How to change title of the page after including header.php? - php

page.php:
<?php
include("header.php");
$title = "TITLE";
?>
header.php:
<title><?php echo $title; ?></title>
I want my title to be set after including the header file. Is it possible to do this?

expanding on Dainis Abols answer, and your question on output handling,
consider the following:
your header.php has the title tag set to <title>%TITLE%</title>;
the "%" are important since hardly anyone types %TITLE% so u can use that for str_replace() later.
then, you can use output buffer like so
<?php
ob_start();
include("header.php");
$buffer=ob_get_contents();
ob_end_clean();
$buffer=str_replace("%TITLE%","NEW TITLE",$buffer);
echo $buffer;
?>
and that should do it.
EDIT
I believe Guy's idea works better since it gives you a default if you need it, IE:
The title is now <title>Backup Title</title>
Code is now:
<?php
ob_start();
include("header.php");
$buffer=ob_get_contents();
ob_end_clean();
$title = "page title";
$buffer = preg_replace('/(<title>)(.*?)(<\/title>)/i', '$1' . $title . '$3', $buffer);
echo $buffer;
?>

1. Simply add $title variable before require function
<?php
$title = "Your title goes here";
require("header.php");
?>
2. Add following code into header.php
<title><?php echo $title; ?></title>

What you can do is, you store the output in a variable like:
header.php
<?php
$output = '<html><title>%TITLE%</title><body>';
?>
PS: You need to remove all echos/prints etc so that all possible output is stored in the $output variable.
This can be easely done, by defining $output = ''; at the start of the file and then find/replace echo to $output .=.
And then replace the %TITLE% to what you need:
<?php
include("header.php");
$title = "TITLE";
$output = str_replace('%TITLE%', $title, $output);
echo $output;
?>
Another way is using javascript in your code, instead of:
<title><?php echo $title; ?></title>
Put this in there:
<script type="text/javascript">
document.title = "<?=$title;?>"
</script>
Or jQuery, if you prefer:
<script type="text/javascript">
$(document).ready(function() {
$(this).attr("title", "<?=$title;?>");
});
</script>

Expanding a little on we.mamat's answer,
you could use a preg_replace instead of the simple replace and remove the need for a %title% altogether. Something like this:
<?php
ob_start();
include("header.php");
$buffer=ob_get_contents();
ob_end_clean();
$title = "page title";
$buffer = preg_replace('/(<title>)(.*?)(<\/title>)/i', '$1' . $title . '$3', $buffer);
echo $buffer;
?>

you can set using JavaScript
<script language="javascript">
document.title = "The new title goes here.";
</script>

Add this code on top your page
<?php
$title="This is the new page title";
?>
Add this code on your Template header file (include)
<title><?php echo $title; ?></title>

It's very easy.
Put this code in header.php
<?
$sitename = 'Your Site Name'
$pagetitle;
if(isset($pagetitle)){
echo "<title>$pagetitle." | ". $sitename</title>";
}
else {
echo "<title>$sitename</title>";
}
?>
Then in the page put there :
<?
$pagetitle = 'Sign up'
include "header.php";
?>
So if you are on Index.php , The title is Your Site Name.
And for example if you are on sign up page , The title is Sign up | Your Site Name

Every Simple just using a function , I created it .
<?
function change_meta_tags($title,$description,$keywords){
// This function made by Jamil Hammash
$output = ob_get_contents();
if ( ob_get_length() > 0) { ob_end_clean(); }
$patterns = array("/<title>(.*?)<\/title>/","<meta name='description' content='(.*)'>","<meta name='keywords' content='(.*)'>");
$replacements = array("<title>$title</title>","meta name='description' content='$description'","meta name='keywords' content='$keywords'");
$output = preg_replace($patterns, $replacements,$output);
echo $output;
}
?>
First of all you must create function.php file and put this function inside ,then make require under the MetaTags in Header.php .
To use this function change_meta_tags("NEW TITLE","NEW DESCRIPTION",NEW KEYWORDS); .
Don't use this function in Header.php !! just with another pages .

Use a jQuery function like this:
$("title").html('your title');

