Get the minimum variation price in WooCommerce - php

Question

I am a beginner trying to learn Wordpress and have a variable product with prices:
cod Rs 250
online Rs 200
I want to use the minimum price in my themes functions.php.
How will I be able to fetch or get the minimum value?
I want to use in the below code :
function filter_gateways($gateways){
$payment_NAME = 'cod'; //
$min_variation_price = ''; <--------------- minimum variation price
global $woocommerce;
foreach ($woocommerce->cart->cart_contents as $key => $values ) {
// Get the terms, i.e. category list using the ID of the product
$terms = get_the_terms( $values['product_id'], 'product_cat' );
// Because a product can have multiple categories, we need to iterate through the list of the products category for a match
foreach ($terms as $term) {
// 20 is the ID of the category for which we want to remove the payment gateway
if($term->term_id == $min_variation_price){
unset($gateways[$payment_NAME]);
// If you want to remove another payment gateway, add it here i.e. unset($gateways['cod']);
break;
}
break;
}
}
return $gateways;
}

To get the minimum variation active price in WooCommerce from a WC_Product_Variable object:
$variation_min_price = $product->get_variation_price();
It seems that you are trying here to unset 'cod' payment gateway when a cart item min variation price is matching with his product category ID.
Using the WordPress conditional function has_term() will really simplify your code (it accepts term Ids, term slugs or term names for any taxonomy (as 'product_cat' here for product categories).
I suppose that your function is hooked in woocommerce_available_payment_gateways filter hook…
I made some changes in your code as it's a bit outdated and with some errors:
add_filter('woocommerce_available_payment_gateways', 'conditional_payment_gateways', 10, 1);
function conditional_payment_gateways( $available_gateways ) {
// Not in backend (admin)
if( is_admin() )
return $available_gateways;
foreach (WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
// Get the WC_Product object
$product = wc_get_product($cart_item['product_id']);
// Only for variable products
if($product->is_type('variable')){
// Get the Variation "min" price
$variation_min_price = $product->get_variation_price();
// If the product category match with the variation 'min" price
if( has_term( $variation_min_price, 'product_cat', $cart_item['product_id'] ) ){
// Cash on delivery (cod) payment gateway
unset($available_gateways['cod']); // unset 'cod'
break; // stop the loop
}
}
}
return $available_gateways;
}
Code goes in functions.php file of your active child theme (or theme) or also in any plugin file.
This should work (but I can't really test it as it's very specific regarding the product categories ID and the min variation prices)…
All related price methods for variable product type:
// All prices: multidimensional array with all variation prices (including active prices, regular prices and sale prices).
$prices = $product->get_variation_prices();
$prices_for_display = $product->get_variation_prices( true ); // For display
// The min or max active price.
$min_price = $product->get_variation_price(); // Min active price
$min_price_for_display = $product->get_variation_price('min', true); // Min active price for display
$max_price = $product->get_variation_price('max'); // Max active price
$max_price_for_display = $product->get_variation_price('max', true); // Max active price for display
// The min or max regular price.
$min_price = $product->get_variation_regular_price(); // Min regular price
$min_price_for_display = $product->get_variation_regular_price('min', true); // Min regular price for display
$max_price = $product->get_variation_regular_price('max'); // Max regular price
$max_price_for_display = $product->get_variation_regular_price('max', true); // Max regular price for display
// The min or max sale price.
$min_price = $product->get_variation_sale_price(); // Min sale price
$min_price_for_display = $product->get_variation_sale_price('min', true); // Min sale price for display
$max_price = $product->get_variation_sale_price('max'); // Max sale price
$max_price_for_display = $product->get_variation_sale_price('max', true); // Max sale price for display

I think you are looking for that :
add_filter( 'woocommerce_variable_sale_price_html', 'get_min_variation_price_format', 10, 2 );
add_filter( 'woocommerce_variable_price_html', 'get_min_variation_price_format', 10, 2 );
function get_min_variation_price_format( $price, $product ) {
$min_variation_price = $product->get_variation_regular_price( 'min');
return wc_price($min_variation_price);
}
