Load different data depending on URL? - El Forum - 10-23-2010
[eluser]invision[/eluser]
Hi,
I have a URL: http://www.site.com/index.php/scotland/glasgow/hotels/
I want to do different things depending on what part of the URL the user is visiting.
E.g. if they're on /index.php/scotland/ it'd show different data than when on the full URL above.
How do I achieve this with CodeIgniter?
On a previous thread, I got as far as the following...but it didn't work
I tried to take in the three different parts of the URLs as parameters ($param_1 etc...)
Controller:
Code:
function index($param_1 = FALSE, $param_2 = FALSE, $param_3 = FALSE) {
//check params to see which are set and act accordingly
// retrieves country
if (($param_1 !== FALSE) && ($param_2 === FALSE) && ($param_3 === FALSE)) {
$data['entries'] = $this->Mains->get_entries($param_1);
$data['title'] = 'country';
$data['main'] = 'public_page';
$this->load->vars($data);
$this->load->view('template');
}
// retrieves city
if (($param_1 !== FALSE) && ($param_2 !== FALSE) && ($param_3 == FALSE)) {
$data['entries'] = $this->Mains->get_entries($param_1, $param_2);
$data['title'] = 'city';
$data['main'] = 'public_page';
$this->load->vars($data);
$this->load->view('template');
}
// retrieves category
if (($param_1 != FALSE) && ($param_2 != FALSE) && ($param_3 != FALSE)) {
$data['entries'] = $this->Mains->get_entries($param_1, $param_2, $param_3);
$data['title'] = 'category';
$data['main'] = 'public_page';
$this->load->vars($data);
$this->load->view('template');
}
// no specific category chosen
if (($param_1 == FALSE) && ($param_2 == FALSE) && ($param_3 == FALSE)) {
$data['entries'] = $this->Mains->get_entries($param_1, $param_2, $param_3);
$data['title'] = 'no specific category chosen';
$data['main'] = 'public_page';
$this->load->vars($data);
$this->load->view('template');
}
}-
-
For reference my Model is:
Code:
<?php
class Mains extends Model {
function Mains() {
parent::Model();
}
function get_entries($country = FALSE, $city = FALSE, $category = FALSE) {
$this->db->select('entry.*, city.title as city_title, country.iso3 as country_title, category.title as category_title');
$this->db->from('entry');
$this->db->join('category', 'entry.category = category.id');
$this->db->join('city', 'entry.city = city.id');
$this->db->join('country', 'city.country = country.iso3');
if($country !== FALSE) {
$this->db->where('country.iso3', $country);
}
if($city!== FALSE) {
$this->db->where('city.title', $city);
}
if($category!== FALSE) {
$this->db->where('category.title', $category);
}
$result = $this->db->get();
if($result->num_rows() > 0) {
return $result->result_array();
} else {
return FALSE;
}
}
function get_cities($country) {
$this->db->from('city');
$this->db->join('country', 'city,country = country.iso3');
$this->db->where('country.iso3', $country);
$result = $this->db->get();
if($result->num_rows() > 0) {
return $result->result_array();
} else {
return FALSE;
}
}
}
?>I would massively appreciate any guidance with this.
Many thanks.

Use a different way of processing the parameters:
Code:
if ( $param_1 === FALSE )
{
// no parameters given at all
}
else
{
if ( $param_2 === FALSE )
{
// load full country information
}
else
{
// load limited country information
if ( $param_3 === FALSE )
{
// load full city information
}
else
{
// load limited city information
// load the category information
}
}

Aaaaaaah, now that sounds sensible
I'll give it a try and report back post haste.

I've given this a shot, but it displays 'country' no matter what part of the URL I'm at
I just need to show Country data if the URL is at: http://localhost/ae/index.php/gbr/
City data if the URL is at: http://localhost/ae/index.php/gbr/glasgow/
Category data if the URL is at: http://localhost/ae/index.php/gbr/glasgow/hotels/
Thanks again for any advice.

My Controller code:
Code:
<?php
class Main extends Controller {
function Main(){
parent::Controller();
session_start();

function index($param_1 = FALSE, $param_2 = FALSE, $param_3 = FALSE) {
//check params to see which are set and act accordingly
if ( $param_1 === FALSE )
{
// no parameters given at all
}
else
{
if ( $param_2 === FALSE )
{
// load full country information
$data['entries'] = $this->Mains->get_entries($param_1);
$data['title'] = 'country';
$data['main'] = 'public_news';
$this->load->vars($data);
$this->load->view('template');
}
else
{
// load limited country information
if ( $param_3 === FALSE )
{
// load full city information
$data['entries'] = $this->Mains->get_entries($param_1, $param_2);
$data['title'] = 'city';
$data['main'] = 'public_page';

$this->load->view('template');

$this->load->view('template');
}
}
}
}

Ok, then I misunderstood the question. But indeed, if you leave out the 'limited' parts like in your last post, it should work the way you want.

Thanks for the reply.
It still doesn't seem to work when I use the code in my last post.
It still displays 'Country' even when I'm down at the 'City' or 'Category' part of the site.
Is there a better way of doing this that you know of?
Really appreciate the help.

Reverse the check... check for the third parameter FIRST... if it exists, display the info. If it doesn't, then check the second... if it exists, display the info... if it doesn't then check the first... and so on.

Thanks for the reply TG.
Can you explain what you mean using my code from post #4.
I've tried reversing it at my end, but it's not quite working.
Thanks again

See if this works:
Code:
<?php
if ($param3 === FALSE)
{
// If there is no Paramer 3... check #2
if ($param2 === FALSE)
{
// If there is no Parameter 2... check #1
if($param1 === FALSE)
{
// No parameters given
} else {
// Load Country info
$data['entries'] = $this->Mains->get_entries($param_1);
$data['title'] = 'country';
$data['main'] = 'public_news';
$this->load->vars($data);
$this->load->view('template');
}
} else {
// Load city information
$data['entries'] = $this->Mains->get_entries($param_1, $param_2);
$data['title'] = 'city';
$data['main'] = 'public_page';
$this->load->vars($data);
$this->load->view('template');
}
} else {
// Load Category information
$data['entries'] = $this->Mains->get_entries($param_1, $param_2, $param_3);
$data['title'] = 'category';
$data['main'] = 'public_page';
$this->load->vars($data);
$this->load->view('template');
