Wordpress: Get Attachment URL by Size

function get_attachment_url_by_size( $attachment_id, $size = 'thumbnail' ) {
    $image_src = wp_get_attachment_image_src( $attachment_id, $size );
    return $image_src[0];
}

• Step 1: Define a function called get_attachment_url_by_size that takes two parameters: $attachment_id and $size, with a default value of 'thumbnail'.

• Step 2: Within the function, use the wp_get_attachment_image_src function to retrieve the image source (URL) for the specified attachment ID and size.

• Step 3: Return the URL of the image source by accessing the first element of the array returned by wp_get_attachment_image_src.

This function allows you to retrieve the URL of an attachment by specifying its ID and size within a WordPress environment.
