Question

我已尝试使用以下代码进行大尺寸视频上传。它一次只上传一个文件，但我想一次上传多个文件，我该怎么办？

<?php
$target_path = "C:/xampp/htdocs/uploadVideo/uploadedFile/";
$tmp_name = $_FILES['fileToUpload']['tmp_name'];
$size = $_FILES['fileToUpload']['size'];
$name = $_FILES['fileToUpload']['name'];
$name2 = $_GET['filename'];
$target_file = $target_path.$name;
$complete =$target_path.$name2;
$com = fopen($complete, "ab");
error_log($target_path);
    $in = fopen($tmp_name, "rb");
        if ( $in ) {
            while ( $buff = fread( $in, 1048576 ) ) {
                fwrite($com, $buff);
            }   
        }
        fclose($in);
    fclose($com);
?>

和javascript代码在这里：

<script type="text/javascript" > 
function uploadchange() {
            var input = document.getElementById("file");
            var ul = document.getElementById("uploadlist");
            while (ul.hasChildNodes()) {
                ul.removeChild(ul.firstChild);
            }
            for (var i = 0; i < input.files.length; i++) {
                var li = document.createElement("li");
                thefilesize = input.files[i].fileSize||input.files[i].size;
                if (thefilesize > 1024 * 1024){
                             thefilesize = (Math.round(thefilesize  * 100 / (1024 * 1024)) / 100).toString() + 'MB';
                         }else{
                                thefilesize = (Math.round(thefilesize  * 100 / 1024) / 100).toString() + 'KB';
                }

                li.innerHTML = input.files[i].name + " " + thefilesize ;
                ul.appendChild(li);             
            }
            if(!ul.hasChildNodes()) {
                var li = document.createElement("li");
                li.innerHTML = 'No Files Selected';
                ul.appendChild(li);
            }
            sendRequest();

        }

window.BlobBuilder = window.MozBlobBuilder || window.WebKitBlobBuilder || window.BlobBuilder;

            function sendRequest() {
        var blob = document.getElementById('file').files[0];
                var BYTES_PER_CHUNK = 1048576; // 1MB chunk sizes.
                var SIZE = blob.size;
                var start = 0;
                var end = BYTES_PER_CHUNK;
        window.uploadcounter=0;
        window.uploadfilearray = [];
        document.getElementById('progressNumber').innerHTML = "Upload: 0 % ";
                while( start < SIZE ) {

                    var chunk = blob.slice(start, end);
            window.uploadfilearray[window.uploadcounter]=chunk;
                        window.uploadcounter=window.uploadcounter+1;
                    start = end;

                if (file) {
                    var fileSize = 0;
                    if (file.size > 1024 * 1024)
                        fileSize = (Math.round(file.size * 100 / (1024 * 1024)) / 100).toString() + 'MB';
                    else

我应该一次为多个文件上传做什么？我想上传大尺寸文件和多个文件...这段代码一次只能用于一个文件..所以如何使用这个代码上传多个文件。我可以在这个代码申请循环多次上传吗？

Answer 1

开始更改

<input type="file"  id="file">

到

<input type="file" name="file[]" id="file" multiple />

在你的HTML中。

然后在php中为用户上传的每个文件创建一个循环。

这是我最近一次上传多个文件所做的;

if($_SERVER['REQUEST_METHOD'] == "POST") {

foreach ($_FILES['file']['name'] as $f => $name) {

    $allowedExts = array("pdf", "jpeg", "jpg", "png");
    $temp = explode(".", $name);
    $extension = end($temp);
    $naam = rand(1111111,9999999);
    if ($_FILES["file"]["size"][$f] < 200000000000 && in_array($extension, $allowedExts))
    {
        if ($_FILES["file"]["error"][$f] > 0)
        {
            echo "Error: " . $_FILES["file"]["error"][$f] . "<br>";
        }
        else
        {
            $filenaam = $naam . "." .$extension;
            move_uploaded_file($_FILES["file"]["tmp_name"][$f], "/your/path/goes/here/" . $filenaam);
            echo $filenaam . "<br />";
        }
    }
    else
    {
        echo "Wrong file.";
    }
}
}
