My code is working fine on my localhost in my development environment which is outside of the WordPress press environment. I know the PHP function is working. I am able to send test votes to my server from my localhost on my PC.
Problem: I cannot get this to work in WordPress.
My Thoughts I think it's a path issue, but I've tried putting the PHP script in the root and using a full path. I am not getting any errors in the web browser console (f12).
WordPress Version: 5.4.1 I put my custom php code into "/wp-contents/custom-php/votifier.php" My JQuery script is in the header. (yes, I know I should put it in the footer.)
The Button
<div id="voteButton">
<button type="button">Try it</button>
</div>
Localhost Version
<script>
$(document).ready(function(){
$("#voteButton").click(function(){
$.post("votifier/votifier.php",
{
key: $.trim($("#field_yjr62").val()),
ip: $('input[name="item_meta[40]"]').val(),
port: $('input[name="item_meta[42]"]').val(),
service: "Votifier",
username: $('input[name="item_meta[59]"]').val()
},
function(data,status){
alert("Data: " + data + "\nStatus: " + status);
});
});
});
</script>

Reset to default -1Function: The user clicks a button on a webpage
Action: The click should connect to an external server using the following params:
1. User Name 2. IP Address 3. Port 4. Public Key 5. Service
The PHP code is still not sending the vote to my external server. So, I tried a slightly different approach. That is, I am trying to use the wp ajax action.
The Server side PHP is the same (see above).
I have Wordpress in debug mode, but I'm not getting any errors.
I'm using Firefox and the form data looks good:
HTML CODE
/* XXXX HTML BUTTON XXXX */
<div id="frm_field_61_container">
<button type="button">Test Vote</button>
</div>
JQuery AJAX
/* XXXXX JQuery / AJAX Call XXXX */
jQuery(document).ready( function($) {
$("#frm_field_61_container").click(function(){
nonce = 'votifier_response_key';
jQuery.ajax({
type : "post",
dataType : "json",
url : myAjax.ajaxurl,
data : { action: "my_vote_count"
,key: $.trim($("#field_yjr62").val())
,ip: $('input[name="item_meta[40]"]').val()
,port: $('input[name="item_meta[42]"]').val()
,service: "Votifier"
,username: $('input[name="item_meta[59]"]').val()
,nonce: nonce},
success: function(response) {
if(response.type == "success") {
alert("Your vote was counted!")
}
else {
alert("Your vote could not be added")
}
}
});
});
});
WordPress - functions dot php file
/* ===== WordPress Java Script Registration ==== */
add_action( 'wp_enqueue_scripts', 'my_script_enqueuer' );
function my_script_enqueuer() {
wp_register_script( "my_voter_script", get_stylesheet_directory_uri() . '/js/sendvote.js', array('jquery') );
wp_localize_script( 'my_voter_script', 'myAjax', array( 'ajaxurl' => admin_url( 'admin-ajax.php' )));
wp_enqueue_script( 'jquery' );
wp_enqueue_script( 'my_voter_script' );
}
/* ===== My Votifier Code ==== */
add_action( 'wp_ajax_my_vote_count', 'my_ajax_handler');
add_action( 'wp_ajax_nopriv_my_vote_count', 'my_ajax_handler' );
function my_ajax_handler() {
check_ajax_referer( 'votifier_response_key' );
echo "Thank You for your Vote!";
wp_die(); // All ajax handlers die when finished
}
JQuery is Registered and showing up in the footer
When I click on the link in the footer, I see the JQuery:

wp_ajax_action. Anyway, if you're using chrome, what does the network tab show about that request response? – Himad Commented May 23, 2020 at 0:44die('Example');as the first line? If your request is correctly going through you should see the message as the response. – Himad Commented May 23, 2020 at 1:14$.post("/home/xxxxxxxxxxxx/public_html/wp-content/custom-php/votifier.php",. Can't you just use/wp-contents/custom-php/votifier.php? If you output something in your PHP file you could check whether or not it is reachable by just entering the full url in your address bar bestlist/wp-contents/custom-php/votifier.php – Hannes Commented May 23, 2020 at 12:03
