【问题描述】:
对于这个问题的冗长,我深表歉意,并提前表示感谢。
以下是相关代码的 sn-p。我有一个 MySQL 表,它存储来自基于本教程的自定义构建的 PHP MySQL CMS 程序的信息:cms tutorial。正如您在 List Pages 和 Display Admin 函数中看到的那样,URL 是使用基本 url 和 ID 以及标题构建的。 ID 是 MySQL 表中的主键,它提取所有必要的信息以显示在页面上。我将如何重写下面的代码,使其仅在 URL 中而不是 ID 中显示标题,但仍然不使用 ID 作为在页面中显示信息的唯一标识符?
来自functions.php:
'// Display center bottom column
function centerbottomcolumn() {
if ($_GET['id']) {
$pageID = (int) $_GET['id'];
$result = mysql_query("SELECT centerbottomcolumn FROM pages WHERE id='$pageID'");
$row = mysql_fetch_array($result);
echo $row['centerbottomcolumn'];
} else {
$result = mysql_query("SELECT value FROM settings WHERE name='homePage'");
$row = mysql_fetch_array($result);
$pageID = $row['value'];
$result = mysql_query("SELECT centerbottomcolumn FROM pages WHERE title='$pageID'");
$row = mysql_fetch_array($result);
echo $row['centerbottomcolumn'];
}
}
// List the pages
function listPages() {
// List the home page first
$result = mysql_query("SELECT value FROM settings WHERE name='homePage'");
$row = mysql_fetch_array($result);
$homeID = $row['value'];
$result = mysql_query("SELECT title FROM pages WHERE id='$homeID'");
$row = mysql_fetch_array($result);
$homeTitle = $row['title'];
echo "<li><a href='" . BASE_URL . "/index.php'>$homeTitle</a></li>";
// List the rest of the pages
$result = mysql_query("SELECT id, title FROM pages");
while ($row = mysql_fetch_array($result)) {
// Do not list the home page twice
if ($row['title'] != $homeID) {
$pageID = $row['title'];
$pageTitle = $row['title'];
echo "<li><a href='" . BASE_URL . "/?id=$id&title=$pageTitle'>$pageTitle</a></li>";
}
}
}
// Display admin table
function displayAdmin() {
// Find the home page ID
$result = mysql_query("SELECT value FROM settings WHERE name='homePage'");
$row = mysql_fetch_array($result);
$homeID = $row['value'];
// Display a table
$result = mysql_query("SELECT id, title, date FROM pages");
echo '<table width="961">';
echo '<tr height="50">
<th align="left">ID</th>
<th align="left">Title of the Page</th>
<th align="left">Date Created</th>
<th align="left">Actions</th>
</tr>';
while ($row = mysql_fetch_array($result)) {
$id = $row['id'];
$title = $row['title'];
$date = date('M d, Y', $row['date']);
echo "<tr>
<td>$id</td>
<td><a href='". BASE_URL . "/id=$id&title=$title'>$title</a>";
if ($id == $homeID) {
echo ' <strong>(Home Page)</strong>';
}
echo "</td>
<td>$date</td>
<td><a href='edit.php?id=$id'>Edit</a></td><td>
<a href='confirm.php?id=$id'>Delete</a></td><td>
<a href='sethome.php?id=$id'>Set as Home</a>";
}
echo '</table>';
}
// Get array with page IDs
function getArray() {
$result = mysql_query("SELECT id FROM pages");
$IDs = array();
$i = 0;
while ($row = mysql_fetch_array($result)) {
$IDs[$i] = $row['id'];
$i++;
}
return $IDs;
}
From index.php:
(above head tag)
require_once 'functions.php';
connect();
$IDs = getArray();
(from body)
<?php if (in_array($_GET['id'], $IDs) || !$_GET): ?>
<?php centerbottomcolumn(); ?>
<?php else: ?>
<!-- Show a not found error -->
<p>Not found</p>
<?php endif; ?>'
