I have an Array $testes that recieves two arrays $variavel1 and $variavel2. Then I set:

$this->set('testes', $testes)

In View How I can Take the values from $variavel1 and $variavel2 ?

I tried $testes['$variavel1']['field'], but I got Undefined Index $variavel1

Practical Example:

Array ( [0] => Array ( [ProcuraProdutoPedOnline] => Array ( [cd_familia] => 3 [ds_familia] => ACESSORIOS ) ) [1] => Array ( [ProcuraProdutoPedOnline] => Array ( [cd_familia] => 1 [ds_familia] => CALCADOS ) )

and

Array ( [0] => Array ( [VwEstPedOnline] => Array ( [cd_seq_pedido] => 2034 ) ) [1] => Array ( [VwEstPedOnline] => Array ( [cd_seq_pedido] => 2038 ) )

And i'm setting $testes like this, $testes = array($variavel1, $variavel2);

  • this wont work like this $testes['$variavel1']['field'] , maybe $testes[$variavel1]['field'] ? Commented May 6, 2015 at 16:40
  • Tira as aspas simples quando tiver uma variável . Commented May 6, 2015 at 16:41
  • Try $testes[0]['ProcuraProdutoPedOnline'] Commented May 6, 2015 at 16:42
  • I already tried all this ! And I got : Undefined Index... With this $testes[$variavel1]['field'], I got this : Use of undefined constant VwEstPedOnline - assumed 'VwEstPedOnline' @PedroLobito, Já tentei de diversas formas ! Inclusive essa que voce me disse, mas não funcionou. Commented May 6, 2015 at 16:46
  • Please be more specific or show some code. What are your examples? $variavel1 and $variavel2? Or 2 examples for $testes? Which value do you want to retrieve from this example? Commented May 6, 2015 at 16:48

I think you first need to know the array structure. Add this to your view and you'll get a list:

echo '<pre>';
print_r($testes);
echo '</pre>';

If the result is empty the problem might be in the place where you add $variavel1 and $variavel2 to the variable $testes...

EDIT 2: By your example Array:

// Result should be 2034
echo $testes['0']['0']['VwEstPedOnline']['cd_seq_pedido'];

EDIT 3 as answer to your question in the comments to this post:

I still don't understand how $variavel1 and $variavel2 are associated. If there is no connection, you don't need to merge them into one array. You can simply use one foreach within another foreach:

In your controller:

$familias = $this->ProcuraProdutoPedOnline->find('all', array(
  'fields' => array('cd_familia', 'ds_familia'),
  'order' => 'cd_familia'));
$this->set('familias', $familias);

$cdSeqPeds = $this->VwEstPedOnline->find('all', array(
  'fields' => 'cd_seq_pedido',
  'order' => 'cd_seq_pedido'));
$this->set('cdSeqPeds', $cdSeqPeds);

And in your view:

foreach ( $familias as $var1 ) {
  echo '<p>'.$var1['ProcuraProdutoPedOnline']['ds_familia'].':</p>';
  echo '<ul>';
  foreach ( $cdSeqPeds as $var2 ) {
    echo '<li>'.$var2['VwEstPedOnline']['cd_seq_pedido'].'</li>';
  }
  echo '</ul>';
}

The result shoul be something like this:

ACESSORIOS:
· 2034
· 2038
CALCADOS:
· 2034
· 2038

If this doesn't answer your question, please make an example (with english variable names) what you want to get exactly and how the two tables are connected/associated...

Isn't empty, the value is there, this is the structure : Array ( [0] => Array ( [0] => Array ( [VwEstPedOnline] => Array ( [cd_seq_pedido] => 2034 ) ) [1] => Array ( [VwEstPedOnline] => Array ( [cd_seq_pedido] => 2038 ) )
Yes, It worked ! But result 2034 comes duplicated and I want to bring all the Array, understand ? All positions. How can I do that ?
foreach ( $testes['0'] as $item ) { echo '<p>'.$item['VwEstPedOnline']['cd_seq_pedido'].'</p>'; }
And If I want the position [1] on the same foreach, is that possible ??? Whats the difference of foreach($variavel as $obj) to foreach($variavel as key=> $obj) ??? Thanks a lot for the help.
No, sorry, I'm out for today, it's late... I gave you multiple hints, please have a look at them. If you currently don't see a solution, please start a new question on Stackoverflow and give a clear (english) example what you have (tables, connections), what you get and what you want to get (with examples)... Good luck! And good night.
