Php 在wordpress数据库中插入单引号和双引号

我正在尝试将一些标题保存到wordpress中的mysql数据库，允许双引号和单引号。因此，我希望能够插入字符串，例如：

    A man's dog walked into the bar
    The "main reason" it does not work
    It's time to announce "The Show" in an hour

我的代码如下所示：

    $question_id = filter_var($_REQUEST['question_id'], FILTER_SANITIZE_NUMBER_INT);
    $feedback_correct = preg_replace("/[^a-zA-Z0-9'\"?_\. !&-]+/","",sanitize_text_field($_REQUEST['feedback_correct']));
    $feedback_incorrect = preg_replace("/[^a-zA-Z0-9'\"?_\. !&-]+/","",sanitize_text_field($_REQUEST['feedback_incorrect']));
    //preg_replace is to strip out any characters we dont want in the title like "<>|}{[]/"
    $data = array(
    'feedback_correct' => $feedback_correct,
    'feedback_incorrect' => $feedback_incorrect
    );

    $update_feedback = $eot_quiz->updateQuestion($data, $question_id);

访问数据库后，我的字符串如下所示：

    A man

*字符串在单引号后被截断

    The "main reason" it does not work

*用双引号表示ok

    It

*字符串在单引号后被截断

如何在数据库中正确插入这些字符串？提前谢谢

     <?php
      $quiz_question = $eot_quiz->get_question_by_id($question_id);

      ?>
       <div class="bs">

       </div>
    </div>

正确答案的反馈
在元素属性中需要某些内容时，可以使用
esc\u attr
：

<input type="text" class="form-control" name="feedback_correct" placeholder="Correct Feedback" value='<?php
//Always escape before echoing to an html attribute
esc_attr($quiz_question['feedback_correct']);
?>'>

什么是
$wpdb
的基类？找出它的逃逸机制并使用它

或者，使用
addslashes（）

请不要尝试使用
preg\u replace
，您可能无法处理所有需要转义的字符。（不仅仅是撇号和引号。）
不，这里没有bobby表格。
wpdb
代码使用了正确的绑定参数。我尝试了bobby tables:$result=$wpdb->update（TABLE\u quick\u QUESTION，$data，array（'ID'=>$ID），array（'%s'，'%s'）；同样的结果可以解释
preg\u replace（）
方法调用的目的。请回答您的问题。@O.Jones
