Creating the Plugin

To use HTML for ordered and unordered lists in your Envira caption, just add the following code to a new file at wp-content/plugins/envira-text-format-for-captions.php.

<?php
/**
* Plugin Name: Envira Gallery - Text format for captions
* Plugin URI: https://enviragallery.com
* Version: 1.0.0
* Author: Envira Gallery Team
* Author URI: https://enviragallery.com
* Description: Allow certain HTML characters in the caption area under gallery images
*/

add_filter( 'envira_gallery_image_caption_allowed_html_tags', 'example_envira_gallery_image_caption_allowed_html_tags', 5, 5 );
function example_envira_gallery_image_caption_allowed_html_tags( $allowed_tags, $id, $item, $data, $i ) {
	/* allowed tags is an array */
	$allowed_tags['li'] = array();
	$allowed_tags['ul'] = array();
	$allowed_tags['ol'] = array();
	return $allowed_tags;
}

If you’re unsure how to create a plugin file, follow these steps below:

1. Open a text file and make sure that it is a plain text document. You can use a plain text editor like Notepad or a code editor of your choice.
2. Next, copy and paste the code shown below that matches the page builder you’re using into the file and save the file as envira-text-format-for-captions.php
3. Once you’ve saved the file you can easily upload this directly to your /plugins directory on your server using FTP or you can right-click on the text document and zip (or compress).
4. Finally, log in to your WordPress dashboard and go to Plugins » Add New » Upload Plugin and upload the .zip file you just created in the previous step.

Activate the Plugin

Your next step is to activate the plugin you just uploaded. Simply navigate to the Plugins from within your WordPress dashboard and activate the Envira Gallery – Text format for captions plugin.
