I am building a Website using Bootstrap 4. The template that I am using has a carousel at the top of the page. I use my index.php page as a shell for other content which is called using the following code:
<?php
if (!isset($_REQUEST['content']))
include("home.php");
else
{
$content = $_REQUEST['content'];
$nextpage = $content;
include($nextpage);
}
?>
Currently the carousel will show on every page. I would like for it to only show on the home page or index.phpcontent=home.php but I have yet to figure out how to do that without breaking things.
On the index.php page I have set up chunks of code to be called with include statements:
<body>
<header>
<?php include 'navbar.php'; ?>
<?php include 'carousel.php'; ?>
</header>
I have tried to programatically simply call the carousel.php as follows:
<?php
if (!isset($_REQUEST['content']))
include("carousel.php");
else
{
include("");
}
?>
But that did not work. Any help would be greatly appreciated.

I am using PHP Codeigniter While I will try to convert pdf for multiple pages, the next page data coming on the first pages. I want to convert pages data page wise. How can I do it?
I have followed this code:
Controller:
<?php
$createPDFFile="myData.pdf";
$data['user_data'] = $returnData;
$htmlContent = $this->load->view('admin/download_user_data', $data, TRUE);
$this->createPDF(FCPATH.'assets/generate_pdf/'.$createPDFFile, $htmlContent);
?>
in View
<?php
if(!empty($user_data)) {
foreach($user_data as $pdata) {
?>
<!-- Here My html Code -->
<?php
}
}
?>
You have to put a break line after page data. I have got the success to added this line below of the last html tag.
<br pagebreak="true"/>
Hope it will be helpful for you.
Currently my site title looks like:
<title>My Site Title</title>
The above code is added on 'header.php' file, so every pages has the same page title.
I need to set different titles for different pages.
for example,
<title>
if 'contact.php' then title= 'Contact Us'
else if 'faq.php' then title= 'FAQ'
else if 'add.php' then title= 'Add'
else title= 'My Site Title'
</title>
somebody please help me!!
I guess contact.php include 'header.php';. Then something like this would work:
contact.php:
<?php
$title = 'Contact Us';
include 'header.php';
// your code
?>
header.php:
<?php
echo '<title>'.$title.'</title>';
Tip: have a look at template engines. I like smarty for example. Maybe someone will comment on this with some other examples ;)
Make a variable in your script called $page and use that variable in the template file.
Business logic for page Home, for example:
<?php
.
.
.
$page = 'Home';
render($page);
View logic page for Home:
.
.
.
<title>
<?php echo $page; ?>
</title>
.
.
.
This is just a concept, it is not a fully functional code.
Split your header in to 2 seperate php files, one before the title, and one after the title (this will work with other page specific data, see note at end of answer)
then the top of your pages should look like:
<?php include_once("inc/begin-head.inc");?>
<title>My Title</title>
<meta name="description" content="description"></meta>
<?php include_once("inc/end-head.inc");?>
There are some other solutions, such as make header a class and define variations to it, and then call a function to output the head completly
Please note, there are a LOT of other paged specific tags. Title, Meta Description, Canonical url link, meta keywords, open graph data .....
You can try like this and use basename($_SERVER['PHP_SELF']) and now lookup for the $title[key]
$title = array();
$title['home.php'] = 'My home page';
$title['Hello.php'] = 'My title';
I'd advice you to use an array with titles instead of a series of ifs (respectively a switch)
<?php
$file = basename($_SERVER['PHP_SELF']);
$titles = array(
'contact.php' => 'Contact Us',
'faq.php' => 'FAQ',
'add.php' => 'Add',
);
if(array_key_exists($file, $titles){
echo '<title>'.$titles[$file].'</title>';
}else{
echo '<title>Ny Site Title</title>';
}
?>
To add title dynamically , first set the following code in header.php file :
<title>
<?php
if(isset($title) && !empty($title)) {
echo $title;
} else {
echo "Default title tag";
}
?>
</title>
and set title in each page before including header as :
$title = "Your Title";
include 'header.php';
How I did this for anyone curious in the future...
