wc_countries-状态选择下拉列表-woocommerce [英] wc_countries - states selection dropdown - woocommerce

问题描述

我正在努力用默认的WooCommerce国家/地区设置表单，并说明选择下拉列表.

I am struggling to set up a form with a default WooCommerce country and states selection dropdowns.

基本上，我想显示国家选择"，然后根据国家选择显示状态选择.因此，如果用户选择英国，则会显示带有州选择的新下拉列表.

Basically, I want to show Country selection and then state selection based on the country selection. So if the user chooses UK, the new dropdown with states selection will show.

我了解到了:

<?php
global $woocommerce;
$countries_obj   = new WC_Countries();
$countries   = $countries_obj->__get('countries');
$default_country = $countries_obj->get_base_country();
$default_county_states = $countries_obj->get_states( $default_country );

echo '<div id="ships_from_countries_field">' . __('Countries') . '';

    woocommerce_form_field('my_country_field', array(
           'type'       => 'select',
           'class'      => array( 'chzn-drop' ),
           'label'      => __('Item ships from - country'),
           'placeholder'    => __('Select a Country'),
           'options'    => $countries
            )
     );
 echo '</div>';

 echo '<div id="ships_from_state_field">' . __('States') . '';

     woocommerce_form_field('my_state_field', array(
            'type'       => 'select',
            'class'      => array( 'chzn-drop' ),
            'label'      => __('Item ships from - state'),
            'placeholder'    => __('Select a State'),
            'options'    => $default_county_states
             )
      );
  echo '</div>';
  ?>

国家/地区"下拉列表显示国家/地区和国家/地区下拉列表，显示商店基地的状态-英国

Countries dropdown is displaying countries and states dropdown displaying states of the shop base - UK

但是如何使它们协同工作并保存值?

But how do I make them work together and save the values?

找不到任何信息，有人有做这项工作的经验吗?

Cannot find any info, anybody has any experience making this work?

推荐答案

首先，有一个国家和州的类型..您不需要做很多事情...就像这样...

first of, there's a type for country and state.. you don't need to do much... it's just like this...

echo '<div id="ships_from_countries_field">' . __('Countries') . '';

    woocommerce_form_field('my_country_field', array(
       'type'       => 'country',
       'class'      => array( 'chzn-drop' ),
       'label'      => __('Item ships from - country'),
       'placeholder'    => __('Select a Country')
        )
    );
echo '</div>';

echo '<div id="ships_from_state_field">' . __('States') . '';

    woocommerce_form_field('my_state_field', array(
        'type'       => 'state',
        'class'      => array( 'chzn-drop' ),
        'label'      => __('Item ships from - state'),
        'placeholder'    => __('Select a State')
        )
    );
echo '</div>';

记下它们的类型...它们不是select类型.

take note of their type... they're not of type select.

现在解决您的问题.

PHP

您需要具有针对国家和州的本地化脚本...我不会继续使用 wp_localize_script() .如果需要，请阅读链接.这是其中的一部分.

you need to have localized script for country and state... I won't go on how to use wp_localize_script(). Read the link if you need to. Here's a part of it.

$wc_country = array(
    'country' => json_encode( array_merge( WC()->countries->get_allowed_country_states(), WC()->countries->get_shipping_country_states() ) )
);
wp_localize_script( 'my-js', 'my_js', $wc_country );

javascript

这样，在您的my-js脚本(脚本文件)中，您可以读取如下状态:

with that, in your my-js script (a script file) you can read the state like this:

    var states_json = my_js.countries.replace( /"/g, '"' ),
        states = $.parseJSON( states_json );

然后您必须在您所在的国家/地区添加更改事件，然后根据所选国家/地区重新填充州/省...

you then have to add a change event on your country and repopulate state based on what country was selected...

示例:states["PH"]如果所选国家是菲律宾

example: states["PH"] if country selected is Philippines

00: "Metro Manila"
ABR: "Abra"
AGN: "Agusan del Norte"
AGS: "Agusan del Sur"
AKL: "Aklan"
ALB: "Albay"
ANT: "Antique"
APA: "Apayao"
AUR: "Aurora"
BAN: "Bataan"
BAS: "Basilan"
BEN: "Benguet"
BIL: "Biliran"
.....
WSA: "Samar"
ZAN: "Zamboanga del Norte"
ZAS: "Zamboanga del Sur"
ZMB: "Zambales"
ZSI: "Zamboanga Sibugay"

然后您可以使用jQuery构建这样的选项.

you can then build your options like this using jQuery..

var options = '',
    state = states[ country ]; // country can be: var country = $('country').val();

for( var index in state ) {
    if ( state.hasOwnProperty( index ) ) {
        options = options + '<option value="' + index + '">' + state[ index ] + '</option>';
    }
}
