How Do I Add a Price Filter in WordPress?

Adding a price filter to your WordPress blog is a simple process. First, create a new plugin file called price.php and add the following code to it:

get_var( ‘wp_price_filter’, $item ); return $price; } /** * Add a price filter to your blog. * @param int $price The price of the item. * @return bool Whether the price was added to the filter. */ function addPriceFilter( $item, $price ) { global $wpdb; $filter = $wpdb->get_var( ‘wp_price_filter’, $item ); if( !empty( $filter ) ) { if( $price <= $filter [ 'price' ] ) { $filter [ 'price' ] = $price; } } return true; }.Next, add the following code to the theme or plugin file where you want the price filter to be active. This code will initialize the price filter and add the price of an item to the filter:add_filter( 'price', 'getPrice' ); add_filter( 'price_filter', 'addPriceFilter' );Finally, you need to call the function to add the price filter when displaying an item. You can do this in the loop of an item’s get_template_part() function, like this:get_var( ‘wp_price_filter’, $item ); $filter [ ‘price’ ] = $item->get_price(); } // Display the item. $item->display(); }.
