    // MY PHP Insert code

    <?php   
    $con = mysql_connect("localhost","root","");
    if (!$con){
    die("Can not connect: " . mysql_error());
    }
    mysql_select_db("SLL",$con);

//please assume boxes = training

    $name = $_POST['name'];
    $training= $_POST['boxes'];

    $AddQuery ="INSERT INTO db (name,training)VALUES ($name,training)"

   mysql_query($AddQuery, $con);
    ?>

Nearly there (apart from the odd typo), $_POST['boxes'] is an array, so just foreach loop (explanation) through each key in the array. $_POST['boxes']几乎位于那里（除了奇数的错字），是一个数组，因此只需要遍历数组中的每个键进行foreach循环（解释）即可。

<?php   
    $con = mysql_connect("localhost","root","");
    if (!$con){
    die("Can not connect: " . mysql_error());
    }
    mysql_select_db("SLL",$con);

    $name = $_POST['name'];

//please assume boxes = training
    foreach($_POST['boxes'] as $textbox){
        $training= $textbox;
        $AddQuery ="INSERT INTO db (name,training)VALUES ($name,$training)";
        mysql_query($AddQuery, $con);

    }
?>

UPDATE To loop through with two or more input arrays, ie name="boxes[]" and name="amount[]" , it will need to be assumed that each boxes[] is relative to amount[] , ie boxes[0] goes with amount[0] , boxes[1] goes with amount[1] , boxes[n] goes with amount[n] . 更新要遍历两个或多个输入数组，即name="boxes[]"和name="amount[]" ，需要假设每个boxes[]相对于amount[] ，即boxes[0]与amount[0] boxes[1] ， boxes[1]与amount[1] boxes[n] ， boxes[n]与amount[n] 。 So, you will need a counter that increments every time the loop ends/restarts. 因此，您将需要一个计数器，该计数器每次循环结束/重新启动时都会增加。 See $i , you will see that the value of $i is being increased by 1 at the end of each go round the loop, and this is caught by the amount by key as $_POST['amount'][$i] . 看到$i ，您将看到$i的值在每次循环结束时都增加1，并且被键$_POST['amount'][$i]的金额所捕获。

The revised loop would be something like 修改后的循环类似于

$i = 0; 
foreach($_POST['boxes'] as $textbox){
    $training= $textbox;
    $amount = $_POST['amount'][$i];
    $AddQuery ="INSERT INTO db (name,training,amount)VALUES ($name,$training,$amount)";
    mysql_query($AddQuery, $con);
    $i++;
}
