javascript - post方法不发送全文

Question

我有一个存储过程可以同时向数据库发送和获取博客数据:

CREATE DEFINER=`root`@`localhost` PROCEDURE `post_and_fetch_ans`(
    IN answerbody longtext,
    IN postid int,
    IN answerer int)
BEGIN
   INSERT INTO `login`.`answers` (answer_body,userpost_post_id,users_user_id) VALUES (answerbody,postid,answerer);
   SELECT * FROM `login`.`answers` WHERE userpost_post_id = postid  ORDER BY answer_date DESC LIMIT 1;
END

但我的问题是我在文本编辑器上写的文本数据量，只有几行被发送并存储到数据库。我正在使用 ajax 将数据发送到 php 页面，该页面将其存储到数据库。

$('#answerform').submit(function(event){
   event.preventDefault();
   var data='answer_body='+CKEDITOR.instances.content.getData()+'&userpost_post_id=<?php echo $contents[0]->post_id;?>&users_user_id=<?php echo $userdata->user_id; ?>';
   alert(data);

   $.ajax('../includes/verifyanswer.php',{
        data:data,
        type:"POST",
        datatype:'json',
        success:function(response){
            alert(response);

            var obj=$.parseJSON(response);

            $('#mainanswer').hide();
            $('#answerform').hide();
            $('#answerthisquestion').show();
            var str="<div class='styleanswer' >"+obj[0]['answer_body']+'</div><hr>';

            $('#answerwrapper').append(str);
            $('#answerwrapper pre code').each(function(i, block) {
                hljs.highlightBlock(block);
            });
        },
        error:function(response){
            alert(response);
        }
    });
}); 

verifyanswer.php 页面是:

require_once '../core/init.php';
$answer=$_POST['answer_body'];

$post_id=$_POST['userpost_post_id'];
$answerer=$_POST['users_user_id'];

if(isset($answer,$post_id,$answerer)){
    if(!empty($answer) && !empty($post_id) && !empty($answerer)){
        $db = DB::getInstance();
        $result = $db->post_and_fetch("CALL login.post_and_fetch_ans(?,?,?)",array($answer,$post_id,$answerer))->result();
        echo json_encode($result);
    }
}

这条线

$answer=$_POST['answer_body'];

仅包含部分(比实际文本少得多)文本，而不是完整文本。因此数据库中存储的文本较少

问题的一个例子是

我将这段文本发送到数据库中存储

但我只得到存储在数据库中的这几行文本

想到的选项很少。

1. 撇号可能会结束您的 SQL 语句。您将需要对其进行转义。

2. 您尝试存储数据的字段太小。