How to include file in PHP with user defined variable

I am trying to include file in string replace but in output i am getting string not the final output.
analytic.php
<?php echo "<title> Hello world </title>"; ?>
head.php
<?php include "analytic.php"; ?>
index.php
string = " <head> </head>";
$headin = file_get_contents('head.php');
$head = str_replace("<head>", "<head>". $headin, $head);
echo $head;
Output i am getting :
<head><?php include "analytic.php"; ?> </head>
Output i need :
<head><title> Hello world </title> </head>
Note : Please do not recommend using analytic.php directly in index.php because head.php have some important code and it has to be merged analytic.php with head.php and then index.php
To get the desired output :
function getEvaluatedContent($include_files) {
$content = file_get_contents($include_files);
ob_start();
eval("?>$content");
$evaluatedContent = ob_get_contents();
ob_end_clean();
return $evaluatedContent;
}
$headin = getEvaluatedContent('head.php');
string = " <head> </head>";
$head = str_replace("<head>", "<head>". $headin, $head);
echo $head;
Output will be output string not file string :
<head><title> Hello world </title> </head>
I think your approach is pretty basic (you try to hardcore modify - programmerly edit - the template script, right?) but anyway:
$file = file('absolut/path/to/file.php');
foreach ($file as $line => $code) {
if (str_contains($code, '<head>')) {
$file[$line] = str_replace('<head>', '<head>' . $headin, $code);
break;
}
}
file_put_contents('absolut/path/to/file.php', $file);

PHP automatically pre- and append dynamic content to output

Is there a way to automatically include content before and after the actual output of a file?
Why? For example to use this to include everything up to the main content (dynamcally generated HTML, head, opening tags...) and after the file runs, automatically close everything up again.
I know of the ob_start approach, but I'm not sure if dynamically generated content is easy to include that way:
<?php
function bootstrap_page($content) {
return "text before" . $content . "text after";
}
ob_start(bootstrap_page);
?>
But then, ob cannot be used to capture the output of an include within the callback, AFAIK. So that makes it hard to easily pre- and append something dynamically generated. I could use long strings in the callback function to get a static version working - but is there a way to do this more seamlessly?
In other words I'm basically trying to include a php file before and one after any (other) file I need and that - if possible reduced to a function call at the start of a given file.
The functionality I'm looking for would transform this:
<?php
bootstrap_this();
?>
<p>Lorem ipsum</p>
before.php:
<!DOCTYPE html>
<html>
<?php include('head.php'); ?>
<body>
<?php if(somecondition) { ?>
<h1>Hello, World!</h1>
<?php } ?>
after.php:
</body>
</html>
Into something like this:
<?php
include 'before.php';
?>
<p>Lorem ipsum</p>
<?php
include 'after.php';
?>
And in the end into:
<!DOCTYPE html>
<html>
<?php include('head.php'); ?>
<body>
<?php if(somecondition) { ?>
<h1>Hello, World!</h1>
<?php } ?>
<p>Lorem ipsum</p>
</body>
</html>
Isn't that what output buffering is for?
<?php
// Start Buffer
ob_start();
// Include before
include 'before.php';
?>
<p>Lorem ipsum</p>
<?php
// Include after
include 'after.php';
// Get buffered output
$page = ob_get_clean();
echo $page;
?>
But then, ob cannot be used to capture the output of an include within the callback, AFAIK
AFAYK ? Would it be hard to test? As long as the include is after ob_start() and the code does not explicitly call ob_flush() before you choose to do so, then it will capture the output.
I'm basically trying to include a php file before and one after any (other) file I need
That implies some set sort of controlling script which calls the pre-oinclude, the main content and the post-include.
That would be OK if HTML (not true, I'll come back to that) did not have a defined root which should be explicitly declared. And you have the issue HTTP also has a structure which you risk subverting here - headers come before content. But leaving those aside for now, HTML requires a nested structure. All tags should be closed. Opening and closing tags in different files is messy and bad practice.
There are a whole lot technologies which provide the end result you appear to be looking for - ESI, templating and front-controller patterns all provide this in a much more structured way.
I'm not sure I see the usage of this or if I understood this correct, but if I understood it correctly you're looking for something like this:
<?php
function dynamice_include($before, $content, $after) {
$dynamic_content = '';
$dynamic_content .= include $before . '.php';
$dynamic_content .= $content;
$dynamic_content .= include $after . '.php';
return $dynamic_content;
}
Usage:
$content = dynamice_include('before', 'Hello I am really cool','after');
echo $content;
In before.php and after.php a return would be required, e.g.
before.php
<?php
return "wow before";
after.php
<?php
return "wow after";
and the result would be:
wow beforeHello I am really coolwow after
UPDATE:
It seems it more something like this you're looking for. output-buffers are the only way AFAIK to achieve this.
This code is not optimized at all... (I just show the concept here)
<?php
function dynamice_include($before, $content, $after) {
$dynamic_content = '';
ob_start();
include $before . '.php';
$dynamic_content .= ob_get_contents();
ob_end_clean();
ob_start();
include $content . '.php';
$dynamic_content .= ob_get_contents();
ob_end_clean();
ob_start();
include $after . '.php';
$dynamic_content .= ob_get_contents();
ob_end_clean();
return $dynamic_content;
}
$content = dynamice_include('before', 'dytest','after');
echo $content;
As other stated though - it's a lot of platforms, frameworks, template engines out there that could solve this issue. You will have do ob_start() and ob_clean within the current files content for this to work.
UPDATE2:
In this case I fetch current files output buffer as content.
<?php
function dynamice_include($before, $content, $after) {
$dynamic_content = '';
ob_start();
include $before . '.php';
$dynamic_content .= ob_get_contents();
ob_end_clean();
$dynamic_content .= $content;
ob_start();
include $after . '.php';
$dynamic_content .= ob_get_contents();
ob_end_clean();
return $dynamic_content;
}
ob_start();
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
</head>
<body>
feelings
</body>
</html>
<?php
$content = ob_get_contents();
ob_end_clean();
$content = dynamice_include('before', $content, 'after');
echo $content;
?>
Thanks to the help of #bestprogrammerintheworld, I came up with this:
function use_template($before = 'pre', $after = 'post') {
ob_start();
include $before . '.php';
$pre = ob_get_contents();
ob_end_clean();
ob_start();
include $after . '.php';
$post = ob_get_contents();
ob_end_clean();
$bootstrap_page = function ($content) use ($pre, $post) {
return $pre . $content . $post;
};
ob_start($bootstrap_page);
}
If this function is called a the beginning of a php file, the outputs of before.php and after.php get stored and bound to the callback. Then, after all the main output is read, everything is pieced together. No code at the end of the file required.
Since ob cannot be run within the callback, bootstrap_page, it must be run beforehand to capture the other files first.

