Question

我尝试使用循环和带句柄的UPDATE函数一次编辑多个条目。但是条目正确，但数据库没有变化。当我进行单一编辑时，此代码可以正常工作。

<?php include 'header.php'; ?>

<div id="container4"><?php
require ("dbfunction.php");
$con = getDbConnect();


$checkbox2 = $_POST['checkbox2'];

if (!mysqli_connect_errno($con)) {
    $str = implode($checkbox2);

    $queryStr = "SELECT * " .
            "FROM crewlist WHERE  ($str) && crew_id";
}

$result = mysqli_query($con, $queryStr);


    $checkbox2 = $_POST['checkbox2'];
    foreach ($checkbox2 as $crewname) {

        ?> <form action="handlemultiedit.php" method="post">
            <input type="hidden" name="crew_id" value="<?php echo $id = isset($_GET['id']) ? $_GET['id'] : ''; ?>" />
        <?php echo "<tr><th>" . $crewname . ":</th><br>";
        echo "                    <tr>
                    <td>Shift 1:</td>
                    <td><input type=\"time\" name=\"start_hour\" value=\"start_hour\" id=\"start_hour\" step=\"1800\" required> to <input type=\"time\" name=\"end_hour\" value=\"end_hour\" id=\"end_hour\" step=\"1800\" required>
                    </td>       
                </tr>
                <tr>
                    <td>Shift 2:</td>
                    <td><input type=\"time\" name=\"start_hour2\" value=\"start_hour2\" id=\"start_hour2\" step=\"1800\" required> to <input type=\"time\" name=\"end_hour2\" value=\"end_hour2\" id=\"end_hour2\" step=\"1800\" required>
                    </td>       
                </tr><br><br>";
        ?><?php
    }?><td><input type="submit" value="Submit" ></td></form><?php

?>

这是句柄页面

<?php

print_r($_POST);
require 'dbfunction.php';
$con = getDbConnect();
$crew_id = $_POST["crew_id"];
$start_hour = $_POST["start_hour"];
$end_hour = $_POST["end_hour"];
$start_hour2 = $_POST["start_hour2"];
$end_hour2 = $_POST["end_hour2"];


if (!mysqli_connect_errno($con)) {
$sqlQueryStr = "UPDATE crewlist SET start_hour = '$start_hour',end_hour = '$end_hour', start_hour2 = '$start_hour2',end_hour2 = '$end_hour2' WHERE crew_id = " . $crew_id . "";
mysqli_query($con, $sqlQueryStr);
}


//header('Location: crewlisting.php');
mysqli_close($con);
?>

多个编辑功能数据库未更新
