INSERT QUERY multiple_query到mysql数据库

Question

我的代码出了问题，其中已上传的图片只有表格中的一张，其中我选择了5张图片。

这是我的file-upload-employer.php

//Screen.java
package game.graphics;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;
import java.util.ArrayList;
import javax.swing.JPanel;
import entities.BodyParts;

public class Screen extends JPanel implements Runnable{ 
    public static final int WIDTH = 800, HEIGHT = 800;
    private Thread thread;
    private boolean running = false;    
    private BodyParts b;
    private ArrayList<BodyParts> snake; 
    private int ticks;  
    private int X = 10, Y = 10, size = 5;
    private boolean right = false, left = true, up=false, down = false;

    public Screen()
    {
        setPreferredSize(new Dimension(WIDTH, HEIGHT));     
        snake = new ArrayList<BodyParts>();
        Start();
    }

    public void Start()
    {
        running = true;
        thread = new Thread(this, "game loop");
        thread.start();
    }

    public void tick()
    {
        if(snake.size() == 0)
        {
            b = new BodyParts(X, Y, 10);
            snake.add(b);
        }
        ticks++;

        if(ticks > 2500)
        {
            //check the direction of movement
            if(right) {X++;}
            if(left) {X--;}
            if(up) {Y++;}
            if(down) {Y--;}

            ticks = 0;

            b = new BodyParts(X, Y, 10);
            snake.add(b);

            if(snake.size() > size)
            {
                snake.remove(0);
            }
        }
    }

    public void paint(Graphics g)
    {
        //g.clearRect(0, 0, WIDTH, HEIGHT);
        g.setColor(Color.BLACK);

        for(int i = 0;i<WIDTH/10 ;i++)
        {
            g.drawLine(i*10, 0, i*10, HEIGHT);
        }

        for(int i = 0;i<HEIGHT/10 ;i++)
        {
            g.drawLine( 0, i*10, WIDTH, i*10);
        }

        for(int i = 0; i < snake.size() ;i++)
        {
            snake.get(i).draw(g);
        }
    }

    public void Stop()
    {

    }

    @Override
    public void run() {
        // TODO Auto-generated method stub
        while(running)
        {
            tick();
            repaint();
        }
    }
}
// BodyParts.java
package entities;
import java.awt.Color;
import java.awt.Graphics;
public class BodyParts {    
    private int X, Y, width, height;
    public BodyParts(int X, int Y, int tile)
    {
        this.X = X;
        this.Y = Y;
        width = tile;
        height = tile;
    }   
    public void tick()
    {

    }   
    public void draw(Graphics g)
    {
        g.setColor(Color.black);
        g.fillRect(X*width, Y*height, width, height);

        g.setColor(Color.GREEN);
        g.fillRect(X*width + 2, Y*height + 2, width-4, height-4);

    }
}

这里是我放下相册名称并选择图片的表格。

<?php 
    include('admin/db/database_configuration.php');
    $sql = "SELECT * FROM tblalbums ORDER BY album_id DESC LIMIT 1";
    $result = $conn->query($sql);

    if ($result->num_rows > 0) {
        // output data of each row
       $row = $result->fetch_assoc();
       $wow = $row['album_id'];
       echo ($row['album_id']);
    } else {
    echo "0 results";
}
$conn->close();
?>
<?php
include('admin/db/database_configuration.php');
if (isset($_FILES["userfile"]) && !empty($_FILES["userfile"])) {
    $image = $_FILES['userfile']['tmp_name'];

    $imageSize = $_FILES['userfile']['size'];
    $imageType = $_FILES['userfile']['type'];
    $imageName = $_FILES['userfile']['name'];

    if (empty($_POST['aname'])){$albumname = 'NULL'; } else{ $albumname ="'". mysqli_real_escape_string($conn, $_POST['aname']) . "'";}

    $len = count($image);
    $path = "admin/images/";
    for ($i = 0; $i < $len; $i++) {
         if (isset($imageName[$i]) && $imageName[$i] !== NULL) {
             if(move_uploaded_file($image[$i], $path.$imageName[$i])) {
                $sql = "INSERT INTO `tblalum_photos` (imageName, imageSize, imageType, album_id) VALUES ('$imageName[$i]','$imageSize[$i]', '$imageType[$i]',$wow+1);";
                $sql .= "INSERT INTO `tblalbums` (albumName) VALUES ($albumname)";


                 if ($conn->multi_query($sql) === TRUE) {
                    echo '<script>alert("Images Sent")</script>';
                    echo '<script>window.location = "contact_us.php"</script>';
                } else {
                    echo "Error: " . $sql . "<br>" . $conn->error;
                }
            }
         }
    }
}
$conn->close();
?>

如果我不包含其他sql <form method="post" enctype="multipart/form-data" autocomplete="off"> <input type="text" class="desc" name="aname" placeholder="Album Name" style="width: 250px;" /> <?php include'admin/upload-preview.php' ?> <br><br> Select photo to send <div class="col-sm-12" id="result"> </div> <input id="files" type="file" name="userfile[]" multiple/><br> <button class="btn btn-danger" type="button" id="clear">CLEAR</button> <button id="yes" type="submit" name="save" formaction="file-upload-employer.php" class="btn btn-success">UPLOAD</button> </form> ，则会正确上传，但我必须将相册名称与照片一起提供。

感谢您将来的答案。
