                                </select>
                                <input type="text" name="producttype" id="product_hidden">


                            </div>

                            <input type="submit" class="btn green" value="Registration">
                        </form>

<script>
            $(document).ready(function() {
                $("#eproducts").change(function(){
                    $("#product_hidden").val(("#eproducts").find(":selected").text());

                });
            });
        </script>

但是，当我按下提交按钮时，它不发布产品类型或当我更改所选项目时，它在文本框中不显示值。请帮帮我

result = mysql_query（

result = mysql_query(

query）或 die（

query) or die(
