Show Copyright for images in Standard Editor Blog Posts

Hey Nikko,
basically i have the problem on several sites, all of which I run with your great theme.

In the Advanced Editor I can set when and how the copyright should be displayed. In the blog I use the standard editor and insert the images via “insert media”. At this point I have no choice regarding the display of the copyright information.

Enclosed you will find a link to an exemplary page. For the header image I found a short css code in the forums and the copyright shows beneath the picture. The picture is used again at the end of the article. Inserted via the standard editor. There we had to manually add the copyright in the caption, as there is no way to show it automatically …

As I said, my aim is to show the copyright information for all images that are used in the blog via the standard editor, provided that the copyright information has been saved in the media library with the image.

I found some snippets for functions.php on the web and the forums but none is working in the expected way.

Hoping for a solution!

Cheers, Daniel

Dear Nikko,

Thank you for your answer. Since the data is saved in the database, it should also be able use it in the standard editor. There are even instructions on the Internet for this, but they refer to a selfmade copyright field (see link) but the field is already given by your theme.

In the meantime I found a post from Ismael, unfortunately I don’t quite understand the explanation since it offers possibilities and not one single solution. It seems to be about exactly the issue that I am facing: https://kriesi.at/support/topic/copyright-images-2/#post-1228898

Therefore I believe there is an option for this and would be happy to receive a brief explanation or instructions. Thank you!

Hey Nikko,

thanks for the code. I made some adjustments and it kind of works, but it’s not really convenient. I invested several hours to automatically place the copyright line with the image in the text, depending on the alignment of the image in the text flow.

add_filter('get_image_tag', function($html, $id, $alt, $title, $align, $size) {
	$copyright_text = get_post_meta( $id, '_avia_attachment_copyright', true );
	if ($copyright_text) {
		$image = $html;
		$html = '<figure class="copyright-image-wrapper">' . $image;
		$html .= '<p class="my-copyright">' . $copyright_text . '</p>';
		$html .= '</figure>';
	}
	return $html;
}, 10, 6);

function copyright_textfluss(){
    ?>
    <script>
		jQuery(document).ready(function($) {
			$('.copyright-image-wrapper:has(.alignleft)').addClass('alignleft');
			$('.copyright-image-wrapper:has(.aligncenter)').addClass('aligncenter');
			$('.copyright-image-wrapper:has(.alignright)').addClass('alignright');
		});
	 </script>
    <?php
}
add_action('wp_head', 'copyright_textfluss'); 

But there are still two problems:

• All the html-markup stays in the blog entry if a picture is deleted. This is annoying and therefore not a really nice solution …
• The copyright-information is simply copied into the text, there is no connection to the database. If there are changes to the copyright-information in the media library it won’t reflect in the blog.

In the theme image-element it adds a snippet to the shortcode like [copyright=’icon-reveal’]. Couldn’t something like that also be implemented for the standard editor?

Hope you have a good idea!

Hi Nikko,

I will try to find a good solution. But since the copyright is implemented through Enfold I would have to know which selector I have to use to call the copyright field content from an image with added copyright information.

In your code I found:

_avia_attachment_copyright

Is this where the copyright information is saved?

Could I use something like that:

function get_image_copyright( $attachment_id = null ) {
	$attachment_id = attachment_url_to_postid( $image_url );
	if ( $attachment_id )
		return get_post_meta( $attachment_id, '_avia_attachment_copyright', true );
}

Does that trigger the wanted information? If yes I only need a hint where to place a function to show it for every image in the blog.

Something like:

echo get_image_copyright();

What do you think?

All the best,
Daniel

Hi Nikko,
Thanks for your reply. I found some links online that seemed to offer a solution for this problem. Isn’t the link in private about basically the same thing I want to achieve?
Best regards,
Daniel

For sure, Guenni, nor problem: https://bavotasan.com/2012/add-a-copyright-field-to-the-media-uploader-in-wordpress/. What do you think? Any suggestions?

That is true, Guenni. Thanks for your advice. I want to use the information from the copyright field in the standard WordPress text editor also, not only in avia layout architect. Therefore I need to load the copyright information from the field inserted by Enfold into a standard editor blog post. Basically that is working with Nikkos code (thanks!) but it is not dynamic (see post #1289982 above). Any ideas?

All the best, Daniel

No idea how to solve this? I think the information is in the database and could be loaded somehow.

If a user could place a shortcode like

[media_copyright]

on a page and this would display a list in the frontend like

Media name (linked to page where it is used): Copyright information
Media name (linked to page where it is used): Copyright information
Media name (linked to page where it is used): Copyright information

and if an image is used multiple times it has multiple entries in the list.

Something like this would be quite helpful for users in Europe …

Does anyone know whether it is possible to collect a list of all credits specified in the media library on one page via a shortcode or something similar?
