如何避免在URL中传递参数

Question

Hi professionals have a good day.

I am new to this Codeigniter framework.

Question 1: how to avoid passing argument in url or is there any other option like using dummy value or default value instead of passing original value?

Example : Currently i have like this

http://localhost/manage?keyword1=SAP&keyword2=LAB

but i want it to be like this

http://localhost/manage?keyword1=XXX&keyword2=YYY

Question 2: i have seen some example, in that they are using remap function to accomplish this task but i didnt get how remap work . is this right way do to?

please give your suggestion and tell me the right way and sorry it may be a silly question but i searched lot i didnt anything . thanks in advance

Answer 1

in Codeignitor you have to pass like this http://localhost/manage/controller/method/xxx/yyy

then in controller

function method ( $x , $y )
{
  echo $x;
  echo $y;
}

Answer 2

function somefunction ($param1 = null, $param2 = null)
{



}

if the params are not passed, then it will have the default values null , but if the arguments are passed then you could handle them like this:

function somefunction ($param1 = null, $param2 = null)
{
   $param1 = intval($param1) //if you want it to be int
   $param2 = floatval($param2) //if you want it to be float


}

if you want to change the parameters visually in the browser, then just redirect it like this:

function somefunction ($param1 = null, $param2 = null)
{
   if($param1 == null || $param2 == null)
  {
      $param1 = 'XXX'; //put any value you want by your logic
      $param2 = 'YYY'; //put any value you want by your logic
      header("Location: http://localhost/manager/somefunction/".$param1.'/'.$param2);
  }


}

In codeigniter, there is a library called 'session'. In this library there is a functionality called flashdata. This acts just like a $_POST method, however it does not require a form.

Example: To set a variable in flashdata:

$this->session->set_flashdata('example', $variable1);

'example' is the name of your flashdata and $variable is what it's storing.

To access your data on the next page:

$variable2 = $this->session->flashdata('example');

$variable2 will then equal whatever you set $variable1 as in the previous page.

Hope this helps! Just an alternative to passing an argument through the URL.
