Explanation / Answer

This is upload.php file that you need for your program:


<?php

$allowedExts = array("txt", "pdf", "dxf", "png");

$temp = explode(".", $_FILES["file"]["name"]);

$extension = end($temp);

if ((($_FILES["file"]["type"] == ".tmpFiles/txt")

|| ($_FILES["file"]["type"] == ".tmpFiles/pdf")

|| ($_FILES["file"]["type"] == ".tmpFiles/dxf")

|| ($_FILES["file"]["type"] == ".tmpFiles/png")

&& ($_FILES["file"]["size"] < 300000)

&& in_array($extension, $allowedExts))

{

if ($_FILES["file"]["error"] > 0)

{

echo "Error: " . $_FILES["file"]["error"] . "<br>";

}

else

{

echo "Upload: " . $_FILES["file"]["name"] . "<br>";

echo "Type: " . $_FILES["file"]["type"] . "<br>";

echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";

echo "Stored in: " . $_FILES["file"]["tmp_name"];

}

}

else

{

echo "Invalid file";

}

?>
