Hi Thomas,
this is my code for the beforeRender. I got a Class not found error.
Fatal error: Class 'Array2IteratorAggregate' not found.
<?php
function beforeRender() {
App::import('Lib', 'Array2IteratorAggregate');
$iterators = empty($this->viewVars['TwigObjects']
['IteratorAggregate']) ?
array() :
$this->viewVars['TwigObjects']['IteratorAggregate'];
foreach($iterators as $alias) {
$array = empty($this->viewVars[$alias]) ?
array() : $this->viewVars[$alias];
if (is_array($array) AND !empty($array)) {
$this->viewVars[$alias] =
Array2IteratorAggregate::a2ia($array);
$items = $this->viewVars[$alias];
if( !is_array( $items ) && !$items instanceof
Traversable ) {
$this->log('not working');
} else {
$this->log(' working');
}
$this->log($array);
}
}
}
?>
http://bin.cakephp.org/view/1692840979 in case you prefer paste.
my file in app/libs is array_2_iterator_aggregate.php
the code inside that file is found here. http://bin.cakephp.org/view/1592385093
