Checking if a request is POST?

[eluser]Unknown[/eluser]
How can I check if a request was submitted with the POST method (does CI offer a shorter way than "if($_SERVER['REQUEST_METHOD'] === 'POST')")?

Code:

$something = $this->input->post('something');

Code:

$something = $this->input->post('something');

That only checks for the existence of $_POST['something'], so it won't work.

I don't believe there is, but you could write a quick helper function that did it for you.

Personally I extend input->post() to, if no argument is given, return TRUE if anything has been posted at all. You might want to do something similar.

How do you override controller methods, preserving the old one? Like in Ruby I'd do

Code:

class Controller
  alias_method :post_orig, :post

  def post *args
    if args.empty?
      # Code to determine if POST
    else
      post_orig args
    end
  end
end

Sorry for the example in another lang, my PHP is rusty.

input->post is not a controller method, but a method of the input library ( http://ellislab.com/codeigniter/user-gui...input.html ).

In CodeIgniter you extend core libraries (such as input) by placing a file called MY_Input.php in your libraries folder, with the following prototype:

Code:

class MY_Input extends CI_Input {

//your extended code here

}

while still calling it with $this->input->post() as you normally would. more on that here: http://ellislab.com/codeigniter/user-gui...asses.html

in your case it would be something alá:

Code:

class MY_Input extends CI_Input {

    function post($index = '', $xss_clean = FALSE)
    {
        // this will be true if post() is called without arguments
        if($index === '')
        {
            return ($_SERVER['REQUEST_METHOD'] === 'POST');
        }
        
        // otherwise do as normally
        return parent::post($index, $xss_clean);
    }
}

thank you very much for this extension,it's more like CI style.

I used to use this:

Code:

if($_POST)
{
   // do something
}
