Question

我希望能够在我的WooCommerce结帐字段中添加自定义CSS类。我正在使用twitter Bootstrap，我希望能够使用他们的.form-control类。

我查看了form-billing.php中的woocommerce模板文件夹，但我不确定将.form-control类添加到每个文本字段的位置。

以下是form-billing.php

的代码

<?php
/**
 * Checkout billing information form
 *
 * @author      WooThemes
 * @package     WooCommerce/Templates
 * @version     2.1.2
 */

 if ( ! defined( 'ABSPATH' ) ) exit; // Exit if accessed directly
 ?>
 <div class="woocommerce-billing-fields">
<?php if ( WC()->cart->ship_to_billing_address_only() && WC()->cart->needs_shipping() ) : ?>

    <h3><?php _e( 'Billing &amp; Shipping', 'woocommerce' ); ?></h3>

<?php else : ?>

    <h3><?php _e( 'Billing Details', 'woocommerce' ); ?></h3>

<?php endif; ?>

<?php do_action( 'woocommerce_before_checkout_billing_form', $checkout ); ?>

<?php foreach ( $checkout->checkout_fields['billing'] as $key => $field ) : ?>

    <?php woocommerce_form_field( $key, $field, $checkout->get_value( $key ) ); ?>

<?php endforeach; ?>

<?php do_action('woocommerce_after_checkout_billing_form', $checkout ); ?>

<?php if ( ! is_user_logged_in() && $checkout->enable_signup ) : ?>

    <?php if ( $checkout->enable_guest_checkout ) : ?>

        <p class="form-row form-row-wide create-account">
            <input class="input-checkbox" id="createaccount" <?php checked( ( true === $checkout->get_value( 'createaccount' ) || ( true === apply_filters( 'woocommerce_create_account_default_checked', false ) ) ), true) ?> type="checkbox" name="createaccount" value="1" /> <label for="createaccount" class="checkbox"><?php _e( 'Create an account?', 'woocommerce' ); ?></label>
        </p>

    <?php endif; ?>

    <?php do_action( 'woocommerce_before_checkout_registration_form', $checkout ); ?>

    <?php if ( ! empty( $checkout->checkout_fields['account'] ) ) : ?>

        <div class="create-account">

            <p><?php _e( 'Create an account by entering the information below. If you are a returning customer please login at the top of the page.', 'woocommerce' ); ?></p>

            <?php foreach ( $checkout->checkout_fields['account'] as $key => $field ) : ?>

                <?php woocommerce_form_field( $key, $field, $checkout->get_value( $key ) ); ?>

            <?php endforeach; ?>

            <div class="clear"></div>

        </div>

    <?php endif; ?>

    <?php do_action( 'woocommerce_after_checkout_registration_form', $checkout ); ?>

<?php endif; ?>
</div>

我是否需要查看其他模板文件？

Answer 1

icc97的答案几乎就在那里，但是没有用。

我接受了icc97的回答，并对其进行了调试：

add_filter('woocommerce_checkout_fields', 'addBootstrapToCheckoutFields' );
public function addBootstrapToCheckoutFields($fields) {
    foreach ($fields as &$fieldset) {
        foreach ($fieldset as &$field) {
            // if you want to add the form-group class around the label and the input
            $field['class'][] = 'form-group'; 

            // add form-control to the actual input
            $field['input_class'][] = 'form-control';
        }
    }
    return $fields;
}

Answer 2

正如@Peanuts指出的那样，如果我们只想将CSS类添加到某些输入类型呢？

在试验到目前为止发布的解决方案后，（感谢大家！），我想出了一个使用简单“切换案例”的mod，其中逻辑来自/woocommerce/includes/wc-template-functions.php。该函数允许我们一次定位所有输入类型，无论是默认输入类型还是自定义输入类型。

没有必要重写woocommerce_form_field函数来简单地更改输入类型的$defaults args。值得一提的是，该函数还允许我们为字段添加更多css类。

- 所以这是函数 -

/*********************************************************************************************/
/** WooCommerce - Modify each individual input type $args defaults /**
/*********************************************************************************************/

add_filter('woocommerce_form_field_args','wc_form_field_args',10,3);

function wc_form_field_args( $args, $key, $value = null ) {

/*********************************************************************************************/
/** This is not meant to be here, but it serves as a reference
/** of what is possible to be changed. /**

$defaults = array(
    'type'              => 'text',
    'label'             => '',
    'description'       => '',
    'placeholder'       => '',
    'maxlength'         => false,
    'required'          => false,
    'id'                => $key,
    'class'             => array(),
    'label_class'       => array(),
    'input_class'       => array(),
    'return'            => false,
    'options'           => array(),
    'custom_attributes' => array(),
    'validate'          => array(),
    'default'           => '',
);
/*********************************************************************************************/

