If action is on a different page do I use fwrite function

Question

I have a form that has an action of a GET on another page.. IT also has a post method that I am using to write form data too .txt file.. When I have an action of (action="") it writes to .txt file but when I have an action on a different page (action="somepage.php?getthings") it does not write to txt file.. is there a fix to this?

<?php
//Get the email from POST
$email = $_REQUEST['EMAIL'];
$file = fopen("document.txt","a+");
fwrite($file,$email . "\n");


//redirect
?>



    <form id="subscribe-form1" action="THIS IS WHERE THE PROBLEM IS"
    method="post" class="form-inline">
      <div class="input-group">
        <input type="email" class="form-control" placeholder="Email address" name="EMAIL">

        <div class="input-group-btn">
          <button class="btn btn-grn" type="submit button" data-toggle="modal" data-target="#myModal" name="submit" value="submit" action="" >Sign Up</button>
        </div>
      </div>
      <div style="visibility:collapse;" id="subscribe-result1"> </div>
        <div class="checkbox">
          <label>
            <input type="checkbox" id="mce-group[6917]-6917-0" name="group[6917][1024]" value="1024" checked="checked" style="">

        </div>

I'm still a bit confused because you mention the use of both POST and GET. You cannot write to the mailchimp script, and I don't know exactly how your mailchimp form is configured so let's try a different approach. Let's try ajax, even though you did not tag this.

First, change the action of the form to your mailchimp URL instead of "". Then create a new PHP file:

// this is your ajax file, ajax.php


<?php

    $email = $_POST['EMAIL']; // your form method is post, no need for $_REQUEST
    $file = fopen("document.txt","a+");
    $write = fwrite($file,$email . "\n");

    echo $write ? "Success" : "Fail";
?>

Now change your button from type="submit button" to type="button".

You need to add some jQuery:

<script>

    function executeAjax() {
        $.ajax({
                 url: 'ajax.php',
                 type: 'POST',
                 data: {EMAIL: $("#subscribe-form1").find("input[type='email']"},
                 success: function(data) {
                     alert(data); return false;
                     document.getElementById("subscribe-form1").submit();
                 },
                 error: function(e) {
                     alert('There was a problem...please try again');
                 }
        });
    }

    $(document).ready(function () {
        $("button").click(function () {
            executeAjax();
        });
    });
</script>

After posting the email address to the ajax file on the backend, the file will be written. Then, the form action will be executed.
