{dede:channel type='son'} in dedecms, how to get a peer column when there is no sub-column?

Let's first show you a piece of code:

{dede:channelartlist typeid = 3} {dede:field name='typename'/} {dede:channel type='son' noself='yes'} [field:typename/] {/ dede:channel} {/ dede:channelartlist}

This code means to query the sub-column of id 3 and then query the sub-column of the query sub-column. The effect is shown in the figure:

But this will give rise to a problem, that is, if the column does not have a sub-column, it will take its peer column, so how to solve the problem of {dede:channel type='son'} taking the same-level column when there is no sub-column?

It's actually very simple:

Open the: include\ taglib\ channel.lib.php file.

find

If ($type=='son' & & $reidentices0 & & $totalRow==0)

Change to

If ($type=='son' & & $reidentices0 & & $totalRow==0 & & $noself=='')

That's right.
