一键输入多个图像上传PHP表单

Question

我已经尝试进行这项工作了一段时间了。但是我似乎无法使其正常工作。我想只使用一个输入就拥有多张图片上传表格。

这是我的upload.php

<?php

include("../include/session.php");

session_start();

$allowedExts = array("jpeg", "jpg", "png", "gif");

$extension = end(explode(".", $_FILES["upload"]["name"]));

if(isset($_FILES['upload']['tmp_name']))

{

    for($i=0; $i < count($_FILES['upload']['tmp_name']);$i++)

    {

        if (($_FILES["upload"]["name"] < 90000000000000000)

            && in_array($extension, $allowedExts)) {

                if ($_FILES["upload"]["error"] > 0)

                {

                    header('location: '.$error); die;

                }

                else

                {

                    if (file_exists("../icons/".$_SESSION["username"] ."/" . $_FILES["upload"]["name"]))

                    {

                    echo "error";

                    }

                    else

                    {

                        if(!is_dir("../icons/". $_SESSION["username"] ."/")) {

                            mkdir("../icons/". $_SESSION["username"] ."/");

                        }

                        $temp = explode(".",$_FILES["upload"]["name"]);

                        $file = rand(1,999999999999) . '.' .end($temp);

                        move_uploaded_file($_FILES["upload"]["tmp_name"], "../icons/". $_SESSION["username"] ."/". $file);  

                    }

                }

            }

        } else {

            echo "yep error";

        }

    }

} 

?>

如果我把线

if(isset($_FILES['upload']['tmp_name']))

{

    for($i=0; $i < count($_FILES['upload']['tmp_name']);$i++)

    {

使用相应的结束括号，它似乎可以正常工作。图像完美上传。但事实是，它只允许我上传一个。

请我真的需要您的专业知识。谢谢
