I looked at phpcms today and found a problem when writing the secondary navigation. When querying the navigation bar information, the $r[arrchildid] returned was not consistent with what I imagined. The document said that the sub-column id was returned, but it was somewhat different.

Things to start with:

General idea: Query whether there is a sub-column ID under the document, and if so, output the secondary navigation. Line 5 in the code is to detect whether there is a sub-column ID under the column, but I found that when there is no sub-column, the ID of the current column will be returned, which makes the judgment unable to achieve the expected effect, so I changed my mind and the code is as follows:

<span style="color: #008080;"> 1</span>  <ul <span style="color: #0000ff;">class</span>=<span style="color: #800000;">"</span><span style="color: #800000;">nav navbar-nav</span><span style="color: #800000;">"</span>>

Determine whether the obtained sub-column id is equal to the column id. If it is equal, it means there is no sub-column. If it is not equal, it means there is a sub-column and the sub-column is displayed
