Fatal error call to a member function get on a non object in

Apparently

$ballpark = $this->ballparkDetailsHandler->getBallparkDetailsByProjectId($projectId);

is not returning a «ballpark» at all. Probably it is returning an error, or something like an empty array.

Try var_dump()‘ing $ballpark immediately before the line that raises the error, and see what it contains (probably False, NULL, array() or something equally un-ballparky.

Then, inspect the ballparkDetailsByProjectId() function in the BallparkDetailsHandler.php file. At a guess, you might be passing an invalid (i.e. nonexistent, removed, etc.) $projectId.

Then you might rewrite the code with error checking:

if($projectStatusId == ProjectStatusKeys::BALLPARK_ACTIVE) {
        $ballpark = $this->ballparkDetailsHandler->getBallparkDetailsByProjectId($projectId);
        if (!is_object($ballpark))
            trigger_error("Error: bad project ID: '$projectId': $ballpark",
                E_USER_ERROR);

        $projectDetails["startdate"] = $ballpark->getBallparkDetailsStartDate();
        $projectDetails["enddate"] = $ballpark->getBallparkDetailsEndDate();
        $projectDetails["projectid"] = $projectId;
        $projectDetails["name"] = $ballpark->getBallparkDetailsBookingRef();
        $projectDetails["status"] = ProjectStatusKeys::BALLPARK_ACTIVE; 
    }

Then in the BallparkDetailsHandler.php file you could modify this code:

// Prepare query or die
if (!($stmt = $this->mysqli->prepare($query))
    return "Error in PREPARE: $query";

$stmt->bind_param("i", $projectId);
$stmt->execute();
$stmt->store_result();
$stmt->bind_result($ballparkDetailsBookingRef, $bankRef, $regionName,
     $projectStatusId, $projectStatusName,  $ballparkDetailsDescription,
     $ballparkDetailsNotes, $ballparkDetailsStartDate, $ballparkDetailsEndDate,
     $ballparkDetailsExpiryDate);
$stmt->fetch();

// If no data, then die
if(!$stmt->num_rows)
    return "No data in DB for projectID '$projectId': $query";

// Should be clear sailing from here on. Actually I ought to check
// whether all these new() here do return anything sensible, or not

$bank = new Bank("", "", $bankRef, "");
$region = new Region("", $regionName, "");
$projectStatus = new ProjectStatus($projectStatusId, $projectStatusName);
$project = new Project($projectId, $bank, $region, $projectStatus);

return new BallparkDetails("", $project,
    $ballparkDetailsBookingRef, $ballparkDetailsStartDate, 
    $ballparkDetailsEndDate, $ballparkDetailsExpiryDate, 
    $ballparkDetailsDescription, $ballparkDetailsNotes);

Trying to move from local host to new server. Fresh install worked fine, no problems. When I uploaded my files mydomain.com/admin comes up with a white screen and mydomain.com produces this error:

Fatal error: Call to a member function get() on a non-object in /home4/pawpostc/public_html/index.php on line 103.

So I took a look at index.php line 103:

if ($config->get('config_error_display')) {
        echo '<b>' . $error . '</b>: ' . $errstr . ' in <b>' . $errfile . '</b> on     line <b>' . $errline . '</b>';
    }

Seems like there is a problem with my config files. So I went and had a look at them. I have gone over them a few times but can not find the mistake, probably missing something, so here are the config files.

config.php (in my root www. folder):

Any help on this would be appreciated.

I am trying to duplicate a view and modify it, but it is giving me an error.

Before this, I did it with other views and it worked perfectly, all I had to do was rename the views and modify the code.

But now , I get this error:

Fatal error: Call to a member function get() on a non-object in D:UniServerZvhostsrestaurantadministratorcomponentscom_restaurantviewsreviewsview.html.php on line 54

Line 54 has this code:

$canDo = RestaurantHelper::getActions($state->get('filter.category_id'));

var_dump($this); gives me the following ->
