"Invalid File Format" error when trying to submit form - php

Question

When I try to submit my form, it can't be submitted and shows an "invalid file format" error, no matter if any data is input or not. The file format code was collected from StackOverflow.
if(isset($_POST['submit']))
{
$type=2;
$fname = #$_POST['f_name'];
$eml = #$_POST['email_id'];
$mo_num = #$_POST['mn'];
$message = #$_POST['message'];
$uploaded_file_a= #$_FILES['file_a']['name'];
$uploaded_file_b= #$_FILES['file']['name'];
// in a Array > all Supported Document Formats are Stored //
$allowedExts = array("pdf", "doc", "docx", "ppt", "pptx","jpeg","jpg","png","x-png");
// In a Temporary Array > The File Name + File Extension is Stored //
$temp = explode(".", $_FILES["file"]["name"]);
// Getting the Extension //
$extension = end($temp);
// Checking File // PDF | DOC | DOCX | XLS | XLSX | PPT | PPTX

i have modified you code to handle if no file is submitted.
if(isset($_POST['submit']))
{
$type=2;
$fname = #$_POST['f_name'];
$eml = #$_POST['email_id'];
$mo_num = #$_POST['mn'];
$message = #$_POST['message'];
$uploaded_file_a= #$_FILES['file_a']['name'];
$uploaded_file_b= #$_FILES['file']['name'];
// in a Array > all Supported Document Formats are Stored //
$allowedExts = array("pdf", "doc", "docx", "ppt", "pptx","jpeg","jpg","png","x-png");
// In a Temporary Array > The File Name + File Extension is Stored //
$temp = explode(".", $_FILES["file"]["name"]);
// Getting the Extension //
$extension = end($temp);
// Checking File // PDF | DOC | DOCX | XLS | XLSX | PPT | PPTX
