wp_insert_post多路上传图片

Question

嗨，我想用wp_insert_post上传多个图像，但只有多个上传的最后一个图像插入其他图像上传，但不附加在那里.

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

          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;

}

Answer 1

请试试这个

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;

}

Answer 2

agp_process_wooimage每次运行时都会替换某个帖子id的元数据：

post id = 33 '_product_image_gallery‘的元数据中只有最后一个文件，因为之前的文件已经被替换了。

希望这能有所帮助;-)
