Retrieve selected value from dropdown form populated from DB. Jquery
#1

Hi there, have been working on this problem far too long so have signed up for some help.

I am trying to create a dropdown form with countries populated from a database. I need to get the chosen countries ID and store it into another table on the DB. So far i have created the dropdown but have no idea how to use JQuery to get ID from the list.

Any help would be appreciated.

VIEW:

<?php
$attributes = array('class' => 'profile_textbox_disabled', 'id'=> 'country_select', 'disabled' =>'disabled');
echo form_open('', $attributes);
echo form_dropdown('countries', $select_country);
?>
<a href="#" id="country_select_edit"><img src="&lt;?php echo base_url(); ?&gt;assets/images/edit.png" alt="Edit" ></a>
<span id="country_select_ajax_reply" class="notify"></span>
&lt;?php
echo form_close();
?&gt;

JQuery:

$("#country_select_edit").click(function () {
$('#country_select').addClass('profile_textbox_enabled').removeAttr("disabled")
.change(function () {

$.ajax({
type: "POST",
url: "calls/countries_list/",
//data: "data=" + $(this).val(), //These are other methods i've tried.
//data: "country_name="+$('#country_select').val(), //These are other methods i've tried.
data: "country_name="+this.value+"&id;="+&lt;?php echo $this->session->userdata('user_id'); ?&gt;,
complete: function(data){

//print result in targetDiv
$('#country_select_ajax_reply').html(data.responseText);
}
});

$('#country_select').removeClass('profile_textbox_enabled').attr("disabled", "disabled");

});
});


MODEL:

$query = $this->db->query("
SELECT country_id, country_name
FROM countries
");
foreach($query->result_array() as $row)
{
$data[$row['country_id']]=$row['country_name'];
}
return $data;

CONTROLLER (for JQuery)

function countries_list()
{
$message = $_POST['country_name'];
//echo $_POST['data'];
echo $message;
}

Am using $message to trial and error the code to try get a value returned. At the moment i keep getting undifined.
