I write my template in index.php using bootstrap.
In this template there is a place <div id="content"></div> which is dynamic content of this site.
It means that, there I want to change the content.
Other for login.php , register.php, news.php page etc...
Okey I can copy this template(from index.php) to all of these pages but it is not good idea. If I want to change something static (like menu) I should do it in all pages.
I can use mysql to generate menu of course, but I want to include other pages (which is need) to index.php content div
Best Regards.
Okey I have one template (in html + js - bootstrap) which have static elements for example navbar, logo etc...
But this template have one dynamic element I mean - div = content it change depending on which site is user watching (login.php,register.php etc...)
How to include this template to all subpages for example login.php,register.php etc... without copy and paste it everywhere ?
A basic solution could be to create a layout.php page containing your whole template, and just put a where your content is supposed to be.
Then, on each page, set your $content variable with the html of your page and just include layout.php then. A better solution is to implement the MVC design pattern, but it's more "complicated".
From personal experience, I find that it's best to break down every component of the page, for example I'll have
<?php
$pageTitle = "MyAwesomeWebpage";
require_once('header.php'); //Contains Doctype, HTML header tags
require_once('navbar.php'); //Contains navigation
?>
// Unique content here
<?php require_once('footer.php'); ?>
header.php example:
<!DOCTYPE html>
<html lang="en"><!-- ended in footer.php -->
<meta content= .... />
<title><?php echo $pageTitle; ?></title>
<link rel="stylesheet" href="mystyle.css" />
<!-- .... Other links and styles here -->
<body> <!-- ended in footer.php -->

I'm looking for advice on the best practice for separating site content up into logical blocks. I want a header and footer that are constant throughout the site, so that if I have several pages of different content, they will all look as below — changes made to the header and footer then update automatically without me having to change each individual page.
<?php
include 'header.php';
?>
<body>
<p>page content here</p>
</body>
<?
include 'footer.php';
?>
The header.php would contain the opening <html>, <head> and static content, and the footer.php would contain any extra static content and the closing </html> tag. So, my question is: Is this a good approach? I'm worried that spreading the <html> tags across multiple files is bad practice. If so, what is the right way to approach this kind of design?
Nope, your approach is wrong.
Here are main faults in your design:
You're assuming that header.php would be called on the every page call. That's wrong.
You're assuming that header.php will always be static. That's wrong.
You forgot to create a template for the page itself.
The main rule everyone have to learn by heart:
Not a single character has to be sent into browser, until all data gets ready.
Why?
it's 2011 today. AJAX era. What if your code will have to send JSONed data instead of whole HTML page?
there is a thing called HTTP header. Sometimes we have to send them. And it's gets impossible if you already have your ornate HTML header sent.
it's for just 4-page site. Okay. Imagine you've got lucky and got a request for another 4-page site. You will have to change only templates and don't touch engine files. That's really great benefit.
Imagine you're going to make a custom <title> tag for your pages, based on the page content. Isn't it extremely common thing? But you can't make it without using templates.
So, you have to have one common site template containing header and footer and also dedicated templates for the every php script.
An example layout is going to be like this:
.1. page itself.
it outputs nothing but only gather required data and calls a template:
<?php
//include our settings, connect to database etc.
include dirname($_SERVER['DOCUMENT_ROOT']).'/cfg/settings.php';
//getting required data
$DATA=dbgetarr("SELECT * FROM links");
$pagetitle = "Links to friend sites";
//etc
//and then call a template:
$tpl = "links.tpl.php";
include "template.php";
?>
.2. template.php which is your main site template,
consists of your header and footer:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>My site. <?=$pagetitle?></title>
</head>
<body>
<div id="page">
<?php include $tpl ?>
</div>
</body>
</html>
.3. and finally links.tpl.php is the actual page template:
<h2><?=$pagetitle?></h2>
<ul>
<?php foreach($DATA as $row): ?>
<li><?=$row['name']?></li>
<?php endforeach ?>
<ul>
easy, clean and maintainable.
In building off of Your Common Sense's answer, there's not a good reason to have 2 files for every page. You can easily combine your template (YCS called this .tpl.php) and your actual page into one file.
