Answer 1

$insStr = '';
foreach($_POST['addons'] as $val){ $insStr .=$val.","; }
mysql_query("INSERT INTO promos (promo) VALUES ( '$insStr' )");

Answer 2

You can use serialize() method
example
$arr = Array ( [0] => 1 [1] => 2 [2] => 3);
$str = serialize($arr);
After retrieving from database use unserialize() method

Answer 3

You can take advantage of PHP built-in function named implode
Example
$checkboxValue implode(',',$_POST['addons']);

Answer 4

Try like this
if(!empty($_POST['addons'])) { $addons_string="";foreach($_POST['addons'] as $addon){$addons_string.=$addon.","; } }

Answer 5

test.php
<form name="test" action="test1.php" method="get">
<?php
for($i=0; $i<9;$i++){
echo "<input type='checkbox' name=a[] value=$i>$i<br>";
}
?>
<input type="submit" value="Submit">
</form>
and test1.php
<?php
foreach($_GET['a'] as $check) {
echo $check;
//SAVE VALUES TO DATABASE
}
?>