Change meta description on each page with php after header

I ma trying to change dynamically the meta description on each page with php after header.php file.
I currently change my page title by this code:
<?php
require 'config.php';
include 'logout.php';
require 'header.php';
$buffer=ob_get_contents();
ob_end_clean();
$title = "Title of each page";
$buffer = preg_replace('/(<title>)(.*?)(<\/title>)/i', '$1' . $title . '$3', $buffer);
echo $buffer;
//rest of page
?>
and is working.
I tried to do the same for <meta name="description" content="content">
by adding the following code exactly under the title one:
$buffer_meta = ob_get_contents();
ob_end_clean();
$meta_description = "meta content";
$buffer_meta = preg_replace('/(<meta name="description" content=")(.*?)(">)/i', '$1' . $meta_description. '$3', $buffer_meta);
echo $buffer_meta;
But is not working.
On var_dump($buffer_meta) i get string 0 a null result.
Any feedback?

How do I populate a variable using a function?

I have the code below on a page basically what I'm trying to do is fill $content variable using the function pagecontent. Anything inside pagecontent function should be added to the $content variable and then my theme system will take that $content and put it in theme. From the answers below it seems you guys think I want the html and php inside the actual function I don't.
This function below is for pagecontent and is what I'm currently trying to use to populate $content.
function pagecontent()
{
return $pagecontent;
}
<?php
//starts the pagecontent and anything inside should be inside the variable is what I want
$content = pagecontent() {
?>
I want anything is this area whether it be PHP or HTML added to $content using pagecontent() function above.
<?php
}///this ends pagecontent
echo functional($content, 'Home');
?>
I think you're looking for output buffering.
<?
// Start output buffering
ob_start();
?> Do all your text here
<? echo 'Or even PHP output ?>
And some more, including <b>HTML</b>
<?
// Get the buffered content into your variable
$content = ob_get_contents();
// Clear the buffer.
ob_get_clean();
// Feed $content to whatever template engine.
echo functional($content, 'Home');
As you are obviously a beginner here's a much simplified, working version to get you started.
function pageContent()
{
$html = '<h1>Added from pageContent function</h1>';
$html .= '<p>Funky eh?</p>';
return $html;
}
$content = pageContent();
echo $content;
The rest of the code you post is superfluous to your problem. Get the bare minimum working first then move on from there.
Way 1:
function page_content(){
ob_start(); ?>
<h1>Hello World!</h1>
<?php
$buffer = ob_get_contents();
ob_end_clean();
return $buffer;
}
$content .= page_content();
Way 2:
function page_content( & $content ){
ob_start(); ?>
<h1>Hello World!</h1>
<?php
$buffer = ob_get_contents();
ob_end_clean();
$content .= $buffer;
}
$content = '';
page_content( $content );
Way 3:
function echo_page_content( $name = 'John Doe' ){
return <<<END
<h1>Hello $name!</h1>
END;
}
echo_page_content( );