First, start off with a class that you can expand as your template needs expand:
<?php
#lib/PageTemplate.php
class PageTemplate {
public $PageTitle;
public $ContentHead;
public $ContentBody;
}
Then, make your layout:
<?php
# layout.php
require_once('lib/PageTemplate.php');
?>
<!DOCTYPE HTML>
<html>
<head>
<title><?php if(isset($TPL->PageTitle)) { echo $TPL->PageTitle; } ?></title>
<?php if(isset($TPL->ContentHead)) { include $TPL->ContentHead; } ?>
</head>
<body>
<div id="content">
<?php if(isset($TPL->ContentBody)) { include $TPL->ContentBody; } ?>
</div>
</body>
</html>
And finally, add your page with the body content:
<?php
#Hello.php
require_once('lib/PageTemplate.php');
# trick to execute 1st time, but not 2nd so you don't have an inf loop
if (!isset($TPL)) {
$TPL = new PageTemplate();
$TPL->PageTitle = "My Title";
$TPL->ContentBody = __FILE__;
include "layout.php";
exit;
}
?>
<p><?php echo "Hello!"; ?></p>
This is a basic approach but, yeah, it does work :) I sure would bother with a lot of templating and OOP but you are definitely on the right path
As i can't comment anymore, then i will answer here ;) If he need a custom title then he needs some more advanced functions. So, as i told, this is a basic approach. But in the end, if he really have a static header/footer, and really use them everywhere, well, yes, this is a good way to go.
So ofc you could bother with some advanced headers with parameters you could feed on each page. You could go on a whole MVC stuff. In the end just tell him to use a pre-made framework and stop bothering. How could he learn if you don't let him do some trial and error ?
index.php -- includes header, footer, and content based on REQUEST variable.
header.php -- header content
footer.php -- footer content
content1.php, content2.php, etc.
index.php:
<?php
include ('header.php');
// VERY IMPORTANT - do not use the GET variable directly like this
// make sure to filter it through a white-list
include(basename($_GET['page']).'.php');
include ('footer.php');
?>
if you want the URL to go www.domain.com/pagename where the page you're trying to load into index.php is "pagename", use HTACCESS and do some URL Rewriting: http://corz.org/serv/tricks/htaccess2.php
I am new in web designing.my website is based on articles.I want that it must be searchiable by search engine and each page open with header and footer of site with it direct link example let I have article on WiFi_connectivity.html in directory root/article than link is
Mysite.com/article/WiFi_connectivity.html;
But point is that I don't want add header and footer in each page and page should have its original link for that article for bookmark or else
You would just include the header and footer files like so:
<?php
//set variables for your head tags here. title, keywords etc....
include('header.php');
//Your content goes here
include('footer.php');
?>
Your header.php file would look something like this:
<!DOCTYPE html>
<html lang="en-US">
<head>
<title><?php echo $title; ?></title>
<meta keywords="<?php echo $keywords; ?>"
</head>
//the rest of your header.php code here
To keep it SE friendly do all of your code above the first include so you can add proper title, meta tags, etc to the header file. Then just name the page what ever relevant name you like and it will retain the dynamic title for bookmarks.
This is an overly simple version but it is just to give you a rough idea of where to start.
I'm quite new to the whole php scene but I have managed to make a php header and footer and include them on my pages so I dont have to edit the header and footer on each page now. My next challenge is making a whole template for something like a blog page where if I change the template then all the blog pages will change accordingly but the content will of course have to remain the same much like the php header and footers I have. I have read a bit about theme engines etc but they all seem to be quite confusing, and I don't wish to convert it to wordpress. So what are my options as to making a template? thank you in advance.
You can simply use smarty, powerfull template engine for PHP.
First - create template with html base, header, footer. Save it to templates/_Frame.html
<!DOCTYPE html>
<html>
<head>
<title>{block name='Title'}{/block} - My website</title>
</head>
<body>
<div>Header and some other stuff</div>
{block name='Content'}{/block}
<div>Footer and some other stuff</div>
</body>
</html>
Then, crate a template file for each page. If its a blog with same look on each page and the only variable thing is the post content - you need only 1 template. Lets call it 'Post.html'
{extends '_Frame.html'}
{block name='Title'}{$Post.Title|escape}{/block}
{block name='Content'}{$Post.Content}{/block}
In php - do such thing:
<?php
//Lets say at this poin you've got $BlogPost = array('Title' => 'Blog post title', 'Content' => 'Body of blog post')
$S = new Smarty();
$S->assign('Post', $BlogPost); //This creates new variable $Post which is availible inside templates.
$S->display('Post.html'); //this displays your template
?>
|escape - escapes all html in variable < goes ^lt; etc.
I'm looking for ways to have my pages search for the page layout from an external template page. Please see the below example.
<head>
<title></title>
</head>
<body>
<search for header, css, layout, etc from external page>
Page contents
<search for footer>
</body>
Is there any way to do this using PHP or HTML? I want to be able to edit the layout for all the pages without having to do it page by page. I welcome any other means to achieve the same effect as long as it works on all the browsers.
Thank you very much!
This is exactly the sort of thing that PHP is for. A PHP script can include the contents of another script using the include statement.
