Question

By selecting search item and click on find tour i want to search particular categories but in print_r($_GET) i received on only one category id

I want all four category id in $_GET variable to search for categories

我正在使用此代码进行下拉： -

            $category = array(
                'show_option_all'    => 'Select Tour',
                'orderby'            => 'name',
                'show_count'         => 0,
                'taxonomy'           => 'tour_category',
            ); 
            $tour_category = wp_dropdown_categories($category);
            $line = array(
                'show_option_all'    => 'Select cruise Line',
                'orderby'            => 'name',
                'echo'               => 1,
                'taxonomy'           => 'genre',
            ); 
            $cruise_line = wp_dropdown_categories($line);
            $month = array(
                'show_option_all'    => 'Select Month',
                'orderby'            => 'name',
                'echo'               => 1,
                'taxonomy'           => 'date_month',
            ); 
            $date_month = wp_dropdown_categories($month);
            $length = array(
                'show_option_all'    => 'Select Trip Length',
                'orderby'            => 'name',
                'echo'               => 1,
                'taxonomy'           => 'writer',
            ); 
            $trip_length = wp_dropdown_categories($length);

实际上我想根据这四个类别进行搜索。我以前的代码是： -

$text_field_label = _x( 'Search Tour', 'placeholder', 'adventure-tours' );



            printf(

                '<div class="%s">%s' . 

                    '<div class="form-block__item form-block__field-width-icon">' .

                        '<input type="text" %svalue="%s" name="s"><i class="td-search-1"></i>' .

                    '</div>' .

                '</div>',

                esc_attr( 'col-sm-' . $search_field_cells ),

                $is_show_label ? sprintf( '<div class="form-block__item-label 1">%s</div>', esc_html( $text_field_label ) ) : '',

                $is_show_label ? '' : sprintf( 'placeholder="%s" ', esc_attr( $text_field_label ) ),

                get_search_query()

            );

我在下拉列表中将其转换为四个不同的类别。

Answer 1

尝试这样的事情

$query  = explode('&', $_SERVER['QUERY_STRING']);
$param = array();

foreach( $query as $str)
{
  list($name, $value) = explode('=', $str, 2);
  $param[urldecode($name)][] = urldecode($value);
}
print_r($param);

Answer 2

我在这里注意到的第一件事是你对所有四个选择框使用相同的名称。

因为如果你没有在name函数的参数中添加wp_dropdown_categories属性，那么它将自动使用默认名称，即cat。

因此，为每个选择框添加不同的name属性，以便在提交表单时，您将在GET查询字符串中有四个不同的选择变量，如下所示：

$category = array(
                'show_option_all'    => 'Select Tour',
                'orderby'            => 'name',
                'show_count'         => 0,
                'name'               => 'cat-tour',
                'taxonomy'           => 'tour_category',
            ); 
            $tour_category = wp_dropdown_categories($category);
            $line = array(
                'show_option_all'    => 'Select cruise Line',
                'orderby'            => 'name',
                'echo'               => 1,
                'name'               => 'cat-genre',
                'taxonomy'           => 'genre',
            ); 
            $cruise_line = wp_dropdown_categories($line);
            $month = array(
                'show_option_all'    => 'Select Month',
                'orderby'            => 'name',
                'echo'               => 1,
                'name'               => 'cat-date',
                'taxonomy'           => 'date_month',
            ); 
            $date_month = wp_dropdown_categories($month);
            $length = array(
                'show_option_all'    => 'Select Trip Length',
                'orderby'            => 'name',
                'echo'               => 1,
                'name'               => 'cat-writer',
                'taxonomy'           => 'writer',
            ); 
            $trip_length = wp_dropdown_categories($length);

希望它有所帮助。
