PHP insert into mysql database with dates - php

Question

I would like to be able to add children into a database, which are connected to their parents (who has a member id MID). I believe that the error lies within the date format (atleast that's what I believe), I have also tried to use strtotime($dob), however this didn't change anything.
$name = htmlspecialchars($_GET['Name']);
$dob = $_GET['DOB'];
$newDOB = date("Y-m-d", $dob);
$mid = $_GET['mid'];
if(isset($_GET['Name'], $_GET['DOB'], $_GET['mid']))
$alert = true;
if(!empty($name) && !empty($newDOB) && !empty($mid))
add_family_member($mid, $newDOB, $name);
The function that adds the member:
function add_family_member($mid, $dob, $name)
{
global $con;
$sql = "INSERT INTO Children(MID, DOB, Name) VALUES(?, ?, ?)";
$stmt = $con->prepare($sql);
if($stmt)
{
$b = $stmt->bind_param("iss", $mid, $dob, $name);
if($b)
{
$e = $stmt->execute();
if($e)
return true;
}
}
return false;
}

Answer 1

function add_family_member($mid, $dob, $name)
{
global $con;
$sql = "INSERT INTO Children(MID, DOB, Name) VALUES(:mid, :dob, :name)";
$stmt = $con->prepare($sql);
if($stmt)
{
return $stmt->execute(array(
'mid' => $mid,
'dob' => $dob,
'name' => $name
));
}
return false;
}

Try...
function add_family_member($mid, $dob, $name)
{
global $con;
$sql = "INSERT INTO Children(MID, DOB, Name) VALUES(:mid, :dob, :name)";
$stmt = $con->prepare($sql);
$stmt->bindParam(':mid', $mid);
$stmt->bindParam(':dob', $dob);
$stmt->bindParam(':name', $name);
if ($stmt->execute()) {
return true;
}
return false;
}