So each page in your application could have an associated PHP script that generates the contents, and includes footer.php for the footer layout. In this way, when you change footer.php all the pages that use it will automatically get the changes.
You can't do this with pure HTML, though you could with some javascript and Ajax.
Like Andrew said, use includes. I'll set up 2 basic examples.
The simplest, have multiple layout files that are called by your main file(s):
header.php:
<div id="header">
Menu can go here.
<?php echo 'I make all my files .php, so they can use PHP functions if needed.'; ?>
</div>
footer.php
<div id="footer">
Footer Link
</div>
index.php
<html>
<head></head>
<body>
<?php include('/path/to/header.php'); ?>
Specific index.php content here.
<?php include('/path/to/footer.php'); ?>
</body>
</html>
The other option is to have one PHP file which includes all your different layout elements in functions. The reason I like this, is because you can include one file and then call specific functions for different parts. This can also be used to pass variables like a title of a page.
layout.php
<?php
function makeHeader($title) {
return 'My title is: '.$title;
}
function makeFooter() {
$html = '
<div id="footer">
Footer Link
</div>
';
return $html;
}
?>
index.php
<?php include('/path/to/include.php'); ?>
<html>
<head></head>
<body>
<?php echo makeHeader('Page Title'); ?>
Specific index.php content here.
<?php echo makeFooter(); ?>
</body>
</html>
Just make sure you use relative paths (no http://www.) when including files. This will allow variables and functions to transfer over smoothly. The easiest way to do this is using the PHP variable $_SERVER['DOCUMENT_ROOT'] so if you have a file http://mysite.com/includes/layout.php, you could include it with include($_SERVER['DOCUMENT_ROOT'].'/includes/layout.php') no matter where your file you are including from is located.
Something basic that i don't understand:
I have header.php with navigation bar for my site. Inside it, there's a <head>...</head> section.
Now, in each other page of my site, I'm using require_once 'header.php' so that each page will show the navigation bar. But, I need also specific <head>...</head> sections to the different page.
For example, in page customers.php, I'm using <script>...</script> to include the jQuery library. I don't need to include it in other pages.
Now, searching the web I see that multiple head tags is wrong syntax.
So, how can anyone:
avoid multiple "head" tags
WHILE
separating his work to different PHP files and including them ?
You have to change your page structure and employ templates.
Instead of loading header at the top of the code, you have to do it at the bottom!
And page code should output not a word, but collect all data in variables.
And only after that output can be started by calling template.
A example layout is going to be like this:
First. page itself.
it outputs nothing but only gather required data and calls a template:
<?
//include our settings, connect to database etc.
include dirname($_SERVER['DOCUMENT_ROOT']).'/cfg/settings.php';
//getting required data
$DATA=dbgetarr("SELECT * FROM links");
$pagetitle = "Links to friend sites";
//etc
//and then call a template:
$tpl = "links.php";
include "template.php";
?>
Next, template.php which is your main site template, consists of your header and footer:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>My site. <?=$pagetitle?></title>
</head>
<body>
<div id="page">
<? include $tpl ?>
</div>
</body>
</html>
And, finally, links.php is the actual page template:
<h2><?=$pagetitle?></h2>
<ul>
<? foreach($DATA as $row): ?>
<li><?=$row['name']?></li>
<? endforeach ?>
<ul>
easy, clean and maintainable.
there are many advantages in such approach:
as requested, you can populate header with actual page-relevant data.
HTTP headers can be sent as well, before any output. It includes cookies, sessions, cache-control and many more.
it's 2011 today. AJAX era. You may wish change your code to return JSONed data instead of whole HTML page. It's going to be easy using such layout.
Imagine you're going to create very similar site with just different design. You will have to change only templates and don't touch engine files. That's really great advantage of using templates.
Here are some simple ways you can look at.
You can have jQuery on the pages
that don't need it; once it's
downloaded it will be cached so it
still wont use more bandwidth.
You can move out the closing </head>
tag from header.php and close the
<head> tag in the page that's including
header.php.
You can include javascript anywhere
on a page, not only in the header.
You can also do something like this.
Before you do require_once 'header.php'; you put a variable called $jquery = true;
In your header.php file you check if $jquery is set to true, if it is, you include jQuery.
in header.php
you can type like this
<head>
<?php echo $script; ?>
</head>
then in your customers.php
you can first assign the variable
$script = '<script>...</script>'
then
require_once 'header.php'
One possible solution.
You create a global variable before including header.php.
You test this variable in header.php.
If it is true, You print script or something. Something like this:
<!-- Fragment of header.php -->
<?php if ($i_want_jquery): ?>
<script ...>
...
</script>
<?php endif; ?>
On the other hand, a template may be a better solution.
