Navigation links using php variables - help wanted

chinrub

As the title reads, I am basically trying to create some sort of navigation system using php variables.

First of all i have created a template file which acts as the empty page to have new content filled into it. It is a pretty standard html page really and I've created images to be used as links. In an area below is space for content to be added.

currently in this area I am using the following code to insert the new content;

template.php

 <?php include $content; ?>

My index page contains this code;

index.php

<?php

$content = 'main.php';

$pageTitle = 'Home';
require_once 'include/template.php';


?>

and so using this I have a working index page.

On to the problem:
My template file contains the images in a sort of navigation bar. I am wondering what is required to allow $content to be changed on the click of one of these images.

Currently i have tried using

<a href="index.php?content=newpage.php">

where "newpage.php" is already created and sat on the server.
However using this appears to have no effect as clicking the link seems to just refresh the page while changing the url in the address bar to what i would expect.

Any advice would be greatly appreciated and thanks for taking the time to read this 🙂

are you talking about something like this?
in order for you to actually see or make a change with your info in the url you actually have to get it from the url...ie. $_GET[''];

and then from there you can do with it what you want 😉

<?
if(isset($_GET['content'])){
 $content = $_GET['content'];
 include(''.$content.'');
}else if(!isset($_GET['content'])){
$content = 'main.php';

$pageTitle = 'Home';
require_once 'include/template.php';
}

?>

thanks for the response
i thought that the URL ?content=newpage.php would actually change the value of the variable. Now i see what the get method would be used for.
Unfortunately i have to go work now so i'll have another look later.

On another not would i be wrong putting that into every page ive created?

if(isset($_GET['content'])){
$content = $_GET['content'];
include(''.$content.'');
}else if(!isset($_GET['content'])){
$content = 'main.php';

and in the template file is it correct to use

<?php include $content; ?>

as i understand that $content will have the value of the $_get passed to it each time a link is clicked?

Stryker250

yes that would be correct...but you will have to include your template file after that if statement so that you have your content page in the content variable

thanks a million mate i have it working
although it seems to work with me just using the code in the template file and the index file
i suppose it might have something to do with me using

<a href="template.php?content=newpage.php">

where template contains the code and is parsed whenever a link is clicked

heh i dunno im confusing myself

it works im happy

now i can say goodbye to linking to seperate files that contain just

<?php
$content = 'bio.php';
require_once 'include/template.php';
?>
