【问题描述】：

我将输入表单插入到两个不同的表中。第一个表是信息，另一个表是信息的图像。

当我提交信息时，我想在单独的表格中的第一张表格的每一行上传多张图片，并将每个图片的last_insert_id插入到第二张表格中。

table1
location ID | address | contact information 

table2
pictureID | location ID | filepath

使用以下代码，它只插入一张图片，但它会将所有图片上传到文件夹中。

<?php 

    include_once 'dbconnect.php';
    mysql_query("SET NAMES UTF8");
    session_start();
    $tbl_name="location";
    $tbl_image="image";

    if(isset($_POST['btn-upload'])){

        $name2=$_POST['name2'];
        $phone=$_POST['phone'];
        $email=$_POST['email'];
        $type=$_POST['type'];
        $other=$_POST['other'];
        $description=$_POST['description'];
        $address=$_POST['address'];
        $name=$_POST['name'];
        $lat=$_POST['lat'];
        $lng=$_POST['lng'];
        $country=$_POST['country'];
        $administrative_area_level_1=$_POST['administrative_area_level_1'];
        $place_id=$_POST['place_id'];
        $url=$_POST['url'];
        $website=$_POST['website'];




    $sql="INSERT INTO $tbl_name(name2, phone, email, type, other, description, address, name, lat, lng, country, administrative_area_level_1, place_id, url, website) VALUES ('$name2', '$phone', '$email', '$type','$other', '$description', '$address', '$name', '$lat', '$lng', '$country', '$administrative_area_level_1', '$place_id', '$url', '$website')";
    $result=mysql_query($sql);

        for($i=0; $i<count($_FILES['image']['tmp_name']); $i++)
        {
            $file = rand(1000,100000)."-".$_FILES['image']['name'][$i];
            $file_loc = $_FILES['image']['tmp_name'][$i];
            $file_size = $_FILES['image']['size'][$i];
            $file_type = $_FILES['image']['type'][$i];
            $folder="uploads/";

            // new file size in KB
            $new_size = $file_size/1024;  
            // new file size in KB

            // make file name in lower case
            $new_file_name = strtolower($file);
            // make file name in lower case

            $final_file=str_replace(' ','-',$new_file_name);
            $res=mysql_query("SELECT * FROM users WHERE userId=".$_SESSION['user']);
            $userRow=mysql_fetch_array($res);
            $userID=$userRow['userID'];

            if(move_uploaded_file($file_loc,$folder.$final_file))
            {
                $sql="INSERT INTO $tbl_image(user_ID, Location_ID, file) VALUES('$userID', LAST_INSERT_ID(), '$final_file')";
                mysql_query($sql);
                ?>
                <script>
                alert('successfully uploaded');
                window.location.href='index.php?success';
                </script>
                <?php
            }
            else
            {
                ?>
                <script>
                alert('error while uploading file');
                window.location.href='index.php?fail';
                </script>
                <?php
            }

        }

        if($result){
        echo "Successful";
        echo "<BR>";
        echo "<a href='index.php'>Back to main page</a>";
        }

        else {
        echo "ERROR";
        }

        if($result1){
        echo "Upload Successful";
        echo "<BR>";
        echo "<a href='locationform.php'>Back to main page</a>";
        }

        else {
        echo "ERROR";
        }


    }   




?> 

<?php 
// close connection 
mysql_close();
?>

【问题讨论】：

您的代码是正确的，但是在第一次成功插入图像表后，您正在重定向代码。所以你只能在图像表中插入一个。
由于 mysql_* 在 PHP 5.5 中已被弃用（请参阅 PHP doc），您应该真的考虑使用 PPS : Prepared Parameterized Statements。这将有助于Preventing SQL injection。从不相信用户的数据！请在页面顶部使用error_reporting(E_ALL); ini_set('display_errors', 1);，如果出现任何错误，请告知我们
此外，您不应该假设您的 sql 调用是成功的。在每个 sql 查询之后添加错误处理并打印出任何错误消息
那我怎么不重定向代码呢？

【解决方案1】：

$b=$pdo->prepare(" INSERT INTO `table1` SET `address`=:address, `contact`=:contact ");
$b->bindParam(":address",$address);
$b->bindParam(":contact",$contact);
$b->execute();
$LastId = $pdo->lastInsertId();

if($LastId > 0){
    $b=$pdo->prepare(" INSERT INTO `table2` SET `pictureID`=:pictureID, `filepath`=:filepath ");
    $b->bindParam(":pictureID",$LastId);
    $b->bindParam(":filepath",$filepath);
    $b->execute();
}

终于想通了。有问题的是 last_insert_ID。 Last_instert_ID 必须在 For 循环之外声明。

$locationID=mysql_insert_id($conn);

Above 被添加到第一个插入查询的正下方。

$sql="INSERT INTO $tbl_location(name2, phone, email, type, other, description, address, name, lat, lng, country, administrative_area_level_1, place_id, url, website) 
    VALUES ('$name2', '$phone', '$email', '$type','$other', '$description', '$address', '$name', '$lat', '$lng', '$country', '$administrative_area_level_1', '$place_id', '$url', '$website')";
    $result=mysql_query($sql);

    $locationID=mysql_insert_id($conn);

    for($i=0; $i<count($_FILES['image']['name']); $i++)
    {
        $file = rand(1000,100000)."-".$_FILES['image']['name'][$i];
        $file_loc = $_FILES['image']['tmp_name'][$i];
        $file_size = $_FILES['image']['size'][$i];
        $file_type = $_FILES['image']['type'][$i];
        $folder="uploads/";

        // new file size in KB
        $new_size = $file_size/1024;  
        // new file size in KB

        // make file name in lower case
        $new_file_name = strtolower($file);
        // make file name in lower case

        $final_file=str_replace(' ','-',$new_file_name);
        $res=mysql_query("SELECT * FROM users WHERE userId=".$_SESSION['user']);
        $userRow=mysql_fetch_array($res);
        $userID=$userRow['userID'];


        if(move_uploaded_file($file_loc,$folder.$final_file))
        {
            $sql2="INSERT INTO $tbl_image(user_ID, Location_ID, file) VALUES('$userID', '$locationID', '$final_file')";
            $result = mysql_query($sql2);
            ?>
            <script>
            alert('successfully uploaded');
            window.location.href='index.php?success';
            </script>
            <?php
        }
        else
        {
            ?>
            <script>
            alert('error while uploading file');
            window.location.href='index.php?fail';
            </script>
            <?php
        }

    }
