Add custom field for HTML?

Thanks for your kind words regarding the plugin, for the research you’ve already done and for your detailed explanation of your goal.

I think the best solution for your application is, as you outlined in “2b. use a shortcode …“, a custom shortcode you can add to your posts. The shortcode would find the post’s Featured Image, access one or more custom fields containing the attribution values, add the HTML markup and return the results. It looks like most of the HTML is constant and there are one or more values that change from image to image; is that right?

I would modify your “1. Add some custom HTML when I upload an image …” to separate the HTML from the data values for the image. There are three ways to add the data values on upload:

1. Define one or more IPTC/EXIF or Custom Field mapping rules. Many photographers use a tool like Adobe Lightroom or Photoshop to add metadata like copyright information to their images. This can be copied into custom fields when they are uploaded.
2. Use the “Bulk Edit area” on the Media/Add New (Upload New Media) screen. You can add your custom fields here (and to the Bulk Edit area on the Media/Assistant screen) and then fill them in just before you drop the images into the upload area.
3. Use the Media/Edit screen or the Media/Assistant Quick Edit area to add the values after the upload completes.

You can also add the custom fields to the “ATTACHMENT DETAILS” area of the Media Manager Modal (popup) Window. MLA does not do this, but some other plugins such as Advanced Custom Fields support it.

That should give you an idea of what can be done for your application. Let me know if that makes sense, if a custom shortcode will work for you and what additional details you need to understand and implement your application. I will leave this topic unresolved for now. Thanks for your interest in the plugin.

Hi David, thanks for the pointers. I’ve used Advanced Custom Fields to add a field called “img_html” to the Media Manager modal popup window, to the Attachment Details section, and that now stores my HTML for the attribution for each image. I don’t want to parameterise it because sometimes the attribution text is different (Wikimedia Commons is different to Flickr etc).

Can you help me work out how to set up the shortcode to insert the contents of this field into a Post?

Thanks.

Thanks for your update with the additional application information.

You asked “Can you help me work out how to set up the shortcode to insert the contents of this field into a Post?” Just to confirm, I understand that to mean that you would like a shortcode that:

1. Finds the Featured Image for the post/page in which the shortcode is embedded
2. Finds the value of the img_html custom field assigned to the Featured Image item
3. Echoes the content of the custom field to the post/page

If that’s right, I will work up an example plugin for you. If you send me you contact information I can email you a copy of the plugin when it’s ready. You can use the Contact Us page at our web site:

Hi David, yes that’s exactly what I’d like. I’ve sent my details through your link.

Thanks again, your help is really appreciated!

Thanks for working with me offline to develop and test the custom plugin. I am happy to know it is working for you.

For other MLA users, I have uploaded a new Development Version dated 20151215 that contains the new mla-featured-field-shortcode.php.txt example plugin. To get the Development Version, follow the instructions in this earlier topic:

Shortcode not working in (special) widget

I will mark this topic resolved when the new plugin goes out with the next MLA version. Thanks for your help with this new example plugin.

I have released MLA version 2.22, which contains the “featured field shortcode” example plugin. I am marking this topic resolved, but please update it if you have any problems or further questions regarding the example plugin.
