我正在尝试为我的网站自定义注册表格.我一直在使用本指南,并已成功为我的注册表创建/存储了其他字段. Guide to customized Registration.
我在注册表格中创建了一个下拉/选择字段,供用户选择在注册时是标准帐户还是教育帐户类型：
如果他们选择教育帐户类型,我希望出现其他字段,以便我可以收集他们学校的其他数据.我是否可以根据表单中另一个字段的当前值提供条件逻辑来确定某个字段是否可见？
这是我要完成的工作的一个示例：
有人可以指出我正确的方向来完成条件表单字段吗？另外,我不想为此使用第三方插件.为此,完全控制很重要.
编辑：
根据要求,这是我的功能的完整代码：

解决方法:
显示隐藏字段的唯一方法是使用Javascript / jQuery,因为这是客户端事件.
因此,我对您的代码做了一些小的更改,添加了必要的jQuery,以处理根据account_type select字段实时事件选择显示和隐藏school_name文本字段.
这是我在您的代码中更改的两个函数：
// Get custom fields
if(!function_exists('get_custom_fields')){
function get_custom_fields(){
return apply_filters('custom_fields', array(
'verified_education_acct' => array(
'type' => 'checkbox',
'label' => __('Verified?'),
'required' => false,
'hide_in_account' => true,
'hide_in_admin' => false,
'hide_in_registration' => true,
'hide_in_checkout' => true
),
'customer_id_num' => array(
'type' => 'text',
'label' => __('Customer ID# (Acumatica)'),
'placeholder' => __('e.g. 1234567890'),
'required' => false,
'hide_in_account' => true,
'hide_in_admin' => false,
'hide_in_checkout' => true,
'hide_in_registration' => true
),
'account_type' => array(
'type' => 'select',
'label' => __('What type of account will this be?'),
'class' => array('form-row-wide'),
'options' => array(
'' => __('Select an option...'),
1 => __('Education'),
2 => __('Standard')
),
'required' => true,
'hide_in_account' => true,
'hide_in_admin' => false,
'hide_in_checkout' => false,
'hide_in_registration' => false,
'js_trigger' => true, // <=== <=== Enabling Javascript
),
'school_name' => array(
'type' => 'text',
'label' => __('School Name'),
'class' => array('form-row-wide off'), // <=== <=== Hidden field
'placeholder' => __('e.g. North Middle School'),
'required' => true,
'hide_in_account' => false,
'hide_in_admin' => false,
'hide_in_checkout' => false,
'hide_in_registration' => false,
'js_triggered_by' => 'account_type', // <=== JS: field that trigger show/hide
'js_show_val' => '1', // <=== <=== JS: selected field value that show this field
),
));
}
}
//Add them to User Area
if(!function_exists('print_user_frontend_fields')){
function print_user_frontend_fields(){
$fields = get_custom_fields();
$user_logged_in = is_user_logged_in();
$enable_js = false; // Initializing
$data_js = []; // Initializing
// Hiding conditional field (with "off" class)
echo '<style>p.form-row.off{display:none;}</style>';
foreach ($fields as $key => $field_args) {
if($user_logged_in && !empty($field_args['hide_in_account'])){
continue;
}
if(! $user_logged_in && ! empty($field_args['hide_in_registration'])){
continue;
}
if( isset($field_args['js_trigger']) && $field_args['js_trigger'] ){
$enable_js = true;
}
if( isset($field_args['js_triggered_by']) && $field_args['js_show_val'] ){
$data_js[$key] = [ $field_args['js_triggered_by'] => $field_args['js_show_val'] ];
}
// Form fields output
woocommerce_form_field($key, $field_args);
}
if( $user_logged_in || ! $enable_js ) return; // Exit
// JQuery code
?>
<script type="text/javascript">
jQuery( function($){
var a = <?php echo json_encode($data_js) ?>;
$.each(a, function(b,o){
$.each(o, function(k,v){
$('#'+k).on('change', function(){
var cf = '#'+b+'_field';
if ( $(this).val() == v && $(cf).hasClass('off') ) {
$(cf).removeClass('off');
} else if ( $(this).val() != v && ! $(cf).hasClass('off') ) {
$(cf).addClass('off');
}
});
});
});
});
</script>
<?php
}
}
代码进入您的活动子主题(或活动主题)的function.php文件中.经过测试和工作.
1)加载时,字段被隐藏.
2)在选择“教育”时,将显示该字段.
3)在选择“标准”(或什么都不选)时,该字段被隐藏.
to handle multiple fields you will need to make some changes, as this example is for one field.
