我正在为一个酒吧申请。
当文档准备好时，应用程序通过执行get_beers_from_customer();来用"啤酒表单按钮"填充#beer_output。然后，调酒师通过点击"啤酒表格按钮"来提供饮料。
每次酒保点击"啤酒表单按钮"时，都会发出一个ajax调用，并将其发送到codeigniter控制器，在那里删除啤酒，并用剩下的啤酒回复ajax，直到没有剩下的订单了。
一旦没有啤酒了，订单就会通过我的控制器的另一个功能process_order_when_all_drinks_served($user_id)进行处理。
我使用authorize.net作为支付网关。
问题是，当我只点了一杯啤酒，但如果我点了两杯啤酒，一切都很好。process_order_when_all_drinks_served($user_id)输出错误尝试获取非对象的属性。
这里是错误发生的具体位置if($response->response_code=="1")，显然它没有给出响应。ajax正在发布，并且没有返回任何错误。我不知道发生了什么。如果有帮助的话，我可以给你链接并点一杯饮料。
以下是ajax函数
$(document).ready(function(){
get_beers_from_customer();
function get_beers_from_customer()
{
//form variables
var user_id = "<?php echo $this->session->userdata('user_id'); ?>" ;
var formData = {user_id:user_id};
ajax_update_content_when_page_is_loaded_beers(formData);
}
function ajax_update_content_when_page_is_loaded_beers(formData)
{
$.ajax({
url : '<?php echo base_url()."index.php/bartender/bartender_serve_beers"; ?>',
async : false,
type : "POST",
cache : false,
data : formData,
dataType: "html",
success : function(data)
{
alert($.trim(data));
$('#beer_output').html($.trim(data));
$('#beer_output').trigger('create'); },
error: function (jqXHR, textStatus, errorThrown)
{
$('#server_message_error_jqXHR').html("here is the jqXHR"+jqXHR);
$('#server_message_error_textStatus').html("here is the textStatus "+textStatus);
$('#server_message_error_errorThrown').html("here is the errorThrown"+errorThrown);
}
});
}
});
once the form is submitted
$(".beer").on("submit",function(event)
{
//variables
var delete_beer = $(this).find(".delete_beer").val();
var beer_id = $(this).find(".beer_id").val();
var user_id ="<?php echo $this->session->userdata('user_id');?>";
// alert( "delete_beer="+delete_beer+"beer_name=" +beer_name +"beer_id="+beer_id );
//form variables
var formData = {delete_beer:delete_beer,beer_id:beer_id,user_id:user_id}; //Array
submit_ajax_form_beers(formData);
//get_beers_from_customer();
});
function submit_ajax_form_beers(formData)
{
$.ajax({
url : '<?php echo base_url()."index.php?/bartender/bartender_serve_beers"; ?>',
async : false,
type : "POST",
cache : false,
data : formData,
dataType: "html",
success : function(data){
$('#beer_output').trigger('create');
console.log($(this).data(formData));
},
error: function (jqXHR, textStatus, errorThrown){
$('#server_message_error_jqXHR').html("here is the jqXHR"+jqXHR);
$('#server_message_error_textStatus').html("here is the textStatus "+textStatus);
$('#server_message_error_errorThrown').html("here is the errorThrown"+errorThrown);
}
});
}
代码点火器控制器
public function process_order_when_all_drinks_served($user_id)
{
$bartender_id = $this->session->userdata('bartender_id');
//load model
$this->load->model('authorizenet_model');
//finalize order with authorizenet prior authorize and capture
$response = $this->authorizenet_model->priorauthcapture($user_id);
print_r($response);
if($response->response_code=="1")
{
//stores the order_line before it is deleted
$this->bartender_model->store_past_order_line($user_id);
//deletes customer from order line if all beers and mixed drinks have been served
$this->bartender_model->delete_customer_from_order_line($user_id);
//order was successful
$response_message= '<center><strong>'.$response->response_reason_text.'</strong></center>';
}
else
{
//store userdata in unprocess orders
$this->bartender_model->store_unprocessed_order($user_id,$bartender_id);
//then erases it from order_line
$this->bartender_model->delete_customer_from_order_line($user_id);
$response_message= '<center><strong style="color:red;">'."There was a problem with the order.<br/>"
.$response->response_reason_text.$response->error_message.'</strong></center>';
}
return $response_message;
}
public function bartender_serve_beers(){
//checks if there are any drinks left to process order
if(isset($_POST['delete_beer']) && isset($_POST['user_id'])
{
$user_id = $_POST['user_id'];
$beer_id = $_POST['beer_id'];
//then it is deleted from the paid beers
$this->bartender_model->delete_beers($user_id,$beer_id);
//checks if there are any drinks left to be processed
$checks_any_drinks_left= $this->bartender_model->checks_if_mixed_drinks_beers_left_to_process_order($user_id);
if($checks_any_drinks_left=="1")
{
$user_id = $this->session->userdata('user_id');
$proccess_drinks_message= $this->process_order_when_all_drinks_served($user_id);
//outputs the response message to bartender
echo $proccess_drinks_message;
}
else
{
$user_id = $this->session->userdata('user_id');
//continues outputting beers
echo $beers_served_button = $this->bartender_model->output_beers_served_button($user_id);
}
}
else
{
$user_id = $this->session->userdata('user_id');
echo $beers_served_button = $this->bartender_model->output_beers_served_button($user_id);
}
}
我不认为有必要将会话变量输出到前端。下一个控制器中也会有它。最好是检查下一个控制器，如果它仍然存在的话。在其他内容中添加一个签入，如：
//...
else if ($this->session->userdata('user_id') != false && !empty($this->session->userdata('user_id')) ) {
$user_id = $this->session->userdata('user_id');
//continues outputting beers
echo $beers_served_button = $this->bartender_model->output_beers_served_button($user_id);
}//...rest of the code
另外，检查$_POST['delete_beer']，然后将$_POST['beer_id']分配给$beer_id变量。虽然我看不出您通过AJAX传递了任何beer变量。据我所见，您只传递会话输出。
