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

Answer 1

extract($_POST);
$error=array();
$extension=array(“jpeg”,”jpg”,”png”,”gif”);
foreach($_FILES[“files”][“tmp_name”] as $key=>$tmp_name) {
$file_name=$_FILES[“files”][“name”][$key];
$file_tmp=$_FILES[“files”][“tmp_name”][$key];
$ext=pathinfo($file_name,PATHINFO_EXTENSION);

    if(in_array($ext,$extension)) {
        if(!file_exists("photo_gallery/".$txtGalleryName."/".$file_name)) {
            move_uploaded_file($file_tmp=$_FILES["files"]["tmp_name"][$key],"photo_gallery/".$txtGalleryName."/".$file_name);
        }
        else {
            $filename=basename($file_name,$ext);
            $newFileName=$filename.time().".".$ext;
            move_uploaded_file($file_tmp=$_FILES["files"]["tmp_name"][$key],"photo_gallery/".$txtGalleryName."/".$newFileName);
        }
    }
    else {
        array_push($error,"$file_name, ");
    }
}

并且您必须检查您的HTML代码

<form action="create_photo_gallery.php" method="post" enctype="multipart/form-data">
    <table width="100%">
        <tr>
            <td>Select Photo (one or multiple):</td>
            <td><input type="file" name="files[]" multiple/></td>
        </tr>
        <tr>
            <td colspan="2" align="center">Note: Supported image format: .jpeg, .jpg, .png, .gif</td>
        </tr>
        <tr>
            <td colspan="2" align="center"><input type="submit" value="Create Gallery" id="selectedButton"/></td>
        </tr>
    </table>
</form>
