Answer 1

Ok, let's get this straight
You want checkboxes, right! I mean, check!
The nameA column is unique or primary, no duplicates!
the logic and template together
<?php
try {
$host = "xxxx";
$user ="xxx";
$password = "xxx";
$dbname = $user;
$db = new PDO("mysql:host=$host;dbname=$dbname",$user,$password);
$db->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION);
$q = "SELECT nomeA FROM Disponivel";
$options = array();
$count = 0;
foreach($db->query($q) as $row) {
$count++;
$options[$row['nomeA']] = '<input type="checkbox" name="dispo[]" value="'.$row['nomeA'].'" />';
}
echo '<p>Rows processed: '.$count.'</p>';
$db = null;
} catch (PDOException $e) {
echo '<p>ERROR: '.$e->getMessage().'</p>';
}
?>
<form action="addPratosEnc4.php" method="POST">
*Pratos a Adicionar:
<?php
if (!$options) echo ' agora no hay pratos';
else foreach ($options as $name => $input) echo '<label>'.$input.' '.$name.'</label><br />';
?>
<br />
<br />
<button type="submit">Disponibilizar</button>
</form>
Try this, ask any questions if you have them and if any solutions worked for you, please mark them as answer

Answer 2

To render the option list you do:
.......
$nomeA = $row['nomeA'];
/*should be here?*/
?> <option value="<?php echo $nomeA; ?>"><?php echo $nomeA; ?></option><?php
}
$db = null;
}
........
This should create a option list within the select that is filled with the results from the query. I assume you meant an option list not checkboxes -
A select box gives you each option and you can only select 1. You could also do this with radiobuttons. On the other hand you may have meant to use Checkbox's where the user can select multiple boxes.
In this case you shouldnt wrap anything in the select just something like
<input type="checkbox" name="group" value="<?php echo $nomeA; ?>">I have a <?php echo $nomeA; ?><br>
within the for loop.
Good Luck

Answer 3

echo'<input type ="checkbox" name = "'.$row['nomeA'].'"value = "'.$row['nomeA'].'" />'.$row['nomeA'].'<br />;
instead of :
$nomeA = $row['nomeA'];
remove the select tag and that should work.

Answer 4

just to complete my task, i will post what its need to get the values selected:
<?php
session_start();
$email = $_SESSION['email'];
$nEnc = $_SESSION['nEnc'];
$options = $_REQUEST['dispo'];
echo("<p>$email</p>");
echo("<p>$nEnc</p>");
try
{
$host = "xxxx";
$user ="xxxx";
$password = "xxxx";
$dbname = $user;
$db = new PDO("mysql:host=$host;dbname=$dbname", $user, $password);
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
foreach($options as $name){
$nomeA = $name;
$sql = "INSERT INTO RegistoEnc VALUES ('$email',$nEnc,'$nomeA');";
echo("<p>$sql</p>");
$db->query($sql);
};
$db = null;
}
catch (PDOException $e)
{
echo("<p>ERROR: {$e->getMessage()}</p>");
}
echo "<br>Encomenda Criada!!<br>";
?>