Dynamic Title Tag in PHP

I am trying to dynamically populate the title tag on a website. I have the following code in my index.php page
<?php $title = 'myTitle'; include("header.php"); ?>
And the following on my header page
<title><?php if (isset($title)) {echo $title;}
else {echo "My Website";} ?></title>
But no matter what I do, I cannot get this code to work. Does anyone have any suggestions?
thanks
This works (tested it - create a new folder, put your first line of code in a file called index.php and the second one in header.php, run it, check the title bar).
You should double check if those two files are in the same folder, and that you're including the right header.php from the right index.php. And ensure that $title is not being set back to null somewhere in your code.
Learn more about Variable Scope here.
Edit: Examples of visible changes would be:
TEST1<?php $title = 'myTitle'; include("header.php"); ?>
<title>TEST2<?php if ...
Are you including the header file before or after you set the title variable? If you're including it before, then of course it won't be set.
if you're doing something like this in your index.php:
<?php
include('header.php');
$title = "blah blah blah";
?>
then it won't work - you include the header file and output the title text before the $title variable is ever set.
try to declare the variable before using it
$title = '123';
require 'includes/header.php';
Hi Try this old school method ..
In your Header file (for e.g. header.php)
<?php
error_reporting(E_ALL);
echo '<!DOCTYPE html>
<!--[if IE 7 ]><html class="ie7" lang="en"><![endif]-->
<!--[if IE 8 ]><html class="ie8" lang="en"><![endif]-->
<!--[if IE 9 ]><html class="ie9" lang="en"><![endif]-->
<!--[if (gte IE 10)|!(IE)]><!-->
<html xmlns="http://www.w3.org/1999/xhtml" lang="en-US">
<!--<![endif]-->
<head>';
?>
<?php
if($GLOBALS['title']) {
$title = $GLOBALS['title'];
} else {
$GLOBALS['title'] = "Welcome to My Website";
}
if($GLOBALS['desc']) {
$desc = $GLOBALS['desc'];
} else {
$desc = "This is a default description of my website";
}
if($GLOBALS['keywords']) {
$keywords = $GLOBALS['keywords'];
} else {
$keywords = "my, site, key, words";
}
echo "\r\n";
echo "<title> ". $title ." | MyWebsite.com </title>";
echo "\r\n";
echo "<meta name=\"description\" content='". $GLOBALS['title']."'>";
echo "\r\n";
echo "<meta name=\"keywords\" content='".$GLOBALS['title']."'>";
echo "\r\n";
?>
In you PHP Page file do like this (for example about.php)
<?php
$GLOBALS['title'] = 'About MyWebsite -This is a Full SEO Title';
$GLOBALS['desc'] = 'This is a description';
$GLOBALS['keywords'] ='keyword, keywords, keys';
include("header.php");
?>
I assume your header is stored in a different file (could be outside the root directory) then all the above solutions will not work for you because $title is set before it is defined.
Here is my solution:
in your header.php file you need to set the $title to be global by: global $title; then echo it in your title so:
<?php global $title; ?>
<title><?php echo isset($title) ? $title : "{YOUR SITE NAME}"; ?></title>
Then in every page now you can define your title after you have included your header file so for example in your index.php file:
include_once("header.php");
$title = "Your title for better SEO"
This is tested and it is working.
We can also use functions and its a good way to work on real time web sites.
Do simple:
create an index.php file and paste these lines:
<?php include("title.php");?>
<!doctype html>
<html>
<head>
<title><?php index_Title(); ?></title>
<head>
</html>
-- Then
Create a title.php file and paste these lines:
<?php
function index_Title(){
$title = '.:: itsmeShubham ::.';
if (isset($title)){
echo $title;
}else{
echo "My Website";
};
}
?>
It will work perfectly as you want and we can also update any title by touching only one title.php file.
<?php
echo basename(pathinfo($_SERVER['PHP_SELF'])['basename'],".php");
?>
This works. Since I'm using PHP I don't check for other extensions; use pathinfo['extension'] in case that's required.
You can achieve that by using define(); function.
In your header.php file add following line :
<title><?php echo TITLE; ?></title>
And on that page where you want to set dynamic title, Add following lines:
EX : my page name is user-profile.php where I want to set dynamic title
so I will add those lines that page.
<?php
define('TITLE','User Profile'); //variable which is used in header.php
include('header.php');
include('dbConnection.php');
?>
So my user-profile/.php file will be having title: User Profile
As like this you can add title on any page on your site
Example Template.php
<?php
if (!isset($rel)) {$rel = './';}
if (!isset($header)) {
$header = true;
?><html>
<head>
<title><?php echo $pageTitle; ?></title>
</head>
<body>
<?php } else { ?>
</body>
</html><?php } ?>
Pages Your Content
<?php
$rel = './'; // location of page relative to template.php
$pageTitle = 'This is my page title!';
include $rel . 'template.php';
?>
Page content here
<?php include $rel . 'template.php'; ?>
I'm using your code in my project and it works properly
My code in header:
<title>
<?php
if (isset($title)) {echo $title;}
else {echo "عنوانی پیدا نشد!";}
?>
</title>
and my code in index.php:
<?php
$title = "سرنا صفحه اصلی";
include("./include/header-menu.php");
?>
