One way to use the post title as the featured image alt text in WordPress is by adding the following code to your functions.php file:

function featured_image_alt_text($content) {
    global $post;
    if (has_post_thumbnail($post->ID)) {
        $thumbnail = wp_get_attachment_image_src(get_post_thumbnail_id($post->ID), 'full');
        $content = str_replace('<img', '<img alt="' . esc_attr($post->post_title) . '"', $content);
    return $content;
add_filter('the_content', 'featured_image_alt_text');

This code adds a filter to the content of the post and checks if there is a featured image. If there is, it replaces the alt text of the image with the post title. Note that this code will only affect images added to the content area using WordPress's default editor.

If you are using a different method to add featured images to your posts, you may need to modify the code to suit your specific setup.

To use this code, follow these steps:

  1. Log in to your WordPress admin area.
  2. Go to Appearance > Theme Editor.
  3. Find the file named "functions.php" on the right-hand side.
  4. Click on "functions.php" to open it in the code editor.
  5. Add the code mentioned above at the end of the file.
  6. Click on the "Update File" button to save the changes.

Now, whenever you add a featured image to a post, the alt text of the image will automatically be populated with the post title. Remember to clear any cache or refresh your website to see the changes in effect.

Please note that modifying the theme's files directly may result in the loss of changes when updating the theme. It is recommended to use a child theme or a custom plugin to add such code snippets.

Additionally, If you prefer to use a plugin, you can install and activate the "Yoast SEO" plugin. This plugin allows you to easily modify the alt text of the featured image to be the post title.

Here are the steps to use the post title as the featured image alt text using the Yoast SEO plugin:

  1. Install and activate the Yoast SEO plugin from the WordPress plugin repository.
  2. Go to the post editor and locate the featured image section. You can find this section on the right-hand side of the post editor.
  3. Click on the "Set featured image" button and select the desired image.
  4. After selecting the featured image, scroll down to the meta box titled "Yoast SEO".
  5. Click on the "Edit snippet" button within the Yoast SEO meta box.
  6. In the snippet editor, you will see an input field for the image alt text. By default, it may show a variable like %%alt%%. Change the input to %%title%% to use the post title as the alt text for the featured image.
  7. Update or publish the post.

Now, when you view the post, the alt text for the featured image will be automatically set to the post title.

Remember to save the changes to the post after modifying the alt text.
