Is there a way I can put these bindParam statements into one statement?

$q = $dbc -> prepare("INSERT INTO accounts (username, email, password) VALUES (:username, :email, :password)");
$q -> bindParam(':username', $_POST['username']);
$q -> bindParam(':email', $_POST['email']);
$q -> bindParam(':password', $_POST['password']);
$q -> execute();

I was using mysqli prepared before where it was possible, I switched to PDO for assoc_array support. On the website for PDO it shows them on seperate lines, and in all examples I have seen it is on seperate lines.

Is it possible?



Example 2 on the execute page is what you want:

$sth->execute(array(':calories' => $calories, ':colour' => $colour));

You may want to look at the other examples too. With question mark parameters, it would be:

$q = $dbc -> prepare("INSERT INTO accounts (username, email, password) VALUES (?, ?, ?)");
$q->execute(array($_POST['username'], $_POST['email'], $_POST['password']));

If those are the only columns, you can just write:

$q = $dbc -> prepare("INSERT INTO accounts VALUES (?, ?, ?)");
$q->execute(array($_POST['username'], $_POST['email'], $_POST['password']));

The following works for me:


$pdo = new PDO("mysql:host=localhost;dbname=test", "root", "pass");
$pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);

$stmt = $pdo->prepare("INSERT INTO `null_test` (`can_be_null`) VALUES (:null)");
$stmt->bindValue(":null", null, PDO::PARAM_NULL);


Pass in PHP's null, with type of PDO::PARAM_NULL. Also, make sure your prepare emulation is set to false. That might help.

lastInsertId() is a method of the PDO class, not the PDOStatement class.

This should work:

$groupID = $dbo->lastInsertId();

Using bindParam() the variable is bound as a reference.

A string can't be passed by reference.

The following things can be passed by reference:

Variables, i.e. foo($a)

New statements, i.e. foo(new foobar())

References returned from functions

Try using bindValue()

$STH->bindValue(':id', '1', PDO::PARAM_STR);

Make sure that the type of $limit and $offset is set to PDO::PARAM_INT:

$limit = 20;
$offset = 0;

$stmt->bindParam(1, $limit,  PDO::PARAM_INT);
$stmt->bindParam(2, $offset, PDO::PARAM_INT);
