[英]WordPress: Upload images to ACF using repeater image field
My HTML form allows users to select any number of images to be uploaded to a custom post type. 我的HTML表单允许用户选择任意数量的图像以上传到自定义帖子类型。 I've created a repeater field in ACF called 'images', of 'image' objects.
我在ACF中创建了一个“图像”对象的转发器字段,称为“图像”。
How do I save the uploaded images into that repeater field? 如何将上传的图像保存到该转发器字段?
This is what I currently have: 这是我目前拥有的:
$files = $_FILES['file'];
$image_number = 1;
foreach ($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]
);
$uploaded_file = wp_handle_upload($file, array('test_form' => FALSE));
update_sub_field( array('images', $image_number++, 'image'), $uploaded_file, $post_id);
}
}
But the images aren't saved. 但是图像不会保存。 Any help appreciated, thanks!
任何帮助表示赞赏,谢谢!
As far as I see, your use of the update_field
function especially it's signature is wrong. 据我所知,您对
update_field
函数的使用尤其是其签名是错误的。 You mixed up the parameters. 您混合了参数。 Have a look here: Wordpress ACF: How to add rows to a repeater field attached to a user via custom code (PHP)

Try the following code. 请尝试以下代码。 It is working for me.
它为我工作。 Although it's an old post, it might help someone else in future.
尽管这是一个过时的帖子,但将来可能会对其他人有所帮助。
$attachment = array(
'guid' => $upload_dir . '/' . basename( $filename ),
'post_mime_type' => $filetype['type']
);
$attachment_id = wp_insert_attachment($attachment, $filename, $parent_post_id);
$row = array(
'name' => "Hello",
'logo' => $attachment_id, // this is where you put post id of your image
'website' => "http://hello.com"
);
add_row( "repeater_field", $row, $blog_post_id);
I also noticed that add_row works only if you have already at least one row. 我还注意到,只有当您已经至少有一行时,add_row才起作用。 But if you want to add a new row, use update_field.
但是,如果要添加新行,请使用update_field。 Take a look here: add_row in ACF Pro isn't saving repeater values
