I am submitting post data from a HTML form (using javascript to validate the form) to a php script

Several hours ago I realized I was sending empty data so I fixed this problem and now I am still not receiving the post data in the server side even though I am sending it.

When I echo the post variables on the server side I can see the variables echoed when I remove the echo it keeps telling me "No login information". I tried to comment/uncomment the echo several times and it keeps showing the same problem. It seems some kind of cache.

I tried to disable cache using clearstatcache(); and

header("Content-Type: text/html");



header("Expires: 0");



header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");



header("Cache-Control: no-store, no-cache, must-revalidate");



header("Cache-Control: post-check=0, pre-check=0", false);



header("Pragma: no-cache");   

It does not work. Maybe it is some kind of cache from the html form side, apparently it keeps sending the wrong (empty) data.

When I remove the "no login information" part, it tells me "user does not exist" as when the login info is really missing.

I need to add that this code has been working well for years. I did not change it , besides the first lines for preventing to cache (but this was after the problem appeared). The new code was the html form which is calling this php code.
Part of php code follows

<?php

clearstatcache();

header("Content-Type: text/html");

header("Expires: 0");

header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");

header("Cache-Control: no-store, no-cache, must-revalidate");

header("Cache-Control: post-check=0, pre-check=0", false);

header("Pragma: no-cache");

include("conexion/conexion.php");

    return false;

  //alert(document.getElementById("form_password").value);

  return true;

}

</script>

I need to say that all started when in fact I was not sending the data due to an issue with the form and javascript. But I am confident now I am sending the data Because when I echo the post data in the server side it shows the data when I do not echo the data it says "no login information"

IMPORTANT UPDATE: I deleted the file login.php from server and I am still getting the message "No login information" from server. What is going on ? Please help

I had to merge both files in one single file and it works now
