This project is no longer actively maintained.

Dynamically adds multiple featured image (post thumbnail) functionality to posts, pages and custom post types.

Overview

Why limit yourself to only one featured image if you can do some awesome stuffs with multiple featured image? Dynamic Featured Image enables the option to have MULTIPLE featured images within a post or page. It allows you to add different number of featured images to each post and page that can be collected by the various theme functions. This is especially helpful when you use other plugins, post thumbnails or sliders that use featured images.

2. Activate the plugin through the Plugins menu in WordPress.
3. If you don't see new featured image box, click Screen Options in the upper right corner of your wordpress admin and make sure that the Featured Image 2 box is selected.

Allowing DFI only in specific post types

You can use dfi_post_types filter to allow DFI only in a specific post types.

function allowed_post_types() {
    return array('post'); //show DFI only in post
}
add_filter('dfi_post_types', 'allowed_post_types');

Blocking DFI

Use dfi_post_type_user_filter filter to block DFI from post types.

function blocked_post_types() {
    return array('page'); //block DFI in page
}
add_filter('dfi_post_type_user_filter', 'blocked_post_types');

Changing the metabox default text

Use dfi_set_metabox_title filter to change the metabox default title (Featured Image)

function set_metabox_title( $title ) {
    return "My custom metabox title";
}
add_filter('dfi_set_metabox_title', 'set_metabox_title');

Translation Guidelines

All translations live in the languages folder.

If you are interested in translating the plugin in your language, first make sure if the translation is not already available. The name of the file is important because there’s a particular format you should follow for consistency. For example, if you’re translating Nepali for Nepal, the file should be dynamic-featured-image-ne_NP.po – dynamic-featured-image for the plugin itself, ne for the language and NP for the country.

Development

1. Install PHPUnit and composer if you haven't already.
