笨發送完整的選擇，而不是從形式

單選項元素這是我的模式下功能..笨發送完整的選擇，而不是從形式

public function get_categories_select() { 
    // output 
    $output = ""; 

    // query 
    $this->db->select("*"); 
    $this->db->from("categories"); 
    $query = $this->db->get(); 

    // zero result(s) 
    if ($query->num_rows() == 0) { 
     return $output = "No Results Found"; 
    } 

    // result(s) 
    $output .= "<select name=\"category\">"; 
    foreach ($query->result_array() as $row) { 
     $output .= "<option value=\"{$row['name']}\">{$row['name']}</option>\n"; 
    } 
    $output .= "</select>"; 

    // return 
    return $output; 
}

這是我的控制器..

public function add_cellphone() { 
    // loading 
    $this->load->model("category_model"); 
    $this->load->model("brand_model"); 
    // controlling 
    $data['categories'] = $this->category_model->get_categories_select(); 
    $data['brands']  = $this->brand_model->get_brands_select("cell phones"); 
    if ($this->validate_cellphone() === FALSE) { 
     // on failure 
     $to_view = "add_cellphone"; 
    } else { 
     // on success 
     $data['category'] = set_value('category'); 
     $data['brand'] = set_value('brand'); 
     $data['model'] = set_value("model"); 
     $data['price'] = set_value("price"); 

     $this->load->model("product_model"); 
     $this->product_model->add_product($data); 
     $to_view = "add_cellphone_success"; 
    } 
    // viewing 
    $this->load->view("admin/templates/header"); 
    $this->load->view("admin/pages/{$to_view}", $data); 
    $this->load->view("admin/templates/footer"); 
} 

public function validate_cellphone() { 
    // laoding 
    $this->load->helper("form"); 
    $this->load->library("form_validation"); 
    // validation rules 
    $config = array(
      array(
       "field" => "category", 
       "label" => "Category", 
       "rules" => "required", 
      ), 
      array(
       "field" => "brand", 
       "label" => "Brand", 
       "rules" => "required", 
      ), 
      array(
       "field" => "model", 
       "label" => "Model", 
       "rules" => "required", 
      ), 
      array(
       "field" => "price", 
       "label" => "Price", 
       "rules" => "required", 
      ), 
      array(
       "field" => "released", 
       "label" => "Released", 
       "rules" => "required", 
      ), 
      array(
       "field" => "status",  
       "label" => "Status",  
       "rules" => "required", 
      ) 
     ); 
    // controlling 
    $this->form_validation->set_rules($config); 
    $this->form_validation->set_error_delimiters('<span class="error">', '</span>'); 
    if ($this->form_validation->run() === FALSE) { 
     return FALSE; 
    } 
    else { 
     return TRUE; 
    } 
    // no viewing 
}

這裏$data['cartegory'] and $data['brand']包含了完整的選擇元素與子選項元素，而不是隻有從窗體視圖中選擇的選項元素。我做錯了什麼？

表單是否通過驗證？ – Jeemusu 2013-04-10 04:10:05

'set_value'只能在你的視圖中使用，設置''字段的'value =「」'屬性。正如fembb在他的回答中所說的，您需要使用'$ this-> input-> post（'category'）;'從控制器的表單中獲取發佈數據。 – Jeemusu 2013-04-11 05:12:24

你想做什麼？對不起，我不明白。如果您的add_cellphone函數在驗證後嘗試獲取數據，我們應該使用$this->input->post("name")來獲取數據，不是嗎？ set_value用於什麼？