I have a "pagetitles.php" page that contains this code:
$page_files=array(
"admin"=>"Admin Panel",
"profile"=>"Your Profile",
"billing"=>"Billing / Subscriptions",
"pricing"=>"Our Pricing",
"settings"=>"Your Settings",
"bugs"=>"Bug/Feature Tracker",
"search"=>"Search Results",
"clients"=>"My Clients");
if(isset($_GET['rq'])){
if(in_array($_GET['rq'],array_keys($page_files))) {
$pagetitle = $page_files[$_GET['rq']];
}
}
Then I include that file at the very top of my index.php page, and echo $pagetitle where I want the title to be. BUT this also requires another file to handle serving the specific pages, using a ?rq request
In my "page_dir.php" file, I have the following that handles ?rq= pages (ex: www.example.com?rq=home will load the home page, with the above page title that's inside of "home" array)
Here's the page_dir.php file:
$page_files=array(
"noaccess"=>"pages/noaccess.php",
"home"=>"pages/dashboard/home.php",
"lists"=>"pages/dashboard/lists.php"
);
if(isset($_GET['rq'])){
if(in_array($_GET['rq'],array_keys($page_files))) {
include $page_files[$_GET['rq']];
}else{
include $page_files['home'];
}}else{
include $page_files['home'];
}
This page_dir.php file, I put on the index page where I want main content to show up at... I then have each individual page with just the content (like home.php file is just home.php content without the navbar and footer)
On my index.php file, where I want the page title, I have this code:
if(isset($code_nav_title)){
echo $code_nav_title;
}elseif(isset($pagetitle)){
echo $pagetitle;
}else{
echo "Default Page Title Here";
}
the $code_nav_title lets me set the page title from form submissions if I want it to say "success" or "failed" :) the "default page title here" lets you set something to automatically show up if everything fails to show (like if you forgot to set the page title)
Hopefully this makes sense! It's saved me sooo many headaches and makes it easy for expansion/changes!
I currently have a header.php page which stores all the styles and positions of my header and layout. I then have a contactus.php page which includes the header.php page.
-----CONTACTUS.PHP:
<?php
include 'header.php'
$classnamehere='"linkStyleTwo"' //Here is where I want to update the value
?>
The main links at the top of my page are styled in a certain way using:
------HEADER.PHP:
<?php
$classnamehere= '"linkStyleOne"' ?>
<a href="http://www.google.com" class= <?php echo $classnamehere ; ?>......
I want to alter the style of the link that the person has clicked, so that it pops out indicating to the person which page they are on. Currently, when I try altering the value of $classnamehere inside of contactus.php (by simply assigning it a new value) to change the class printed inside the <a href> tag, nothing happens. It executes the include command, and outputs the value that was stated inside header.php, ignoring my attempts to change the value on the new page.
Is there any way to change the value within contactus.php only, while still keeping the initial value inside header.php so that all the other pages can still use the 'default' style?
Edit: Inside contactus.php, can I change the value of a variable obtained (included) from header.php without actually 'changing' the global variable?
Looking at your code:
-----CONTACTUS.PHP:
<?php
include 'header.php'
$classnamehere='"linkStyleTwo"' //Here is where I want to update the value
?>
The main links at the top of my page are styled in a certain way using:
------HEADER.PHP:
<?php
$classnamehere= '"linkStyleOne"' ?>
<a href="http://www.google.com" class= <?php echo $classnamehere ; ?>......
your code does the following:
contactus.php is executed.
header.php is included, setting the $classnamehere to
'"linkStyleOne"' and creating the actual link with classname
linkStyleOne.
After that $classnamehere is set to linkStyleTwo
This means that you have to assign classname BEFORE including the header.php.
Instead of including it in contactus.php you could do the logic within header.php:
<?php
if ($currentPage) == 'contact') {
//Set this class when user is on a specific page
$classnamehere='"linkStyleTwo"';
}
else {
$classnamehere= '"linkStyleOne"';
}
?>
and just do this in contactus.php
<?php
$currentPage = 'contact';
include 'header.php'
?>
change this
class= <?php echo '"$classnamehere"' ; ?>.
to
class= "<?php echo $classnamehere ; ?>"
Or use it this way
<?php echo '"', $classnamehere ,'"' ; ?>
Or this way(im not sure this works)
<?php echo '"{$classnamehere}"' ; ?>
If you include code, all variables within included code are global and therefore all chnages are reflected in all parts.
in header.php
$a = 10;
in contactus.php
include "header.php"
$a = 0;
And there is no way of changing $a only inside contactus. All code after $a change will be using the new value.
