$this->input->get() - what to link to?? - El Forum - 10-19-2010

I am trying to figure out how to use the get in CI.

with regular PHP i would have linked to something like page.php?some_data=value1&some_other_data=valueA

what do i do in CI as there is no *.php in the URL?

If your server is running php as a module in apache, set these in config.php

Code:
$config['uri_protocol']    = "PATH_INFO";

$config['enable_query_strings'] = TRUE;

..thats it! Now you can use for example $this->input->get('some_data') for example:

url: yoursite.com/foo?some_data=value1&some_other_data=valueA

Code:
Class Foo extends Controller {

    function __construct()

    {

        parent::__construct();

    }

    function index()

    {

        echo $this->input->get('some_data').' '.$this->input->get('some_other_data');

    }

}

Thanks, awesome!

So i have some variables being set this way, how do i set a default value for them when there is no input from get??

(Also, i don't really understand how you would use your code?? in the example index would print 'value1 valueA'?? Is this just to show that it worked??)

Yes!
You can set your default values like this:

Code:
Class Foo extends Controller {    

    function __construct(){

        parent::__construct();

    }

    function index(){

        $some_data = (isset($this->input->get('some_data'))?$this->input->get('some_data'):'initial value';

    }

}

This is a shortcut to write if statement.
In my opinion the best way to send parameters to a controller function is to do it codeigniter style, like this.
http://site.com/foo/index/param1/param2

Code:
Class Foo extends Controller {    

    function __construct(){

        parent::__construct();

    }

    function index($param1, $param2){

        echo $param1.' '.$param2;

    }

}

You dont have to use isset() on $this->input->get('something'). It will return FALSE if its not set.

OK so i have the following in a function;

Code:
$var = $this->input->get('url_var'):'5';

and this is giving me a parse error in relation to that line??

I would give you one too...

What are you trying to do here? What does the :'5' do there?

[eluser]umbongo[/eluser]
well.. i am trying to set the default value where there is nothing to 'get'.. so i was trying to set this to '5' in this example.

This is what you need. (:

Code:
$var = ($this->input->get('url_var'))?$this->input->get('url_var'):'5';
