I'm not sure why I can't sort in the Statistics -> Users Online screen, but it was driving me crazy each time I used it. In anycase, this is what I did to sort it by "Last Entry" Date:
Create a new file called
modifier.sortby.php with the following code, and place it in your
\include\lib\smarty\plugins\ folder.
PHP Code:
<?php
#
# sorts an array of named arrays by the supplied fields
# code by dholmes at jccc d0t net
# taken from http://au.php.net/function.uasort
# modified by cablehead, messju and pscs at http://www.phpinsider.com/smarty-forum
function array_sort_by_fields(&$data, $sortby){
static $sort_funcs = array();
if (empty($sort_funcs[$sortby]))
{
$code = "\$c=0;";
foreach (split(',', $sortby) as $key)
{
$d = '1';
if (substr($key, 0, 1) == '-')
{
$d = '-1';
$key = substr($key, 1);
}
if (substr($key, 0, 1) == '#')
{
$key = substr($key, 1);
$code .= "if ( ( \$c = (\$a['$key'] - \$b['$key'])) != 0 ) return $d * \$c;\n";
}
else
{
$code .= "if ( (\$c = strcasecmp(\$a['$key'],\$b['$key'])) != 0 ) return $d * \$c;\n";
}
}
$code .= 'return $c;';
$sort_func = $sort_funcs[$sortby] = create_function('$a, $b', $code);
}
else
{
$sort_func = $sort_funcs[$sortby];
}
uasort($data, $sort_func);
}
#
# Modifier: sortby - allows arrays of named arrays to be sorted by a given field
#
function smarty_modifier_sortby($arrData,$sortfields) {
array_sort_by_fields($arrData,$sortfields);
return $arrData;
}
$smarty->register_modifier( "sortby", "smarty_modifier_sortby" );
?>
Next, locate the following line in
\skin1\modules\Users_online\stats.tpl:
PHP Code:
{foreach from=$statistics item=v}
Change it to this:
PHP Code:
{foreach from=$statistics|@sortby:"-current_date" item=v}
That's it. This will sort the "Users online" by last entry date in descending order. If you want it in ascending order, just remove the minus sign or replace it with a # sign. You can sort by multiple fields by separating them with a comma.
