bw_get_attachment_thumbnail() – Get the "thumbnail" image for an attachment

You appear to be a bot. Output may be restricted

Description

Gets the "thumbnail" image for an attachment

This no longer sets the width and height of the image. Does this work when we want a really small image?

Usage

$string = bw_get_attachment_thumbnail( $post_id, $size, $atts );

Parameters

$post_id
( int ) required – ID of the attachment
$size
( mixed ) required – size of the required image
$atts
( array ) required – contains the title for the attachment

Returns

string $thumbnail – either an image or just the attachment file name

Source

1 to 21 of 21
function bw_get_attachment_thumbnail( $post_id, $size, $atts ) {
  $thumbnail_arr = wp_get_attachment_image_src( $post_id, $size, false );
  $thumbnail = bw_array_get( $thumbnail_arr, 0, null);
  $text = bw_array_get( $atts, "title", NULL );
  if ( $thumbnail ) {
    $thumbnail = bw_verify_file_from_url( $thumbnail );
  }
  if ( $thumbnail ) {
    $thumbnail_arr = bw_force_size( $thumbnail_arr, $size );
    $classes = "bw_thumbnail " . bw_get_post_class( $post_id );
    $extras = null;
    if ( $thumbnail_arr[1] && $thumbnail_arr[2] ) {
        $extras = kv( "loading", "lazy");
        }
    $thumbnail = retimage( $classes, $thumbnail, $text, $thumbnail_arr[1], $thumbnail_arr[2], $extras );
  } else {
    $thumbnail = wp_get_attachment_link( $post_id, $size, false, false );
  }
  bw_trace2( $thumbnail, 'thumbnail', true, BW_TRACE_VERBOSE );
  return $thumbnail;
