Here is my model---
function getebit()
{
$industry=$this->uri->segment(3);
$sql = $this->db->query('SELECT * FROM industry WHERE id='.$industry);
$result = $sql->result();
$html='';
foreach ($result as $data) {
$html.= "<option value='" . $data->ebit . "' >" . $data->ebit . "</option>";
}
echo $html;
}
}
and here is my controller--
function getebitvalue(){
$data['ebit']= $this->site_model->getebit();
}

Answer 1

Method getebitvalue in controller should be like this :
function getebitvalue()
{
$industry_id = $this->uri->segment(3);
$result = $this->site_model->getebit($industry_id);
$html='';
if ( !empty($result)){
foreach ($result as $item)
{
$edita[$key] = $item->edita;
$html.= "<option value='" . $item->ebit . "' >" . $item->ebit . "</option>";
}
$data['edita'] = $edita;
$data['html'] = $html;
print_r($data);
exit;
}
}
Here is your model---
function getebit($industry_id)
{
$sql = $this->db->query('SELECT * FROM industry WHERE id='.$industry);
$result = $sql->result();
return $result;
}

You can also do this-
view page-
<div class="form-group">
<label>Select Type of Industry</label>
<select class="form-control industryData" name="industry" id="industry" required="">
<option value="">------------------Select Your Industry----------------</option>
<?php
foreach ($industry as $value) { ?>
<option data1="<?php echo $value['ebitda']; ?>" data2="<?php echo $value['ebit']; ?>" value="<?= $value['id']; ?>"> <?= $value['industory']; ?></option>
<?php } ?>
</select>
</div>
model page-
function select($tbl,$con=''){
$this->db->select("*");
$this->db->from($tbl);
if(!empty($con))
$this->db->where($con);
$query = $this->db->get();
return $query->result();
}
controller page-
public function dive(){
$this->load->view('common/header');
$data['industry'] = $this->site_model->select('industry');
$this->load->view('dive/dive',$data);
$this->load->view('common/footer');
}
Now use jquery on your view page--
<script>
$(document).on("change", ".industryData", function () {
var value = $(this).val();
var data1 = $('.industryData option:selected ').attr('data1');
var data2 = $('.industryData option:selected ').attr('data2');
alert(data1);
});
</script>
