How to display Woocommerce Category image?

问题:

I use this code in PHP:

$idcat = 147;
$thumbnail_id = get_woocommerce_term_meta( $idcat, 'thumbnail_id', true );
$image = wp_get_attachment_url( $thumbnail_id );
echo '<img src="'.$image.'" alt="" width="762" height="365" />';

Where 147 is the current ID manually set, but i need to current id in other categories

Any suggest?

回答1:

To display the category image for the currently displayed category in archive-product.php, use the current category term_id when is_product_category() is true:

// verify that this is a product category page
if ( is_product_category() ){
    global $wp_query;

    // get the query object
    $cat = $wp_query->get_queried_object();

    // get the thumbnail id using the queried category term_id
    $thumbnail_id = get_woocommerce_term_meta( $cat->term_id, 'thumbnail_id', true ); 

    // get the image URL
    $image = wp_get_attachment_url( $thumbnail_id ); 

    // print the IMG HTML
    echo "<img src='{$image}' alt='' width='762' height='365' />";
}

You may also used foreach loop for display category image and etc from parent category given by parent id.

for example, i am giving 74 id of parent category, then i will display the image from child category and its slug also.

**<?php
$catTerms = get_terms('product_cat', array('hide_empty' => 0, 'orderby' => 'ASC', 'child_of'=>'74'));
foreach($catTerms as $catTerm) : ?>
<?php $thumbnail_id = get_woocommerce_term_meta( $catTerm->term_id, 'thumbnail_id', true ); 

// get the image URL
$image = wp_get_attachment_url( $thumbnail_id );  ?>
<li><img src="<?php echo $image; ?>" width="152" height="245"/><span><?php echo $catTerm->name; ?></span></li>
<?php endforeach; ?>**

To prevent full size category images slowing page down, you can use smaller images with wp_get_attachment_image_src():

<?php 

$thumbnail_id = get_woocommerce_term_meta( $term->term_id, 'thumbnail_id', true );

// get the medium-sized image url
$image = wp_get_attachment_image_src( $thumbnail_id, 'medium' );

// Output in img tag
echo '<img src="' . $image[0] . '" alt="" />'; 

// Or as a background for a div
echo '<div class="image" style="background-image: url("' . $image[0] .'")"></div>';

?>

EDIT: Fixed variable name and missing quote

From the WooCommerce page:

// WooCommerce – display category image on category archive

add_action( 'woocommerce_archive_description', 'woocommerce_category_image', 2 );
function woocommerce_category_image() {
    if ( is_product_category() ){
      global $wp_query;
      $cat = $wp_query->get_queried_object();
      $thumbnail_id = get_woocommerce_term_meta( $cat->term_id, 'thumbnail_id', true );
      $image = wp_get_attachment_url( $thumbnail_id );
      if ( $image ) {
          echo '<img src="' . $image . '" alt="" />';
      }
  }
}
