Merge PDF in codeigniter

Not able to locate requested PDF

Here is my function:-

function genpdf()
{
    $this->load->library('session');
    $this->load->library('PDFMerger');
    $a=$_POST['a'];
    $b=$_POST['b'];
    $pdf = new PDFMerger;
    $pdf->addPDF("samplepdfs/$a")
    ->addPDF("samplepdfs/$b")
    ->merge('file', 'http://localhost/student/samplepdfs/genpdf.pdf');
}

I need to merge different PDF into one. I am using fpdf & fpdi. I want it to be done with codeigniter. Another solutions(different methods than mentioned above) are also welcome.

Its better to check if pdf file exists before trying to add it, as you are fetching the pdf filename from POST data, like:

...
$a=$_POST['a'];
$b=$_POST['b'];

$error = false;
$errorMsg = "";
$pdf = new PDFMerger;
if( file_exists("samplepdfs/$a") ) {
    $pdf->addPDF("samplepdfs/$a");
}
else {
    $error = true;
    $errorMsg .="File:".$a." not found <br />";
}
if( file_exists("samplepdfs/$b") ) {
    $pdf->addPDF("samplepdfs/$b")
}
else {
    $error = true;
    $errorMsg .="File:".$b." not found";
}

//merge pdf if no error
if( !$error ) {
    $pdf->merge('file', 'http://localhost/student/samplepdfs/genpdf.pdf');
}
else {
    echo $errorMsg;
}
