我正在创建具有评论系统的社交媒体网站，其中用户编写的文本将发布在板上并存储在数据库中，但问题是没有显示文本，也没有文本存储在数据库中，但旁边的其他字段文本已存储，因此任何人都可以帮助我？？？
配置文件.php
<?php
ob_start();
session_start();
require_once('for members/scripts/global.php');
if($_SESSION['login'] != 'true'){
header("location:index.php");
}
$user_id = $_SESSION['user_id'];
$send =(isset($_POST['send']));
$writenCom = (isset($_POST['post']));
if($send && $writenCom){
echo $writenCom;
$query = mysql_query("INSERT INTO comment(sender_id, text, comment_date)VALUES('$user_id', '$writenCom', now())")or die(mysql_error());
while($row = mysql_fetch_array($query)){
echo"comment success";
}
}
?>
