我希望将我的网页标题设置为Ultan.me - 无论帖子标题是什么。我希望它显示帖子标题。帖子被提交到MySQL数据库,标题行被称为“标题”。这个小问题对任何帮助表示赞赏。
更新
现在是页面本身,但它不显示标题。我应该打开php文档并连接到我的数据库,与当前位置不同吗?
守则(唯一必要的部分是开头):

答案 0 :(得分:23)
这是我使用的方法(类似的东西,不仅仅是标题):
<?
ob_start (); // Buffer output
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
<head>
<title><!--TITLE--></title>
</head>
<body>
<?
$pageTitle = 'Title of Page'; // Call this in your pages' files to define the page title
?>
</body>
</html>
<?
$pageContents = ob_get_contents (); // Get all the page's HTML into a string
ob_end_clean (); // Wipe the buffer
// Replace <!--TITLE--> with $pageTitle variable contents, and print the HTML
echo str_replace ('<!--TITLE-->', $pageTitle, $pageContents);
?>
PHP通常可以执行任何代码并将所有输出直接打印到浏览器。如果您说"echo 'Some text here.';"
,该字符串将被发送到浏览器并从内存中清空。
输出缓冲的作用是&#34;将所有输出打印到缓冲区。抓住它。在我告诉您之前,请不要向浏览器发送任何内容。&#34;
所以它的作用是缓冲你的所有页面&#39; HTML进入缓冲区,然后在最后,在标记之后,它使用ob_get_contents()来获取缓冲区的内容(通常是您已经发送到浏览器的所有页面的HTML源代码)并把它放入一个字符串。
ob_end_clean()清空缓冲区并释放一些内存。我们不再需要源代码,因为我们只是将它存储在$ pageContents中。
然后,最后,我做了一个简单的发现&amp;对于&#39;&#39;的任何实例,请替换您网页的源代码($ pageContents)。并将它们替换为$ pageTitle变量设置的任何内容。当然,它会将<title><!--TITLE--></title>
替换为您的网页标题。在那之后,我回应$ pageContents,就像浏览器一样。
它有效地保留在输出上,因此您可以在将其发送到浏览器之前对其进行操作。
希望我的评论足够清楚。 在php手册(http://php.net/ob_start)中查找ob_start(),如果你想知道它是如何工作的(你应该):)
答案 1 :(得分:7)
您可以像往常一样从数据库中解析字段。
然后让我们说你把它放在一个名为$title
的变量中,你只是
<html>
<head>
<title>Ultan.me - <?php echo htmlspecialchars($title);?></title>
</head>
编辑:
我看到了你的问题。您必须在使用之前设置$title
。也就是说,您应该在<title>...
答案 2 :(得分:2)
将数据检索移到脚本的顶部,然后使用:
<title>Ultan.me - <?php echo htmlspecialchars($title, ENT_QUOTES, 'UTF-8'); ?></title>
答案 3 :(得分:2)
您需要在回显之前设置$title
的值。
此外,您应该在查询中使用它之前清理任何数据,因为这是一个安全风险
答案 4 :(得分:2)
header.php 将标题标记设置为<title>%TITLE%</title>;
&#34;%&#34;很重要,因为几乎没有人输入%TITLE%所以你可以在以后使用str_replace()。然后,你使用像这样的输出缓冲区
<?php
ob_start();
include("header.php");
$buffer=ob_get_contents();
ob_end_clean();
$buffer=str_replace("%TITLE%","NEW TITLE",$buffer);
echo $buffer;
?>

