Answer 1

<input type="checkbox" name="businessType[]" value="1">
<input type="checkbox" name="businessType[]" value="2">
<input type="checkbox" name="businessType[]" value="3">

do $data = $this->input->post('businessType');

You should see that $data is an array, and shows different values. Try doing var_dump($data); to see what's inside the array.

var_dump()

Answer 2

Put braces after each name. Give each a unique value:

<input type="radio" name="businessType[]" value="1">
<input type="radio" name="businessType[]" value="2">
<input type="radio" name="businessType[]" value="3">

Get them like this:

substr(implode(', ', $this->input->post('businessType')), 0)

Answer 3

If only one of these checkboxes can be selected at a time, you should use a group of radio buttons (type="radio") instead. I assume this is what you are trying to do since the names of all of the inputs are the same.

To get the value of the checkbox or radio button group, use:

$this->input->post('businessType')

Edit:

If you are actually wanting checkboxes, you will need to name them all something different:

<input type="checkbox"name="businessType1" value="1">
<input type="checkbox"name="businessType2" value="2">
<input type="checkbox"name="businessType3" value="3">

And then use the same post method as before:

$this->input->post('businessType1') //the first checkbox's value
$this->input->post('businessType2') //the second
$this->input->post('businessType3') //the third
