Obtener ruta de miniatura en lugar de etiqueta de imagen

Laminiaturaesesencialmente un archivo adjunto,por lo quepuede acercarse desdeese lado: ID debúsqueda con get_post_thumbnail_id() y obtenga datos con wp_get_attachment_image_src() ,así:

 if (has_post_thumbnail()) {
    $thumb = wp_get_attachment_image_src(get_post_thumbnail_id(), 'thumbnail_name');
    echo $thumb[0]; // thumbnail url
}

Thumbnail is essentially attachment so you can approach from that side - lookup ID with get_post_thumbnail_id() and fetch data with wp_get_attachment_image_src(), like this:

if (has_post_thumbnail()) {
    $thumb = wp_get_attachment_image_src(get_post_thumbnail_id(), 'thumbnail_name');
    echo $thumb[0]; // thumbnail url
}

(source)

 get_the_post_thumbnail_url($recent['ID']);
 

¡Lo anteriorme sirvió!Tuve que adivinar lafunción y ¡funcionómágicamente!

Esbuenomencionar que utilicéelbucle get_recent_postsen elproceso.

get_the_post_thumbnail_url($recent['ID']);

The above did the trick for me! I had to guess the function and it magically worked!

Its is good to mention that I used get_recent_posts loop in the process.

Unmétodo sería convertirtodo lo que se devuelva de get_the_post_thumbnail()en un objeto yextraerel atributo src:

 $thumbnail = new SimpleXMLElement( get_the_post_thumbnail( $postid ) );
print $thumbnail->attributes()->src;
 

One method would be to convert whatever is returned from get_the_post_thumbnail() to an object, and pull the src attribute:

$thumbnail = new SimpleXMLElement( get_the_post_thumbnail( $postid ) );
print $thumbnail->attributes()->src;

When I need to display a thumbnail that is attached to a post gallery, I use a custom function in my functions.php. It might be over kill for your needs, but it should cover everything.

In this example, I retrieve all the images in a post's gallery, and then display each image in a list item. The list contains the thumbnail image wrapped in an anchor that links to the post the image came from. The output string can easily be customized to your needs.

function get_gallery_image_thumb_list($size){
global $post;
$args = array(
    'numberposts' => null,
    'post_parent' => $post->ID,
    'post_type' => 'attachment',
    'nopaging' => false,
    'post_mime_type' => 'image',
    'order' => 'ASC',
    'orderby' => 'menu_order ID',
    'post_status' => 'any'
);

$attachments =& get_children($args);
if ($attachments) {
    foreach($attachments as $attachment) {
        foreach($attachment as $attachment_key => $attachment_value) {

            $imageID = $attachment->ID;
            $imageTitle = $attachment->post_title;
            $imageCaption = $attachment->post_excerpt;
            $imageDescription = $attachment->post_content;
            $imageAlt = get_post_meta($imageID, '_wp_attachment_image_alt', true);
            $imageArray = wp_get_attachment_image_src($attachment_value, $size, false);
            $imageURI = $imageArray[0]; // 0 is the URI
            $imageWidth = $imageArray[1]; // 1 is the width
            $imageHeight = $imageArray[2]; // 2 is the height

            // Build the <img> string
            $ImgString = '<li><a href="' . get_permalink() . '" title="' . the_title("", "", false) . '"><img src="' . $imageURI . '" width="' . $imageWidth . '" height="' . $imageHeight . '" alt="' . $imageAlt . '" title="' . $imageTitle . '" /></a></li>';
            // Print the image
            echo $ImgString;
            break;
        }
    }
}

unset($args);}

Then call the function and pass in the size of image you want returned (thumbnail, medium, large or full) like so:

get_gallery_image_thumb_list("thumbnail");

This will need to be called in The Loop or a custom loop.
