我有这个代码(这是工作并将这些变量传递给另一个文件)

            var month = "<?php echo openedMonthbid();?>";
    var user = "<?php echo $_SESSION['member_id'];?>";
    var day = new Array();


    $(':checkbox:checked').each(function(i){
    day.push('`' + $(this).val() + '`');  });
    var count = day.length;

                            $.ajax({
                            type: "POST",
                            url: "sendBidding.php",
                            data : "user="+user+"&days="+day+"&month="+month+"&number=",
                            dataType: "json",

sendBidding.php

$month = $_POST['month'];
$user = $_POST['user'];
$days = $_POST['days'];
$count = $_POST['count'];//if a check 3 values I get '3'


      mysql_query("INSERT INTO $month ($days) VALUES ('1','1','1')");


    $result = true;

    echo json_encode(array("success"=>$result,
                               "datas" => $data,
                                "mon"=>$month));

我想添加与所选天数一样多的值('1')。如何更改 VALUES ('1','1','1') ?

这是生成一系列相同字符串的解决方案。使用array_fill().

$month = $_POST['month'];
$days = $_POST['days'];

// Be sure to whitelist $month and $days before using them in an SQL query!  
// For example, you could store an associative array keyed by month,
// containing lists of the day column names.
$month_table_whitelist = array(
  "month_jan" => array("day1", "day2", "day3", /* etc */),
  "month_feb" => array("day1", "day2", "day3", /* etc */),
  /* etc */
);
if (!array_key_exists($month, $month_table_whitelist)) {
  die("Please specify a valid month.");
}
if (!array_search($days, $month_table_whitelist[$month])) {
  die("Please specify a valid day of month.");
}

$count = $_POST['count'];//if a check 3 values I get '3'

$tuples = array_fill(1, $count, "('1')");

$status = mysql_query("INSERT INTO $month ($days) VALUES ".implode(",", $tuples));
if ($status === false) {
  die(mysql_error());
}

PS:通过将不安全的值 $month 和 $days 直接插入到查询中,您的查询容易受到 SQL 注入的影响。您应该使用白名单方法来确保这些输入与数据库中的真实表名和列名匹配,不要只信任用户输入。

PPS:您应该知道您正在使用 ext/mysql 函数,但这些已被弃用。如果这是一个新应用程序,您应该在投入更多时间使用已弃用的 API 之前开始使用 mysqli 或 PDO。

$count = $_POST['count'];//if a check 3 values I get '3'

$daystatic="('1')";

mysql_query("INSERT INTO $month ($days) VALUES ". $daystatic . str_repeat ( ",$daystatic" , $count-1));
