How to do sorting of menu tree A-Z and 1,2,...,10,11,...

[q2apro]

I am sorting by the doc alias, as described here: https://github.com/evolution-cms/evolution/issues/260 which works nicely:

However, as you can see, it sorts not natural: 1, 10, 11, 12, 13. ... 2, 20, ...

How to fix this?

Its sort by A-Z all correct. We a sort text not numbers

[q2apro]

I know, but is there any "workaround" (hack) to sort A - Z and 1, 2, ... 10, ...?

Here is a workaround: add a "0" in front of a 1,2,3... ;)

more specific: A workaround without changing the numbers :P

Need find solution order by text+numeric

[q2apro]

In PHP it is called natural sort: https://www.php.net/manual/en/function.natsort.php

Or using usort: https://stackoverflow.com/q/12426825/1066234

Okay, I got it working for my case.

1. Open file manager\frames\nodes.functions.inc.php

2. Go to lines:

    // Folder sorting gets special setup ;) Add menuindex and pagetitle
    if ($_SESSION['tree_sortby'] == 'isfolder') {
        $orderby .= ', menuindex ASC, pagetitle';
    }

3. Afterwards insert this code:

   // hack for natural sorting
   if ($_SESSION['tree_sortby'] == 'alias') {
       // $orderby is "sc.alias ASC"
       $orderby = 'IF(CONCAT("",sc.alias*1)=sc.alias, LPAD(sc.alias,5,"0"), sc.alias) ASC';
   }

The "order by" explained:

• CONCAT("",sc.alias*1)=sc.alias checks for numeric value
• if numeric, then LPAD(sc.alias,5,"0") adds several 0 in front (left padding), which creates 00001, 00010. 00200 etc.
• if not numeric, default sorting

Result:
