"Notice (8): Undefined index: " cakephp

I am building a pdf conversion utility for my user. I am working in CakePhp and my controller is receiving Ajax call. Why i am getting Notice:8 error

Controller:

public function convertToPdf() {
            $this->autoRender = false;
            $pdf = new WkHtmlToPdf;
            //$this->RequestHandler->respondAs('json');
            // echo $convertData = json_encode($inputVal);

            if ($this->RequestHandler->isAjax()) {
                $pdfName = uniqid();
                if ($_FILES['conversionSourceFile']) {
                    echo "File";
                    $pdf->addPage($_FILES['conversionSourceFile']['tmp_name']);
                } elseif ($_POST['conversionSourceUrl']) {
                    echo "Url";
                    $pdf->addPage($_POST['conversionSourceUrl']);
                } elseif ($_POST['conversionSourceHtml']) {
                    echo "Html";
                    $pdf->addPage('<html>' . $_POST['conversionSourceHtml'] . '</html>');
                }

                $saveToPath = 'upload/' . $pdfName . '.pdf';
                if ($pdf->saveAs($saveToPath)) {
                    echo 'upload/' . $pdfName . '.pdf';
                }
            }
        }

I solved the error "Notice (8): Undefined index" changing the order var $ uses.

before:

class GastosController extends AppController {  
    var $uses = array('Comprobante','Gasto','TipoGasto');

... ... ..

After:

class GastosController extends AppController {  
    var $uses = array('Gasto','Comprobante','TipoGasto');

.. .. ..

Put the name that corresponds to the class (Gasto) first.

To avoid notice in your code you have to use isset() OR !empty().

Using isset() and !empty() you can check whether variable is set and does not have an empty value.

e.g,

if (isset($_FILES['conversionSourceFile'])) {
    // your code
}

OR

if (!empty($_FILES['conversionSourceFile'])) {
    // your code
}

You need to check the first condition, with an "isset" or "!empty ()", like:

if(isset($_FILES['conversionSourceFile'])){...}

Simply check to isset $_FILES superglobal variable to prevent notice when not set.

if (isset($_FILES['conversionSourceFile'])) {
    // Do more stuff
}
