Php 找不到文件并上载

我尝试将多个图像上传到系统，但上传后无法找到图像。 当我尝试var_dump上传的项目总数时，它始终显示0个上传的项目

这里需要帮助，谢谢

这是我的HTML代码：

<form id="login-form" action="" method="post" enctype="multipart/form-data" >
    <input type="file" name="file[]" multiple="multiple"  />
<input type="submit" name="submit-scam" value="Submit">
</form>

这是我的PHP代码：

<?php
//Check Error
error_reporting(E_ALL);
//Start Session
session_start();
//Include Database
include_once('dbConnect.php');


if (isset($_POST['submit-scam'])){
    echo "button clicked";

if(isset($_FILES['file'])){ 

            /*This Function is to loop multiple upload file into DB*/

    $total = count($_FILES['file']['name']);

    for ($i=0; $i<$total; $i++) {

    $file = rand(1000,100000)."-".$_FILES['file']['name'][$i];
    $file_loc = $_FILES['file']['tmp_name'][$i];
    $file_size = $_FILES['file']['size'][$i];
    $file_type = $_FILES['file']['type'][$i];
    $folder="uploads/";
    $today = date('Y-m-d');

    // 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);


    if(move_uploaded_file($file_loc,$folder.$final_file))
    {

                    //To Insert Latest base to SQL Latest submit ec_claim id 

                    $sql="INSERT INTO db_evidence(db_evidence_name,db_evidence_type,db_evidence_scam_id,db_evidence_users_id) 
                    VALUES('$final_file','$file_type','1','1')";
                    $result = mysqli_query($connection, $sql) or die(mysqli_error($connection));
                    echo "success upload";
                    // header("Location:index.php");
                }
                else
                {
                    echo "failed to upload";
                }
                }
            } else {
                echo "error no file is found";
            }
}
?>

添加到表单中

<form id="login-form" action="" method="post" enctype="multipart/form-data">
    <input type="file" name="file[]" multiple="multiple"  />
    <input type="submit" name="submit-scam" value="Submit">
</form>



这应该可以让您阅读
type=“file”
谢谢您的回复，我刚刚尝试添加了“enctype”，它仍然无法获得图像…没有显示错误消息，但我使用了我自己的isset过滤器，它显示“file”为空。现在如何工作！谢谢你的帮助！用
