Inserir do PHP PDO usando o Loop
Estou tendo problemas para usar o PDO para inserir vários registros em um banco de dados. Eu posso adicionar com sucesso um único registro, mas assim que eu adicionar oforeach loop, ele falha. Depois de ler uma série de outras perguntas sobre isso, acredito que preciso "ligar" minhas variáveis, embora esteja completamente confuso sobre a sintaxe apropriada.
Aqui está a função original que criei:
<? 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],

':schoolContactPhone'=>$schoolContactPhone));
}
// close the database connection
$dbh = null;
}
catch(PDOException $e) {
echo $e->getMessage();
}
}
o$studentDataArray é semelhante a isso:
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'
