    Hi,

    I use rwmb_meta to get alle the values from a image upload field.
    I have max. 5 images in this field. Sometimes, I have to adress the images seperatly, fro example I want only output the third element of the array.

    I had expected that the array keys of the individual image elements would be numbered from 0 to 4 (because I have mx. 5 images in the field) so that i could address them directly: $image[1][url] for example gives me the url of the second image.

    But the in the first level of that array the key is the same number as the ID of the image.

    I'dont know the ID bevor output, so how can i adress single images of that array?

    Kind regards,
    Ole

    Hi Ole,

    The field image_upload saved the IDs of images in the database. So if you want to get an array with the indexed key like that, you can use the function get_post_meta(). For example:

    $value = get_post_meta( $post_id, 'image_upload' );

    It will return an array of image IDs and you can get image info by using the function wp_get_attachment_image().

    Hi Long,

    Thank you very much, I got it!

    By the way...when I click here in the forum of my name to see my last postings, on this page the pagination doesn't work. I doesn't matter wich page number I click, I get redirected to the first page.

    Kind regards,
    Ole
