Question

所以我传递了一个来自type =＆＃34;文件的文件数组＆＃34;输入，我想将它们发送到服务器上的文件夹。 move_uploaded_file（）不起作用。

我只是希望首先上传一个文件，并在之后为整个数组制作循环或其他内容。

我确实有enctype =＆＃34; multipart / form-data＆＃34;在HTML格式。路径正确，该文件夹为空。

试图在内部if之前设置$ image_paths [0] = $ images [0] [＆＃34; tmp_name＆＃34;]并且在第一个if内部返回＆＃34; / tmp / php2SytkN＆＃34; 。这是tmp_name的样子吗？还试图返回$ images [0] [＆＃39;尺寸＆＃39;]并且它是正确的，所以文件就在那里。

function upload_to_file($images){

$image_paths = array();
$target_dir = "uploads/images/";
$path = $target_dir . basename($images[0]["name"]);
if(isset($images[0]) && $images[0]['size'] > 0) {

    if (move_uploaded_file($images[0]["tmp_name"], $path)) {
        $image_paths[0] = $path;
    }
}
return $image_paths;

}

编辑：我尝试了但我不认为$ _FILES [0]会起作用，因为我已经在使用它了。我还需要第二个$ _FILES数组来存储视频，所以我想创建自己的数组。

她试图做的更详细：

if(isset($_POST['submit'])){//main form is submitted

    // upload each of the selected images into a directory on the server and return the array of paths for each one:
    $image_paths = upload_to_file($_SESSION['images']);
    //then insert those paths as varchar in a database table and return the id of the new table row:
    $images_fk = upload_to_db($image_paths);
    //finally insert the the id of the umages row into the main table along with all the other form stuff:
    $query = "INSERT INTO main_table (...other stuff from the main form..., images_fk) VALUES (...other stuff from the main form...'{$images_fk}')";
    $result = mysqli_query($db, $query);

}elseif(isset($_POST['submit_image'])){//image form is submitted

     if(count($_SESSION['images']) < 5){
          //store the file into a session array so a new image can be selected with the same input type=file:
          array_push($_SESSION['images'], $_FILES['image_file']);
     }

}

编辑：HTML部分：

//a form with one type=file input that submits to the top of the page:
<form id="form" action="home.php" method="post" enctype="multipart/form-data">
        <input type="hidden" name="MAX_FILE_SIZE" value="8000000">

        <input class="upload_btn" type="file" name="image_file" id="image_file">

  //some mix of php and html to show the names of uploaded items as you select them:
        <?php for ($i = 0; $i < count($_SESSION['images']); $i++) {
            if($_SESSION['images'][$i] != null){
                echo "<p>";
                echo htmlentities($_SESSION['images'][$i]['name']) . "&nbsp&nbsp";
                echo "<a href='image_remove.php?ind=" . urlencode($i) . "'>Remove</a></p>";
            }
        } ?>
        <input type="submit" id="img_submit" class="form_button" name="submit_image" value="upload"/>
    </form>

    //Then do the same form for videos....

move_uploaded_file（）在尝试上传图片时返回false
