Question

我简单地解释了我创建了一个表，该表显示了我所有的视频产品，其中包含它的容器内部有两个select，以表格形式包含在内，它们传递值以将表填充到我的数据库中，并且一切正常。尽管唯一的一件事情是，当我选择一个以上的产品时，数据库仅正确地注册了从复选框中选择的最后一个产品，放置我的代码以实现我的目标，即能够插入更多产品（impianto_id_campagna）客户ID（cliente_id_campagna）和事件ID（id_campagna_cliente）：

代码：

<?php
$messaggio = "";
if (isset($_POST['submit'])) {
include '../connessione.php';
$id_campagna_cliente = $connessione->real_escape_string($_POST['id_campagna_cliente']);
$cliente_id_campagna = $connessione->real_escape_string($_POST['cliente_id_campagna']);
$impianto_id_campagna = $connessione->real_escape_string($_POST['impianto_id_campagna']);
$connessione->query("INSERT INTO campagne_cliente (
id_campagna_cliente,
cliente_id_campagna,
impianto_id_campagna) 

VALUES (
'$id_campagna_cliente', 
'$cliente_id_campagna', 
'$impianto_id_campagna')");
$messaggio = "Registrazione Completata!";
}
?>      

 <main>
<?php
include '../connessione.php';
$query_string = "SELECT * FROM store_locator WHERE store_locator.id NOT IN (SELECT impianto_id_campagna FROM campagne_cliente)";
$query = mysqli_query($connessione, $query_string);
?>

<?php
include '../connessione.php';
$query_string = "SELECT * FROM clienti";
$clienti = mysqli_query($connessione, $query_string);
?>

<?php
include '../connessione.php';
$query_string = "SELECT * FROM campagne_cliente
INNER JOIN clienti
ON clienti.cliente_id = campagne_cliente.cliente_id_campagna 
INNER JOIN campagne
ON campagne.id_campagna = campagne_cliente.id_campagna_cliente GROUP BY cognome";
$campagne = mysqli_query($connessione, $query_string);
?>


<!-- Datatables initialization -->
<script>
// Basic example
$(document).ready(function () {
  $('#dtBasicExample').DataTable();
  $('.dataTables_length').addClass('bs-select');
});

Answer 1

它仅注册最后一个选定的产品，因为每个复选框都具有相同的名称属性。将名称设置为impianto_id_campagna[]以便在您的$_POST变量中返回一个数组。

<input type="checkbox" name="impianto_id_campagna[]" class="form-check-input" value="<?php echo $row['id'] ;?>" id="<?php echo $row['id'] ;?>">

然后循环所有复选框值，一次插入一个产品：

<?php
$id_campagna_cliente = $connessione->real_escape_string($_POST['id_campagna_cliente']);
$cliente_id_campagna = $connessione->real_escape_string($_POST['cliente_id_campagna']);

foreach ($_POST['impianto_id_campagna'] as $value)
{
    $impianto_id_campagna = $connessione->real_escape_string($value);

    $connessione->query("INSERT INTO campagne_cliente (
    id_campagna_cliente,
    cliente_id_campagna,
    impianto_id_campagna) 

    VALUES (
    '$id_campagna_cliente', 
    '$cliente_id_campagna', 
    '$impianto_id_campagna')");

    $messaggio = "Registrazione Completata!";
}

Answer 2

复选框项作为数组传递。为了使它们进入数据库，您必须遍历数组并采取相应的措施。

foreach($impianto_id_campagna as $row){
    //Iterate through and do what you need to do with the data.
}

在数据库中多次输入产品-PHP
