Question

I this PHP foreach code properly written?

$colors = $_GET['color'];
$i = 0;
foreach (explode(' ', $colors) as $color) 
{
    $items = $con -> prepare(
        "SELECT * FROM item_descr WHERE color_base1 = :colorbase1");
    $items -> bindValue(":colorbase1", $color[$i]);
    $i++;
}

I cannot get the SQL to work.

I think this should do what you’re asking – you’re generating $color as a variable in the foreach, but you were accessing it as an array.

$colors = explode(' ', $_GET['color']);
foreach ($colors as $color) 
{
    $items = $con -> prepare(
        "SELECT * FROM item_descr WHERE color_base1 = :colorbase1");
    $items -> bindValue(":colorbase1", $color);
}
