inserting selected option from dropdown into db codeigniter - php

Question

I have been working on a registration form which has a dropdown list populated from an associative array like this:
**<?php
**$options = array(
'cbaringo' => 'Baringo',
'cbomet' => 'Bomet',
'cbungoma' => 'Bungoma',
'cbusia' => 'Busia',
'celgeyo' => 'Elgeyo Marakwet',
'cmigori' => 'Migori',**
?>**
I want to insert the option the user selects into a database as follows
**$data = array(
'scounty' => $this->input->post('counties'),
'ssubcounty' => $this->input->post('subcounty'),
'sname' => $this->input->post('dschoolname'),
'skcpecode' => $this->input->post('dkcpecode'),
'stelno' => $this->input->post('dtelno'),
'steampatronname' => $this->input->post('dpatroname'),
'steampatronemail' => $this->input->post('dpatronemail'),
'steampatrontelno' => $this->input->post('dpatrontelno'),
's_password' => $this->input->post('scpassword')
);**
pupulated the dropdown like this:
**echo form_dropdown('counties', $options, 'cdefault');**
The above line displays the options on the dropdown list as expected
//inserted data into db
**$this->my_model->insert_data($data);**
however on inserting the key instead of value from the associative array is inserted into db. Whats the problem?

Answer 1

what you see in a select list is different then the value that is passed from it
$options =
// the value // what the user sees in the drop down
array(
'cbaringo' => 'Baringo',
'cbomet' => 'Bomet',
'cbungoma' => 'Bungoma',
'cbusia' => 'Busia',
'celgeyo' => 'Elgeyo Marakwet',
'cmigori' => 'Migori',**
?>
so if they choose Baringo, the value passed should be cbaringo
