PHP / MYSQL事务生成两个相同的主键
我有一个用作Web服务的函数。代码如下所示。
public function create_order() {
try{
$this->db->trans_begin();
$this->form_validation->set_rules($this->form_validation_array->get_app_rules('authenticate'));
$this->form_validation->set_rules("table_id","Table_id","required");
// $this->form_validation->set_rules("item[]","Items","required");
if ($this->form_validation->run() == true) {
$credential = array(
"restaurant_id" => $this->input->post("restaurant_id"),
"app_user_id" => $this->input->post("app_user_id"),
"app_id" => $this->input->post("app_id"),
"app_secret_id" => $this->input->post("app_secret")
);
$check = $this->authenticate_app_user($credential);
if($check){
$order_data = array(

'status'=>1,
);
$order_id = $this->ws_details_model->current_order_id($order_data);
log_message('error','order_id_while_inserting '.print_r($order_id,true));
if(!$order_id) {
$order_data['unique_order_id'] = $this->common_function->unique_no('order');
$this->common_details_model->complete_existing_order($order_data);

$item_data = $this->input->post("item");
log_message('error','===============order id : '.$order.' is started====================\n');

$j=0;

log_message('error',cook_log_message('app_create_order_error',$e->getMessage()));
}
}
现在问题就出现了。
- 当此函数调用时，它会自动插入一些不在
order_item_data数组中的行。我知道它有点奇怪，但如果你可以查看下面的截图，你会明白我在说什么。
为了追溯这个问题，我已经将日志系统与我的功能放在一起了。当我检查日志时，我发现相同的主键已生成两次。 下面是日志
ERROR - 2016-11-12 21:49:07 --> ===============order id : 5091 is started====================\n
ERROR - 2016-11-12 21:49:07 --> 2016-11-12 21:49:07 : : Order array without process : order_array_without_process : Array

(

[item_quantity] => 1

)
)

[item_quantity] => 1
)
)

在上面的日志中你可以看到 order_id 5091 这是主要的关键，它生成了两次，而如果可以检查错误 - 日志时间比两者都有不同的时间比怎么可能？
以下是表格结构。
1。订购表

所以，如果有人能够理解这个问题，请帮助解决这个问题。我应该在代码中做些什么更改，这样我的数组就不会有额外的项目，而且它的主要内容与发布的数组值相同。
提前致谢。