// Start field type switch case

switch ( $args['type'] ) {

    case "select" :  /* Targets all select input type elements, except the country and state select input types */
        $args['class'][] = 'form-group'; // Add a class to the field's html element wrapper - woocommerce input types (fields) are often wrapped within a <p></p> tag  
        $args['input_class'] = array('form-control', 'input-lg'); // Add a class to the form input itself
        //$args['custom_attributes']['data-plugin'] = 'select2';
        $args['label_class'] = array('control-label');
        $args['custom_attributes'] = array( 'data-plugin' => 'select2', 'data-allow-clear' => 'true', 'aria-hidden' => 'true',  ); // Add custom data attributes to the form input itself
    break;

    case 'country' : /* By default WooCommerce will populate a select with the country names - $args defined for this specific input type targets only the country select element */
        $args['class'][] = 'form-group single-country';
        $args['label_class'] = array('control-label');
    break;

    case "state" : /* By default WooCommerce will populate a select with state names - $args defined for this specific input type targets only the country select element */
        $args['class'][] = 'form-group'; // Add class to the field's html element wrapper 
        $args['input_class'] = array('form-control', 'input-lg'); // add class to the form input itself
        //$args['custom_attributes']['data-plugin'] = 'select2';
        $args['label_class'] = array('control-label');
        $args['custom_attributes'] = array( 'data-plugin' => 'select2', 'data-allow-clear' => 'true', 'aria-hidden' => 'true',  );
    break;


    case "password" :
    case "text" :
    case "email" :
    case "tel" :
    case "number" :
        $args['class'][] = 'form-group';
        //$args['input_class'][] = 'form-control input-lg'; // will return an array of classes, the same as bellow
        $args['input_class'] = array('form-control', 'input-lg');
        $args['label_class'] = array('control-label');
    break;

    case 'textarea' :
        $args['input_class'] = array('form-control', 'input-lg');
        $args['label_class'] = array('control-label');
    break;

    case 'checkbox' :  
    break;

    case 'radio' :
    break;

    default :
        $args['class'][] = 'form-group';
        $args['input_class'] = array('form-control', 'input-lg');
        $args['label_class'] = array('control-label');
    break;
    }

    return $args;
}

上述功能完全解决了同时定位结帐表单输入的问题，这对于结帐表单默认输入类型甚至是自定义新输入类型来说非常简单。似乎不可能打印每个输入类型的html输出，而不创建@abhisek在他的答案中显示的新功能。

加成

该功能似乎也会影响WooCommerce在结帐页面外的功能或模板打印的其他表单字段。我设法通过使用is_page()功能仅在结帐页面上有条件地应用该功能。您的结帐页面可能有不同的slug，因此请更改它以相应地反映它。

如果您只需要为结帐页面应用此功能，请执行以下操作：

评论add_filter（）

//add_filter('woocommerce_form_field_args','wc_form_field_args', 10, 3);

使用add_action代替

add_action('woocommerce_form_field_args', 'wc_form_field_args', 10, 3);

function wc_form_field_args( $args, $key, $value = null ) {

...

// Right after 
    return $args;

// Place the following

if ( !is_page('checkout') ) {
  add_filter('woocommerce_form_field_args','wc_form_field_args', 10, 3);
} else {
  remove_filter('woocommerce_form_field_args','wc_form_field_args', 10, 3);
}


}

之后，该功能只会影响结账页面。

Answer 3

@ Chetan的link and run答案会给你你想要的东西，但一如既往，他们从来都不是很好的答案。

最好的资源是Customizing checkout fields using actions and filters上的WooCommerce Codex页面。

在自定义WooCommerce结帐字段标签和占位符文字＆＃39;在Chetan的页面中，你有以下代码，你需要添加到你的functions.php，我已经修改它，它应该做你想要的，但我没有经过测试代码：

// Hook in
add_filter( 'woocommerce_checkout_fields' , 'my_theme_custom_override_checkout_fields' );

// Our hooked in function - $fields is passed via the filter!
function my_theme_custom_override_checkout_fields( $fields ) {
     foreach ($fields as $fieldset) {
         foreach ($fieldset as $field) {
             $field['class'] = array('form-control');
         }
     }
     return $fields;
}

Answer 4

我通过定义自定义函数来解决问题。逻辑直接取自wc-template-functions.php（我不确定这是否正确，但它确实解决了问题）。

/*
 * Custom form field function for Bootstrap 3
 */
function bootstrap_woocommerce_form_field( $key, $args, $value = null ) {
    $defaults = array(
        'type'              => 'text',
        'label'             => '',
        'placeholder'       => '',
        'maxlength'         => false,
        'required'          => false,
        'class'             => array(),
        'label_class'       => array(),

        'custom_attributes' => array(),
        'validate'          => array(),
