Answer 1

Try this code ,It is working .
<script type="text/javascript">
function getSummary(id)
{
$.post("<?php echo site_url('ajax_controller/getBranchDetails'); ?>",
{branch_id:id},function(data,status){
$('#summary').html(data);
});
}
</script>
Note : Check whether you have included jquery.min.js . If not mention the below code in view part header
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js">

Try this instead:
<script type="text/javascript">
function getSummary(id) {
$.ajax({
type: 'POST',
url: "<?php echo site_url('ajax_controller/getBranchDetails'); ?>", // <-- properly quote this line
cache: false,
data: {branch_id: id}, // <-- provide the branch_id so it will be used as $_POST['branch_id']
dataType: 'JSON', // <-- add json datatype
success: function(data) {
// if you need to present this in a html table,
// likely, you need to use $.each() and build the markup using the json response
$('#summary').html(data);
}
});
}
</script>
Model: (Don't directly use variables inside the query string)
$sql = 'SELECT * FROM companydetails WHERE id = ?';
$query = $this->db->query($sql, array($id));
Controller:
public function getBranchDetails()
{
$b_id = $this->input->post('branch_id', true);
$this->load->model('ajax_model');
$data['results'] = $this->ajax_model->getRecords($b_id);
echo json_encode($data); // <-- uncomment
}
