Question

我使用wp_insert_post在woocommerces网站的前端添加产品

我当前的代码将上传所有图片，但只有最后一张图片会出现在产品图库图片

中

继承我的代码;

的functions.php

function my_handle_attachment( $file_handler, $post_id, $set_thu=false) {
  // check to make sure its a successful upload

  if ($_FILES[$file_handler]['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');

  $attach_id = media_handle_upload( $file_handler, $post_id );


  if ( is_numeric( $attach_id ) ) {

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

  }
  return $attach_id;  
}

前端

if ( $_FILES ) {
    $files = $_FILES['upload_attachment'];
    foreach ($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("upload_attachment" => $file);
            foreach ($_FILES as $file => $array) {
                $newupload = my_handle_attachment($file,$post_id);
            }
        }
    }
}


<input type="file" name="upload_attachment[]" multiple="multiple"  />

我在这里做错了什么？

Answer 1

您可以尝试在代码中更改此内容并尝试一次，我会在处理wordpress项目时记住这一点。

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

Answer 2

请试试这个

function my_handle_attachment($file_handler, $post_id)
{
  if ($_FILES[$file_handler]['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');

 $attach_id = media_handle_upload( $file_handler, $post_id );
 if (is_numeric($attach_id )) 
 {
 update_post_meta( $post_id, '_product_image_gallery', $attach_id );
 array_push($post_id, '_product_image_gallery', $attach_id)
 }
 return $attach_id;  
}
