I've made a custom field for my product categories so that I could select icons accordingly using ACF plugin. I called all the categories like this (But the values of the custom fields return nothing as I've tried var_dumping it):
<?php
$orderby = 'date';
$order = 'DESC';
$hide_empty = false ;
$cat_args = array(
'orderby' => $orderby,
'order' => $order,
'hide_empty' => $hide_empty,
);
$product_categories = get_terms( 'product_cat', $cat_args );
if( !empty($product_categories) ){
foreach ($product_categories as $key => $category) {
$icon = get_field('icon_classname');
if (empty($icon)) { $icon = 'flaticon-002-coat'; }
?>
<div class="cat-item">
<div class="cat cat-1">
<div class="cat-wrap">
<a class="category" href="<?php echo get_term_link($category); ?>">
<i class="icon fimanager <?php echo $icon; ?>"></i>
<span class="cat-title"><?php echo $category->name; ?></span>
</a>
</div>
</div>
</div>
<?php
} wp_reset_postdata();
}
?>
please check it :
you should replace these two lines :
foreach( $product_categories as $cat) {
$icon = get_field('icon_classname', 'category_'.$cat->term_id);

I'm trying to hide sub-categories under categories, but I'm not able to. I'm looking to create a follow menu. How can I do that?
add_action('zigcy_lite_product_cat_menu','zigcy_lite_add_browse_categories_nav_menu_items');
if ( ! function_exists( 'zigcy_lite_add_browse_categories_nav_menu_items' ) ) {
function zigcy_lite_add_browse_categories_nav_menu_items() {
if ( ! class_exists( 'WooCommerce' ) )
return;
$product_categories = get_terms( 'product_cat');
$count = count($product_categories);
?>
<div class="browse-category-wrap">
<div class="browse-category">
<i class="lnr lnr-menu"></i>
<?php esc_html_e('Shop by Gender','zigcy-lite'); ?>
</div>
<div class="categorylist">
<ul>
<?php
foreach( $product_categories as $product_category ) {
$cat_name = $product_category->name;
$cat_id = $product_category->term_id;
?>
<li><?php echo esc_html($cat_name); ?> </li>
<?php } ?>
</ul>
</div>
</div>
<?php

}

Check the get_terms reference at: https://codex.wordpress.org/Function_Reference/get_terms
You can pass the "parent" argument to only get the top level categories:
$args = array( 'taxonomy' => 'product_cat', 'hide_empty' => true, 'parent' => 0 );
$product_categories = get_terms('product_cat', $args);
foreach ($product_categories as $term) {
echo '<li>' . $term->name . ' ('.$term->count.')</li>';
}
I am trying to get grouped products highest price so that i can show only highest price on custom template page.I am using WP_Query to get list of products.
Here is the snippet:
$series_term = $_GET['series'];
$args=array(
'series' => $term_name->slug,
'post_type' => 'product',
'posts_per_page' => 8,
'filter' =>$valuecol,
'tax_query' => array(
array(
'taxonomy' => 'product_cat',
'field' => 'slug',
'terms' => array( 'hidden' ), // Don't display products in the knives category on the shop page
'operator' => 'NOT IN'
)
)
);
// $do_not_duplicate[] = $post->ID;
$my_query = null;
$my_query = new WP_Query($args);
/* Start the Loop */
while ($my_query->have_posts()) : $my_query->the_post();
$feat_prod_img = wp_get_attachment_image_src(get_post_thumbnail_id(), 'post-thumb-single');
$feat_product_img = wp_get_attachment_url( get_post_thumbnail_id($my_query->post->ID) );
?>
<div class="col-md-3 col-sm-4 col-xs-6">
<div class="product-detail">
<div class="product-thmbnial">
<a href="<?php the_permalink(); ?>">
<img src="<?php $src=$feat_product_img; echo image_product_resize_crop( $src, $w=440, $h=275, $dest = null, $override = false, $createNewIfExists = false ); ?>" alt="<?php the_title(); ?>"/>
</a>
</div>
<div class="info"><p><?php the_title(); ?><br/>
<span>
<?php $wp_product = new WC_Product( get_the_ID() );
echo get_woocommerce_currency_symbol(); ?></sup><?php
echo $wp_product->get_price();?></span></p></div>
</div>
</div>
<?php endwhile; ?>
I want grouped product highest price to show in place of $wp_product->get_price();
I tried to get children products and but the array is empty.
foreach ( $wp_product->get_children() as $child_id ) {
$child_prices[] = get_post_meta( $child_id, '_price', true );
}
can anyone suggest me how i can get highest price.
Thanks in advance.
I found the solution.. I tried the same solution earlier but that time it wasn't working.
Here is the fix:
$series_term = $_GET['series'];
$args=array(
'series' => $term_name->slug,

