On your controller function

public function edit($record_mpid) {
   $this->load->model('mparam');
   $data['record'] = $this->mparam->getAllRecords($record_mpid);
   $this->load->view('umparam', $data);
}

Then on view

<div class="form-group">
<label class="col-md-4 control-label" for="textinput">Parameter</label>
<div class="col-md-6">
<?php 
$att = array(
    'name' => 'field_name',
    'class' => 'form-control',
    'placeholder' => 'Enter something',
    'value' => set_value('field_name', $record->parameter)
);

echo form_input($att);
?>
</div>
<div class="col-md-6">
<?php echo form_error('field_name', '<p>', '</p>'); ?>
</div>
</div>

Model

public function getAllRecords($record_mpid) {
    $this->db->where('mpid', $record_mpid);
    $query = $this->db->get('mparam');

    if ($query->num_rows() > 0) {
        return $query->row(); // will return single item;    
    }

    return false;

}
