我正在自定义WooCommerce结帐页面字段。我想在字段之间添加一个标题（文本）。我已经像这样重新排序了字段
add_filter('woocommerce_checkout_fields', 'ac_checkout_reorder_fields');
function ac_checkout_reorder_fields($fields) {
$order = array(
"billing_first_name",
"billing_last_name",
"billing_company",
"billing_email",
"billing_phone",
"billing_address_1",
"billing_address_2",
"billing_postcode",
"billing_country"
);
foreach($order as $field)
{
$ordered_fields[$field] = $fields["billing"][$field];
}
$fields["billing"] = $ordered_fields;
return $fields;
}
然后我添加了这样的新标题
add_action( 'woocommerce_after_checkout_billing_form', 'add_custom_heading' );
function add_custom_heading( $checkout ) {
echo '<div id="add_custom_heading"><h2>' . __('Custom Heading Here') . '</h2></div>' ;
}
现在，字段已重新排列，并显示自定义标题。但我希望标题显示在名称和公司字段的正下方。使用我的代码，该字段被添加到下面。我如何将其重新定位在我想要的位置。
PS：我还尝试使用此钩子添加自定义整个字段的部分，woocommerce_checkout_fields添加占位符并删除标签。这是代码，但这也不能帮助我解决问题。
function add_wc_custom_fields($fields) {
global $woocommerce;
$countries_obj = new WC_Countries();
$countries = $countries_obj->__get('countries');
$fields['billing']['billing_first_name'] = array(
'label' => '',
'placeholder' => _x('First Name*', 'placeholder', 'woocommerce'),
'required' => true,
'class' => array( 'form-row-first' ),
);
$fields['billing']['billing_last_name'] = array(
'label' => '',
'placeholder' => _x('last Name*', 'placeholder', 'woocommerce'),
'required' => true,
'class' => array( 'form-row-last' ),
);
$fields['billing']['billing_company'] = array(
'label' => '',
'placeholder' => _x('Company Name', 'placeholder', 'woocommerce'),
'required' => false,
'class' => array('checkout-billing-company')
);
$fields['billing']['billing_address_1'] = array(
'label' => '',
'placeholder' => _x('Address(Line 1)*', 'placeholder', 'woocommerce'),
'required' => true,
'class' => array('checkout-billing-addressL1')
);
$fields['billing']['billing_address_2'] = array(
'label' => '',
'placeholder' => _x('Address(Line 2)*', 'placeholder', 'woocommerce'),
'required' => false,
'class' => array('checkout-billing-addressL2')
);
$fields['billing']['billing_email'] = array(
'label' => '',
'placeholder' => _x('Email Address*', 'placeholder', 'woocommerce'),
'required' => true,
'class' => array('form-row-first')
);
$fields['billing']['billing_phone'] = array(
'label' => '',
'placeholder' => _x('Phone Number', 'placeholder', 'woocommerce'),
'required' => false,
'class' => array('form-row-last')
);
$fields['billing']['billing_city'] = array(
'label' => '',
'placeholder' => _x('Town/City', 'placeholder', 'woocommerce'),
'required' => false,
'class' => array('form-row-first')
);
$fields['billing']['billing_state'] = array(
'label' => '',
'placeholder' => _x('State/County', 'placeholder', 'woocommerce'),
'required' => false,
'class' => array('form-row-first')
);
$fields['billing']['billing_postcode'] = array(
'label' => '',
'placeholder' => _x('Zip/Postcode', 'placeholder', 'woocommerce'),
'required' => false,
'class' => array('form-row-first')
);
$fields['billing']['billing_country'] = array(
'label' => '',
'type' => 'select',
'placeholder' => _x('Country', 'placeholder', 'woocommerce'),
'required' => false,
'class' => array('form-row-last'),
'options' => $countries
);
return $fields;
}
add_filter('woocommerce_checkout_fields', 'add_wc_custom_fields');
我们可以使用过滤器'woocommerce_form_field_' . $type...其中$type是输入的类型...在我们的例子中billing_company是文本类型...此过滤器返回字段的 html，在我们的案例计费字段中，billing_company ..过滤器传递了 4 个参数，分别是 $field 、$key、$args、$value ...我们只需要其中两个...
add_action( 'woocommerce_form_field_text','reigel_custom_heading', 10, 2 );
function reigel_custom_heading( $field, $key ){
// will only execute if the field is billing_company and we are on the checkout page...
if ( is_checkout() && ( $key == 'billing_company') ) {
$field .= '<p class="form-row form-row-wide">Custom Heading</p>';
}
return $field;
}
重要提示：如果我们不将其格式化为带有类form-row的段落，则Woocommerce将其置于所有计费字段的顶部（我不知道原因）。这向我们表明，这是"黑客"，也许你的目标以不同的方式实现得更好。
与其挂钩到现有的woocommerce_form_field_<field_type>过滤器（如 woocommerce_form_field_text），我更喜欢使用 woocommerce_form_field_<field_type> 过滤器来创建新的字段类型。这允许我们为其他字段类型添加 HTML 输出（因此我们可以将 HTML 输出用于标题），并且在使用 woocommerce_checkout_fields 过滤器修改结帐字段时，我们可以使用此新标题"字段类型"。
// Add field type to WooCommerce form field
add_filter( 'woocommerce_form_field_heading','sc_woocommerce_form_field_heading', 10, 4 );
function sc_woocommerce_form_field_heading($field, $key, $args, $value) {
$output = '<h3 class="form-row form-row-wide">'.__( $args['label'], 'woocommerce' ).'</h3>';
echo $output;
}
// Modify checkout fields
add_filter( 'woocommerce_checkout_fields','custom_override_checkout_fields' );
function custom_override_checkout_fields( $fields ) {
$fields['billing']['billing_heading_name'] = array(
'type' => 'heading',
'label' => 'Heading here',
);
使用上述方法，原始问题的解决方案将是：
add_filter('woocommerce_checkout_fields', 'ac_checkout_reorder_fields');
function ac_checkout_reorder_fields($fields) {
$fields['billing']['billing_heading_name'] = array(
'type' => 'heading',
'label' => 'Heading here',
);
$order = array(
"billing_first_name",
"billing_last_name",
"billing_heading_name",
"billing_company",
"billing_email",
"billing_phone",
"billing_address_1",
"billing_address_2",
"billing_postcode",
"billing_country"
);
foreach($order as $field) {
$ordered_fields[$field] = $fields["billing"][$field];
}
$fields["billing"] = $ordered_fields;
return $fields;
}
add_filter('woocommerce_form_field', 'addHeadingsInBetweenFormFields', 10, 4);
function addHeadingsInBetweenFormFields($field, $key, $args, $value = null) {
if (is_checkout() & $key === 'billing_first_name') {
$a = '<p class="form-row form-row-wide">Shipping</p>';
return $a . $field;
}
return $field;
}
