为什么我的PHP代码中出现“意外的$ end”？

Question

I do not know what im doing wrong. 我不知道我做错了什么。 I have been looking through other forums that say my problem might be related to not having closed curly braces closed or a short php tag <? ... 我一直在寻找其他论坛，说我的问题可能与没有关闭大括号关闭或短的PHP标签<? ... <? ... . <? ... I have none of these as far as I can tell. 据我所知，我没有这些。 This is a form that lets you know if any fields are left blank. 这是一个表单，可以让您知道是否有任何字段留空。

<?php

if (count($_POST) > 0)
{

    function check_if_field_submitted($field_to_check)
    {
        if (isset($_POST[$field_to_check]) && $_POST[$field_to_check] != '')
        {
            return TRUE;
        }
        else
        {
            return "YOU MUST FILL IN THE $field_to_check FIELD!";
        }
    }

    //--------------------------------------------------------

    $error_messages = array();

    //Validate the input

    //Trim the fields
    $_POST['first_name'] = trim($_POST['first_name']);
    $_POST['last_name'] = trim($_POST['last_name']);
    $_POST['comments'] = trim($_POST['comments']);
    $_POST['first_name'] = strip_tags($_POST['first_name']);
    $_POST['last_name'] = strip_tags($_POST['last_name']);
    $_POST['comments'] = strip_tags($_POST['comments']);

    //Required fields:

    if (check_if_field_submitted('first_name') !== TRUE)
    {
        $error_messages[] = check_if_field_submitted('first_name');
    }

    if (check_if_field_submitted('last_name') !== TRUE)
    {
        $error_messages[] = check_if_field_submitted('last_name');    
    }

    if (check_if_field_submitted('hobbies') !== TRUE)
    {
        $error_messages[] = check_if_field_submitted('hobbies');
    }

    if (check_if_field_submitted('university') !== TRUE)
    {
        $error_messages[] = check_if_field_submitted('university');
    }

    if (check_if_field_submitted('year') !== TRUE)
    {
        $error_messages[] = check_if_field_submitted('year');
    }

    if (check_if_field_submitted('comments') !== TRUE)
    {
        $error_messages[] = check_if_field_submitted('comments');

    if (count($error_messages) < 1)
    {
        header("Location: success.php");
    }
}

Answer 1

Problem: 问题：

 if (check_if_field_submitted('comments') !== TRUE)
        {
            $error_messages[] = check_if_field_submitted('comments');




if (count($error_messages) < 1)
    {

        header("Location: success.php");
    }

}

Answer: 回答：

 if (check_if_field_submitted('comments') !== TRUE)
            {
                $error_messages[] = check_if_field_submitted('comments');

            }


    if (count($error_messages) < 1)
        {

            header("Location: success.php");
        }

    }

If I were you I would find an IDE with bracket matching/highlighting. 如果我是你，我会找到一个带支架匹配/突出显示的IDE。

Answer 2

It looks like you're missing a closing brace on one of your if statements. 看起来你错过了一个if语句的结束括号。

I think you want to change these lines: 我想你想改变这些方面：

        if (check_if_field_submitted('comments') !== TRUE)
        {
            $error_messages[] = check_if_field_submitted('comments');

to this: 对此：

        if (check_if_field_submitted('comments') !== TRUE)
        {
            $error_messages[] = check_if_field_submitted('comments');
        }
