PHP unable to receive Javascript variable via Ajax -

solved: didn't realize ajax sent data in instance , redirecting created new instance.

i looked through stackoverflow results none of works.

i trying send variable mmm php via post , reason php doesnt retrieve it. don't know doing wrong.

here javascript code (in file checks.js):

$.ajax({    type: "post",    url: 'https://www.example.com/panel/app.php',    data: {mmm: 145},    success: function(data) {       alert("success");    } }); document.getelementbyid("adminloginform").submit(); 

here php code in file (app.php):

<?php    $output = (isset($_post['mmm'])) ? $_post['mmm'] : 0;    echo "<script>console.log( 'debug objects: " . $output . "' );</script>"; ?> 

google console log prints: "debug objects: 0"

the file directory follows:

main folder

• base

  • registration

    • login

      • base

        • js

          • checks.js

• panel

  • app.php

ajax means not doing form submission browser action, refreshes page. try rid of line , run code document.getelementbyid("adminloginform").submit();. may alert success.

$.ajax({    type: "post",    url: 'https://www.example.com/panel/app.php',    data: {mmm: 145},    success: function(data){       alert("success");       console.log( 'debug objects: ' + data )    } }); 

and change php script echo $output.
