traverse depth info

[Cesco]

Hi,

Is there possibility to have the actual depth on traverse recursion?

Example:

$cane->traverse( 'ownCane', function( $cane ) {
     echo $actual_depth;
});

Sorry, at this moment no, you can do it manually of course:

$level = 0;
$nodes[0]->traverse( 'ownNode', function( $node ) use ( &$level ) {
        $level ++;
        echo $node->name.$level;
} );

But that might not be what you're looking for.
Might be interesting to add as a new feature though.

cheers

Thanks Gabor!

but it's not exactly what i'm looking for because if i have more "sublevel" of "sublevel" i don't know what level the cycle is.

Example

|- Level 1 ($level = 1)

|-- Sub level 1 ($level = 2)

|-- Sub level 2 ($level = 3 wrong)

|--- Sub Sub level 1 ...

|-- Sub level 3  ...

I try to find another solution and waiting for an future update ;)

I found this solution. I know that's orrible :( but it works :) ... I think there's a better way to to this... if someone want to help me... :)

    $property = 'cane';
    $bean = R::load($property,1);

    echo $bean->name.'<br />';

 

    $cats = array();

    $bean->traverse( 'own'.ucwords($property), function( $bean ) use ( &$property )  {

      global $cats;

      $level = 0;

      $cat = new stdClass();

      $cat->id = $bean->id;

      $cat->name = $bean->name;

      $getLevel = function ($bean) use (&$getLevel,&$level,&$cat,&$property) {

        if ($bean) {

          $level++;

          $getLevel($bean->$property);

        }

        else

          $cat->level = $level;

      };

      $getLevel($bean);

      $cats[] = $cat;

    });

Well, it's very creative :)

I will look into this, it's a lacking feature I agree.
Unfortunately, hierarchical queries are only supported by PostgreSQL, so the solution for other databases will always be a bit clunky.

Thanks very much. You have done a great work with RedBeanPHP and I hope you can introduce this feature on next update.
