Newsletters: Filter – wpml_post_thumbnail_img_style

Description

The wpml_post_thumbnail_img_style provides a custom inline style for the post thumbnail <img> tag. You can use this filter to add inline style based on post type or by determining the $post object and defining your own conditions. It will be added to the emails, as inline style.

It is useful when you want to modify the styling of your newsletter images and ensure the formatting remains consistent during email forwarding, as inline styles are used instead of embedded CSS classes or external styles in your email template.

Usage

<?php add_filter('wpml_post_thumbnail_img_style', 'child_theme_get_post_thumbnail_img_style', 10, 4); ?>

Arguments

• $style – The default style (from alignment/hspace, or empty).
• $post_id – The post ID.
• $post_type – The post type.
• $post –  The full post object.

Example

<?php
/**
* Provide a custom inline style for the post thumbnail <img> tag.

* @param int $post_id The post ID.
