自定義驗證聯系表格7

Question

我需要驗證表格 - 如果有人輸入電話號碼 / email 則不再需要 email / 電話號碼。 我試過了

(function($) {
    $(document).ready(function(){
        $(".wpcf7-email").on('change', function postinput(){
            var id = $(this).val();
            if(id) {
                   document.getElementById('phone').setAttribute("aria-required", "false");
                   $( "#phone" ).removeClass( "wpcf7-validates-as-required" )
           } else {
                   document.getElementById('phone').setAttribute("aria-required", "true");
           }
        });
    }); 
})(jQuery);

並嘗試了 PHP

    add_filter( 'wpcf7_validate_text', 'xyz_validation', 20, 2 );

    function xyz_validation( $result, $tag ) {

        $email = isset( $_POST['email'] ) ? trim( $_POST['email'] ) : '';
        $phone = isset( $_POST['phone'] ) ? trim( $_POST['phone'] ) : '';

        if ( !empty($email) && !empty($subject) ) {
          $result->invalidate( $tag, "Really?" );
        }

我的聯系表格（jquery - 在 PHP 表格中不需要（沒有符號'*'）

[email* email id:email]
[number* phone id:phone]

在不使用 javascript 的情況下，實現此目的的一種方法是使用 CF7 的智能電網布局擴展，它旨在彌補 CF7 插件的許多缺點。 它引入了一個自定義驗證鈎子，允許根據整個提交的數據集驗證提交，

add_filter( 'cf7sg_validate_submission','validate_field_submission',10,3);
function validate_field_submission($validation_errors, $submission, $cf7_key){
  if('my-contact-form'==$cf7_key ){ //check this is the right form.
    //$validation_errors is an array of field-names=>error messages.
    //these include the simple validation exposed in the CF7 plugin for required fields/special field formats.
    if(!empty($submission['phone']) && wpcf7_get_message( 'invalid_required' ) == $validation_errors['email']){
      //reset the error message.
      $validation_errors['email'] = '';
    }
    if(!empty($submission['email']) && wpcf7_get_message( 'invalid_required' ) == $validation_errors['phone']){
      //reset the error message.
      $validation_errors['phone'] = '';
    }
  return $validation_errors;
  }    
}
