Filters available in WPPizza Add Ingredients

wppizza_ingredients_filter_email_styles

The below filter will *only* apply to emails (as emails need style declarations to be added inline). For Print templates, use the css input in WPPizza->Templates->Print in conjunction with your browsers element inspector

@param: array
@return: array

add_filter('wppizza_ingredients_filter_email_styles', 'myprefix_ingredients_filter_email_styles');

WordPress inbuilt ‘get_post_metadata’ filter

A snippet you could use to override the ‘half/half’ and/or ‘quarter’ options on a per size basis for any menu item.
I.e if you have a menu item with “small”, “medium”, “large” and “xxl” sizes and have enabled “whole”, “halfs” and “quarters” for this but do *not* want to have the “halfs” or “quarters” option available for the “small” size, you could do something like the below

@param: mixed
@param: int
@param: str
@return: mixed

/*
The below can be condensed somewhat , but for clarity 
we keep conditionals a bit more separate here in this example
*/
//Add the filter, using wordpress inbuilt 'get_post_metadata' filters
add_filter('get_post_metadata', 'myprefix_modify_wppizzaingredients_slices', 100, 3);
function myprefix_modify_wppizzaingredients_slices($metadata, $object_id, $meta_key){

	making sure we are only ever listening to *frontend* ajax requests here 
	(there are other way to do this too, but for simplicities sake...)
	*/

		/* 
		the meta key used in the wppizza add ingredients plugin 
		that determines whether or not half/half and/or quarters was enabled

			/* 
				Option: 
				if you wanted to select a whole category instead - for example category with id 183 - you could use

			*/

				/*
					set the new meta data to return 
					this will in effect force only the "whole" option to be enabled

Widgets/Shortcode

Filters to alter the behaviour of the WPPizza cross-sell display

wppizza_xsells_filter_slick_parameters

The “WPPizza Cross-Sell” extension utilises the “Slick” Carousel to display the cross-sell items. The filter below allows you to alter the settings according to your requirements and the options available

For a full list of available parameters please refer to http://kenwheeler.github.io/slick/

@param: array(parameters)
@return: array(filtered parameters)

example:

add_filter('wppizza_xsells_filter_slick_parameters', 'my_slick_parameters');
function my_slick_parameters($slick_parameters){
	
	/*	
		the following defaults are being set in the plugin by default
					
		$slick_parameters['dots'] = false;
		$slick_parameters['arrows'] = true;
		$slick_parameters['infinite'] = false;
		/* default 3 slides */
		$slick_parameters['slidesToShow'] = 3 ;
		$slick_parameters['slidesToScroll'] = 3 ;
		$slick_parameters['responsive'] = array();
		/* under 800 px browser width, 2 slides only */
		$slick_parameters['responsive'][0]['breakpoint'] = 800;
		$slick_parameters['responsive'][0]['settings'] = array();
		$slick_parameters['responsive'][0]['settings']['slidesToShow'] = 2;
		$slick_parameters['responsive'][0]['settings']['slidesToScroll'] = 2;
		/* under 400 px browser width, 1 slide only */
		$slick_parameters['responsive'][1]['breakpoint'] = 400;
		$slick_parameters['responsive'][1]['settings'] = array();
		$slick_parameters['responsive'][1]['settings']['slidesToShow'] = 1;
		$slick_parameters['responsive'][1]['settings']['slidesToScroll'] = 1;

	*/

	/* example: enabling dots */
	$slick_parameters['dots'] = true;
	
	/* example: enabling infinite loop*/
	$slick_parameters['infinite'] = true;

	/* example: display 4 visible items (instead of the default 3)*/
	$slick_parameters['slidesToShow'] = 4 ;
	$slick_parameters['slidesToScroll'] = 4 ;

	/* example: setting only one breakpoint at 600 with 1 slide only */
	unset($slick_parameters['responsive']);/* first unset default breakpoints */
	$slick_parameters['responsive'][0]['breakpoint'] = 600;
	$slick_parameters['responsive'][0]['settings'] = array();
	$slick_parameters['responsive'][0]['settings']['slidesToShow'] = 1;
	$slick_parameters['responsive'][0]['settings']['slidesToScroll'] = 1;

return $slick_parameters ;
}

wppizza_xsells_filter_shortcode_atts

The Cross-Sells widget is – in essence – displayed by executing the following shortcode: [wppizza single='23,3' price_id='1,0' style='wppizza_xsells' showadditives='0' noheader='1' notags='1'] where “single” and “price_id” will determine which menu items and respective sizes to display. Although the ‘single’ and ‘price_id’ attributes are not filterable, *some* of the other display attributes – such as “currency_main”, “currency_price” , “image_prettyphoto” for example – can be used additionally if you would like to override some display settings. See https://docs.wp-pizza.com/shortcodes/?section=by-category for shortcode attributes

@param: array(default attributes)
@return: array(filtered parameters)

example:

add_filter('wppizza_xsells_filter_shortcode_atts', 'my_shortcode_atts');
function my_shortcode_atts($sc_attributes){
	
	/*	
		the following defaults are being set in the plugin by default
					
		$sc_attributes = array();
		$sc_attributes['style'] = 'wppizza_xsells';//uses set style in xsales plugin settings
		$sc_attributes['showadditives'] = '0';//do not show additives under each item (as they will automatically be displayed combined underneath ifnecessary)
		$sc_attributes['noheader'] = '1';//
		$sc_attributes['notags'] = '1';//only use text from content, stripping all tags/elements 

	*/

	/* example: do not display main currency symbol even though it's is enabled for "normal" menu items in WPPizza->Layout*/
	$sc_attributes['currency_main'] = 0;
	
	/* example: do not display small currency symbol next to the price even though it's is enabled for "normal" menu items in WPPizza->Layout*/
	$sc_attributes['currency_price'] = 0;

	/* example: do NOT strip element tags from content */
	unset($sc_attributes['notags']);

return $sc_attributes;
}

Filters available using WPPizza Google Cloudprint

wppizza_gcp_filter_copies

Sending the second copy of an order to a different printer (id) set in the same google cloudprint account. The Number of copies in the plugin settings WPPizza->Cloudprintmust be set to 2 or more for this to have any effect.

@param: str (printer id)
@param: int (current copy )
@param: int (order id )
@param: array (order formatted )
@param: array (plugin options)
@return: str (printer id)

add_filter('wppizza_gcp_filter_copies', 'myprefix_gpc_set_printerid', 10, 5);
function myprefix_gpc_set_printerid($printer_id, $copy, $order_id, $order_formatted, $gpcOptions){
	/* set a different printer id for the second copy */
	if($copy==2){
		$printer_id = 'some-printer-id-you-need-to set';/* set the printer id here */
	}
return $printer_id;
}

wppizza_gcp_filter_printerid

If you do not need to or want to send multiple copies but simply want to set a dynamic printer id depending on some parameters received, you can try something like this

@param: str (printer id)
@param: int (order id )
@param: array (order formatted )
@param: array (plugin options)
@return: str (printer id)

add_filter('wppizza_gcp_filter_printerid', 'myprefix_gpc_set_printerid', 10, 4);
function myprefix_gpc_set_printerid($printer_id, $order_id, $order_formatted, $gpcOptions){
	/* set a different printer id for the second copy */
	if($order_formatted['some']['key']['selected']=='some value'){
		$printer_id = 'some-printer-id-you-need-to set';/* set the printer id here */
	}
return $printer_id;
}
