【问题描述】：

我收到了这个错误

Parse error: syntax error, unexpected '' in C:\wamp\www\widget_corp\public
\create_subject.php on line 24

当我点击“Creae Subject”按钮时。

我整天都在尝试修复它，但真的找不到问题所在。

<?php require_once ("../includes/session.php"); ?>
<?php require_once ("../includes/db_connection.php"); ?>
<?php require_once ("../includes/functions.php"); ?>
<?php require_once ("../includes/validation_function.php"); ?>

<?php
if (isset($_POST['submit'])) 
    // Process the form

    $menu_name = mysql_prep($_POST["menu_name"]);
    $position =  (int) $_POST["position"];
    $visible = (int) $_POST["visible"];

    // Validations
    $required_fields = array("menu_name", "position", "visible");
    validate_presences($required_fields);

    $fields_with_max_lengths = array("menu_name" => 30);
    validate_max_lengths($fields_with_max_lengths);

    if (!empty($errors)) 
        $_SESSION["errors"] = $errors;
        redirect_to("new_subject.php")
     <-------- THIS IS ROW 24! ----------->

        $query  = "INSERT INTO subjects (";
        $query .= "  menu_name, position, visible";
        $query .= ") VALUES (";
        $query .= "  '$menu_name, $position, $visible";
        $query .= ")";
        $result = mysqli_query($connection, $query);

    if ($result) 
        // Success
        $_SESSION["message"] = "Subject created!";
        redirect_to("manage_content.php");
     else 
        // Failure
        $_SESSION["message"] = "Subject creation failed";
        redirect_to("new_subject.php");
    

 else 

  // This is probably a GET request
  redirect_to("new_subject.php");


?>

<!-- Close database connection -->
<?php if (isset($connection))  mysqli_close($connection);  ?>

【参考方案1】：

大括号上方的行中缺少分号。

redirect_to("new_subject.php")

很多时候，您必须查看错误中给出的行上方的行，以了解问题所在。

【参考方案2】：

你错过了这一行的分号：

redirect_to("new_subject.php");

试试这个：

 if (!empty($errors)) 
        $_SESSION["errors"] = $errors;
        redirect_to("new_subject.php");
