foreach checkbox

[three]

Hallo Leute!

Estou tentando implementar uma selecao em checkbox para categorias de posts de um blog em CakePHP.

Em resumo, acho que o Cake está escrevendo o valor de cada check box um em cima do outro porque o resultado final na array fornece apenas 1 elemento que os valores variam em 0 e 2, os valores do último checkbox. =´)

Se alguém já passou por algo parecido e tiver alguma dica, será de graaaaaande ajuda.

Abaixo trechos dos códigos do Cake que ajudam a entender o que está acontecendo:

Abracos,

tu queres e que cada check box fique com um valor diferente este valor vem da base de dados?

<form method="post" action="ceck.php">

<?php

while($res = mysql_fetch_assoc($query)){

echo $res['nome'];?><input type=checkbox" name="ceck[]" value="<?php echo $res['valor];?>"/>

<?php } ?>

<label>

<input type="submit" name="Submit" value="Submit" />

</label>

</form>

depois para receber estes dados pode ser assim

<?php

if(empty($_POST['ceck'])){

echo("Por favor selecione um campo");

exit();

}

foreach($_POST['ceck'] as $che){

echo $che;

?>

<br/>

<?php

} ?>
