PHP post submit not submitting

Question

I have a button that is not submitting a form via php post request. I don't understand why it's not producing the result when the button is pressed.

<?php  

    if ($_POST["submit"]){
        //$result="form submitted";
        $result='<div class="alert alert-success">form submitted</div>';
    }

?>

which is referenced from here within a html body:

<input type="submit" name="submit" class="btn btn-success btn-lg" value="Submit" />

here's the problem on a live site. the website

Answer 1

Is it possible that you just forgot to echo the result, like this:

 if ( isset( $_POST["submit"] )){
    //$result="form submitted";
    $result='<div class="alert alert-success">form submitted</div>';
    echo $result;
}
