Closed 9 years ago.
I want to get all the list of registered players from an array
here is my function
function UpdateContact()
{
try {
$conn = $this->GetDBConnection();
$linkedInId = trim($_REQUEST['linkedInId']);
$statement = $conn->prepare('UPDATE users SET linkedInId = :linkedInId WHERE linkedInId = :linkedInId');
$statement->bindParam(':linkedInId', $linkedInId, PDO::PARAM_STR);
$statement->execute();
//$updatedTime = time() - 120;
$ids = implode(",",$_POST['ids']);
// $ids = (abc,def,geh,ijk,lac);
$statement = $conn->prepare('SELECT * FROM users WHERE linkedInId IN (:ids)');
$statement->execute($ids);
$conn = null;
if (!($row = $statement->fetchAll(PDO::FETCH_ASSOC)))
return false;
else
return $row;
} catch(PDOException $e) {
throw $e;
}
}
Just return false
Maybe because i am not able to bind the array with PDO Statement?
How can I fix this solution, i might want to add more binding parameters too later on, so i don't want to do execute($ids) either.
I have tried bindParam(':ids',$ids) too but of no avail
$items = array();
//$statement->bindParam(':updatedTime', $updatedTime, PDO::PARAM_STR);
foreach ($id as $ids)
{
$statement = $conn->prepare('SELECT * FROM users WHERE id = :id');
$statement->bindParam(':id', $id, PDO::PARAM_STR);
$statement->execute();
if(($row = $statement->fetch(PDO::FETCH_OBJ)))
$items[] = $id;
}

I think it would make more sense to parse the array/list and perform the select for each id in the array/list.
Pseudo code:
init resultArray;
For x in List
select * from database where ids =: x
if result
add result to resultArray
return resultArray
But that's just the basic way of doing it, I'm not sure if you can do it more advanced.
