我用前端做了一个Plupload。WordPress Plupload是非常定制的，因此我从头开始就将其作为插件实现。我将展示一个使用函数的示例。php

从下载Pluploadhttp://www.plupload.com/download/ 并将主题放入js/thirdparty/plupload/{all\\u files}中

用于函数的代码。php

    //Plupload File
    wp_enqueue_script( \'plupload\', get_template_directory_uri() . \'/js/thirdparty/plupload/js/plupload.full.min.js\', array( \'jquery\' ) );
    //Plupload Queue File (up to you using queue)
    wp_enqueue_script( \'plupload-queue\', get_template_directory_uri() .\'/js/thirdparty/plupload/js/jquery.plupload.queue.min.js\', array( \'jquery\' ) );
    //Your own JS (make sure you set the dependencies)
    wp_enqueue_script( \'my-functions\', get_template_directory_uri() .\'/js/functions.js\', array( \'jquery\' , \'plupload\', \'plupload-queue\' ) );

    //Send the wp-admin/wp-ajax.php to the Javascript:
    wp_localize_script( \'my-functions\', \'customObj\', array(
        \'ajax_url\' => admin_url( \'admin-ajax.php\' )
    ) );


    //AJAX Upload function
    add_action( \'wp_ajax_my_custom_plupload_ajax_method\', \'process_ajax_my_custom_plupload_ajax_method\' );
    add_action( \'wp_ajax_nopriv_my_custom_plupload_ajax_method\', \'process_ajax_my_custom_plupload_ajax_method\' );

    //Here you will code your upload depends on your needs:
    function process_ajax_my_custom_plupload_ajax_method() {
        $mimes = array(
            \'jpg\' =>\'image/jpg\',
            \'jpeg\' =>\'image/jpeg\',
            \'gif\' => \'image/gif\',
            \'png\' => \'image/png\'
        );


        $uploadedfile = $_FILES[\'file\']; //Default from Plupload.

        //You could use media_handle_upload also, up to you.
        $upload_overrides = array( \'test_form\' => false, \'mimes\' => $mimes );
        $movefile = wp_handle_upload( $uploadedfile, $upload_overrides );


        if ( is_wp_error( $movefile ) ) {
            return wp_send_json_error( $movefile );
        } else {
            return wp_send_json_success( $movefile );
        }
    }

而不是像通常那样使用JS

要在函数中使用的代码。js公司：

var uploader = new plupload.Uploader({
    runtimes : \'html5, flash, silverlight, html4\',
    url : customObj.ajax_url, //it comes with wp_localize_script
    drop_element: \'sortable\', //up to you
    chunk_size : \'1mb\',
    unique_names : true,

    resize : {width : 320, height : 240, quality : 90}, //Here you go to resize images

    browse_button : \'pickfiles\', // you can pass in id...
    container: \'container\', // ... or DOM Element itself

    filters : {
        max_file_size : \'2mb\',

        // Specify what files to browse for
        mime_types: [
            {title : "Image files", extensions : "jpeg,jpg,gif,png"}
        ],
        prevent_duplicates: true
    },

    multipart_params: {
        \'action\': \'my_custom_plupload_ajax_method\' //Depends on the PHP method
    },

    //Flash settings
    flash_swf_url : \'/plupload/js/Moxie.swf\',

    // Silverlight settings
    silverlight_xap_url : \'/plupload/js/Moxie.xap\',

    init: {
        PostInit: function() {
            document.getElementById(\'filelist\').innerHTML = \'\';

            document.getElementById(\'uploadfiles\').onclick = function() {
                uploader.start();
                return false;
            };
        },

        FilesAdded: function(up, files) {
            plupload.each(files, function(file) {
                document.getElementById(\'filelist\').innerHTML += \'<div id="\' + file.id + \'">\' + file.name + \' (\' + plupload.formatSize(file.size) + \') <b></b></div>\';
            });
        },

        UploadProgress: function(up, file) {
            document.getElementById(file.id).getElementsByTagName(\'b\')[0].innerHTML = \'<span>\' + file.percent + "%</span>";
        },

        Error: function(up, err) {
            document.getElementById(\'console\').innerHTML += "\\nError #" + err.code + ": " + err.message;
        },
        FileUploaded: function(up, file, info) {
            var photo = JSON.parse(info.response);
            console.log(photo); //Here you\'ll use in your JS. That\'s the WP result.
        }
});

uploader.init();

希望对你有用。
