将值从jquery传递到PHP而不提交页面 [英] Passing value from jquery to PHP without submitting page

问题描述

在餐厅网站工作。我想给顾客选择食品，因为他们可以修改他们的餐饮订单，我使用jquery将选择价值传递给隐藏领域的餐饮订单。但是餐饮订单上没有显示该值！如何将值从jquery传递给php？



我尝试过：

working on restaurant webiste. and i wanted to give choice for the food item to the customer as they can modify their catering order,i have use jquery to pass choice value to catering order form by hidden field. but that value doesn't displayed on catering order form! how to pass value from jquery to php ?

What I have tried:

<!-- choice -->
					<div class="label_input_group">
						<!--<div class="col-md-3">-->
						<label class="pull-left row hidden"><?php echo $lang['cp_order_choice']; ???></label>
						
						<input type="text" class="hidden col-md-3  list_of_choice form-control" id="order_choice" name="order_choice" value="aaa"/>
						<!--<div class="menuitemids goeshere row">-->
								<div class="cart_choice_goes_up"></div>
					 <!-- </div>-->
						<!--</div>-->
					</div>
					<!-- size -->
						<div class="label_input_group">
						<!--<div class="col-md-2">-->
							<label class="pull-left row hidden"><?php echo $lang['cp_order_size']; ???></label>
							<input  type="text" class="hidden col-md-2 list_of_size form-control" id="order_size" name="order_size" value=""/>
							<div class="cart_size_goes_up"></div>
						<!--</div>-->
					</div>

php

<div class="move_menu_item_inputs">
					
					<input class=" choice" type="hidden" name="menu_item_choice" value="<?php echo $result3['menu_item_choice']; ???>"/>
						<input class=" size" type="hidden" name="menu_item_size" value="<?php echo $result3['menu_item_size']; ???>"/>
						<input class="single_menu_item" type="hidden" name="menu_item_id[]" value="<?php echo $result3['menu_item_id']; ???>" />
						
						<input disabled="disabled" class="single_menu_item menu_item_price_per_slice" type="hidden" name="menu_item_price_per_slice[]" value="<?php echo $result3['menu_item_price_per_slice']; ???>" />
						<input class="single_menu_item item_name col-md-8 form-control" readonly="readonly"  type="text" name="menu_item_name[]" value="<?php echo $result3['menu_item_name']; ???>" />
						<input class="single_menu_item temporary_price_foreach_product" type="hidden" value="" />
						<button aria-hidden="true" class="form-control remove-product-from-cart single_menu_item" type="button">×</button>

						<div class="single_menu_item col-md-2">
						    <input type="text" value="1" class="pull-left row plus-minus-qty form-control" name="plus_minus_qty[]" />
						</div>
					</div>
