Get featured image url in wordpress

Paula

Hi all,
I am trying to build a custom theme for one of my clients and required to get the featured image URL. I am familiar with the_post_thumbnail() function, but this function echoes the featured image with the Img tag.

Hi Paula you can get the featured image url with wp_get_attachment_image_src() function.

$image_data = wp_get_attachment_image_src(get_post_thumbnail_id());

Here the $image_data return false in case the featured image not found otherwise it will return an array (url, width, height, is_intermediate).

if($image_data) {
    // Featured image url
    $image = $image_data[0];
}

Please take a look on the wp_get_attachment_image_src() documentation to get more details.

you could also use the wp_get_attachment_url() function. This function reutrn the false or the image string.

$image = wp_get_attachment_url(get_post_thumbnail_id());
if($image) {
    echo $image;
}

If you are using the WordPress 4.4.0 or greater version then you can use the get_the_post_thumbnail_url() function to get the post featured image url.

$image_url = get_the_post_thumbnail_url( $post_id, 'thumbnail' );
