post value from one page to multiple page in php - php

Question

referral-page.php
I have submitted email data and store in DB and then goto Primary page
<form action="store-db.php">
<input type="text" name="email" />
<input type="submit" value="Submit" />
</form>
I have stored email data in DB using ajax ( this was completed ). but I want to post email value to primary-page.php
primary-page.php ( email field should be prefilled if I come from referral otherwise it should be empty value )
<form action="thank-you.php">
<input type="text" name="name" value="" />
<input type="text" name="email" value="<?php echo !empty($_POST['email']) ? $_POST['email'] : ''; ?>" />
<input type="submit" value="Submit" />
</form>

Answer 1

After the ajax call to the DB has succeeded, why not just redirect to the thank you page, sending the email address in the query string ($_GET)?
Or maybe better: just submit to the php page and do the db storage there, before outputting "thank you" or "error"?

Answer 2

myself form action changed to primary-page.php
<form action="primary-page.php" id="primary_page">
<input type="text" name="email" />
<input type="submit" value="Submit" />
</form>
1) data validate and stored in DB using ajax ( store-db.php )
2) email value post to primary-page.php using function frm_submit()
var form_validate = $("#primary_page");
form_validate.validate({
rules: {
email: {
required: true,
email: true
}
},
submitHandler: function () {
var param = form_validate.serialize();
var btn_submit = $("#submit");
$.ajax({
type: "POST",
url: '/store-db.php',
data: param,
cache: false,
dataType: "json",
success: function (response) {
frm_submit();
}
});
});
function frm_submit() {
form = document.getElementById('primary_page');
form.submit();
}
