woocommerce产品图库图片从前端上传

Question

我创建了一个代码，发布产品从前端问题是当我上传画廊图像从前端只有最后一次图像上传。

以下是代码

<form action="#" method="post" enctype="multipart/form-data">  <input type="file" name="agp_gallery[]" id="agp_image_files" style="width:90%; margin-left:5px;" multiple>

下面是函数multiupload

  agp_process_image('agp_image_file', $post_id, $result['caption'], $result['content'], $result['author']);
          if ( $_FILES ) {
$files = $_FILES['agp_gallery'];
foreach ($files['name'] as $key => $value) {
if ($files['name'][$key]) {
$file = array(
'name' => $files['name'][$key],
'type' => $files['type'][$key],
'tmp_name' => $files['tmp_name'][$key],
'error' => $files['error'][$key],
'size' => $files['size'][$key]
);

$_FILES = array("agp_gallery" => $file);

foreach ($_FILES as $file => $array) {

    agp_process_wooimage($file, $post_id, $result['caption']);
}
}
}
}

下面是main函数

function agp_process_wooimage($file, $post_id, $caption){

     if ($_FILES[$file]['error'] !== UPLOAD_ERR_OK) __return_false();


  require_once(ABSPATH . "wp-admin" . '/includes/image.php');
  require_once(ABSPATH . "wp-admin" . '/includes/file.php');
  require_once(ABSPATH . "wp-admin" . '/includes/media.php');

  $attachment_id = media_handle_upload($file, $post_id);

  update_post_meta($post_id, '_product_image_gallery', $attachment_id);

  $attachment_data = array(
    'ID' => $attachment_id,
    'post_excerpt' => $caption
  );

  wp_update_post($attachment_data);

  return $attachment_id;

}

这是最终的代码：

  // Get the upload attachment files
   if ( $_FILES ) {
$files = $_FILES['agp_gallery'];
foreach ($files['name'] as $key => $value) {
if ($files['name'][$key]) {
$file = array(
'name' => $files['name'][$key],
'type' => $files['type'][$key],
'tmp_name' => $files['tmp_name'][$key],
'error' => $files['error'][$key],
'size' => $files['size'][$key]
);

            $_FILES = array("agp_gallery" => $file);

            foreach ($_FILES as $file => $array)
            {
                $newupload = agp_process_wooimage($file,$post_id);
            }
        }

    }
 }

function agp_process_wooimage($file, $post_id){

     if ($_FILES[$file]['error'] !== UPLOAD_ERR_OK) __return_false();


  require_once(ABSPATH . "wp-admin" . '/includes/image.php');
  require_once(ABSPATH . "wp-admin" . '/includes/file.php');
  require_once(ABSPATH . "wp-admin" . '/includes/media.php');

  $attachment_id = media_handle_upload($file, $post_id);
 update_post_meta($post_id,  array_push($post_id, '_product_image_gallery', $attachment_id));

  return $attachment_id;

}
