Question

我知道这可能非常简单，我在这里忽略了一些东西。

我在我们网站的前端有一个表单，用户可以通过表单上传图像，并在我们的商店中创建产品。我们正在使用Wordpress和Woocommerce，但我觉得这个问题很普遍，可以在这里询问。

目前上传一张图片时一切正常，当用户上传多张图片时，我该如何使用？

在我改变的形式中 <input type="file" name="thumbnail" id="thumbnail" /> 至 <input type="file" name="thumbnail" id="thumbnail" multiple />我认为将下面的内容包含在这样的内容中会起作用：

if ($_FILES) {
  foreach ($_FILES as $file => $array) {
    // do necessary code
  }
}

但事实并非如此。

这就是我创造帖子的内容。我不确定为什么将它包装在foreach $ FILES中不起作用？

$current_user = wp_get_current_user();

if(isset($_POST['submitted']) && isset($_POST['post_nonce_field']) && wp_verify_nonce($_POST['post_nonce_field'], 'post_nonce')) {


        $postTitle = trim($_POST['postTitle']);


    if($post_id)
    {
        wp_redirect(home_url());
        exit;
    }

    //random sku
$skuu = rand();

$new_post = array(
'post_title' => $skuu,
'post_content' => '', //add anything here like link to vendor or whatever
'post_status' => 'publish',
'post_type' => 'product'
);


//insert and update post
$post_id = wp_insert_post($new_post);
update_post_meta($post_id, '_sku', $skuu );

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

//find available attributes
$avail_attributes = Array(
    'high-resolution',
    'medium-resolution',
    'low-resolution'
);

//set terms (variations and attributes)
wp_set_object_terms ($post_id, 'variable', 'product_type');
wp_set_object_terms( $post_id, $avail_attributes, 'pa_resolution' );


//Categories
wp_set_object_terms( $post_id, array(esc_attr(strip_tags($_POST['postCat'])), esc_attr(strip_tags($_POST['raceCat']))), 'product_cat' );

    // Insert the post into the database
    wp_insert_post( $my_post );

简而言之，我只需要一种方法让上面的代码为每个上传的文件创建帖子，而不是像目前那样只上传一个文件。我所有人都没有想法

知道了，所以我将文件输入的名称从缩略图更改为缩略图[]。然后我将上面的粘贴包装在一个函数中，并将此部分添加到文件的顶部，它完美地运行：

if ( $_FILES ) {
    $files = $_FILES['thumbnail'];
        foreach ($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("" => $file);

              foreach ($_FILES as $file => $array) {
                      //call my function
                  create_var_product($file, $post_id);
              }
          }
    }
}

Foreach $ FILES创建帖子如何
