Question

我尝试使用php管理员创建一个库可以上传多个图像所有图像都正确上传，就像图像在数据库中保存尽可能多，但问题是图像在文件夹中保存一次

与循环运行类似，图像名称在数据库中保存两次

Forexampl img1.jpg img2.jpg img3.jpg

这是数据库中的内容，但是当我打开我看到的文件夹时 img1.jpg其余的都没有来

这是我的代码

        $imggall = $_FILES["gallery_img"]["name"];
        $imgtype = $_FILES["gallery_img"]["type"];
        $imgtemp = $_FILES["gallery_img"]["tmp_name"];
        foreach($imggall as $key => $imgname) {
            $path = "./img/gallery/".$imgname;
            foreach($imgtemp as $key1 => $imgtemp1) {
                move_uploaded_file($imgtemp1, $path);
            }
            $confirm = mysqli_query($connect, "INSERT INTO gallery (image) VALUES ('$imgname')");
        }

以下是post.php页面的HTML表单

<p>
            <form method="POST" action="post.php?id=<?php echo $_SESSION["id"]; ?>" enctype="multipart/form-data">

            <div class="form-group">

                        $query = mysqli_query($connection, "SELECT DISTINCT cat_name FROM category");
                        while($row = mysqli_fetch_assoc($query)) {
                            if(!empty($row["cat_name"])) {
                    ?>

                    <label><input type="checkbox" name='catname' value="<?php echo $row["cat_name"]; ?>"><?php echo $row["cat_name"]; ?></label>

                        while($row1 = mysqli_fetch_assoc($query1)) {
                            if($row1["parent"] !== "None") {
                    ?>

                    <label><input type="checkbox" name='catname' value="<?php echo $row1["parent"]; ?>"><?php echo $row1["parent"]; ?></label>

循环两次可能会影响性能，此代码适用于我的图库

<?php 
    $files = $_FILES['gallery_img']['name'];
    $fileCount = count($files);
    for($i=0; $i<$fileCount; $i++) {
       $tmpFilePath = $files[$i];
       if ($tmpFilePath != ""){
           $newFilePath = "./img/gallery/" . $files[$i];
          if(move_uploaded_file($tmpFilePath, $newFilePath)) {
            // if files are uploaded then only insert into database
             $confirm = mysqli_query($connect, "INSERT INTO gallery (image) VALUES ('$files[$i]')");
          }
      }
    }
   ?>

希望这可能有效
