Custom Caption for Featured Images

Setup: Copy the function to your functions.php or a code-block!

Output a Custom Image-Caption with the new Bricks Dynamic-Data Function Return Value Option! I’ve created a function for you ready to copy & paste to easily grab some extra information from your featured Image! You would need to add that function either in a CodeBlock, or in your functions.php or if you prefer a Plugin like AdvancedScripts, WPCodeBox or CodeSnippets you can also go with them!

<?php
function getFeaturedImageMeta($type = 'caption'){
    if ($type == 'alt'){
        return get_post_meta( get_post_thumbnail_id(), '_wp_attachment_image_alt', true );
    } else if ($type == 'title'){
        return get_post(get_post_thumbnail_id())->post_title;
    } else if ($type == 'description'){
        return get_post(get_post_thumbnail_id())->post_content;
    } else if ($type == 'caption'){
        return get_post(get_post_thumbnail_id())->post_excerpt;
    } else {
        return 'unknown Parameter';
    }
}
?>

Use the Dynamic-Data function return value

To make it work you just need to use Bricks' built in Dynamic-Data, like so. Without passing any parameters it outputs the caption of the featured Image.

{echo:getFeaturedImageMeta}

You can use the following parameters, which will output the corresponding texts:

{echo:getFeaturedImageMeta('alt')}

echo:getFeaturedImageMeta('title')}

echo:getFeaturedImageMeta('description')}

echo:getFeaturedImageMeta('caption')}
