使用
Text Box / 文本域
woocommerce_form_field("my_textbox", array( 'type' => 'text', 'class' => array('form-row-wide my-textbox'), 'label' => 'Textbox Field', 'placeholder' => 'Placehoder text', 'required' => true, 'default' => '' ), $checkout->get_value( 'my_textbox' ) );
Checkbox / 复选框
woocommerce_form_field("my_textbox", array( 'type' => 'checkbox', 'class' => array('form-row-wide my-checkbox'), 'label' => 'Checkbox Field', 'description' => 'A short description of this checkbox', 'default' => '' ), $checkout->get_value( 'my_textbox' ) );
Textarea / 文本域
woocommerce_form_field("my_textarea", array( 'type' => 'textarea', 'class' => array('form-row-wide my-textarea'), 'label' => 'Textarea Field', 'custom_attributes' => array( 'rows' => 10, 'cols' => 10 ), 'default' => '' ), $checkout->get_value( 'my_textarea' ) );
Select / 下拉列表
woocommerce_form_field("my_select", array( 'type' => 'select', 'class' => array('form-row-wide my-select'), 'label' => 'Dropdown', 'options' => array( '1' => 'Option 1' , '2' => 'Option 2', '3' => 'Option 3' ), ), $checkout->get_value( 'my_select' ) );
Radio / 单选按钮
woocommerce_form_field("my_radio", array( 'type' => 'radio', 'class' => array('form-row-wide my-radio'), 'label' => 'Radio', 'label_class' => 'radio-box', 'options' => array( '1' => 'Option 1' , '2' => 'Option 2', '3' => 'Option 3' ), ), $checkout->get_value( 'my_radio' ) );
Pasword / 密码域
woocommerce_form_field("my_textbox", array( 'type' => 'password', 'class' => array('form-row-wide my-textbox'), 'label' => 'Password', 'placeholder' => '', 'required' => true, 'default' => '' ), $checkout->get_value( 'my_textbox' ) );
控制分栏
通过给"class"参数传递适当的值,可以控制表单字段占全宽还是1/2宽度
form-row-wide: 全宽
form-row-first: 1/2宽度,第一栏
form-row-last:1/2宽度,第二栏
增加清除浮动结构
要在表单字段后输出<div class="clear"></div>
,增加'clear' => true
创建自定义字段之input type=“hidden”
WooCommerce的表单API可以增加自定义字段,例如输出如下结构
<p class="form-row form-row-wide my-hidden-field" id="my_hidden_field_field"> <input type="hidden" class="input-text " name="my_hidden_field" id="my_hidden_field" value=""> </p>
首先创建产生这个结构的处理代码
function wc_form_hidden_field( $field, $key, $args, $value ){ $defaults = array( 'label' => '', 'id' => $key, 'class' => array(), 'input_class' => array(), 'custom_attributes' => array(), 'default' => '', ); $args = wp_parse_args( $args, $defaults ); // Custom attribute handling $custom_attributes = array(); if ( ! empty( $args['custom_attributes'] ) && is_array( $args['custom_attributes'] ) ) foreach ( $args['custom_attributes'] as $attribute => $attribute_value ) $custom_attributes[] = esc_attr( $attribute ) . '="' . esc_attr( $attribute_value ) . '"'; $field = '<p class="form-row ' . esc_attr( implode( ' ', $args['class'] ) ) .'" id="' . esc_attr( $args['id'] ) . '_field">'; $field .= '<input type="hidden" class="input-text ' . esc_attr( implode( ' ', $args['input_class'] ) ) .'" name="' . esc_attr( $key ) . '" id="' . esc_attr( $args['id'] ) . '" value="' . esc_attr( $value ) . '" ' . implode( ' ', $custom_attributes ) . ' /></p>'; return $field; } add_filter( 'woocommerce_form_field_hidden', 'wc_form_hidden_field', 10, 4 );
然后正常调用woocommerce_form_field() 创建隐藏字段,type为hidden
woocommerce_form_field("my_hidden_field", array( 'type' => 'hidden', 'class' => array('form-row-wide my-hidden-field'), 'label' => 'Hidden Field', 'placeholder' => '', 'default' => '' ), $checkout->get_value( 'my_hidden_field' ) );
