Question

请告诉我哪里出错了。产品特色图片未显示。

   $args = array( 'post_type' => 'product', 'posts_per_page' => 80, 'product_cat' => 'profiler', 'orderby' => 'rand' );

    $loop = new WP_Query( $args );

   while ( $loop->have_posts() ) : $loop->the_post(); global $product; ?>

    <div class="dvThumb col-xs-4 col-sm-3 col-md-3 profiler-select profiler<?php echo the_title(); ?>" data-profile="<?php echo $loop->post->ID; ?>">

    <img src="<?php  get_the_post_thumbnail($loop->post->ID); ?>" data-id="<?php echo $loop->post->ID; ?>">

    <p><?php the_title(); ?></p>

    <span class="price"><?php echo $product->get_price_html(); ?></span>                    
    </div>

我已在后端添加了精选图片

Answer 1

我得到了解决方案。我试过这个。

- (void)downloadItems
{
    // Download the json file
    NSURL *jsonFileUrl = [NSURL URLWithString:@"http://myhost.com/test.php"];

    // Create the request
    NSURLRequest *urlRequest = [[NSURLRequest alloc] initWithURL:jsonFileUrl];

    // Create the NSURLConnection
    [NSURLConnection connectionWithRequest:urlRequest delegate:self];
}

#pragma mark NSURLConnectionDataProtocol Methods

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
    // Initialize the data object
    _downloadedData = [[NSMutableData alloc] init];
}

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
    // Append the newly downloaded data
    [_downloadedData appendData:data];
}

- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
    // Create an array to store the locations
    NSMutableArray *_locations = [[NSMutableArray alloc] init];

    // Parse the JSON that came in
    NSError *error;
    NSArray *jsonArray = [NSJSONSerialization JSONObjectWithData:_downloadedData options:NSJSONReadingAllowFragments error:&error];

    // Loop through Json objects, create question objects and add them to our questions array
    for (int i = 0; i < jsonArray.count; i++)
    {
        NSDictionary *jsonElement = jsonArray[i];

        // Create a new location object and set its props to JsonElement properties
        Location *newLocation = [[Location alloc] init];
        newLocation.idS = jsonElement[@"idStatistic"];
        newLocation.temp = jsonElement[@"temp"];
        newLocation.hum = jsonElement[@"hum"];
        newLocation.date_time = jsonElement[@"date_time"];

        // Add this question to the locations array
        [_locations addObject:newLocation];
    }

    // Ready to notify delegate that data is ready and pass back items
    if (self.delegate)
    {
        [self.delegate itemsDownloaded:_locations];
    }
}

Answer 2

get_the_post_thumbnail函数返回html而不是特色图片的网址。您应该使用get_post_thumbnail_id获取精选图片的帖子ID，然后使用wp_get_attachment_image_src获取精选图片的网址。

试试这个：

<?php
$args = array( 'post_type' => 'product', 'posts_per_page' => 80, 'product_cat' => 'profiler', 'orderby' => 'rand' );

$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post(); global $product; ?>
    <div class="dvThumb col-xs-4 col-sm-3 col-md-3 profiler-select profiler<?php echo the_title(); ?>" data-profile="<?php echo $loop->post->ID; ?>">
        <?php $featured_image = wp_get_attachment_image_src( get_post_thumbnail_id($loop->post->ID)); ?>
        <?php if($featured_image) { ?>
        <img src="<?php $featured_image[0]; ?>" data-id="<?php echo $loop->post->ID; ?>">
        <?php } ?>
        <p><?php the_title(); ?></p>
        <span class="price"><?php echo $product->get_price_html(); ?></span>
    </div>
<?php endwhile; ?>

get_the_post_thumbnail()

Answer 4

在WC 3.0+版本中，图像可以通过以下代码获得。

$image_url = wp_get_attachment_image_src( get_post_thumbnail_id( $item->get_product_id() ), 'single-post-thumbnail' );
echo $image_url[0]

Answer 5

我做到了，效果很好

<?php if ( has_post_thumbnail() ) { ?>
<a href="<?php the_permalink(); ?>" title="<?php the_title_attribute(); ?>"><?php the_post_thumbnail(); ?></a>
<?php } ?>

Answer 6

我遇到了同样的问题，并通过使用默认的woocommerce挂钩显示产品图片来解决了该问题。

while ( $loop->have_posts() ) : $loop->the_post();
   echo woocommerce_get_product_thumbnail('woocommerce_full_size');
endwhile;

可用参数：

woocommerce_thumbnail
woocommerce_full_size

Answer 7

这应该可以解决问题。经过测试和工作。

<?php
    $product_meta = get_post_meta($post_id);
    echo wp_get_attachment_image( $product_meta['_thumbnail_id'][0]), 'full' );
?>

您可以根据需要更改参数。

Answer 8

这里的答案太复杂了。这是我最近使用过的东西：

<?php global $product; ?>
<img src="<?php echo wp_get_attachment_url( $product->get_image_id() ); ?>" />

使用wp_get_attachment_url()显示
