Bug description: mysql_insert_id - Never use the function "Blank"
I copied a few lines of code from the net and got it to work in my own test
environment. When I placed the software on the production server (linux
PHP 4.1.2) - it only "almost" worked.
The problem was that it had lines with statements like:
mysql_insert_id();
where strange id's sometimes were returned !
Then, when I changed the code to:
mysql_insert_id($con); // The resource link_identifier
everything was fine. I believe that what happened was that my program
received id's from somebody else doing INSERT on the same server?
My conclusion was:
Never use the function without the
"resource link_identifier" !
And then again, - Why should you?
In the documentation it says:"If link_identifier isn't specified, the last
opened link is assumed."
My code was simply:
$sql= "INSERT INTO xrefs (referrer) VALUES ('$ref')";
echo "sql $sql <br>";
$result = mysql_query($sql,$con);
//$referrer_id = mysql_insert_id(); // FAILED
$referrer_id = mysql_insert_id($con); // WORKED OK
