icinga2 disable swap check

icinga2

I had to disable swap check for one of my hosts.
This is how I’v done it.

nano /etc/icinga2/conf.d/services.conf
apply Service "swap" {
  import "generic-service"

  check_command = "swap"

  assign where host.name == NodeName
  ignore where host.name == "my_host"
}
service icinga2 restart

on icinga2 service.conf I’v added the following line ignore where host.name == “my_host” and then restarted icinga2

woocommerce remove shipping if product of X shipping method is in cart

Wordpress,

So, if we need to hide shipping, if the buyer has some item of specific shipping class, in this case ‘recolha-em-armazem’, we can use this code, on functions.php of our theme. 

// Replace 'shipping-class' with the specific shipping class you want to force the local pick up upon
// To make it more readable, replace $shippingClass with your class name, eg : $hugeProducts

function my_hide_shipping_when_local_is_available( $rates ) {
    $cart_items = WC()->cart->get_cart();
    $shippingClass = false;
    
    foreach ( $cart_items as $cart_item ) {
		$product = $cart_item['data'];
		$class   = $product->get_shipping_class();
		
		if ( 'recolha-em-armazem' == $class ) {
			$shippingClass = true;
		}
	}
    
	$local = array();
	foreach ( $rates as $rate_id => $rate ) {
		if ('local_pickup' === $rate->method_id ) {
            $local[ $rate_id ] = $rate;
        }
	}
    
    if ( !empty($local) && ($shippingClass == true) ) {
        return $local;
    } else {
        return $rates;
    }

}

add_filter( 'woocommerce_package_rates', 'my_hide_shipping_when_local_is_available', 100 );

As seen on https://gist.github.com/kane-c/5e4d53601564ed667fb9

I had to create a custom js code to select the shipping method, ’cause buyer wasn’t able to select the shipping method… this snippet might not be need… or u need to tweak it a little bit…

jQuery(document).ready(function( $ ){ 
   if ( $('#shipping_method li').length == 1 )
   {
      setInterval(function() {
 
jQuery('#shipping_method_0_local_pickup3').clone().attr('type','radio').insertAfter('#shipping_method_0_local_pickup3').prev().remove();

      jQuery('#shipping_method_0_local_pickup3').attr('checked',true);
      jQuery('p.woocommerce-shipping-destination').hide();
      jQuery('form.woocommerce-shipping-calculator').hide();
              
              }, 500);
    }
