Routing in CodeIgniter

 

contain 

 done URL routing

          from controller

          from view

in controller

          from function and function with parameters

             (missing parameter)

in view

          creating a variable and passing it into the controller

 URL routing 

1 from controller

consider the hello.php file and it must be in controller folder in codeigniter and created public function first with two parameters $p1,$p2 

after modification call the URL path as  localhost/ci/index.php/hello/fist/one/two then result would be shown as 

   my parameter are : one and two

 after calling two parameter inside URL one parameter assign it self in parameter and other called by URL

 then again call URL with one function  localhost/ci/index.php/hello/fist/one out put become

 my parameter are : one and two

again called  index function in same hello.php as special cases

                        

with calling class name localhost/ci/index.php/hello then out put become 

  this is special method

 

  check about the situation about missing parameter in URL statement then call the URL with non parameter as
    localhost/ci/index.php/hello/fist 

 consider we created php file in view named as first.php

 

 then if we want route in view we have to create function in hello.php

public function first($value)
    {
        $data =array("name" => $value);
        $this ->load ->view('first',$data);
    }

 

here we parse the values from hello.php to first.php in view.

http://localhost/codi/index.php/hello/first/jack


then output will be
this is the first in view
                                                                     hello,jack

thank you
