wp_handle_uploadを使って画像をアップロードする方法

こんにちは私は誰かが私がループでwp_handle_uploadを使用して複数の画像をアップロードすることができる方法を私に言うことができます

                   for($i=1;$i<count($_FILES['myfile']['name']);$i++){

                        $uploadedfile = $_FILES['myfile'].$i;

                        $upload_overrides = array( 'test_form'.$i => false );

                        $movefile = wp_handle_upload( $uploadedfile, $upload_overrides );

                        if ( $movefile && !isset( $movefile['error'] ) ) {
                          //  echo "File is valid, and was successfully uploaded.\n";

                            $dir_path= $movefile['url'];


                        } else {

                            echo $movefile['error'];
                        }
                    }//end loop

これが複数の画像をアップロードする方法の私の例です：

add_action( 'add_meta_boxes',   'my_test_metabox' );

function my_test_metabox() {
    add_meta_box( 'my_test_metabox', 'File upload', 'my_test_metabox_out', 'post' );
}

add_action('post_edit_form_tag', 'update_edit_form' );
function update_edit_form() {
    echo ' enctype="multipart/form-data"';
}

function my_test_metabox_out( $post ) {

    $files = get_post_meta( $post->ID, 'my_files', true );
    if( ! empty( $files ) ) {
        echo 'Files uploaded:' . "\r\n";
        foreach( $files as $file ) {
            echo '<img src="' . $file['url'] . '" width="100" height="100" />';
        }
        echo "\r\n";
    }
    echo 'Upload files:' . "\r\n";
    echo '<input type="file" name="my_files[]" multiple />';

}

add_action( 'save_post', 'my_files_save' );

function my_files_save( $post_id ) {

    if( ! isset( $_FILES ) || empty( $_FILES ) || ! isset( $_FILES['my_files'] ) )
        return;

    if ( ! function_exists( 'wp_handle_upload' ) ) {
        require_once( ABSPATH . 'wp-admin/includes/file.php' );
    }
    $upload_overrides = array( 'test_form' => false );

    $files = $_FILES['my_files'];
    foreach ($files['name'] as $key => $value) {
      if ($files['name'][$key]) {
        $uploadedfile = array(
            'name'     => $files['name'][$key],
            'type'     => $files['type'][$key],
            'tmp_name' => $files['tmp_name'][$key],
            'error'    => $files['error'][$key],
            'size'     => $files['size'][$key]
        );
        $movefile = wp_handle_upload( $uploadedfile, $upload_overrides );

        if ( $movefile && !isset( $movefile['error'] ) ) {
            $ufiles = get_post_meta( $post_id, 'my_files', true );
            if( empty( $ufiles ) ) $ufiles = array();
            $ufiles[] = $movefile;
            update_post_meta( $post_id, 'my_files', $ufiles );

        }
      }
    }

}

こんにちはここで私は私のプラグインで私が使い果たしたコードです、あなたがそれを理解してくれることを願っていて、どんな問題でもあなたが私に尋ねることができるなら： - 

if(isset($_FILES))
    {
        for ($i=1; $i < count($_FILES) ; $i++) 
        { 

            $uploadedfile = $_FILES['question_'.$i];
            ?>
            <script type="text/javascript">
            $(document).ready(function(){
                var nam = <?php echo "question".$i; ?>
                var namm = $("."+nam).prev().attr('name');

            });
            </script>
            <?php


        $upload_overrides = array( 'test_form' => false );

        $movefile = wp_handle_upload( $uploadedfile, $upload_overrides );

        if ( $movefile && !isset( $movefile['error'] ) ) {
            //echo "File is valid, and was successfully uploaded.\n";
            $filename = $movefile['file'];
        } else {
            /**
             * Error generated by _wp_handle_upload()
             * @see _wp_handle_upload() in wp-admin/includes/file.php
             */
            echo $movefile['error'];
        }

        // $filename should be the path to a file in the upload directory.
        //$filename = '/path/to/uploads/2013/03/filename.jpg';


        // Get the path to the upload directory.
        $wp_upload_dir = wp_upload_dir();

        $url = $wp_upload_dir['url'] . '/' . basename( $filename );
        echo $url."<br>";

    }           
    }

これが私のHTMLコードです： - 

    $question =get_post_meta($trivia->ID,'question',true);

     $c = 0;
     $id = uniqid();
    if ( count( $question ) > 0 ) {
        if(is_array($question)){

        foreach( $question as $questions ) {
            if ( isset( $questions['question'] ) ) {


                printf('<p>Question: <input type="text" name="question[%1$s][question]" value="%2$s"> -- <span class="remove_question">%3$s</span><span class="add_answer">   Add Answer</span></p>',   $c,$questions['question'],__('Remove Question'));
                for($i = 1; $i<=count($questions['answers']); $i++)
                {
                    if($questions['answers'][$i]['image'])
                    {
                        printf('<p>Option %5$s <input type="text" value="%1$s" name="question[%4$s][answers][%5$s][answer]"> Status <input type="text" value="%2$s" name="question[%4$s][answers][%5$s][status]"> Image <input type="text" name="question[%4$s][answers][%5$s][image]" value="%6$s"><img src="%6$s" height="100" widht="100"> -- <span class="remove_answer">%3$s</span></p>', $questions['answers'][$i]['answer'] ,$questions['answers'][$i]['status'], __('Remove Answer'), $c, $i,$questions['answers'][$i]['image']);
                    }
                    else
                    {
                        printf('<p>Option %5$s <input type="text" value="%1$s" name="question[%4$s][answers][%5$s][answer]"> Status <input type="text" value="%2$s" name="question[%4$s][answers][%5$s][status]"> -- <span class="remove_answer">%3$s</span></p>', $questions['answers'][$i]['answer'] ,$questions['answers'][$i]['status'], __('Remove Answer'), $c, $i);
                    }
