PHP DOP Insertar usando Loop
Estoy teniendo problemas para usar PDO para insertar varios registros en una base de datos. Puedo agregar exitosamente un solo registro, pero tan pronto como agrego elforeach bucle, falla Después de leer una serie de otras preguntas de SO con respecto a esto, creo que necesito "unir" mis variables, aunque estoy completamente confundido con la sintaxis correcta.
Aquí está la función original que he creado:
<? function addToDatabase () {
//Get All Variables
$timestamp = date("Y-m-d H:i:s");
$schoolName = $_SESSION['schoolName'];
$schoolStreet = $_SESSION['schoolStreet'];
$schoolCity = $_SESSION['schoolCity'];
$schoolState = $_SESSION['schoolState'];
$schoolZip = $_SESSION['schoolZip'];
$schoolContactName = $_SESSION['schoolContactName'];
$schoolContactTitle = $_SESSION['schoolContactTitle'];
$schoolContactPhone = $_SESSION['schoolContactPhone'];
$schoolCsontactEmail = $_SESSION['schoolContactEmail'];
$inputMethod = $_SESSION['inputMethod'];
$studentDataArray = $_SESSION['studentDataArray'];
$studentFirstNameField = $_SESSION['studentFirstNameField'];
$studentLastNameField = $_SESSION['studentLastNameField'];
$studentStreetField = $_SESSION['studentStreetField'];
$studentCityField = $_SESSION['studentCityField'];
$studentStateField = $_SESSION['studentStateField'];
$studentZipcodeField = $_SESSION['studentZipcodeField'];
$studentDOBField = $_SESSION['studentDOBField'];
$studentGenderField = $_SESSION['studentGenderField'];
$studentGradeField = $_SESSION['studentGradeField'];
//Connnect to Database
$host = 'myHost';
$un = 'myUsername';
$pw = 'myPassword';
$db_name = 'myTable';
try {
$conn = new PDO("mysql:host=$host;dbname=$dbName", $un, $pw);
echo 'Connected to database<br>';
$sql = "INSERT INTO studentData (originallyAddedOn, inputMethod, studentFirst, studentLast, studentStreet, studentCity, studentState, studentZip, studentDOB, studentGender, studentGrade, schoolName, schoolStreet, schoolCity, schoolState, schoolZip, schoolContactName, schoolContactTitle, schoolContactEmail, schoolContactPhone) VALUES (:originallyAddedOn, :inputMethod, :studentFirst, :studentLast, :studentStreet, :studentCity, :studentState, :studentZip, :studentDOB, :studentGender, :studentGrade, :schoolName, :schoolStreet, :schoolCity, :schoolState, :schoolZip, :schoolContactName, :schoolContactTitle, :schoolContactEmail, :schoolContactPhone)";
foreach ($studentDataArray as $student){
$q = $conn->prepare($sql);
echo $student[$studentFirstNameField]."<br>";
$q->execute(array( ':originallyAddedOn'=>$timestamp,
':inputMethod'=>$inputMethod,
':studentFirst'=>$student[$studentFirstNameField],
':studentLast'=>$student[$studentLastNameField],
':studentStreet'=>$student[$studentStreetField],
':studentCity'=>$student[$studentCityField],
':studentState'=>$student[$studentStateField],

':schoolZip'=>$schoolZip,

':schoolContactPhone'=>$schoolContactPhone));
}
// close the database connection
$dbh = null;
}
catch(PDOException $e) {
echo $e->getMessage();
}
}
los$studentDataArray se parece a esto:
0 => //student 1
array
[0] => 'Joe' //First
[1] => 'Smith' //Last
[2] => '101 Main St' //Street
[3] => 'Boston' //City
[4] => 'MA' //State
[5] => '01234' //Zip
[6] => '2000-01-01' //Date of Birth
[7] => 'Male' //Gender
[8] => '12' //Grade
1 => //Student 2
array
[0] => 'Jane'
[1] => 'Smith'
[2] => '99 Main St'
[3] => 'Boston'
[4] => 'MA'
[5] => '01234'
[6] => '2000-02-02'
[7] => 'Female'
[8] => '10'
