Question

我正在为我的网络应用构建审核系统。我是一个完整的初学者，所以我使用重定向而不是ajax。涉及两个页面，post_review页面和process_review页面。以下是post_review页面的代码：

    <?php require_once("../includes/database.php"); 
      session_start();
?>

    <?php
      //mysql_
        $connection = mysqli_connect($dbhost, $dbuser, $dbpass, $dbname);
        if(mysqli_connect_errno())
        {
            die("Database connection failed: " .
                        mysqli_connect_error() .
            " (" . mysqli_connect_errno() . ")");
        }
        $result = "";
        if(isset($_GET['id']))
        {
            $id = (int)$_GET['id'];
            $_SESSION['institute_id'] = $id;
            $query = "SELECT * FROM institutes WHERE institute_id = {$id}";
            $result = mysqli_query($connection, $query);
            $row = mysqli_fetch_assoc($result);
            //echo $row;
            $id = $row["institute_id"];
            $name = $row["name"];
            $tagline = $row["tagline"];
            $city = $row["city"];
            $state = $row["state"];

        }
?>

<form name="review_form" method="post" action="process_review.php">
            <textarea name="review" required="required" cols="60" rows="7" placeholder="Write a review..."></textarea>
            <input type="submit" class="btn btn-custom btn-lg " value="Submit" name="submit_review">
          </form>

process_review.php

的代码

    <?php
    require_once("../includes/database.php");
    session_start();
    $connection = mysqli_connect($dbhost, $dbuser, $dbpass, $dbname);
    if(mysqli_connect_errno())
    {
        die("Database connection failed: " .
                    mysqli_connect_error() .
        " (" . mysqli_connect_errno() . ")");
    }
        if(isset($_POST['submit_review'])) 
        {
            $review = mysqli_real_escape_string($connection, $_POST['review']);
            $student_id = $_SESSION['student_id'];
            $institute_id = $_SESSION['institute_id'];
                echo $institute_id;
                echo $student_id;
            $review_query = "INSERT INTO reviews 
                            (content, student_id, institute_id) 
                            VALUES ($review, $student_id, $institute_id)";
            $result = mysqli_query($connection, $review_query);
            if(!$result){
        die("Database query failed.". mysqli_error($connection));
    }else{
        header('Location: institute_profile_test.php?id=' . $institute_id);
        }     
    }
 ?>

用户登录时已设置

$_SESSION['student_id']。

我面临的问题是当我点击提交时，我会被重定向到process_review.php，我发现此错误消息：

解析错误：语法错误，第22行的D：\ xampp \ htdocs \ edhoc \ public \ process_review.php中的意外“{”

PS：我知道这可能是一个微不足道的问题，但我的项目将在4个小时后完成，我很绝望。
