首先如何匯入plupload

<script type="text/javascript" src="public/static/plupload/plupload.full.min.js"></script>

其中url引數：upload.php如下所示：

<?php

$typeArr = array("jpg", "png", "gif", "jpeg"); //允許上傳檔案格式
$path = "public/images/upload/post/"; //上傳路徑

if (isset($_POST)) {
    $name = $_FILES['file']['name'];
    $size = $_FILES['file']['size'];
    $name_tmp = $_FILES['file']['tmp_name'];
    if (empty($name)) {
        echo json_encode(array("error" => "您還未選擇圖片"));
        exit;
    }
    $type = strtolower(substr(strrchr($name, '.'), 1)); //獲取檔案型別

    if (!in_array($type, $typeArr)) {
        echo json_encode(array("error" => "請上傳jpg,png或gif型別的圖片！"));
        exit;
    }
    if ($size > (50000 * 1024)) { //上傳大小
        echo json_encode(array("error" => "圖片大小已超過50000KB！"));
        exit;
    }

    $pic_name = time() . rand(10000, 99999) . "." . $type; //圖片名稱
    $pic_url  = $path . $pic_name; //上傳後圖片路徑+名稱
    if (move_uploaded_file($name_tmp, $pic_url)) { //臨時檔案轉移到目標資料夾
        echo json_encode(array("error" => "0", "pic" => $pic_url, "name" => $pic_name));
    } else {
        echo json_encode(array("error" => "上傳有誤，清檢查伺服器配置！"));
    }
}
?>
 

建立多個plupload

$("#v_m").click(function(){
        myselect=document.getElementById("v_m");
        index=myselect.selectedIndex ;
        option = myselect.options[index].text;
        upload_total = option;
        var html = "";
        for( var i = 0; i < option; i++ )
        {
            var j = i+1;
            html += "<tr >";
            html += "<th style="+'width:150px;height:40px;font-size:16px;padding-left:10px;padding-right: 0px;'+">選項"+j+":"+"</th>";
            html += "<td><a id="+'btn'+j+"><img style="+'width:100px;height:100px;'+"  id="+'bbtn'+j+" src="+'public/images/local_upload.png'+"></a>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</td>";
            html +=     "<td><input name="+'neirong'+" type="+'text'+" style="+'width:350px;height:30px;font-size:16px'+" id="+'neirong'+"></td>";
            html += "</tr>";
        }
        $("#nnnn").html(html);
        var ids = new Array("btn1","btn2","btn3","btn4","btn5","btn6","btn7","btn8","btn9","btn10");
        $.each(ids,function(i,n){
            var self = this.toString();
            //例項化一個plupload上傳物件
            var uploader = new plupload.Uploader({
                browse_button : self, //觸發檔案選擇對話方塊的按鈕，為那個元素id
                url : "upload.php",//伺服器端的上傳頁面地址
                max_file_size: '2mb',//限制為2MB
                filters: [{title: "Image files",extensions: "jpg,gif,png"}]//圖片限制
            });
            //在例項物件上呼叫init()方法進行初始化
            uploader.init();
            //繫結各種事件，並在事件監聽函式中做你想做的事
            uploader.bind('FilesAdded',function(uploader,files){
                uploader.start();
            });
            uploader.bind('FileUploaded',function(uploader,file,info){
                var data = eval("(" + info.response + ")");//解析返回的json資料
                $("#b"+self).attr('src',data.pic);
            });
        });
 

建立一個表格裡面可以持續新增圖片

下面是樣式：

    <div class="send-action">
        <span>
            <a id="btn" href="javascript:;"><i class="file image outline large icon"></i>新增圖片</a>
        </span>

        <div class="release">
            <button class="ui teal button" onClick="saysub()">釋出 </button>
        </div>
    </div>
</div>

