错误代码，并不会在PHP中工作

2018-06-24 21:00:26

我之前发布了一些东西，这次我会发布所有这些。我收到错误消息，并且当我尝试在本地主机上将其拉出时，它不会显示。代码如下：

这个是includeindex.php

if ($_POST['submit'] != "") {
    if ($_POST['name'] != "") {
        session_start();
        $_SESSION['name'] = $_POST['name'];
        TopNavigation("PHP Includes Example - ECA236", "PHP Includes", $_SESSION['name']);
    } else {
        header("Location:includindex.php");
        exit;
    }
} else {
    TopNavigation("PHP Includes Example - ECA236", "PHP Includes");
    echo "<div class="formtable">n";
    echo "<br>";
    echo "<form action="" . $PHP_SELF . "" method="post">n";
    echo "Please enter your name:<input type="text" name="name">n";
    echo "<input type="submit" class="btnSubmit" value="Enter" name="submit">n";
    echo "</form>n";
    echo "<br>";
    echo "</div>n";
    Footer();
}

?>

这是头

<?php
function TopNavigation($pagetitle, $pageheading, $username = '') {
    echo "<html>n";
    echo "  <head>n";
    echo "  <title>" . $pagetitle . "</title>n";
    echo "  <link href="../style.css" type="text/css" rel="stylesheet">";
    echo "  </head>n";
    echo "  <body>";
    echo "      <h1>" . $pageheading . "</h1>n";
    echo "      <hr>n";
    echo "      <p class="tiny">" . date("F j,Y") . "</p>";
    if ($username != '') {
        echo "<div align="center">n";
        echo "<a href="includeindex.php">Use a different name</a> | <a href="about.php">About</a> | <a href="signout.php">Signout</a>n";
        echo "</div>n";
        echo "<p>Welcome. " . $username . "!";
    }
}

function Footer() {
    echo "</body>n";
    echo "</html>n";
}

?>

这个是about.php

<?php
session_start();
include("include/header.php");
if (!isset($_SESSION['name'])) {;
    header("Location:includeindex.php");
    exit;
} else {
    TopNavigation("About Me -ECA236", "About Me", $_SESSION['name']);

    echo "<p>Here is a little about me. I am a mother of twin girls who are 9 </p>"n;
    echo " < p>I been married for 5 years but been with my husband for 11 years </p > "n;
    echo "<p > I am attending college for Computer Programming and Database Mangament </p > "n;
    echo "<p > After I get done with this degree I am want to go back for Web Design </p > "n;
    echo "<p > since half my classes are web design now . I enjoy camping,bon fires and  </p > "n;
    echo "<p > playing video games, hanging out with friends and family .</p > "n;
    Footer();
}
?>

这是signout.php

<?php
session_start();
if (isset($_SESSION['name'])) {
    session_destroy();
    session_start();
}
header("Location:includeindex.php");
exit;
?>

我无法让它出现并工作。我不知道为什么它不这样做。有人可以帮帮我吗。

无论我修复了什么，我都会收到错误，并且在网上查看时它不会显示。

这里是我得到的错误：注意：未定义的变量：第19行中的C： wamp www includeindex.php中的PHP_SELF未定义索引：在第4行中的C： wamp www includeindex.php中提交警告：include（include / header.php）[function.include]：未能打开流：在第3行的C： wamp www about.php中没有这样的文件或目录警告：include（）[function.include]：打开'include /在C： wamp www about.php上包含（include_path ='.; C： php pear'）的header.php'致命错误：调用未定义函数TopNavigation（）in C： wamp 第9行的www about.php

TopNavigation()函数中的所有echo语句仍然被错误地引用。而不是"n;它们应该以n";结尾n";

// Wrong
echo "<p>Here is a little about me. I am a mother of twin girls who are 9 </p>"n;

// Should be:
echo "<p>Here is a little about me. I am a mother of twin girls who are 9 </p>n";
                                                                          ---^^^^

在您的php.ini中将display_errors = Off更改为display_errors = On
