mysql_insert_id() is returning 0

Question

I've looked through the various answers and none of them seem to be helping. I have a simple Insert Query that is working as expected. Nothing special

$user_account_query = mysqli_query($dbc,"
        INSERT INTO ACCOUNT (EMAIL, IS_OPEN)
        VALUES ('$email', 1)")
        or die ('Could not add user: '. mysql_error());

It is successfully inserting the record into my db

I also have an auto-incrementing column in the table being called

However, when I call

$message = mysql_insert_id();

I get 0. Does anyone have any advice on how to get the correct ID?

Answer 1

You're mixing up mysql and mysqli

$message = mysql_insert_id();

should be

$message = mysqli_insert_id($dbc);

Answer 2

实际上，您正在使用myqli Libraray，然后使用其他库函数mysql_insert_id（），则必须使用mysqli_insert_id（），这就是为什么您获得0
