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>

WordPress Version

<script>
jQuery(document).ready(function( $ ) {
  jQuery("#voteButton").click(function(){
    $.post("/home/xxxxxxxxxxxx/public_html/wp-content/custom-php/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>

My Custom PHP Script

<?php

const VOTE_FORMAT = "VOTE\n%s\n%s\n%s\n%d\n";
const PUBLIC_KEY_FORMAT = "-----BEGIN PUBLIC KEY-----\n%s\n-----END PUBLIC KEY-----";

$public_key     = formatPublicKey($_POST['key']);
$server_ip      = $_POST["ip"];
$port           = $_POST["port"];
$service_name   = $_POST["service"];
$username       = $_POST["username"];

sendVote($username, $public_key, $server_ip, $port, $service_name);

function formatPublicKey($public_key) {
    $public_key = wordwrap($public_key, 65, "\n", true);
    $public_key = sprintf(PUBLIC_KEY_FORMAT, $public_key);
    return $public_key;
}

function sendVote($username, $public_key, $server_ip, $port, $service_name) {


    if (php_sapi_name() !== 'cli') {
        //Detect proxy and use correct IP.
        $address = isset($_SERVER['HTTP_X_FORWARDED_FOR']) ? $_SERVER['HTTP_X_FORWARDED_FOR'] : $_SERVER['REMOTE_ADDR'];
    } else {
        //Script is run via CLI, use server name.
        $address = $_SERVER['SERVER_NAME'];
    }

    $data = sprintf(VOTE_FORMAT, $service_name, $username, $address, time());
    openssl_public_encrypt($data, $crypted, $public_key);
    $socket = @fsockopen($server_ip, $port);

    if ($socket) {
        if (fwrite($socket, $crypted)) {
            fclose($socket);
            return true;
        }
    }

    return false;
}
?>

  • That's not the correct way to deal with AJAX requests in WordPress. You should hook to the wp_ajax_ action. Anyway, if you're using chrome, what does the network tab show about that request response? – Himad 2 days ago
  • regarding the AJAX Thanks. About the network tab: I'm using firefox. The WordPress site doesn't show anything, but the network tab for my localhost looks normal. Stats of 200, Method is post, domain is localhost – ScottUSA 2 days ago
  • Can you modify the PHP script and add die('Example'); as the first line? If your request is correctly going through you should see the message as the response. – Himad 2 days ago
  • okay, I added that to the PHP script and nothing. I know the button is working. So, it has to be the JQuery. I checked page source and I can see my JQuery script in the header and it looks good. I guess I have to learn AJAX for WordPress. – ScottUSA 2 days ago

    Your url is definitely wrong. You are trying to access a server path instead of an url. $.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.com/wp-contents/custom-php/votifier.php – Hannes 2 days ago

Function: 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:

Firefox Network Params Firefox Network Headers

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()

                    ,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 enter image description here

When I click on the link in the footer, I see the JQuery: enter image description here
