Retrieve specific column from database and display on screen using CodeIgniter - forms

Question

I have a database table called input_types with a various input types:
[id] [input_type_Name]
1 text
2 radio
3 checkbox
4 select
... ...
I want to retrieve the names from the table and put them in an array so that I can then use form_dropdown to show them to the user in a dropdown.
The problem with how I'm doing it now is that I create optiongroups.
How I do it now:
Model
function get_inputTypes() {
$this->db->select('input_type_name');
$query = $this->db->get('input_types');
if($query->num_rows() > 0) {
return $query->result_array();
}
else {
return false;
}
}
Controller
$results = $this->survey_model->get_inputTypes();
$data['inputTypes'] = $results;
View
<label for="inputType">Input type:</label>
<?php echo form_dropdown('inputType', $inputTypes); ?>
This however doesn't create the desired effect. My dropdown gets populated, but because I have a multidimensional array the dropdown has optgroups.
I just want to have my selected data in a simple array. Why is this so freaking hard in CodeIgniter and php in general.
C# is much easier :/
Solution
The solution is very simple, use a foreach to loop through the multidimensional array in the model:
foreach($query->result() as $input_type) {
$data[] = $input_type->input_type_name;
}
return $data;

Answer 1

What do you mean by "This however doesn't create the desired effect" ?
Make sure you pass the $data to your view:
$this->load->view('viewname', $data);

Answer 2

The solution is very simple, use a foreach to loop through the multidimensional array in the model:
foreach($query->result() as $input_type) {
$data[] = $input_type->input_type_name;
}
return $data;
