processing $_POST in codeigniter

问题:

How do i do this in codeigniter?

$cuisineArr = isset($_POST['cuisine']) ? $_POST['cuisine'] : array();

I read somewhere that using $_Post[''] direct is a not the right way and post() should be used instead. But how do i do the same in codeigniter?

I'm getting an array from a group of checkbox, then converting it to csv. The non-codeigniter code is below:

$cuisineArr = isset($_POST['cuisine']) ? $_POST['cuisine'] : array();
$cuisineArrCSV = implode(',',$cuisineArr);
echo $cuisineArrCSV;

You need to use the CodeIgniter Input class.

Here's what your code should look like:

$cuisine = $this->input->post('cuisine');
$cuisineArr = ($cuisine != FALSE) ? $cuisine : array();
$cuisineArrCSV = implode(',',$cuisineArr);
echo $cuisineArrCSV; 

回答2:

$cuisineArr = ($this->input->post("cuisine") != false) ? $this->input->post("cuisine") : array();

Should do the trick.

Make sure the class input and post CodeIgniter there

if ($this->input->post())
