Website.

This feels like a common problem, but it’s a difficult one to Google!

As explained in the comment in the code, inserting the value was previously not a problem but stopped working when I added the additional INSERT queries below it.

$user = $_POST['name'];
$night = $_POST['club'];
$query = mysql_query("SELECT day FROM nights WHERE name = '$night'");
$email = $_POST['email'];

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

    $date = getFullDateString($row['day']);
    $date2 = getDateString($row['day']);

}

// this one previously worked but now enters into the database with $user as "Array"
mysql_query("INSERT INTO guestlists (guest, night, date) VALUES('$user', '$night', '$date') ") or die(mysql_error());

$guest1 = $_POST['name1'];
$guest2 = $_POST['name2'];

// these were added later and work fine but seem to have had an effect on the query above
mysql_query("INSERT INTO guestlists (guest, night, date) VALUES('$guest1', '$night', '$date') ") or die(mysql_error());
mysql_query("INSERT INTO guestlists (guest, night, date) VALUES('$guest2', '$night', '$date') ") or die(mysql_error());

foreach ($_POST as $key){
    if (is_array($key)){
        foreach ($key as $key2 => $value){
            mysql_query("INSERT INTO guestlists (guest, night, date) VALUES('$value', '$night', '$date') ") or die(mysql_error());

        }
    }
}

You should rename the guest HTML inputs to guests[] instead of using name again. You have a naming conflict.

You need to fix this in your javascript code:

var name = $("<p><input class='input' type='text' name='guests[]' value='' /></p>");

And in your HTML code:

<input class="input" type="text" name="guests[]" />

After that, your PHP code should handle the guest variable as an array:

$guests = $_POST['guests'];

foreach ($guests as $guest)
{
    mysql_query("INSERT INTO guestlists (guest, night, date) VALUES('$guest', '$night', '$date') ") 
    or die(mysql_error());
}

Note that you don’t need to go guests[1], guests[2], guests[3] etc.
