Can't upload larage size pdf file in laravel [duplicate] - php

Question

I am getting the undefined index error as I come for the first time in my upload form page or if I move to next page and click on back button then I have the same error message.
If I upload a file then it works fine and the error message gets away.
I have also tried this:
global $file;
if (!isset($file)) {
$file = '';
}
Here is my code:
<form id="uploadForm" name="upload" enctype="multipart/form-data"/>
<fieldset>
<input type="hidden" name="MAX_FILE_SIZE" value="30000" />
<input type="file" name="file" />
<?php
echo '<pre>';
var_dump($_REQUEST['file']);
echo '</pre>';
$uploaded = new upload;
//set Max Size
$uploaded->set_max_size(350000);
//Set Directory
$uploaded->set_directory("data");
//Set Temp Name for upload.
$uploaded->set_tmp_name($_FILES['file']['tmp_name']);
//Set file size
$uploaded->set_file_size($_FILES['file']['size']);
//set file type
$uploaded->set_file_type($_FILES['file']['type']);
//set file name
$uploaded->set_file_name($_FILES['file']['name']);
//start copy process
$uploaded->start_copy();
if($uploaded->is_ok())
echo " upload is doen.";
else
$uploaded->error()."<br>";
?>

var $user_full_name;
function set_directory($dir_name =".")
{
$this->directory_name = $dir_name;
}
function set_max_size($max_file = 2000000)
{
$this->max_filesize = $max_file;
}
function error()
{
return $this->error;
}
function is_ok()
{
if(isset($this->error))
return FALSE;
else
return TRUE;
}
function set_tmp_name($temp_name)
{
$this->user_tmp_name = $temp_name;
}
function set_file_size($file_size)
{
$this->user_file_size = $file_size;
}
function set_file_type($file_type)
{
$this->user_file_type = $file_type;
}
function set_file_name($file)
{

if (!empty($this->directory_name))

"Undefined index" means you're trying to read an array element that doesn't exist.
Your specific problem seems to be that you're trying to read upload data that doesn't exist yet: When you first visit your upload form, there is no $_FILES array (or rather, there's nothing in it), because the form hasn't been submitted. But since you don't check if the form was submitted, these lines net you an error:
//Set Temp Name for upload.
$uploaded->set_tmp_name($_FILES['file']['tmp_name']);
//Set file size
$uploaded->set_file_size($_FILES['file']['size']);
//set file type
$uploaded->set_file_type($_FILES['file']['type']);
//set file name
$uploaded->set_file_name($_FILES['file']['name']);
They're all trying to read the value of $_FILES['file'] to pass them to the methods of $uploaded.
What you need is a check beforehand:
if (isset($_FILES['file'])) {
$uploaded = new upload;
//set Max Size
$uploaded->set_max_size(350000);
//Set Directory
$uploaded->set_directory("data");
//Set Temp Name for upload.
$uploaded->set_tmp_name($_FILES['file']['tmp_name']);
//Set file size
$uploaded->set_file_size($_FILES['file']['size']);
//set file type
$uploaded->set_file_type($_FILES['file']['type']);
//set file name
$uploaded->set_file_name($_FILES['file']['name']);
//start copy process
$uploaded->start_copy();
if($uploaded->is_ok())
echo " upload is doen.";
else
$uploaded->error()."<br>";
}

The error is probably in your upload class. The error message is pretty clear, if that is the actual message you get there is probably a line somewhere in that class that looks for an array key I that is named 'fileUpload'.
Just do a search in your code for 'fileUpload', and add something to check if the key is set, ie
if(isset($arraywhatever['fileUpload'])) condition to your code.
