我有user-edit.php的代码我需要这个代码是从数据库中获取用户数据并将其显示到文本框以及用户能够编辑文本框值和更新数据库

<?php
    include("config/session.php");
    include("config/connection.php");
    $user_id =  $_SESSION['LOGGED_USER_ID']; 
?>

<?php 
    $sql_query = "SELECT * FROM table_users WHERE `SNo` = '$user_id'"; 
    $query = mysql_query($sql_query);
    //$i = 1;
    $fetch = mysql_fetch_assoc($query);

    //$user_id = $_GET['id'];   

?>      
<form name="form1" action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST" >
    <fieldset>

        <p>
            <label for="simple-input" >User Name</label>
            <input type="text" id="UserName" class="round default-width-input" autofocus name="UserName" value="<?php echo $fetch['UserName'];?>" readonly="readonly" />
        </p>
        <p>
            <label for="simple-input" >Password</label>
            <input type="text" id="pass_word" class="round default-width-input" autofocus name="pass_word" value="<?php echo $fetch['pass_word'];?>" />
        </p>
        <p>
            <label for="simple-input" >Email ID</label>

        </p>
        <p>

    <input type="submit" class="btn btn-primary btn-large" name="form_submit" value="Update Data"/> 

</form>

<?php

if(isset($_POST['form_submit']))
{
    "UPDATE `table_users` SET `pass_word` =  '".$_POST['pass_word']."',`Email` =  '".$_POST['Email']."',`website` =  '".$_POST['website']."', WHERE `SNo` = '$user_id'";

    // sql query for update data into database
    if(mysql_query($sql_query))
     {

      echo '<script type="text/javascript">';
      echo 'alert("Data Are Updated Successfully");';
      echo '</script>';

     }
     else
     {

      echo '<script type="text/javascript">';
      echo 'alert("error occured while updating data");';
      echo '</script>';
    }
    }
?>

        </div>
    </div>                          
</div>

一直在用这个工作几个小时仍然没有更新到mysql数据库的数据，尝试了几种方法但是文本框值仍然无法更新数据库，请帮忙

在,

之前移除where in query

$sql_query="UPDATE `table_users` SET `pass_word` =  '".$_POST['pass_word']."',`Email` =  '".$_POST['Email']."',`website` =  '".$_POST['website']."' WHERE `SNo` = '$user_id'";

在$sql_query中存储查询，因为您没有存储update string into variable 在$sql_query中没有商店，您运行sql query

if(mysql_query($sql_query))所以存储update query in $sql_query

从数据库中获取数据并且更新无效
