Error using Cake PHP SQL Server Driver - php

Question

Upgraded a (dev) Cake PHP site and had to change database drivers from ADO to SQL Server's own driver as ADO is no longer supported in Cake 1.3, I . The new SQL Server driver is installed in PHP, shows in PHPinfo() and should work, but when I try to load a page using the database, I get this error:
Warning (2): sqlsrv_query() expects parameter 1 to be resource, boolean given
[APP\plugins\datasources\models\datasources\dbo\dbo_sqlsrv.php, line 184]
Warning (512): SQL Error: An invalid parameter was passed to sqlsrv_query.
[CORE\cake\libs\model\datasources\dbo_source.php, line 684]
Query: SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES
What appears to be happening is my connection isn't established in the dbo_sqlsrv.php driver; a "$this->connection" variable is supposed to be the connection resource then passed to sqlsrv_query() and it's apparently a bool which is wrong (I tried to Echo the variable and it displays nothing).
This is where the connection SHOULD be set:
sqlsrv_connect($this->config['host'] . $port, $params)
Printing the variables that were passed in gives me this:
SRV, 1433 Array ( [Database] => DB [CharacterSet] => char
[MultipleActiveResultSets] => [UID] => sa [PWD] => password )
Each of those parameters is correct, is there a specific way I should format or change my database configuration array for this driver or is there something I am missing?

Answer 1

This error was due to outdated SQL Server drivers. Installing the latest from below allows a SQL Server connection:

Answer 2

I think there is some issue with your connection. PHP can't establish connection with sql Server.
var $default = array(
'driver' => 'sqlsrv',
'persistent' => false,
'host' => 'Myhome-PC\SQLEXPRESS', // or ip-address(192.168.1.13)
'login' => 'username',
'password' => 'password',
'database' => 'db',
'prefix' => 'tbl',
'port' => NULL,
'returnDatesAsStrings' => True
);
I think the Connection should be this
Here is the sqlsrv_dbo which I used.
And your $param should be something like this
$connectionInfo = array("UID" => $config['login'],
"PWD" => $config['password'],
"Database" => $config['database'],
'MultipleActiveResultSets' => 1,
'ConnectionPooling' => 0
);
if(isset($config['ReturnDatesAsStrings'])){
$connectionInfo['ReturnDatesAsStrings'] = $config['ReturnDatesAsStrings'];
}
$this->connection = sqlsrv_connect($config['host'] . $port, $connectionInfo);
