5.16.Checkout Formfields

Modify the customer form fields available on the checkout page

A few examples as to how you can show/hide/add/modify input formfields available on the checkout page

Simple show/hide formfields using css selectors

If you wish to simply show hide some formfields when an order is set to be a pickup order.
See here , for options as to where to add this css

example:

/**********************************************************
	target specific elements on pickup
	use your browsers element inspector to ascertain the exact classname you need to target
**********************************************************/
.wppizza-order-ispickup .wppizza-personal-details > .wppizza-cname{display:none}
.wppizza-order-ispickup .wppizza-personal-details > .wppizza-caddress{display:none}
/* etc etc */

Make sure to not hide things that you have also set to be “required” (unless they are already prefilled in some way) or the customer will never be able to check out …

wppizza_register_formfields

Add / modify a formfield on the checkout page. First of all, you can of course already add/remove and conditionally set various formfield properties by going to WPPizza ->Order Form. If you however need some more granular control or simply add your own, see the examples below

.

example:

/*************************************************** 
	add the filter and corresponding function
****************************************************/
add_filter('wppizza_register_formfields', 'my_prefix_modify_wppizza_formfields');
function my_prefix_modify_wppizza_formfields($formfields){

	/* 
		*unique* identifier for the formfield you want to add
		if you add more than one, each one must be a unique id
		for simplicity and demonstration purposes the some is being used here for all !

		if you wish ta alter an already existing formfield use that formfields key instead 
		a print_r($formfields) will show you all registered formfields and their keys if you need to identify a particular one 

	*/

Pre-filling form fields

If a formfield is set to have ‘onregister’ and ‘prefill’ set to true, the relevant value will be prefilled/selected when a user logs in, if you want to or need to (especially with hidden fields) always pre-set a specific value I’d suggest something like the below

example:

add_action('init', 'myprefix_prefill_formfields');
function myprefix_prefill_formfields(){

	/*
	prefill a value if it has not ever been set
	*unique* identifier for the formfield you want to prefill 
	*/
	$unique_ident = 'my_unique_formfield_id';

	if(!isset($_SESSION[WPPIZZA_SLUG.'_userdata'][$unique_ident])){
		
		/* text / hidden formfields */
		$_SESSION[WPPIZZA_SLUG.'_userdata'][$unique_ident] = 'some input value';
		
		/* radios - one of the values as defined in 'value' array of the registered formfield*/
		$_SESSION[WPPIZZA_SLUG.'_userdata'][$unique_ident] = '2nd value';

		/* checkbox (single) - boolean */
		$_SESSION[WPPIZZA_SLUG.'_userdata'][$unique_ident] = true; //bool

		/* checkbox (multiple)  - one or more of the values as defined in 'value' array ofthe  registered formfield*/
		$_SESSION[WPPIZZA_SLUG.'_userdata'][$unique_ident] = array('1st value','3rd value') ; //array
	}
	
return;
}
