用pdo在两个mysql表中插入一条记录

Question

I've been trying to do this with TWO different queries, but only the first one works. PDO is new for me that's why i'm a little confuse.

    <?php
include 'database.php';
$nombres=$_POST['tnombres'];
$apellidos=$_POST['tapellidos'];
$carrera=$_POST['tcarrera'];
$con->beginTransaction();

try{

        // insert query
        $query = "INSERT INTO alumno (nombres,apellidos) VALUES (:nombres,:apellidos)"`;`

        // prepare query for execution
        $stmt = $con->prepare($query);

        // bind the parameters
        $stmt->bindValue(':nombres',$nombres,PDO::PARAM_STR);
        $stmt->bindValue(':apellidos',$apellidos,PDO::PARAM_STR );
        $stmt->execute();
        $ultimo=$con->lastInsertId();

        $query = "INSERT INTO ficha (fechaingreso,carrera,alumno_id) VALUES (:fechaingreso,:carrera,:alumno_id)";
        $stmt = $con->prepare($query);

        $fecha=  date('d-m-Y');
        $stmt->bindValue(':fechaingreso',$fecha);
        $stmt->bindValue(':carrera',$carrera);
        $stmt->bindValue(':alumnoid',$ultimo);
        $stmt->execute();

        $con->commit(); 
        echo 'Datos insertados';
        echo '<p><a href=index.php>Inicio</a></p>';
        echo "<p>Numero de ultimo registro insertado: ",$ultimo;
    }

    // show error
    catch(PDOException $e){
        $con->rollback();
        echo $e->getMessage();
    }

Like i said before the first query works perfectly even the capture of the id from the last record inserted works but the second query don't do what it have to. I have this message of error

Warning: PDOStatement::execute(): SQLSTATE[HY093]: Invalid parameter number: parameter was not defined in C:\wamp\www\escuela\crear.php on line 32

You have a typo in your script. In your INSERT you are using alumno_id but later you try to bind the value via alumnoid .

$query = "INSERT INTO ficha (fechaingreso,carrera,alumno_id) VALUES (:fechaingreso,:carrera,:alumno_id)";

The underscore is missing - alumnoid is not the same as alumno_id .

$stmt->bindValue(':alumnoid',$ultimo);

As @FirstOne allready mentioned it: The solution is to add or remove the _ underscore from one of the both variables.