<div class="photo_upload_box_outside" id="photo_upload_box_outside" tabindex="2000">
    <div class="photo_upload_box">
        <a class="photo_upload_close" href="javascript:void(0);"onclick="photo_upload_close()"></a>
        <h1>本地上傳</h1>
        <p class="upload_num">共<span id="uploaded_length">0</span>張，還能上傳<span id="upload_other">9</span>張</p>
        <ul id="ul_pics" class="ul_pics clearfix">
            <li id="local_upload"><img src="public/images/local_upload.png" id="btn2"/></li>
        </ul>
        <div class="arrow_layer">
            <span class="arrow_top_area"><i class="arrow_top_bg"></i><em class="arrow_top"></em></span>
        </div>
    </div>
</div>
 

下面是plupload例項化：

var upload_total = 9;//最多上傳數量
    var uploader = new plupload.Uploader({//建立例項的構造方法
        runtimes: 'gears,html5,html4,silverlight,flash', //上傳外掛初始化選用那種方式的優先順序順序
        browse_button: ['btn', 'btn2'], // 上傳按鈕
        url: "upload.php", //遠端上傳地址
        flash_swf_url: 'public/static/plupload/Moxie.swf', //flash檔案地址
        silverlight_xap_url: 'public/static/plupload/Moxie.xap', //silverlight檔案地址
        filters: {
            max_file_size: '5mb', //最大上傳檔案大小（格式100b, 10kb, 10mb, 1gb）
            mime_types: [//允許檔案上傳型別
                {title: "files", extensions: "jpg,png,gif,jpeg"}
            ]
        },
        multi_selection: true, //true:ctrl多檔案上傳, false 單檔案上傳
        init: {
            FilesAdded: function(up, files) { //檔案上傳前
                var length_has_upload = $("#ul_pics").children("li").length;
                if (files.length >= upload_total) { //超過上傳總數量則隱藏
                    $("#local_upload").hide();
                }
                var li = '';
                plupload.each(files, function(file) { //遍歷檔案
                    if (length_has_upload <= upload_total) {
                        li += "<li class='li_upload' id='" + file['id'] + "'><div class='progress'><span class='bar'></span><span class='percent'>0%</span></div></li>";
                    }
                    length_has_upload++;
                });
                $("#ul_pics").prepend(li);
                uploader.start();
            },
            UploadProgress: function(up, file) { //上傳中，顯示進度條
                var percent = file.percent;
                $("#" + file.id).find('.bar').css({"width": percent + "%"});
                $("#" + file.id).find(".percent").text(percent + "%");
            },
            FileUploaded: function(up, file, info) { //檔案上傳成功的時候觸發
                showPhotoUploadBox($('#btn'));
                var uploaded_length = $(".img_common").length;
                if (uploaded_length <= upload_total) {
                    var data = eval("(" + info.response + ")");//解析返回的json資料
                    $("#" + file.id).html("<input type='hidden'name='pic[]' value='" + data.pic + "'/><input type='hidden'name='pic_name[]' value='" + data.name + "'/>\n\

                }
                showUploadBtn();
				$(".photo_upload_close").hide();
            },
            Error: function(up, err) { //上傳出錯的時候觸發
                alert(err.message);
            }
        }
    });
    uploader.init();

    function delPic(pic, file_id) { //刪除圖片 引數1圖片路徑  引數2 隨機數
        $.post("deletePic.php", {pic: pic}, function(data) {
            $("#" + file_id).remove();
            showUploadBtn();
        })
    }
    function showUploadBtn() { //是否顯示上傳按鈕
        var uploaded_length = $(".img_common").length;
        $("#uploaded_length").text(uploaded_length);
        var other_length = (upload_total - uploaded_length) > 0 ? upload_total - uploaded_length : 0;
        $("#upload_other").text(other_length);
        var uploaded_length = $(".img_common").length;
        if (uploaded_length >= upload_total) {
            $("#local_upload").hide();
        } else {
            $("#local_upload").show();
        }

    }
    function showPhotoUploadBox(obj) { //顯示上傳彈出層
        var left = obj.offset().left;
