我想通过输入名称在RESTAURANT表中创建一家餐厅。RestaurantID(RID) 是自动递增的。但同时,我想在RATING表中创建一个包含最新添加的 RID 的行。
其他帖子中的几个问题与我的情况不同,我不知道如何解决这个问题。不得不从这里寻求帮助..
这段代码的测试结果是:{"success":0,"message":"Fail to create Rating table for this restaurant!"}
餐厅名称已成功添加,但评分表不起作用。有什么想法吗?还是我应该反过来将 RID 添加到评级表中?
这是我的代码:
$response = array();
$name = "test1";
if ($rid = addRestaurant($name)){
echo "$rid"; // now it displays the right id
if(addRating($rid) == true){
$response["success"] = 1;
$response["message"] = "Restaurant Successfully Created!";
echo json_encode($response);
}else{
$response["success"] = 0;
$response["message"] = "Fail to create Rating table for this restaurant!";
echo json_encode($response);
}
}else{
$response["success"] = 0;
$response["message"] = "Fail to create Restaurant! Please Try Again Later!";
echo json_encode($response);
}
function addRestaurant($name){
// mysql inserting a new row
$result = mysql_query("INSERT INTO restaurants (Name)VALUES('$name')");
// check if row inserted or not
if ($result) {
$rid = mysql_insert_id();
echo "$rid"; //this gives me correct RID of "84" latest one.
return $rid;
} else {
return false;
}
}
function addRating($rid){
echo "$rid"; // here also the latest ID. but why return false?
$result = mysql_query("INSERT INTO `rating`(`Clealiness`, `Service`, `Quality`, `RID`) VALUES ('0', '0', '0', $rid");
if ($result) {
return true;
} else {
return false;
}
?>