You can create temporary variable $a_copy inside contactus and then change this variable:
$a_copy = $a;
....class= <?php echo '"$a_copy"'...
You should create a PHP class and include it in your header, or make it your header. Invoke it on the page then assign the value for the class variable which you can then echo a separate class function which uses the variable values you require. I can provide an example if you're unfamiliar with the process.
Header.php simple example:
<?php
class Template
{
private $active_nav;
private __construct()
{
}
public function set_active($page = '') // set page test value
{
$this->active_nav = $page;
}
public function get_active() // return page test value
{
return $this->active_nav;
}
public function nav_links() // this could be changed to return an entire header or part or whatever -- change the scope accordingly
{
// active link CSS is linSktyleOne
$current_page = $this->get_active();
$nav_links = '<ul>';
$nav_links .= '<li>Index</li>';
$nav_links .= '<li>Contact</li>';
$nav_links .= '</ul>';
return $nav_links;
}
}
contact.php simple example:
<?php
require_once('includes/header.php');
$template = new Template;
$template->set_active('contact');
// put all your html or other code here
echo $template->nav_links();
?> <!-- blah blah code finished --> <?
// you can always echo a footer out here through a function in the template as well
index.php simple example:
<?php
require_once('includes/header.php');
$template = new Template;
$template->set_active('index');
// put all your html or other code here
echo $template->nav_links();
?> <!-- blah blah code finished --> <?
// you can always echo a footer out here through a function in the template as well
Does all that help make more sense? You only add 1 line of code to each page, and if you really wanted to get fancy you could remove the set function invocation on each page by using a substring of the$_SERVER['REQUEST_URI'] value for a conditional test and put the condition to set the value in the constructor of the class.
Im developing a website and I am trying to a foreach include for my header which includes my navigation menu (the main topic here).
My code inside the header.php file for the navigation menu is here:
<!-- topmenu -->
<div class="menu-header">
<div class="container">
<ul class="top menu">
<?php
$nav = array("Home","About","Portfolio","Products","Services","Contact");
foreach($nav as $item){
if($item == $title){
echo "<li class='current-menu-ancestor parent'><a href='$item.php'>$item</a></li>";
}else{
echo "<li><a href='$item.php'>$item</a></li>"; }
}
?>
</ul>
</div>
</div>
<!--/ topmenu -->
You may notice that in the code is the condition if($item == $title). In my index.php I have included $title="Home"; which I intended to be taken and used in this if statement.
On my index.php page I have included this with the following code:
<?php
include("header.php");
$title = "Home";
?>
Can anyone tell me where I am going wrong?
Not an answer, but comments aren't suitable for formatted code. You might want to de-duplicate some of your HTML:
$class = '';
if($item == $title) {
$class = ' class"current-menu-ancestor parent"';
}
echo "<li{$class}><a href='$item.php'>$item</a></li>";
Duplicating HTML as you did can lead to maintenance problems later on, if you decide to change something in the menu structure and change only one of the copies of the menu html.
header.php can not look into the future. If you want the variable to be set in the include, you need to set it before:
<?php
$title = "Home";
include("header.php");
?>
So you basically just switched the lines.
Additionally I suggest that you enable error reporting to the highest level when you develop, as it will give you warning on common mistakes that can happen while typing code.
You can do this by adding the following two lines to the top of your script:
error_reporting(~0);
ini_set("display_errors", "1″);
or by changing your PHP configuration.
You need to set $title before including header.php!
i.e.
<?php
$title = "Home";
include("header.php");
?>
I am newbi to wordpress. I have created a website in wordpress which has totally 6 pages.
here 5 pages use the same header, but only one page has different header. So i how can how to create new header.
header.php(is used by all 5 pages): In this case is used "get_header();" in page.php to call the header.
home.php(to be used by home page). here is ther any possible way to access these new header
Please check the link
if link is www.test.com/home.php
then use
<?php if($_SERVER['REQUEST_URI'] == 'home.php') { ?>
<h1>Header for the Homepage</h1>
<?php } else { ?>
<h1>Header for other pages</h1>
<?php } ?>
There's different ways to do this. The easiest would be to use is_home() in header.php to check if the currently loaded page is the homepage. You could change the header.php to something like:
<?php if(is_home()) { ?>
<h1>Header for the Homepage</h1>
<?php } else { ?>
<h1>Header for other pages</h1>
<?php } ?>
