Custom Code Function how to set var?

Hi
i am currently trying to set an Array via Custom Code as var. when i print out the Array its ok but how can i access this var from another view?
​
Event:

<h1>Select Team</h1>
{fn:read_years_teams}   <!-- Gets all Teams for year x,y,z (also duplicated values if a team played in season x&z) -->
{fn:clear_years_teams_result} <!-- My Custom Function which takes the read_years_teams var and check for duplicates (code below)-->

{view:repeater_teams_in_years} <!-- Repeater which will create a Card for each team based on the return of fn clear_years_teams-->
{debug:}

fn clear_years_teams_result:
Option to return VAR is set to ON

<?php
$years_teams = $this->get("read_years_teams");
$teamlist = [ ];[li];
foreach($years_teams as $team){
   if(!in_array($team['Team'], $teamlist)){
        $teamlist[ ] = $team['Team'];[/li]
   }
}
/* Debug:
foreach($teamlist as $element){
  echo "".$element["id"]." - ".$element["name"]."<br />";
}
*/
[br]return $teamlist;   // returns an Array of Associative Arrays[br][br]?>

In my Repeater i have the "data provider" Field but when i enter there {var:clear_years_teams_result} nothing happens - also debug does not show anything on the page itself?

OK got it

If you want to return a Value from a Custom Code Element you have to use this Syntax:

$this->data['teamlist'] = $teamlist;

no return statement is needed in my case my custom Code Block looks like that:
and for sure the "VAR Option Only Option is set to YES"
​[pre]<?php
$years_teams = $this->get("read_years_teams");
$teamlist = [];
foreach($years_teams as $team){
if(!in_array($team['Team'], $teamlist)){[br] $teamlist[]=$team['Team'];[br] }[br]}[br]$this->data['teamlist'] = $teamlist;[br]?>[/pre]
​
This returns (in my case) the array $teamlist into the data array of the page:
​

Array
(
    [conn] => safsc
    [target] => table
    [event] => safsc_table_selectTeams
...
    [option] => com_chronoconnectivity6
    [view] => connection
    [teamlist] => Array
        (
            [0] => Array
                (
                    [id] => 1
                    [name] => Calanda Broncos
                    [color] => #be1a1b[br]                    [logo] => broncos.png[br]                    [web] => http://www.calandabroncos.ch[br]                )[br]...

And is now accessible via:

{data:teamlist}

​
Hope that helps also someone else...
​
kind regards
Proximate

{var.set:name$data}
OR
$this->set("name", data);
​
Then available under {var:name}

Or set the custom code block to return var, and whatever you echo or print there is stored in {var:code_block_name}

Strange - in my tests the code Above failed:
​

<?php
$my_php_var = 'Foo';
{var.set:my_var_name$my_php_var}  // Error: syntax error, unexpected 'var' (T_VAR)&nbsp;&nbsp;

?>

Edit:

$this->set('my_var_name', $my_php_var) // Works when called after with {var:my_var_name} but is not shown in debug (?)
