Question

I’ve created a function in php to add some information to a table. However the ID gets created upon entry. But I need that Id in order to perform another task, but I’m not actually sure how to get that entry.

SO my function is this:

addSkillset($agent, $computing, $tactical, $driving);

Which does this:

function addProperty($agent, $computing, $tactical, $driving) {
    $mysqli = new mysqli(DB_SERVER, DB_USER, DB_PASSWORD, DB_NAME);
    if (!$mysqli) {
            die('There was a problem connecting to the database.');
    }
    else {
    $query = "INSERT INTO Skillset VALUES (NULL, '$agent', '$computing', '$tactical', '$driving')";
    }
    if ($Results = mysql_query($query)){
    echo "added";
    }
    $mysqli->close();
}

So in this query, the ‘NULL’ bit is what I’m trying to identify and return.

I assume I would have to put:

if ($Results = mysql_query($query)){
    $somesortofvariable = somesortofcommand;
    return $somesortofvariable;
}

But I’m not totally sure.

You are looking for mysqli_insert_id()

if ($Results = mysqli_query($query)){
    $somesortofvariable = mysqli_insert_id();
    return $somesortofvariable;
}
