Codeigniter insert data results in PHP warning

Question

I have a problem with my Codeigniter appclication at work. I'm using a virtual Windows Server 2008 R2, IIS, MSSQL and PHP

When I try to insert new records in the database, I get the following warning (for each insert):

A PHP Error was encountered

Severity: Warning

Message: array_shift() expects parameter 1 to be array, null given

Filename: sqlsrv/sqlsrv_driver.php

Line Number: 423

The code I'm using:

$data = array(
                'DataTypeSpecification'         => $dataTypeSpecID,
                'DocumentCode'                  => $docCode,
                'Title'                         => $title,
                'ProjectCode'                   => $projectCode, 
                'Process'                       => $process, 
                'Author'                        => $author,
                'Status'                        => $status,
                'Version'                       => $version, 
                'DateApproval'                  => $dateApproval,
                'Medium'                        => $medium, 
                'PaperArchivedDate'             => $paperArchivedDate, 
                'DMSArchivedDate'               => $DMSArchivedDate,
                'EDocDocument'                  => $eDocDocument,
                'Wildcard'                      => $wildcard, 
                'SequentialNumber'              => $seqNumber, 
                'Location'                      => $location, 
                'ArchivedShelf'                 => $archivedShelf,
                'Container'                     => $container, 
                'Remarks'                       => $remakrs, 
                'APDProjectStatus'              => $APDProjectStatus, 
                'SelectedForIND'                => $selectedForIND);

$result = $this->db->insert('dbo.ProjectRecords', $data);
return $result;

All of the variables are set correctly. Here is the funny thing. It seems that everything gets inserted correctly in the database...

Anyone knows why this warning is displayed?

Answer 1

So, I had to edit the driver itself. I changed the file system/database/sqlsrv/sqlsrv_driver.php The two functions _error_message() (line 407) and _error_number() (line 423)

In both of them, i changed the first two lines to:

$tmp = sqlsrv_errors();
if($tmp == null) return null;
$error = array_shift($tmp);

So that i.e. _error_number() becomes:

function _error_number()
{
    $tmp = sqlsrv_errors();
    if($tmp == null) return null;
    $error = array_shift($tmp);
    return isset($error['SQLSTATE']) ? $error['SQLSTATE'] : null;
}

The error occurs since sqlsrv_errors() returns NULL, and when passing NULL to the array_shift() method, baaad things happens!
