Question

I am sending a variable with multiple values like this:

JQUERY:

 $(".indexMain").load('indexMain.php?color=' + colors.join("+"), function()

–>
indexMain.php?colors=blue+red+brown

I want to _GET those values and then use them in a while loop to put them into a SQL query like this one:

$items = $con -> prepare("SELECT * FROM item_descr WHERE color_base1 = :colorbase1");
$items -> bindValue(":colorbase1", $color);

Thanks!

EDIT: here is my current code but it is not working, it just shows the items corresponding to the 1st color.

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

    }

Answer 1

indexMain.php?color=blue+red+brown

should be

indexMain.php?colors%5B%5D=blue&colors%5B%5D=red&colors%5B%5D=brown

which is equivalent to

indexMain.php?colors[]=blue&colors[]=red&colors[]=brown

This creates an array accessible with $_GET['colors']. After that use this PHP:

foreach ($_GET['colors'] as $color) {
    $query = $con->prepare("SELECT * FROM item_descr WHERE color_base1 = :colorbase1");
    if ($query->execute(":colorbase1", $color)) {
        // use results from query
    } else {
        // handle failed query
    }
}

If you don’t want to change the query string, you can do this alternatively:

foreach (explode(' ', $_GET['colors']) as $color) {
    $query = $con->prepare("SELECT * FROM item_descr WHERE color_base1 = :colorbase1");
    if ($query->execute(":colorbase1", $color)) {
        // use results from query
    } else {
        // handle failed query
    }
}

Note that the only change is in the first line and we are splitting the string by spaces (because “+” gets converted to a space character).

Also note that both examples assume that $_GET['colors'] is defined. You can use isset() to check if it is defined.
