Question

我有foreach循环，无法将数据插入db。如果我将插入语句移出循环，则可以正常工作，但仅适用于1个项目。同样，回声不返回任何数据。如果有人可以检查我的代码并指出我的错误，我将不胜感激。

假定所有连接都已建立，并且所有$ _POST值正确。非常感谢

<?php
    session_start();
    include($_SERVER['DOCUMENT_ROOT'] . '/lsorg/users/Connections/ls.php');

    $company = strtoupper(mysqli_real_escape_string($conn, $_SESSION['ls_idcode_usr']));
    $activity = "Box Return";
    $address = ucwords(mysqli_real_escape_string($conn, $_POST['address']));
    $service = ucwords(mysqli_real_escape_string($conn, $_POST['service']));
    $success = 'SUCCESS';
    $authorised = mysqli_real_escape_string($conn, $_SESSION['ls_name_usr']);
    $dept = strtoupper(mysqli_real_escape_string($conn, $_POST['dept']));
    $boxitems = $_POST['sub'];
    $box = implode(",",$boxitems);
    $array = array();
    $array = $boxitems;


    foreach ($array as $boxes) {
        $outString .= "$box" . "  ";

        //$boxitem = $box;

        $sql = "INSERT INTO act 
                        (service, activity, department, 
                         company, address, user, 
                        `date`, item, new) 
                VALUES ('".$service."', '".$activity."', '".$dept."', 
                        '".$company."', '".$address."', '".$authorised."', 
                        NOW(), '".$boxes."', '1')";
        $result = mysqli_query($conn, $sql) or die ('Error inserting box:' . mysqli_error());


    }
    echo $outString;
    mysqli_close($conn); // Connection Closed
?>

添加调试代码后

警告：implode（）[function.implode]：在第16行的C：\ wamp \ www \ lsorg \ users \ brtn.php中传递了无效的参数警告：为C：\ wamp \中的foreach（）提供了无效的参数www \ lsorg \ users \ brtn.php在第22行string（10）“ DEMOBOX050”注意：未定义变量：C：\ wamp \ www \ lsorg \ users \ brtn.php在第39行的outString

回复$_POST['sub']

中的内容

DEMOBOX044,DEMOBOX050

您的变量不正确。

编辑为@RiggsFolly敏锐的眼睛！（爆破->爆炸）

查看代码：

// OLD: $boxitems = implode(",", $_POST['sub']);
$boxitems = explode(",", $_POST['sub']);

foreach ($boxitems as $box) {
  $outString .= "$box" . "  ";
  ...

不需要所有这些。

$boxitems = $_POST['sub'];
$box = implode(",",$boxitems);
$array = array();
$array = $boxitems;

foreach循环未将值插入mysql
