Why won't the image resize in woocommerce?

Question

WooCommerce

Good afternoon.
I set the sizes in the admin panel


In functions.php I set the sizes, but already 660, to see what sizes will be displayed on the product pages.

add_filter( 'woocommerce_get_image_size_thumbnail', function ( $size ) {
  return array(
    'width'  => 660,
    'height' => 660,
    'crop'   => 1,
  );
} );
add_theme_support( 'woocommerce', array(
  'thumbnail_image_width' => 660,
  'single_image_width'    => 660,
) );

Then, using the regenerate thumbnails plugin, I changed the size of the images, but on the product page, the picture still has a size of 300x300.

What could be the problem?
Thanks in advance.

Answer 1

I created a woocommerce/single-product/product-image.php file, and copied the content from the same file from the woocommerce plugin.
Inside there is a wc_get_gallery_image_html function.
I created another wc_get_gallery_image_html_custom function in functions.php and copied the content from the original.
This is the content of product-image.php:

<div class="<?php echo esc_attr( implode( ' ', array_map( 'sanitize_html_class', $wrapper_classes ) ) ); ?>"
     data-columns="<?php echo esc_attr( $columns ); ?>" style="opacity: 0; transition: opacity .25s ease-in-out;">
  <figure class="woocommerce-product-gallery__wrapper">
    <?php
    if ( $product->get_image_id() ) {
      $html = wc_get_gallery_image_html_custom( $post_thumbnail_id, true );
    } else {
      $html = '<div class="woocommerce-product-gallery__image--placeholder">';
      $html .= '<img src="'.get_the_post_thumbnail_uri($product->id, 'full').'" class="wp-post-image" />';
      $html .= '</div>';
    }
    echo apply_filters( 'woocommerce_single_product_image_thumbnail_html', $html, $post_thumbnail_id ); // phpcs:disable WordPress.XSS.EscapeOutput.OutputNotEscaped
    do_action( 'woocommerce_product_thumbnails' );
    ?>
  </figure>
</div>

And here is the content of the function:

function wc_get_gallery_image_html_custom( $attachment_id, $main_image = false ) {
  $flexslider        = (bool) apply_filters( 'woocommerce_single_product_flexslider_enabled', get_theme_support( 'wc-product-gallery-slider' ) );
  $gallery_thumbnail = wc_get_image_size( 'gallery_thumbnail' );
  $thumbnail_size    = apply_filters( 'woocommerce_gallery_thumbnail_size', array(
    $gallery_thumbnail['width'],
    $gallery_thumbnail['height']
  ) );
  $image_size        = apply_filters( 'woocommerce_gallery_image_size', $flexslider || $main_image ? 'woocommerce_single' : $thumbnail_size );
  $full_size         = apply_filters( 'woocommerce_gallery_full_size', apply_filters( 'woocommerce_product_thumbnails_large_size', 'full' ) );
  $thumbnail_src     = wp_get_attachment_image_src( $attachment_id, $thumbnail_size );
  $full_src          = wp_get_attachment_image_src( $attachment_id, $full_size );
  $alt_text          = trim( wp_strip_all_tags( get_post_meta( $attachment_id, '_wp_attachment_image_alt', true ) ) );
  $image             = wp_get_attachment_image( $attachment_id, $full_size, false, apply_filters( 'woocommerce_gallery_image_html_attachment_image_params', array(
    'title'                   => _wp_specialchars( get_post_field( 'post_title', $attachment_id ), ENT_QUOTES, 'UTF-8', true ),
    'data-caption'            => _wp_specialchars( get_post_field( 'post_excerpt', $attachment_id ), ENT_QUOTES, 'UTF-8', true ),
    'data-src'                => esc_url( $full_src[0] ),
    'data-large_image'        => esc_url( $full_src[0] ),
    'data-large_image_width'  => esc_attr( $full_src[1] ),
    'data-large_image_height' => esc_attr( $full_src[2] ),
    'class'                   => esc_attr( $main_image ? 'wp-post-image' : '' ),
  ), $attachment_id, $image_size, $main_image ) );
  return '<div data-thumb="' . esc_url( $thumbnail_src[0] ) . '" data-thumb-alt="' . esc_attr( $alt_text ) . '" class="woocommerce-product-gallery__image"><a href="' . esc_url( $full_src[0] ) . '">' . $image . '</a></div>';
}

I changed image_size to full_size
