Adding meta boxes to a plugin
-
I’m using the Category Grid View Gallery plugin (https://www.ads-software.com/extend/plugins/category-grid-view-gallery/) which uses featured images from posts to create a grid gallery. When you hover the images, the plugin views the Title of the post behind the featured image. I would like to add a short description to each post, displayed beneath the title when hovering an image. I’m trying to solve this by adding a text field using the post meta function to the post editor, but I can’t figure out how. I have taken a look at the post_meta function (https://codex.www.ads-software.com/Function_Reference/post_meta_Function_Examples), which I assume is what I need, but I’m still confused about what I have to do. Any ideas, or do you know about any relevant guides?
