PDO: date not inserting, suggestions? - php

Question

I'm trying to insert a date into the database using the following code, I get the following error: Error: SQLSTATE[22007]: Invalid datetime format: 7 ERROR: invalid input syntax for type date: ""
So the date is not being passed, yet I can return the date from the POST: echo $_SESSION['dateOpen']; this returns the date as 2014-06-01
I'm a bit of a noob, so any suggestions are welcome. Using postgresql database.
try {
$sql2 = "INSERT INTO excavation.contexts_spatial
(area_easting,
area_northing,
context_number,
open_date,
close_date,
excavation_method,
contamination,
zooarchaeology_comments,
ceramic_comments) VALUES (
:area_easting,
:area_northing,
:context_number,
:open_date,
:close_date,
:excavation_method,
:contamination,
:zooarchaeology_comments,
:ceramic_comments)";
$stmt2 = $conn->prepare($sql2);
// prepare sql and bind parameters
$stmt2->bindParam(':area_easting', $area_easting, PDO::PARAM_INT);
$stmt2->bindParam(':area_northing', $area_northing, PDO::PARAM_INT);
$stmt2->bindParam(':context_number', $nextContext, PDO::PARAM_INT);
$stmt2->bindParam(':open_date', $open_date, PDO::PARAM_STR);
$stmt2->bindParam(':close_date', $close_date, PDO::PARAM_STR);
$stmt2->bindParam(':excavation_method', $excavation_method, PDO::PARAM_STR);
$stmt2->bindParam(':contamination', $contamination, PDO::PARAM_STR);
$stmt2->bindParam(':zooarchaeology_comments', $excavation_method, PDO::PARAM_STR);
$stmt2->bindParam(':ceramic_comments', $excavation_method, PDO::PARAM_STR);
// insert a row
$area_easting = $_SESSION['area_easting'];
$area_northing = $_SESSION['area_northing'];
$nextContext = $_SESSION['nextContext'];
$open_date = $_SESSION['dateOpen'];
$close_date = $_SESSION['dateClose'];
$excavation_method = $_SESSION['excavationMethod'];
$contamination = $_SESSION['contamination'];
$zooarchaeology_comments = $_SESSION['zooarchaeologyComments'];
$ceramic_comments = $_SESSION['ceramicComments'];
$stmt2->execute();
echo "New records created successfully in contexts spatial<br />";
}
catch(PDOException $e)
{
echo "Error: " . $e->getMessage();
}

Answer 1

You are executing the query twice: Once before you assign your session variables to the parameters you have bound in the query and once after.
You need to remove the first $stmt2->execute(); statement.
