Get post values when the key is unknown in CodeIgniter

Question

CodeIgniter allows access to POSTed data via:

$this->input->post('input_name');

where 'input_name' is the name of a form field. This works well for a static form where each input name in known ahead of time.

In my case, I am loading a collection of key/value pairs from the database. The form contains a text input for each key/value pair.

I am wondering, is there a way to get an array of posted data via the CodeIgniter api?

Thanks!

Answer 1

foreach($this->input->post() as $key => $val)  {  echo "<p>Key: ".$key. " Value:" . $val . "</p>\n";  } 

that can be used to

Answer 2

According to the documentation, no. I would suggest just using array_keys($_POST) to get the keys.

Answer 3

Surely if you have an array of keys from the database you can use that, like :

foreach ($arrayFromDb as $key => $value) {
    $newValue = $this->input->post($key);
}

Then you have the advantage that people if people submit additional fields (e.g. by modifying the form and posting it themselves) those fields will be ignored
