simpler way to find request method

[eluser]zauber[/eluser]
Quick question: is there a CI-built-in method to do: if($_SERVER["REQUEST_METHOD")=="POST"){...}

Not that it's very hard to do, I just couldn't find anything about request-method handling in the docs, and figured there might be something.

you could check for the $_POST global

Code:

isset($_POST)

If you want a CI method you could name your submit or use some input that will always gets posted to check

Code:

!$this->input->post('submitInputName')

Ah, thanks! the $this->input thing I did not know about. I was just pulling things from $_POST directly. But I think that the $_POST array is always set (it's just empty sometimes) so the first alternative doesn't work. The second alternative looks brilliant though.

Another follow up then - now that I know about the input class - does the validation library get the same security filtering on the post-data as you get from input->post()?

If you use validation, the following three will all be equal:

Code:

$_POST['var'];
$this->input->post('var');
$this->validation->var;

Without validation, omit the 3rd line.

Sometimes the $_POST global is set but you can do

Code:

isset($_POST) && count($_POST) > 0

If you mean that the validation uses the global xss filter i don't think so but i'm not sure. But you can add it to the field rules yourself using xss_clean.

The docs say, regarding the input class, that it:

...Filters the POST/COOKIE array keys, permitting only alpha-numeric (and a few other) characters...

On the other hand, no mention of this filtering appears together with the description of the input->post() function, so perhaps it's something that's done at construction time.

I suppose it doesn't matter unless I want to:
foreach($_POST as $key=>$val){...do something irresponsible with $val }

...which I of course wouldn't

I recently put together a request_helper.php file for this which just contains:

Code:

/**
* Return the request type that the user is making
*
* @return string
*/
function request_method()
{
    return strtolower($_SERVER['REQUEST_METHOD']);
} // request_method()



/**
* Is the current request a POST request?
*
* @return bool
*/
function request_is_post()
{
    if (request_method() == 'post') {
        return true;
    }
    return false;
}

I autoload it on all my projects so that in the controller I can just do things like:

Code:

public function edit()
{
    if (request_is_post()) {
        // do save/validation stuff...
    } else {
        // just display the form...
    }
}

hey, ucantblamem - that's a sweet and simple little solution. Being new to the CI-stuff, it's really helpful to get to see ways in which people are tweaking CI to do what they want in elegant ways. Thanks!

Be sure to read the Input Class page in the CI user guide; it explains this and a whole lot more.
