Adding custom checkout fields without plugin

Any ideas anyone? I am looking for the same, I actually purchased that plugin but it breaks with the latest version of Jigoshop. Luckily Jigoshop came up with a new version for the custom checkout fields but they didn’t bother to test it and it doesn’t work ??

add_filter( ‘jigoshop_shipping_fields’, ‘egmont_shipping_fields’ );
add_filter( ‘jigoshop_billing_fields’, ‘egmont_billing_fields’ );

Look in the file jigoshop/classes/jigoshop_checkout.class.php and you can find the two functions:

function get_billing_fields()
function get_shipping_fields()

copy and paste them into your functions.php, rename them, use the filters I listed initally with the new function names … and alter the functions to provide the fields you want.

Easy peasy.

Be advised, the field names have changed in the newly released 1.10 so I use something like this for each field:

return array(
		array(
			'name'          => jigoshop::jigoshop_version() < '1.10' ? 'billing-first_name' : 'billing_first_name',
			'label'         => __('First Name', 'jigoshop'),
			'placeholder'   => __('First Name', 'jigoshop'),
			'required'      => true,
			'class'         => array('form-row-first') ),

This tests for jigoshop version and uses different field names to match version. Most all the field names have changed, so do it for each.

@jeff – please be aware that lexical checking will fail: use version_compare(jigoshop::jigoshop_version(), ‘1.10’, ‘<‘) instead.

This is the right thing way of adding fields. Of course you need to save them by yourself – Jigoshop processes only it’s own fields.
