将多个同名字段保存到数据库PHP

保存它的PHP代码

$cols = $_POST['col'];

$EvenementID = mysql_real_escape_string($_POST['evenementid']);

foreach($cols as $col) {

$Ticketnaam = mysql_real_escape_string($col['ticket']);
$Aantal = mysql_real_escape_string($col['aantal']);
$Prijs = mysql_real_escape_string($col['prijs']);

$sql = "INSERT INTO tbl_Tickets (EvenementID, Ticketnaam, Aantal, Prijs) VALUES('".$EvenementID ."', '{$Ticketnaam}', '{$Aantal}', '{$Prijs}')";


}

HTML代码

<input type="hidden" name="evenementid" value="<?php echo $evenementid; ?>" />

我正试图将这两个块保存到我的数据库中（因此我需要两条记录）。两个区块的均线相同。问题是数据库中只有一条记录

$cols = $_POST['col'];

$EvenementID = mysql_real_escape_string($_POST['evenementid']);

foreach($cols as $col) {

$Ticketnaam = mysql_real_escape_string($col['ticket']);
$Aantal = mysql_real_escape_string($col['aantal']);
$Prijs = mysql_real_escape_string($col['prijs']);

$sql = "INSERT INTO tbl_Tickets (EvenementID, Ticketnaam, Aantal, Prijs) VALUES('".$EvenementID ."', '{$Ticketnaam}', '{$Aantal}', '{$Prijs}')";

$res = mysql_query($sql);//This will execute count($cols) number of times

}

您需要将mysql_查询（$sql）移动到循环中，否则它将只执行foreach循环的最后一次迭代。

您使用的是ajax还是普通表单提交？我们可以看到您的ajax请求代码吗？您需要展示如何创建

myData

！啊，我在代码段中看到它被遗漏了。问题是ajax需要做一个

计数（$cols）

，看看实际有多少列。如果只有一个键，则表示表单的方式有问题。由于

$\u POST

数组中有多个键，因此这将不起作用。如果

$\u POST['col']

是唯一的键，那么这将起到有限的作用。

    if (isset($_POST)){    
$EvenementID = mysql_real_escape_string($_POST['evenementid']);

foreach($_POST as $col) {

$Ticketnaam_1 = mysql_real_escape_string($col[0]['ticket']);
$Aantal_1 = mysql_real_escape_string($col[0]['aantal']);
$Prijs_1 = mysql_real_escape_string($col[0]['prijs']);


$Ticketnaam_2 = mysql_real_escape_string($col[1]['ticket']);
$Aantal_2 = mysql_real_escape_string($col[1]['aantal']);
$Prijs_2 = mysql_real_escape_string($col[1]['prijs']);





$sql = "INSERT INTO tbl_Tickets (EvenementID, Ticketnaam, Aantal, Prijs) VALUES('".$EvenementID ."', '{$Ticketnaam_1}', '{$Aantal_1}', '{$Prijs_1}')";
$sql = "INSERT INTO tbl_Tickets (EvenementID, Ticketnaam, Aantal, Prijs) VALUES('".$EvenementID ."', '{$Ticketnaam_2}', '{$Aantal_2}', '{$Prijs_2}')";


}


}

var myData = $('#ticket-form').serialize();

                        $.ajax({
