问题是单选按钮没有保存。为此，我在下面附上了一段视频。单选按钮未保存 → https://www.screencast.com/t/pLad8AwrOXiS

Please guide me where I am going wrong. Is isset missing for this radio button? If yes, then help me finish that.

试试这个代码。它的工作。

            <p> <input type="radio" class="what_to_check_for" <?php  checked($what_to_check_for ,'check_for_counter'); ?> id="<?php echo $this->get_field_id( 'check_for_counter' ); ?>" value="check_for_counter" name="<?php echo $this->get_field_name( 'what_to_check_for' ); ?>" >
            <label for="<?php echo $this->get_field_id( 'check_for_counter' ); ?>">Check whether to display description or not</label> </p>

            <p> <input type="radio" class="what_to_check_for" <?php checked($what_to_check_for ,'check_for_image'); ?> id="<?php echo $this->get_field_id( 'check_for_image' ); ?>" value="check_for_image" name="<?php echo $this->get_field_name( 'what_to_check_for' ); ?>" >
            <label for="<?php echo $this->get_field_id( 'check_for_image' ); ?>">Select to Post with Thumbnails</label> </p>
