When I saw the regional cascading menu of phpcms, I thought it was quite interesting, so I just talked about the general steps to avoid forgetting it.
The generation of regional cascading menus is generally in the areaid() function of the /data/cache_model/content_form.class.php file. However, this is just a cache and I haven’t found where it was generated yet, so it’s just a test for now. (Students who know tell me! Thank you very much)

Copy code The code is as follows:
function delChild(num)
{
$('#load_$field select').each(function(i,obj){
if (obj.id >num)
$('#' obj.id).remove();
})
}
correspondingly, in /load. Modify elseif($field == 'areaid' && $value) in php {
$('#load_$field select').each(function(i,obj){
if (obj.id >num)
$('#' obj.id).remove();
})
}
Copy code The code is as follows:
$str =
'
can remove the effect of "the selected area cannot be changed", and the redundant selection box will not be deleted when there are no subordinate place names. '
As for the traditional cascading menu, I personally feel that the transmission data is relatively large, and the connection with the database does not seem to be good, so I will not post the code.
