Question

我想允许用户上传他们的图片以制作一个灯箱。因此，我需要将一列中的多个图像存储到数据库中，并将这些图像附加到SELECT SUM(AggTotal) AggTotal,GLAccount FROM ( select amount_split1 as AggTotal, account as GLAccount, expheaderid -- <-- add this column from Expenses union all select amount_split2 as AggTotal, account2 as GLAccount , expheaderid from Expenses ) t1 where expheaderid = 57 GROUP BY GLAccount中。

我认为我必须为每个图像分配一个唯一的键，但是我不知道该怎么做。

| AggTotal | GLAccount | |----------|-----------| | 0 | 0 | | 5.9 | 70410 | | 261.36 | 80400 | | 30 | 80401 | | 105 | 80402 | | 277.96 | 80440 | | 67.35 | 80870 |返回以下错误：

致命错误：未捕获的PDOException：SQLSTATE [HY000]：C：\ xampp \ htdocs \ SAE \ yaute_love \ content \ account.php：190中的常规错误：堆栈跟踪：＃0 C：\ xampp \ htdocs \ SAE \ yaute_love \ content \ account.php（190）：PDOStatement-> fetchAll（2）＃1 C：\ xampp \ htdocs \ SAE \ yaute_love \ index.php（38）：include（'C：\ xampp \ htdocs ...' ）＃2 {main}在第190行的C：\ xampp \ htdocs \ SAE \ yaute_love \ content \ account.php中抛出

这是数据库：

对于初学者来说，此代码看起来不正确...

$files = $_FILES;
$count = count($_FILES['image-user']['name']);
for ($i = 0; $i < $count; $i++) {
    $_FILES['image-user']['name']= $files['image-user']['name'][$i];
    $_FILES['image-user']['type']= $files['image-user']['type'][$i];
    $_FILES['image-user']['tmp_name']= $files['image-user']['tmp_name'][$i];
    $_FILES['image-user']['error']= $files['image-user']['error'][$i];
    $_FILES['image-user']['size']= $files['image-user']['size'][$i];
};

您可能是想让它看起来像这样...

$files = $_FILES;
$count = count($_FILES['image-user']['name']);
for ($i = 0; $i < $count; $i++) {
    $files['image-user']['name'][$i]= $_FILES['image-user']['name'];
    $files['image-user']['type'][$i]= $_FILES['image-user']['type'];
    $files['image-user']['tmp_name'][$i]= $_FILES['image-user']['tmp_name'];
    $files['image-user']['error'][$i]= $_FILES['image-user']['error'];
    $files['image-user']['size'][$i]= $_FILES['image-user']['size'];
};

这也许有些道理，但是很奇怪的是，在循环之后的任何地方都没有使用$ files！

可能还有其他一些问题-特别是如果您不熟悉PHP并从其他地方修改代码。

好吧，我明白了。

PHP：

<?
    function reArrangeFiles($arr) {
        foreach($arr as $key => $all) {
            foreach($all as $i => $val) {
                $new[$i][$key] = $val;
            };
        };
        return $new;
    };
    if (isset($_POST['mosaic-form'])) {
        $file_ary = reArrangeFiles($_FILES['image-user']);
        foreach ($file_ary as $file) {
            if (is_uploaded_file($file['tmp_name'])) {
                $valid_ext = array('jpg', 'jpeg', 'png');
                $valid_type = array('image/jpg', 'image/jpeg', 'image/png');
                $image_uploadedName = basename($file['name']);
                $name = strtolower(explode('.', $image_uploadedName)[0]);
                $ext = strtolower(explode('.', $image_uploadedName)[1]);
                if (in_array($ext, $valid_ext)) {
                    if (in_array($file['type'], $valid_type)) {
                        if (in_array('image/jpg', $valid_type) || in_array('image/jpeg', $valid_type)) {
                            $image = imagecreatefromjpeg($file['tmp_name']);
                        }
                        else if (in_array('image/png', $valid_type)) {

                        if (in_array('image/jpg', $valid_type) || in_array('image/jpeg', $valid_type)) {

                            $name_image = $name.'.'.$ext;
                            $image_user = $sql_connection->prepare('INSERT INTO images (name, users_id) VALUES (:name, :users_id)');

    <?  };
    } else {

    }
?>

上传并存储多重文件，然后插入html
