Helo,
I have a confussion and I need to get it solved in core php we used to create a url parameter through which we would be able to get values from the url so hwo this could be happend in codigniter for example
<a href="index.php?add=1">Add page</a>
//setting up a get request
if(isset($_GET["add"]) == 1) {
//show ad page form
} else {
//show the whole page
}
how do this same condition would be done in codigniter?
Jump to PostYou have to assign a value to
parameter:<?php echo anchor('admin/pages?parameter=value', 'Click Here'); ?>Otherwise the IF condition fails, try:
var_dump($this->input->get('parameter'));

Your view file and Controller function goes like below
<html> <head></head> <body> <div id="container"> <a href="index.php?add=1">Add page</a> </div> </body> </html> class Welcome extends CI_Controller { public function index(){ $add=(int) $this->input->get('add'); if(isset($add) && $add === 1) { echo "show ad page form"; } else { echo "show …
You can append the query string to the link and then access it through $_GET as in pure PHP or by using $this->input->get('keyword').
For example, you have controller Blog with method show($title_slug) and you want to append a query string to show the comments, your link would look like:
http://website.tld/blog/show/hello-world-title?comments=on
in controller:
class Blog extends CI_Controller
{
public function __construct()
{
parent::__construct();
}
public function show($title)
{
$comments = $this->input->get('comments');
# other code ...
}
}
$this->input->get(),
This method will return all get parameters,you need to set your variable name and get value.
I tried like this in the view file as i want to set condition there
<?php
if($this->input->get('parameter')) {
echo 'Parameter condition is running okay';
}
echo $this->input->get('parameter');
?>
<?php echo anchor('admin/pages?parameter', 'Click Here'); ?>
But nothing happend for me though please let me know what I am ding wrong

<a href="index.php?add=1">Add page</a>
</div>

</html>
class Welcome extends CI_Controller {
public function index(){
$add=(int) $this->input->get('add');
if(isset($add) && $add === 1) {
echo "show ad page form";
} else {
echo "show the whole page";
}
}
}
Now if you type "localhost/CodeIgniter_2.1.4" . it will show you "show the whole page" and if you call "localhost/CI2.1.4/?add=1" it will show you "show ad page form"
i think passing condition directly in view is not good so you can go like below.
class Welcome extends CI_Controller {
public function index(){
//setting up a get request
$add=(int) $this->input->get('add');
$data['add']=$add;
$this->load->view('welcome_message',$data);
}
}
