我试图从PHP动态设置页面的HTML标题。 我有一个页面，它根据数据库中的条目设置title元素。 我试图根据当前页面的H2内容动态更改标题。 再次从数据库中检索此内容。
我试图使用会话变量来做到这一点，但显然由于加载顺序，这在加载标题时不起作用，然后是内容。 在页面刷新，然后正确设置标题，但这不是很好。
我目前正在使用JavaScript来更新标题，但这对于没有启用JS的搜索引擎机器人来说也没有用。
PHP
session_start(); <--both header and dynamic page --> <title><?php echo $_SESSION['dynamictitle'];?></title> <-- Header --> $jobTitle = $rs2row['fldRoleTitle']; <-- dynamic page --> $_SESSION['dynamictitle'] = $jobTitle;JavaScript的
var currentTitle = "<?php Print($jobTitle) ?>" + " | " + document.title; document.title = currentTitle;I am trying to set the HTML title of a page dynamically from PHP. I have a page which sets the title element based upon an entry in a database. I am trying to make the title change dynamically based on the current page's H2 content. This content is, once again, retrieved from the database.
I have tried to do this using session variables, but obviously due to the load order this doesn't work as the header is loaded, and then the content. On page refresh the title is then set correctly, but this is not good.
I currently am using JavaScript to update the title but again this is no good for search engine bot that don't have JS enabled.
PHP
session_start(); <--both header and dynamic page --> <title><?php echo $_SESSION['dynamictitle'];?></title> <-- Header --> $jobTitle = $rs2row['fldRoleTitle']; <-- dynamic page --> $_SESSION['dynamictitle'] = $jobTitle;JavaScript
var currentTitle = "<?php Print($jobTitle) ?>" + " | " + document.title; document.title = currentTitle;最满意答案
将模板的数据加载和处理与模板的实际输出/呈现分开，例如在将变量放入模板之前确定变量，例如
<?php // handlerForThisPage.php session_start(); $dynamicTitle = $_SESSION['dynamictitle']; … $jobTitle = $rs2row['fldRoleTitle']; … include '/path/to/header.html'; include '/path/to/templateForThisPage.html';然后只需回显相应模板中的变量，例如
// header.html <html> <head> <title><?php echo $dynamicTitle ?></title> …什么应该进入templateForThisPage.html然后。 这比在一个大杂乱的文件中混合数据获取，处理和输出的线性脚本更方便和更容易维护。 如果您想扩展此方法，请考虑阅读有关MVC模式的内容。
Separate the loading and processing of the data for the template from the actual output/rendering of the template, e.g. determine the variables before putting them in the template, e.g.
<?php // handlerForThisPage.php session_start(); $dynamicTitle = $_SESSION['dynamictitle']; … $jobTitle = $rs2row['fldRoleTitle']; … include '/path/to/header.html'; include '/path/to/templateForThisPage.html';And then just echo the variables in the respective templates, e.g.
// header.html <html> <head> <title><?php echo $dynamicTitle ?></title> …and whatever should go into templateForThisPage.html then. This is much more convenient and sane to maintain than having a linear script mixing data fetching, processing and output in one big messy file. If you want to extend on this approach, consider reading about the MVC pattern.
