $siteid "order=" Listorder ASC "} {Loop $data $r} {if $r [Arrchildid]} {$r [catname]} {pc:content action= "category" catid= "$r [catid]" num= "siteid=" $siteid "order=" Listorder ASC "return=" Data2 "} {Loop $data 2 $v} {$v [catname]} {/loop} {/PC} {/if} {/loop} {/PC}

General idea: Query whether there is a sub-column ID under the document, if any, output level two navigation. The 5th line in the code is to detect if there is a sub-column ID in the column, but I found that when there is no sub-column will return the current column ID resulting in the judgment can not achieve the desired effect, so change the idea, the code is as follows:

Home

{pc:content action= "category" catid= "0" num= "siteid=" $siteid "order=" Listorder ASC "} {Loop $data $r} {if $r [arrchildid]! = $r [CATID]} {$r [catname]} {pc:content action= "category" catid= "$r [catid]" num= "siteid=" $siteid "order=" Listorder ASC "return=" Data2 "} {Loop $data 2 $v} {$v [catname]} {/loop} {/PC} {Else} {$r [catname]} {/if} {/loop} {/PC}

Determines whether the obtained sub-column ID is equal to the column ID, is equal to the absence of sub-columns, does not mean that there are sub-columns and display sub-columns
