isset($_POST[] ) not working

Question

i got this file upload.html where below code resides, and everytime i browse file and submit its failing at isset($_POST). it echoes "didn't upload", its working fine with same file in another folder. all i did was move the whole website folder content to another folder, and it stopped working.

   <h3>File Upload:</h3>
Select a file to upload: <br />
<form method="post" action="" enctype="multipart/form-data">
<input type="file" name="file" size="50" />
<br />
<input type="submit" name="uploadxls" value="Upload File" />
</form>



<?php

include("../include/processxls.php");

date_default_timezone_set('America/Chicago');

if (isset($_POST['uploadxls']) && !empty($_POST['uploadxls']))
{
    echo "test point";
    uploadReport();
}
else 
{
    echo "didn't upload";
}



function uploadReport()
{

$report=basename($_FILES['file']['name']);
$report=str_replace(' ','|',$report);

$tmppath="uploads/".$report;

    if(move_uploaded_file($_FILES['file']['tmp_name'],$tmppath))
    {
        echo " File upload success. Please wait while report is processed....... "; 

        processxls($tmppath);
    }
    else
    {
        echo "fail";
    }   
}

?>

Have you tried this in different browsers? Which browser are you using? — PavKR, Jun 26 '15 at 00:30
Try `print_r($_REQUEST)` and see if that gives you anything. Post your results here so we can see. — PavKR, Jun 26 '15 at 00:45

Do you have any other scripts running that could redirect a $_POST request? eg. something like a rewrite script? (any includes at the top maybe?) — PavKR, Jun 26 '15 at 00:58
using admin panel bootstrap, and using angularjs controller to load this upload page. — Vishal Desai, Jun 26 '15 at 01:02
but if i try even without admin panel stuff and just do plain upload.html file and php that I'm including it still fails to POST — Vishal Desai, Jun 26 '15 at 01:09
Try this: `print_r(file_get_contents("php://input"));` and see what you get. — PavKR, Jun 26 '15 at 01:11

Stupid question: Did you also move the `../include/processxls.php` such that its location is still appropriately relative to this php file? — kittykittybangbang, Jun 26 '15 at 01:30
yes i did, and I'm not getting php related errors, POST is just simply not happening for some reason, i made a copy of original version that is functioning to godaddy server, it didn't work and then i changed the upload.html to upload.php it started working. — Vishal Desai, Jun 26 '15 at 02:48

Different browsers ignore the value of submit buttons and do not send this data with the POST

Use a hidden input field instead, and then this will be submitted regardless of browser.

<input type='hidden' name="uploadxls" value="Upload File">

You still need a submit button to submit your form. skrilled means to move the "uploadxls" to another field because not all browser submit the value of a submit button. – hildende Jun 26 '15 at 00:34
still same thing, the same web site content is in another folder and when i visit that url in same browser it works fine. – Vishal Desai Jun 26 '15 at 00:39
i even did just if ($_POST) that doesn't work either – Vishal Desai Jun 26 '15 at 00:41

You should determine if it is a post using $_SERVER['REQUEST_METHOD']

if( $_SERVER['REQUEST_METHOD'] === "POST" ) {
    // Do checks and logic
}

That way you don't need to worry about the browser sending the submit button or using hidden values. PHP has a built in variable for it, may as well use it.
