ONEFORALL - Group sorting bug

[CodeALot]

If you use field type GROUP in OneForAll and SHOW GROUP HEADERS on, SORT BY GROUP on, the sorting goes wrong once you use more than 10 groups.
Sorting is done like:

1
10
11
2
3
4
5 --- etc.
 
Does anyone have a brilliant idea how to solve this?

Hi, try this. Find in view_overview.php the block.

Code: [Select]

// If a group field is defined order by group and position
Last line of this block is

Code: [Select]

          .'ORDER BY `f`.`value` '.$group_order.', `i`.`position` '.$position_order.$limit_sql;
Change it to

Code: [Select]

          .'ORDER BY LENGTH(`f`.`value`), `f`.`value` '.$group_order.', `i`.`position` '.$position_order.$limit_sql;

Only this is added: LENGTH(`f`.`value`),
Hope it helps.

You're the best. That solved it. MANY thanks!

If it is certain that 'f.value' contains a number (integer), it is easier to evaluate this value in the sorting as a number.
This can be achieved with the SQL function CAST(expression AS datatype)'.

Code: [Select]

  .'ORDER BY CAST(`f`.`value` AS UNSIGNED) '.$group_order.', `i`.`position` '.$position_order.$limit_sql;
