我想在checkout表单字段中添加bootstrap form-control
类。根据woocommerce文件
function custom_override_checkout_fields( $fields ) {
$fields['order']['order_comments']['placeholder'] = 'My new placeholder';
$fields['order']['order_comments']['label'] = 'My new label';
return $fields;
}
Each field contains an array of properties:
type – type of field (text, textarea, password, select)
label – label for the input field
placeholder – placeholder for the input
class – class for the input
required – true or false, whether or not the field is require
clear – true or false, applies a clear fix to the field/label
label_class – class for the label element
options – for select boxes, array of options (key => value pairs)
技术上如此
$fields['order']['order_comments']['class'] = 'form-control';
应该有效,但我收到警告
implode(): Invalid arguments passed
并且该类未被应用。我做错了什么?
答案 0 :(得分:1)
explode()
函数需要一个数组,因为结帐字段class
属性使用数组。
现在,对于需要在字段本身上的bootstrap form-control
类,您将使用未记录的 'input_class'
属性一个数组这样:
$fields['order']['order_comments']['input_class'] = array('form-control');
它会像你期望的那样正常工作(经过测试和运作)。
对于'class'
属性,Woocommerce使用以下类:
form-row-first
(左半场)form-row-last
(右侧半场)form-row-wide
(全字段)
