codeigniter checkbox array handling issue

I have form fields which are checkboxes as below :

<input id="[email protected]" type="checkbox" checked="checked" value="[email protected]" style="float:left;border:2px dotted #00f" name="email[]">
<input id="[email protected]" type="checkbox" checked="checked" value="[email protected]" style="float:left;border:2px dotted #00f" name="email[]">
<input id="[email protected]" type="checkbox" checked="checked" value="[email protected]" style="float:left;border:2px dotted #00f" name="email[]">

But when in the controller I am taking a var_dump($this->input->post('email')) , it displays bool(false) .

in the controller I have this method :

public function referral_email()
{
    $data = $this->input->post('email');
    var_dump($data);exit;
 }

How to access this array of checkboxes in my controller ?

trim() works on strings, but your $_POST['email'] is an array. The correct fix should be to pass the field name as 'email[]' when using the form validation library (in the code you didn't show us but commented on later).

Are you by any chance trying to trim the output using the form validation library? I had the same problem, and removing 'trim' from the validation rules solved it.

Make sure the form tag surrounding the text boxes has the attribute method="post" or else it might be submitting to the $_GET array. I got it to work with the following code:

Controller

public function referral_email()
{
    $data = $this->input->post('email');
    var_dump($data);
}

View

<form method="post" action="welcome/referral_email">
<input id="[email protected]" type="checkbox" checked="checked" value="[email protected]" style="float:left;border:2px dotted #00f" name="email[]">
<input id="[email protected]" type="checkbox" checked="checked" value="[email protected]" style="float:left;border:2px dotted #00f" name="email[]">
<input id="[email protected]" type="checkbox" checked="checked" value="[email protected]" style="float:left;border:2px dotted #00f" name="email[]">
<input type="submit" value="Submit" />
</form>
