在WooCommerce中显示产品类别的随机产品缩略图 [英] Display a random product thumbnail for a product category in WooCommerce
问题描述
我正在尝试拉一个随机的产品缩略图,以在我的页面之一上显示为图像。我似乎找不到可行的方法,并尝试了此和此帖子
I am trying to pull a random product thumbnail to display as an image on one of my pages. I can't seem to find a way that works, and have tried the solutions from this and this post.
在div中回显它也是有益的。
It would be beneficial to echo it out in a div as well.
这是我目前正在尝试的方法,但是我仍然不确定如何执行此操作。
Here is what I am currently trying but I'm still unsure how to do this.
functions.php:
function get_random_thumbnails_for_reg(){
if(is_page(381)){
$args = array(
'tax_query' => array(
array(
'taxonomy' => 'product_cat',
'field' => 'slug',
'terms' => 'allison-1000-gm-duramax-series'
)
)
);
$random_products = get_posts( $args );
foreach ( $random_products as $post ) : setup_postdata( $post );
?>
<div id="randomPic"><a href="<?php the_permalink(); ?>"><?php the_post_thumbnail(); ?></a></div>
<?php
endforeach;
wp_reset_postdata();
}
}
add_action('wp_footer', 'get_random_thumbnails_for_reg', 50);
推荐答案
好了,经过一些测试,我发现它可以在其他环境下工作模块化的方式。我创建了一个自定义的简码,可以根据产品类别**随机显示一个产品缩略图。
Ok after some testing I got it working in a different modular way. I have created a custom shortcode that displays randomly one product thumbnail based on a product category**.
此简码有2个参数:
- 产品类别:
猫
- 图像
size
(可以是:'shop_thumbnail'
,'shop_catalog'
或'shop_single'
)
- The product category slug:
cat
- The image
size
(can be:'shop_thumbnail'
,'shop_catalog'
or'shop_single'
)
然后,我在您的自定义函数中使用此短代码,将其链接到 wp_footer
操作钩。
Then I use this short code in your custom function hooked in wp_footer
action hook.
这是代码:
// Creating a shortcode that displays a random product image/thumbail
if( !function_exists('custom_shortcode_random_thumbnail') ) {
function custom_shortcode_random_thumbnail( $atts ) {
// Shortcode attributes
$atts = shortcode_atts(
array(
'cat' => '', // product category shortcode attribute
'size' => 'shop_thumbnail', // Default image size
),
$atts, 'random_thumbnail'
);
// Get products randomly (from a specific product category)
$random_post = get_posts( array(
'posts_per_page' => 1,
'post_type' => 'product',
'orderby' => 'rand',
'post_status' => 'published',
'tax_query' => array( array(
'taxonomy' => 'product_cat',
'field' => 'slug',
'terms' => $atts['cat'],
) )
) );
// Get an instance of the WC_Product object
$product = wc_get_product($random_post[0]->ID);
// The Product permalink
$product_permalink = $product->get_permalink();
// The Product image. Size can be: 1. 'shop_thumbnail', 2. 'shop_catalog' or 3. 'shop_single'
$product_image = $product->get_image( $atts['size'] );
// The output
return '<div id="random-pic"><a href="' . $product_permalink . '">' . $product_image . '</a></div>';
}
add_shortcode( 'random_thumbnail', 'custom_shortcode_random_thumbnail' );
}
// Using the shortcode to display a random product image
function get_random_thumbnails_for_reg(){
// Only for page ID 381
if( ! is_page( 381 ) ) return;
echo do_shortcode( "[random_thumbnail cat='clothing']" );
}
add_action('wp_footer', 'get_random_thumbnails_for_reg', 50);
代码会进入您的活动子主题(或主题)的function.php文件中,或者
此代码已经过测试并且有效
This code is tested and works