'posts_per_page' => 8,

'tax_query' => array(
array(
'taxonomy' => 'product_cat',
'field' => 'slug',
'terms' => array( 'hidden' ), // Don't display products in the knives category on the shop page
'operator' => 'NOT IN'
)
)
);
// $do_not_duplicate[] = $post->ID;
$my_query = null;
$my_query = new WP_Query($args);
/* Start the Loop */
while ($my_query->have_posts()) : $my_query->the_post();
$feat_prod_img = wp_get_attachment_image_src(get_post_thumbnail_id(), 'post-thumb-single');
$feat_product_img = wp_get_attachment_url( get_post_thumbnail_id($my_query->post->ID) );
?>
<div class="col-md-3 col-sm-4 col-xs-6">
<div class="product-detail">

I am building a shopping website and I am trying to put a shortcode in that will show the customer a buy button and the quantity of the product the customer wants to purchase. On my post page the shortcode works fine:
http://warringah-plastics.com.au/blog/dt_catalog/recess-gasket-large/
but on the archive page:
http://warringah-plastics.com.au/store/
the shortcode id displayed as text and not the actual button and quantity e.g. [add_to_cart item="FPROWAR-160713-1" showprice="no" quantity="user:1" ajax="yes" ].
The code that works in the post page is this:
<?php
$my_textbox_value = mtbxr_val("shopping_shortcode");
echo do_shortcode("$my_textbox_value");
?>
but it just displays the shortcode text on that archive page. Anyone have any ideas? Much appreciated,

echo do_shortcode("$my_textbox_value");
?>
</div>
</div>
</div>
Try using single quotes in the do_shortcode call, like so:
echo do_shortcode('$my_textbox_value');
More likely though is that the shortcode isn't defined on the archive page so you'd need to look at where it is being instantiated to see if that is the issue. Normally when a shortcode just echoes out the content it means that shortcode doesn't exist. You can test easily enough by using the shortcode_exists() function:
<?php if ( shortcode_exists( 'add_to_cart' ) ) { echo "The shortcode exists";} ?>
If that doesn't work then you know the issue is with the shortcode not being registered on your archives page. If it does work then you know it's something with the format of the content being passed to the shortcode.
Add this to your functions.php
// Allow shortcodes on widgets
add_filter('widget_text','do_shortcode');
// Allow shortcodes on pages (not tested, but should work)
add_filter('the_content','do_shortcode');
Typically your shortcode is getting registered in a plugin or your theme's functions.php file. In a plugin it's often something like:
add_action('init', 'register_my_shortcode');
function register_my_shortcode(){
add_shortcode('my_shortcode', 'do_my_shortcode');
}
And then you'd have a function do_my_short_code() that actually outputs the content. With something like that the shortcode is getting registered via the 'init' hook (http://codex.wordpress.org/Plugin_API/Action_Reference) which is called before WP has started figuring out what template to use, what content to output, etc.
But some plugins will register the shortcode in a way that it is only available on pages / posts where it's going to potentially be used. For example, I can think of one plugin where they register the shortcode and enqueue some javascripts in the same function. That function checks to see if you're on a particular page before it executes so that the js files are not included unnecessarily all over the place. Since the shortcode registration takes place in the same function it means the shortcode only exists on those pages.
Anyhow, if the shortcode is showing as existing on your archives page you know that isn't the problem, so check that first and let me know what you find.
