如何检索所选值以便将其更改为另一个？

Question

我希望一旦用户想要编辑组合显示其值而不是选择提供者，但是如果我打开组合框然后显示所有记录以将其更改为其他...

我的html看起来像这样

<div class="col-md-8">
    <label for="provider">Provider: </label>
    <select name="select_provider" id="select_provider" class="form-control" required>
        <option value="">Select a provider</option>
       <?php foreach ($data as $value): ?>
            <option value="<?php echo $value['id']; ?>">
                <?php echo $value['first_name'].' '.$value['last_name'] ?>
            </option>
            <?php endforeach ?>
    </select>
</div>

模型

public function get_product($id) {
        $this->db->select('code,description,purchase_price,sale_price,wholesale_price,min_stock,stock,max_stock,provider_id');
        $this->db->from('storelte_products');
        $this->db->where('hash_id', $id);
        $query = $this->db->get();
        return $query->row();
    }

controller view_update

public function getViewProductUpdate($id){
    $data['data'] = $this->providers->datatable();
    $data['product'] = $this->products->get_product($id);
    $this->load->view('inventory/get_view_product_update', $data);
}