答案 5 :(得分:2)
如何使用以下内容:
<?php
$page_title = "Your page tile";
include("navigation.php"); // if required
echo("<title>$page_title</title>");
?>
答案 6 :(得分:2)
创建一个新页面php并添加以下代码:
<?php
function ch_title($title){
$output = ob_get_contents();
if ( ob_get_length() > 0) { ob_end_clean(); }
$patterns = array("/<title>(.*?)<\/title>/");
$replacements = array("<title>$title</title>");
$output = preg_replace($patterns, $replacements,$output);
echo $output;
}
?>
&#13;
在<head>
中添加代码:<?php require 'page.php' ?>
,并在每个页面上调用函数ch_title('my title');
答案 7 :(得分:1)
问题是,在第58行分配$title
之前,{{1}}被引用。重新排列代码并不容易,因为数据同时被检索和输出。只是为了测试,something like this work?
因为你只检索一行,所以你不需要使用while循环,但是我希望它能让你更容易与当前代码相关联。我所做的就是从数据检索中删除实际输出,并添加类别和类别名称的变量,这些变量稍后将被引用。另外,我没有测试过这个。 :)
答案 8 :(得分:1)
重新安排代码以使其工作会很棘手,但我会尝试:)
所以,把它放在代码的顶部:
<?php require_once('mysql.php'); ?>
文件顶部应如下所示:
<?php require_once('mysql.php'); ?>
<html>
<head>
<meta name="keywords" content="Mac user Ultan Casey TheCompuGeeks UltanKC">
<title>Ultan.me - <?php echo htmlspecialchars($title); ?> </title>
然后,在包含您引用的代码的文件所在的目录中创建一个名为mysql.php的文件。
这是mysql.php:
<?php
mysql_connect ('localhost', 'root', 'root');
mysql_select_db ('ultankc');
if (!isset($_GET['id']) || !is_numeric($_GET['id'])) {
die("Invalid ID specified.");
}
$id = (int)$_GET['id'];
$sql = "SELECT * FROM php_blog WHERE id='$id' LIMIT 1";
$result = mysql_query($sql) or print ("Can't select entry from table php_blog.<br />" . $sql . "<br />" . mysql_error());
$res = mysql_fetch_assoc($result);
$date = date("l F d Y", $res['timestamp']);
$title = $res['title'];
$entry = $res['entry'];
$get_categories = mysql_query("SELECT * FROM php_blog_categories WHERE `category_id` = $res['category']");
$category = mysql_fetch_array($get_categories);
?>
嗯,希望有所帮助:)

我知道这是一篇很老的帖子但读过这篇文章后我觉得这个解决方案要简单得多(虽然从技术上说它解决了Javascript而不是PHP的问题)。
<html>
<head>
<title>Ultan.me - Unset</title>
<script type="text/javascript">
function setTitle( text ) {
document.title = text;
}
</script>
<!-- other head info -->
</head>
<?php
// Make the call to the DB to get the title text. See OP post for example
$title_text = "Ultan.me - DB Title";
// Use body onload to set the title of the page
print "<body onload=\"setTitle( '$title_text' )\" >";
// Rest of your code here
print "<p>Either use php to print stuff</p>";
?>
<p>or just drop in and out of php</p>
<?php
// close the html page
print "</body></html>";
?>
答案 10 :(得分:0)
<?php echo APP_TITLE?> - <?php echo $page_title;?>
这应该适合你
答案 11 :(得分:0)
如果要将当前脚本文件名作为标题标签
在您的项目中包含功能
function setTitle($requestUri)
{
$explodeRequestUri = explode("/", $requestUri);
$currentFileName = end($explodeRequestUri);
$withoutExt = preg_replace('/\\.[^.\\s]{3,4}$/', '', $currentFileName);
$explodeCurrentFileName = explode("-", $withoutExt);
foreach ($explodeCurrentFileName as $curFileValue)
{
$fileArrayName[] = ucfirst($curFileValue);
}
echo implode(" ", $fileArrayName);
}
,并且在您的html中包含功能脚本 并以此替换您的标题标签
<title>Your Project Name -
<?php setTitle($_SERVER['REQUEST_URI']); ?>
</title>
它可以在php7及以上版本上运行,但我对php 5没有任何了解。* 希望对您有帮助
答案 12 :(得分:0)
只需在需要函数之前添加$ title变量
<?php
$title = "Your title goes here";
require("header.php");
?>
header.php
<title><?php echo $title; ?></title>
